The month of August was both productive and fascinating. While we were busy doing seed collections we had the opportunity for exploring the land and seeing some amazing sites, as well as collaboration.
We worked with our partners in the Rocky Mountain Research Institute (RMRI) conducting vegetation surveys in many of the Northern reaches of Nevada. With their help, we formulated and tested vegetation surveys that will be carried into the future to affect the management of both BLM and USFS properties
We had the opportunity to learn and exchange knowledge with our partners as well as enjoy working with people who share a similar passion. After our work with them was done we took the time to explore our own districts. There is always a lot of ground to cover in such a big state. We had much success, and have had the opportunity to meet fellow botanists and interns in the ‘wild’.
I am starting to get low on these Wyoming puns. Haha. I officially have less than three months left in Lander, and am already feeling the pressure to see everything left on my Wyoming bucket list… and it’s pretty long. But! A couple weekends ago, Johnny made it back to WY and we started to make a serious dent in it. I had never been East of the Casper/Natrona County International Airport so that weekend we explored smaller cities that were past Casper, like Glenrock and Douglas. We made our way through Glenrock pretty quickly, after we stopped at their Paleon Museum for a short while. About half way to Douglas, we drove South off the highway to see Ayres Natural Bridge in Converse County. I saw my first herd of buffalo ever on the way into the park! I’m not sure if they were wild or not, but they were magnificent. Even from the road, we could tell just how massive they were. Once we got to Ayres Natural Bridge State Park, we climbed a small trail up the side of the bridge and found a huge rock pillar at the top of it. The rest of the view up there was really nice too. š After admiring the natural limestone arch, we made our way to Douglas. At this point we were about 3 hours from Lander, so we didn’t spend too much time here. Once we had walked through a couple of museums, we started our drive back home, but stopped at one last destination back in Fremont County called Castle Gardens Petroglyph Site. I had heard of petroglyphs being in Thermopolis, but hadn’t had time to go find them whenever I’ve visited in the past. When I heard there were some closer to Lander, I was thrilled! The petroglyphs at this site are rock carvings made by Athabaskan Native Americans from some time between 1000 and 1250 AD. They carved images of animals, plants, medicine, and other important cultural symbols into several of the outcroppings of rock there.
The next afternoon, we decided to go back to one of our favorite spots to watch the sunset at The Bus again. This is one of the most popular mountain biking/hiking destinations in Lander, and is known for that old wrecked bus Johnny found in a ditch about a month ago.
The next day, we ventured back into Sinks Canyon State Park for the day. We started on the Popo Agie Nature Trail, and then after about a half mile, we veered right for the 1 mile North Slope Trail. This trail is only open once it is dry enough in the summer, and takes you from the Nature Trail, up a steep ascent up the canyon, and then back down. It passes right over the natural sinks that the Popo Agie River disappears into, and brings you right to The Rise trout pool. This was Johnny’s first time seeing The Rise, and we were lucky enough to see a muskrat feeding among the trout!
My next week was spent with Jon keeping up with our usual rangeland monitoring studies, as well as contacting one of our permittees about unknown cattle brands. This was one of the last weeks Jon and I spent together before he went out in the field with Grant, our newest Rangeland Specialist, to teach him about the huge allotments he would be in charge of. During this week, our whiteboard broke into shreds, as you can see in the photos below. I couldn’t stop laughing at ourselves and our supplies we were working with, but nevertheless, we got the job done as usual. When I contacted one of our permittees, I was communicating with a very nice rancher named Travis Clyde. We had been trying to decipher about five pages of cattle brands I had put together, for months, so we decided to try asking somebody who may know more about it than we did. There were at least two to three dozen brands we just did not have records of, so Travis definitely helped us in validating them.
The next weekend, we went to the town of Ten Sleep, which is about two and a half hours North/Northeast from Lander. There was a really fun volunteer opportunity I had heard about through the BLM for trail maintenance at Salt Lick Trail just outside of downtown Ten Sleep. We camped out Friday night nearby, then woke up early Saturday to help out. We spent the morning digging out steps and tossing loose rocks over cliffs, all to make the trail a bit more safe for visitors. Afterwards, a very nice couple that lived at the bottom of the trailhead invited us to their home and made all of us burgers and endless picnic food. Johnny and I headed back home a little while after lunch, and made a quick stop in Thermopolis so he could enjoy the free Bath House in town, and learn about the “World’s Largest Natural Mineral Hot Spring”.
The rest of that weekend was spent resting and taking a hike around Frye Lake, one of my favorite places to visit in Shoshone National Forest. I had never made a full loop around the lake so Johnny and I were excited to try it. We ended up walking about 2+ miles around it straight into the woods. Eventually, it started getting dark, so we decided to turn around, witnessing a pretty incredible sunset on our way back to my car.
The following week, Jon and I finished up our rangeland monitoring duties in our second allotment, Antelope Hills. We also got a chance to go out with several Rangeland Specialists from the Lander field office that week to learn the Utilization Training method for our allotments. Every year, around September when the pastures get emptied of cattle, the BLM goes back into them in order to record how much the grasses were actually grazed/utilized in each allotment. These data are very useful for short-term, and longterm, monitoring of the lands we have to manage. We used the “Landscape Appearance Method” to do this, in which we studied the grasses in several different areas of the allotment, to estimate a percentage, or color, of grass utilized. This means we drove and walked around almost the entire pasture, running transects and recording whether the grass in the area was grazed at 0-5, 6-20, 21-40, 41-60, 61-80, 81-94, or 94-100 percent. These seven categories were split into five larger categories in order to make our job a bit easier later. This is because after we get these data recorded, we take a huge map and literally color it with five different colors: red, orange, yellow, green, and blue. Red represents the most utilized/grazed areas of a pasture or allotment, and goes all the way up to the cool colors where blue represents almost no grazing of an area of grass. These maps are great for the specialists to compare year-to-year, and to find patterns, when necessary.
I have still continued to learn so much from the BLM, and I’m confident I will keep doing so. I can’t wait to see what other kinds of opportunities I get to experience with them, and I can’t wait to keep using my weekend time WYsely to enjoy all the other magnificent parts of Wyoming. š There is never a dull week here, and I am so fortunate for that.
August and the last week or so in July
have been just as adventure filled as my first 4 months with the BLM in
Fairbanks, Alaska. Invasive species were getting awfully close to seed by the
time we made it out to pull along the Steese and Taylor Highways in the Eastern
Interior; and though we only saw a dozen or so Caribou, we had to fly out in a
helicopter to access areas in their range not disturbed by humans; thankfully
the only SOS signals needed on any trip were related to Seeds Of Success. Barring
a very windy night up in the White Mountains that caused one tent collapse, and
a near sleepless night for everyone up there, that is.
Even the most conspicuous and damaging invasive plants in Eastern Interior Alaska are somewhat limited in their impact to date. I say this with caution, however. In most of the lower 48 states and much of the colonized world, invasive species are only given serious attention once their eradication is nigh impossible. In other words, itās almost too late. This isnāt to say invasive treatments arenāt worthwhile in those places, just that they cost billions to manage because of the damage done to crops and native habitats – in the US $120 billion a year to be exact (Pimental et al., 2005). In Alaska, at least from what Iāve seen, invasive plant populations are limited to roadsides and cities ā of which there are relatively few. What I do see because of this, is a great opportunity to make an impact on removing these species before they become a more serious problem; and even more time, resources, and money have to be thrown at tackling it. Without intervention, it wonāt take much for seed to be carried away down streams and rivers, and plants like Melilotus alba (white sweetclover) and Vicia cracca (bird vetch) to begin overcrowding riverbanks as they do on the highways we targeted.
Getting to that, our āweedā pulling began on the Steese Highway at various BLM managed waysides such as those at the Upper and Lower Birch Creek. We stopped at each wayside along the way to monitor, but there were only a few that had infestations of the most damaging species. Interestingly enough, the furthest wayside from Fairbanks had the worst white sweetclover infestation of any! They must have hitched a ride from an unknowing driver, or perhaps in gravel used for the lot. These guys produce an average of 9,710 seeds (Klemow and Raynal, 1981; Klemow, 1982), though some estimates suggest as high as 350,000 per plant. The most concerning factor is that each of those seeds can remain viable for up to 81 years (Crocker, 1945). The picture below is one of the bigger white sweetclover I pulled. They grow in thick patches, sprouting early to overshadow their competitors and developing tap roots that quickly drain moisture from the soil.
The following week we drove up the Taylor Highway toward Chicken, stopping along the way to pull more white sweetclover on BLM land between mile-markers 4 and 6. I was lucky enough to have a previous CLM internās notes to go off when planning our invasive trips this summer ā it was a huge help! After pulling those weeds we drove further up the Taylor to the Department of Transportation (DOT) South Fork Station. This sits at the South Fork of the Fortymile River ā the same section of river I floated on earlier this summer ā but just across the road. Between the road and the fence, and following the road up to the wayside, is BLM managed land. But on the other side of the fence is state managed land ā the DOT Station. In what turned out to be a dichotomy here and perhaps representative of more issues than I should dive into, I found an interesting lesson in land management.
From the same notes I mentioned
before, the previous intern and now retired biologist had discussed their
frustrations at pulling bird vetch on the BLM side of the fence whenever they
could because on the DOT side the same invasive species persisted. Talk about
futile efforts. I canāt imagine spending a day removing an invasive plant from
one side of a fence only for the same vine-like shrub to wrap its tendrils
around the wire and have its seed blown onto where you just pulled a few weeks
later. When I read this, I remembered a meeting Iād attended earlier in the
summer about invasive species management on the Dalton Highway (this road runs
through a different field office than the one Iām assigned to but I thought it
would be worthwhile to go). At that meeting was someone from the DOT ā perfect,
I just needed to get hold of them and of course theyād help us eradicate bird
vetch from both sides of the fence! Right?
Well, kind of. After exchanging a few emails, I was told that while they couldnāt support the invasive pull with staff or resources, they would allow us to come and pull weeds on their side of the fence. It just had to be approved by a few higher ups, and they needed to know what day weād be there to do the work. While this wasnāt exactly what I was hoping for, I thought great, at least we can get the work done and maybe next year weāll get a bit of help! Inter-agency collaboration between the state and federal government is a work in progress, but I’m hopeful.
When we arrived to pull, the staff was happy to let us in and get to work. Bird vetch is a tricky plant to remove as it reproduces both through seed and through rhizomes. This means you need to remove as much (ideally all, though not usually possible) of the root system. Yanking the plant out the ground is thereby ineffective because it simply snaps at the base. A more effective, albeit more time consuming, approach is to slowly pull from as close to the ground as you can and work the root system out of the ground. Naturally this became a competition to see who could remove the longest root!
Following several other weed pulls, I was off to help out a different BLM biologist conducting caribou habitat surveys in the Fortymile and the White Mountains. In partnerships with PhD students and the NASA Arctic-Boreal Vulnerability Experiment (ABoVE), the project has several goals oriented around improving our understanding of caribou impacts on native arctic alpine vegetation, and mapping biomass of plant functional groups with drone assistance. Because of the limited road systems in Alaska, and perhaps one of the most fun things Iāve been lucky enough to do this summer, reaching remote locations for studies such as this one requires travelling via helicopter!
Once we arrived at our randomly selected site, it was straight to work setting up the plot. I say that but often the plots were already set up upon my arrival ā I had to fly alone because of something to do with weight limits in these little helicopters! My helicopter diet started a little too late apparently. You can see below some of the beautiful views we got to work above:
Caribou tend to eat a considerable amount of lichen among certain shrubs, graminoids, and occasionally mushrooms. As such, lichen identification was a huge part of this project ā something I have had relatively limited experience in. Jim, Katie, and Rachel were super helpful in getting me up to speed nonetheless, and after a few days of staring into quarter meter plots identifying, estimating cover, and then trimming biomass of all vegetation, I had them just about down.
After a site was completed, which took most of a day, the helicopter would fly us to our next site where weād set up camp, make some dinner, and chill out before starting a new plot nearby the next day. Weather dictated a lot of what we could get done with the need for a drone flyover prior to trimming any biomass. In the mountains that we surveyed, where weather is about as unpredictable as can be, this meant for a couple of days spent waiting in the tent for openings in clouds or fog. The drone canāt capture usable imagery without clear line of sight to the ground.
A couple of days in the tent out of seven waiting for clear skies werenāt the only times weather worked against us either. On our second night in the White Mountains we knew there was a chance of strong winds and rain, which is why we camped down off one of the ridges in what looked like a well shielded valley. Unfortunately these winds were stronger than expected. That, or our campsite was more exposed than we had anticipated. The work tent I lent to Rachel only lasted about half the night before the guyline snapped under the force of the wind (likely the guyline that a squirrel had partially chewed into earlier this summer!). Shortly after, one of the tent poles snapped as well, ripping a hole in the tent and collapsing it all at once. She managed to grab her belongings, find her way ou tof the fallen tent, and run down into the gear tentā a fortress of a dome tent which went relatively unphased by the gales.
Meanwhile, I was wrapped up in my sleeping bag hoping my tent would make it through the night. The wind didnāt blow constantly, nor did it always blow in the same direction. There were moments where only the pitter-patter of rain could be heard. Then a sudden crash blew into one side, followed by a smashing of wind into the other. I probably slept a total of 2 hours that night. Periods of sleep would be interrupted by the tent pole above my head collapsing down onto me under the force of the wind ā not exactly conducive to quality REM. Thankfully my tent made it through the night and so did Jim’s, none of our gear got terribly wet either. All in all it was a wild night that we laughed about in the morning over coffee in the dome! The next day wind and rain continued, though at a much gentler pace. We moved our tents down even lower into the valley below another plateau. Thankfully this was one of the days spent in the tent waiting for clear weather, and occasionally napping as we recovered from the prior near sleepless night!
Compared to the invasive species work and caribou habitat surveys, collecting seeds for the national Seeds of Success program went off without a hitch! One of the targeted species was Arctostaphylos uva-ursi, otherwise called Kinnikinnik, or Bearberry. Thereās a huge population of this low growing shrub near the small town of Tanacross, Alaska, so thatās where we drove to gather seed. The goal of 20,000 seeds per species sounds quite daunting at first, but considering there are multiple seeds per berry makes the task more manageable. Iām sure many other CLM-ers have been out collecting too, and hopefully in good conditions! We had a beautiful sunny day to pick berries and collect a couple of herbarium samples, and quite enjoyed the relaxing pace of doing so. The only thing that could have made the day any better would have been if the berries were more edible ā Kinnikinnik have the texture of lint if you bite into one! A native group called Gwichāin would eat the berries mashed up and mixed with dried fish or roe in a sort of pemmican, while the Denaāina would mix them with oil or lard. They preserve quite well and maintain their nutritional value this way. Apparently the berries were also important as a food for survival when Alaska first became colonized, though Iām thankful not to have had to depend on them for sustenance. Trying one was more than enough!

We began the month doing Wyoming Toad (Anaxyrus baxteri) surveys once again. However this time instead of breeding surveys, where we were looking for tadpoles and egg masses, we surveyed for the adult toads specifically. The procedure is mostly the same with the exception that the plots we were surveying extended farther from the waters edge. When we captured a toad we measured lengths and mass and took a sample for chytrid fungus. This fungus causes an infectious disease in amphibians called Chytridomycosis which is believed to be a factor in the global decline in amphibian populations and is possibly a factor in the decimation of the Wyoming Toad population in the mid 1970s.
After toad surveys, I assisted fisheries with their seining surveys. Seining is a method of catching fish using a seine, which is a net with poles fixed to either end, a weighted bottom and buoyed top. The net is dragged along either side of the shore and many of the fish in the river get trapped inside. We were doing a depletion removal study to estimate the actual abundance of fish species. This consists of three successive passes done with the seine per site and the number of each species of fish that was caught was recorded. If done correctly each pass should yield less fish then the last and the rate of decline can be used to determine species abundances. I also had my first experience electroshocking which is another method to determine fish species abundance. In this method, one surveyor administers a non-lethal shock to the water with an backpack electrical generator to temporarily stun the fish so the other surveyors can net any observed fish. Again three successive passes are done per stream section and actual abundance can be determined.
One of the most compelling things I did this month was Black-footed Ferret (Mustela nigripes) surveys. These remarkable animals are North America’s only native ferret and were once considered to be extinct until one was caught by a farmers dog in Meeteetse, WY in 1981. Since the discovery of the extant population, many breeding and reintroduction efforts have been underway to save the population and have been considerably successful. Black-footed ferrets main food source is prairie dog and they use their burrows to hunt, sleep, hide from predators, and reproduce. The ferrets historic range coincided with that of the prairie dogs. The project I was helping with is managed by the Wyoming Game and Fish Department and we were surveying the Shirley Basin population. The goal of the surveys was to attempt to determine population size but also to tag and vaccinate as many ferrets as possible. Surveys took place from 7pm until 6am as the ferrets are nocturnal. Everyone was given a section of land to survey and spotlights were used to locate eye-shine. Black-footed ferrets eyes appear an emerald greenish blue when light is shinned on them. Once a ferret was located it was followed until it entered a prairie dog burrow and then a trap was set in the entrance of the burrow and all other exits from the burrow were plugged. The trap site was then checked once per hour for any trapped ferrets. When a ferret was capture it was transferred to a tube that resembled the inside of a burrow and it was brought to the processing trailer where measurement were taken and vaccinations were administered. Once processed, the trap set up was disassembled and the ferret was released where it was captured. Over three nights of surveying I caught four ferrets, two female kits, a male kit, and a young adult male. Between the 10 survey areas 16 ferrets were captured and processed. We also observed many incidentals, including badgers, swift foxes, red foxes, coyotes, pronghorns, jack rabbits, and ferruginous hawks. Getting to work with and observe such an iconic species in the wildlife conservation world was an absolutely incredible experience and I couldn’t be more grateful that I got to assist in the conservation efforts for the species.
For the last half of August we completed our second round of trapping for herptiles North of the Ferris Mountains. This trapping period was great for garter snakes (Thamnophis elegans) as we trapped around the time that females were giving birth. Many of the garter snakes we caught this period were young of the year. We also caught our second Northern Leopard Frog (Lithobates pipens) which was an excitement. My most exciting opportunistic catch this period was a three foot long bullsnake (Pituophis catenifer sayi)! I also had the opportunity to tube and process a Prairie rattlesnake (Crotalus viridis), which was an incredible learning experience. The rattlesnake was a small female caught outside the office so we relocated her to one of out trap sites. Unfortunately we couldn’t count her in our data but fingers crossed we can catch her again later in the season. We added some sherman traps to three of our sites in an attempt to trap more mammals but they were much less successful then I was expecting based on past experiences. Only one deer mouse was captured who unfortunately had succumbed to the environment. Overall for mammals we caught plenty of deer mice and voles, plus a hand full of shrews. Overall it was a good trapping period but I am hoping for an increase in diversity for our next, and last, trapping period.
The day that my crew now knows simply as “Thursday” started like any other day. We were scheduled to do monitoring on two long-term range plots northwest of town. The drive out there was going to be about an hour, so we got to the office and headed out right away. Driving to the first plot, we were about 10 minutes away according to our GPS, and we hit a huge ditch in the road that we weren’t confident driving over. We weighed our options and decided to load up our packs and try to hike to it. After about 5 minutes of walking, we reached a tiny road that we realized connected back to the highway and could take us to our plot. Rather than walk 4 miles round trip, we walked back to the truck, hopped in, and made it to our plot via a small two-track road. We finished our protocol, had lunch, and were ready to tackle the next plot.
The second plot we planned to complete that day was only 2 miles away as the crow flies, but of course in order to drive there, we had to drive over an hour on roads with boulders and rock slabs. In the Carlsbad Resource Area, roads are constantly changing and moving because of the oil and gas development, so we had to turn around two times to follow roads that were not on our map. The road that our second plot was allegedly on had completely disappeared, so we took a gamble and followed a road not on our map to get as close as possible to the plot. At this point, it was already 4pm, there was a thunderstorm fast approaching, and we were on an exposed ridge.
Fortunately, we found the plot rebar, collected our data, and were back to the truck before the storm got too close. The road we had been on looped back to highway, so we decided to continue the direction we were going rather than try to drive over the horrible roads we’d already driven on. We messaged our supervisor that we would be late and started making our way back.
Initially, the road seemed great. Not as many rock slabs, easy to follow, and we even saw a javelina (small wild pig) run down a draw right in front of our truck. Once we got about 5 minutes from the highway, we hit a roadblock. In front of us was a 12 inch drop into loose gravel at the bottom of a draw, an uneven hill on the other side. At this point, if we had to turn around, we wouldn’t be back to the office until about 9pm and would have to drive horrible roads in the dark and potentially the rain. We weighed our options, and decided to get out of the truck and see what we could do. As we looked at the draw, before we all decided to get out, my crewmate Alex said, “Snake? Rattlesnake!”. Off the driver’s side corner of the hood, curled up behind a rock, was a beautiful rattlesnake. It uncurled itself and slithered off the road into the bushes, all 4 feet of it disappearing into the brush.
We still didn’t want to turn around, so as my crewmates Alex and Catherine got out and began moving rocks into the draw to lessen the drop, I kept my eyes on the surroundings, making sure the rattlesnake didn’t come back. Before we made the move to drive over the draw and our makeshift road, we noticed a house up on the hill by the draw and noted that if something went horribly wrong, we could go to the house and ask for help. We heard a dog barking, so we knew the home was inhabited. Then we started the truck. Apparently my crew has secret roadbuilding skills, because our truck made it through the draw and we continued down the road toward the highway. Then we saw a gate.
I got out of the truck to open the gate, which was unlocked and blocking the county road we were on that went through to the highway. As I walked up to the gate, I heard an engine start. Up drove a man in an ATV. It was perhaps the strangest encounter with a person I’ve ever had. He repeated, “It hasn’t rained out here in 3 years” in a slow Southern drawl about 3 separate times in our conversation. After about a 5 minute talk he drove away and we proceeded through the gate, drove 3 more minutes, and hit the highway. We got back to the office unscathed and only an hour and a half late.
Just about every safety talk they give you at the Carlsbad Field Office came to our minds that day – horrible roads, roads not existing anymore, thunderstorms, rattlesnakes, strange men living in the middle of the desert. We maneuvered around every challenge and ultimately I think our crew became closer because of it. And we went to get ice cream afterwards, so at least we ended the day on a high note.
This past month we have been spending a lot of time at the
Curlew National Grasslands for a very special reason: Monarch butterflies.
The Curlew is a grassland managed by the Caribou-Targhee
National Forest and is composed primarily of agriculture land that was retired decades
ago and now serves as expansive, rich habitat for a whole slew of species. It
is a very special place whose location in southeast Idaho gives it the unique
ability to serve as part of the highway for western populations of monarch butterflies
during their yearly migration to California. Monarchs flock to the Curlew to
rest, mate, and start a new generation in the shade of its riparian areas that
are chock full of showy milkweed (Asclepias speciosa).
Unfortunately, loss of habitat and food sources have caused
monarch populations to plummet. The western population is really struggling and
where thousands upon hundred thousands of monarchs used to pass through the
western United States now only a few hundred or thousand are seen.But the Curlew
hasnāt given up on Monarchs yet! It still welcomes them with the promise of
shade, food, and a possible mate in the area. For that reason, monarchs are
still flitting through the expansive grassland.
As interns on the Caribou-Targhee we had the privilege of
partnering with state agencies and citizen scientists to document the monarchs
passing through the Curlew this year. (Here I was, thinking I would never see
or experience what it is like to see monarchs migrating when suddenly I am
thrown right into the science behind tracking and monitoring them!) Monarch
surveys occur all over the United States and are fueled by the research and
work of people like Dr. David James and organizations like the Integrated
Monarch Monitoring Program-thankfully, there are a lot of people that care
about monarchs š
Preforming monarch surveys means gearing up with butterfly
nets, data sheets, sunscreenā¦and lots of waterā¦and then getting to work. And let
me just say, catching a butterfly is not as easy as it seemsā¦but when you do
finally catch one you cannot help the smile that spreads over your face, itās
the best combination of science and feeling like a kid again. Gently reaching
in and grasping the little migrant in the proper way and sliding them out of
the net is a surprise in and of itself because suddenly the vibrant colors of
their wings and sharp white polka dots on their black body are no longer muted
by the mesh of the net or the haze in the air. And my goodness are they are
exquisite. Some of them are more tattered and torn around the edges letting you
know they have come to the Curlew to mate and continue the migration through
their offspring while others are almost fluorescent in color and itching to
travel.
The butterfly patiently grasps your fingers as you attach a small tag to the proper area of its wing (so that its flying ability isnāt hindered) and reluctantly allows you to open up its wings (with which you get another pleasant shock of wonder as their deep orange wings, rimmed and webbed with velvet black, completely open in front of you) and look for the presence or lack of a small black dot on each wing. If the monarch has these dots it is a male (other butterfly speciesā males emit pheromones from these dots of specialized scales, but the jury is still out on what monarch males use them for) and if not, it is a female. After checking that you have written down all the necessary data you slowly detach your fingertips from their wings. At this point, it is a 50/50 chance whether the monarch will leap back into the sky immediately or stay on your finger for a bit, gently flapping its wings and making up its mind (all to your complete delight). Experiencing monarch butterflies in such a hands-on manner was amazing-something I never thought I could have done!
But we donāt just pay attention to the adults; monarch
surveys also include searching for instars on the milkweed plants and tiny
monarch eggs. This means recognizing monarch instar leaf grazing and peering
over and under the soft milkweed leaves in search for the happy culprit. When
an instar is found you can tell what stage it is in by the presence or lack of
stripes and antennae. Data is recorded and the instar grazes on; you can almost
see it growing in front of your eyes as it chops away leaf after leaf! Monarch
eggs are a bit harder because spots of dried milkweed latex on the leaf can
fool you repeatedly. But when you finally find an egg, you realize that they have
an incredible design: small and rounded at the bottom with a slight Hersheyās
kiss top and vertical lines traveling up across its entire surface. Perfect
looking and so small you must confirm it using a hand lens! We also care a lot
about monarch habitat and need to document the characteristics of the areas
they frequent in order to better understand how we can remediate the loss in
their numbers. This means walking transects and using vegetation frames to
collect data on the landscape that the monarchs love. The healthy mix of nectar
plants, milkweed, and shade trees on the Curlew is what the monarchs really
seem to key into in southeast Idaho!
Thanks to interagency collaboration and the help of citizen
scientists the presence of a special section of western monarchās migration highway
at the Curlew was confirmed again this year with notably high monarch counts
for the entire western half of the Unites States. I was so happy to be a part
of it š
Already
unsteady on the invisible rocky surface, I found myself falling backwards as I
stepped into the fast moving channel. Catching myself on a willow tree, I didnāt
quite end up submerged, just pleasantly spattered by the cool water of the
Tongue River. It was my first day out in waders on the river, and I was
determined to not make a fool of myself as we collected data for an upcoming
bank restoration project. The river had been showing signs of increasingly poor
conditions for years, but before any restoration work could take place, the one
hydrologist in our BLM office needed to perform some 20 different analyses
along 300 points per river bank for his report. So, although a plant biologist
and rec intern, I was gladly roped into the world of hydrology to help.
Our first
day out at the river was spent establishing the data collection points every
300 feet along the river. This was before we ordered the waders, so my fellow
intern and I covered the land-based jobs while the hydrologist dutifully hiked
up and down the river measuring the distance. We would run to and from the truck,
making metal caps with the proper distances stamped on them, grabbing spray
painted blue posts to mark these metal monuments, and collecting GPS data on
the fancy Trimble unit we were using for the project. It was when I found
myself squeezing through dense stands of willow trees to reach the hydrologist
and hand off our many tools that I truly felt happy; while I have enjoyed my
experiences in sagebrush country, here, slogging through trees with twigs in my
hair and mud flecking my face, I felt at home surrounded by plants being useful.
And we were useful. By the end of the day, the hydrologist officially signed us
on to the project and ordered the waders so we could really dive in.
It was a
hot, muggy day when I first tried out my waders. They are made of Neoprene, a
very thick buoyant material that, I quickly learned, are not suitable for any
land hiking on hot days. Only in the cool water is it tolerable, although the
pressure from the river makes it feels like youāve vacuum packed your legs in
an attempt to keep them dry. Our task for the day was to make bank assessments
for every distinct section of the river. These assessments included taking note
of the bank height, root depth and density, surface protection, sediment types
and degree of stratification for these sediments. Each of these categories received
a numeric value which, when manipulated according to a template, would give you
an overall rating for the health and stability of each section of the bank. It
is a somewhat rough estimate of health, however, as you are supposed to apply
each set of observations to a given section of stream; making these assessments
at every point along the river would be time consuming, absurd, and not
effective in the long run due to the ever-changing bank geography.
As we
hiked the river (downstream, the more energy-sensible direction), the
hydrologist pointed out features of the river for which I never had official
vocabulary before. Pools, well-known as the deeper areas of rivers, turn into
glides, or smooth areas of fast-moving water. These are followed by riffles, or
shallow areas where fast-moving water is agitated by rocks, and then go into runs
which make up the main body of moving water. These four areas repeat all down
the river and once you recognize them, you begin to recognize the various types
of erosion or deposits that are associated with each. There was also bizarrely
a lot of car parts protruding from the banks. When I asked about it, I was told
that dumping cars on the sides of banks and covering them with soil used to be
a widespread restoration method in the 1950s, resulting in many rivers across
the country with old decaying cars randomly popping up. They provide a tough
problem: on one hand, they are polluting the river and becoming dangerous debris
while on the other, many of them are still doing their job stabilizing the
riverbank. Our hydrologist will have to make the call as to whether we will rip
up the bank to get at the semi-revealed cars, or if we will wait for a future
restoration project to do that.
I am very happy to be working on this hydrology project. It gives me the opportunity to learn about a system which Iāve never really focused on before, as well as asking an expert millions of questions that he has been kind enough to answer. We will continue working on river data collection for the next two month, by which point Iām sure I will love the warmth my Neoprene waders provide. Until then, Iāll just rock the sweaty end-of-summer look. And it truly is a look.
As I’m nearing the end of my internship, I expected the season to slow down significantly. However, my co-intern and I are still finding ripe seeds (with the help of our mentor of course!). Since my last blog post, we have finished a collection of Astragalus bisulcatus (twogrooved milkvetch), which accumulates selenium in its tissues. Although the selenium did not harm us at all while collecting, it emits a terrible odor which made the collection process slightly less enjoyable than most of the others. Luckily, we had found an area with so many plants that the collection was relatively quick. South of our field office at a higher elevation is a site called Green Mountain, which has proven to be a wealth of later season fruits. Some of the species that we have recently collected there have included Mimulus guttatus (seep monkeyflower), Penstemon procerus var. procerus (pincushion beardtongue), and what we believe to be Juncus confusus (Colorado rush), Thermopsis rhombifolia (prairie thermopsis), and Juncus ensifolius (swordleaf rush). The Mimulus guttatus and Juncus ensifolius were especially interesting because they were found in a pocket of fen or bog on the side of Green Mountain. I would have never expected that we would be able to collect those species this season, and even less so near the top of a mountain. I was so excited that I forgot to test each step before putting my full weight down and ended up getting one entire leg stuck (see picture). My co-intern and I laughed until tears ran down our faces as she helped me scrape the mud off of my pant leg.
Green Mountain also stands out in my mind this past month because we got to see about 15 wild horses in three different groups. One of these three groups consisted of a mare with her colt who was probably only a year or so old. The mother allowed us to get within only 5 or 6 feet of her, and didn’t seem to mind us at all. Our presence made her foal very nervous, however, and he ran and hid behind his mom more than a couple of times. But after a short time, his curiosity got the best of him and he too got close to us. Having had two horses in the past, I consider this to be one of the most exciting days of my internship, and I hope to see more horses at Green Mountain before leaving.
I have also enjoyed having the opportunity to show visitors some of the areas I find most beautiful. This past weekend, my mom came to Lander to spend some time with me and we hiked through Sinks Canyon, soaking up the sun and lounging in one of the falls. I’m truly going to miss this country and I look forward to coming back sometime in the future.
This past week, my field partner and I went on a five-day field tour throughout the Nevada Carson District in search of target plant populations to collect seed from. We scout for various target plant species common to the Great Basin within public lands that can then be used for research and restoration practices centering on improving native seed-based restoration. This week, our scouting brought us to the Pah Rah, Pine Nut, Carson, and Bald mountain ranges in search of late flowering/seeding forbs from our target species list. During this hitch, not only did we make four different seed collections, but I celebrated my twenty-third birthday.
On our first day, we traveled to the Pah Rah Range to look for a population of Machanthera canescens, Hoary Tansyaster, to determine its phenology and whether or not we will be able to make a seed collection from the population. We found our population in a flowering stage and determined we will have to revisit for potential seed collection on the next hitch!
We then traveled south to the Pine Nut Mountains to check on populations of Machantheracanescens. The road was a rock climb the entire ride up, but we found that it was the perfect time to collect seed from our population! We were able to make a sizeable collection of seeds that will be sent to Rocky Mountain Research Station (RMRS) to be used for common garden studies on native plant community restoration. We were also relieved to not have to travel on the rocky road again!
That night we camped on Mount Rose and traveled back to the Pine Nut Mountains in the morning to check on another population of Macanthera canescens. We were able to once again make a seed collection from our population to be sent for research at RMRS. After a morning of seed collection in the Pine Nut Mountains, we then traveled to the Carson Range near the California border and the Tahoe National Forest to check on populations of another one of our target species, Phacelia hastata or Silverleaf Phacelia. Upon checking on our Phacelia population, we realized the size and extent of our population was much larger than we initially thought. It was so large it required two days for seed collection! We were able to make a collection that can be used for both research purposes and for native seed-based restoration in the Great Basin! It was so exciting for us to be able to make our first restoration size collection from a plant species we have only been able to find in small populations throughout our district. This collection reminded us once again the importance of our positions. With every collection we make, we are working to progress and support native seed-based restoration within the Great Basin, which is under tremendous pressure from rising anthropogenic activity and global climate change. Within the past decade, the Great Basin has experienced increased frequency and intensity wildfires, with some summers burning over a million acres of rangeland. Currently, the Great Basin is challenged by increased fire occurrence and pressure on the landscape from cattle grazing and other anthropogenic activities. This has lead to a profound alteration in native plant diversity in some areas as invasives such as cheatgrass and western brome replace native sagebrush and perennial grass communities. By collecting native seeds to be used for restoration in post-burn sites within the Great Basin, we are working to disrupt the positive feedback loop created between noxious weed species and fire regimes in the Great Basin.
On top of having a seed collection win in Tahoe forest, we also found a campsite with a breath-taking view of Lake Tahoe. For dinner, we made a campfire and watched the sun set on Lake Tahoe from our campsite. As I reflected on the day, I thought to myself that there was no better way to spend my twenty-third birthday. I traveled throughout the most beautiful parts of Nevada to collect seeds that will be used for native seed-based restoration within the Great Basin to remediate the effects of wildfires. I am so grateful for this job and all the life lessons + adventures it comes with. Even more so, I am grateful to be working to conserve life and land in the beautiful Great Basin for future generations to enjoy just as much as I am.
Managing range lands can be difficult. As far as my job goes; it can be difficult to get close enough to cattle to identify brands and to get clear photos of them (each rancher has their own brand), constantly finding cows that are in the wrong pastures, a.k.a. out of compliance, can be frustrating and require a lot of paperwork. For my manager, and other full time range technicians, it can be tough to tell ranchers to move their cattle in a pleasant, but not overly passive tone. Being told what to do can be frustrating, and frankly some of the ranchers really don’t like the Bureau of Land Management, and frequently resist cooperation. I met a rancher who came out to help our crew find some past monitoring transects. He seemed agreeable enough, and was obviously kind enough to help out some BLM workers. But near the end of the day he made some comment about how the ranchers would do well at managing the land without the BLM telling them what to do. This might be true for some ranchers, but definitely not all. The data that my coworkers and I have gathered shows that overgrazing is currently occurring.
To give the ranchers the benefit of the doubt, it can be tough for them to keep track of all of their cattle while they roam thousands of acres of land, and moving the cattle seems like an ordeal that requires a significant number of people and resources. In addition to the inter-relational challenges of range land management, there are the effects of wildlife on the land. Cows are not the only animals grazing the public lands of south-central Wyoming. The presence of grazing wild animals can be a source of tension and ambiguity between ranchers and those monitoring the land. The BLM may attribute the degradation of the land to a lack of cooperation from ranchers and their cattle, while the ranchers claim that the impact of wildlife is to blame. Not all grazers play a role that directly competes with that of cattle. There is one animal that is of primary concern, that is horses. Namely, wild horses.
Horses feed in the same areas as cattle, and they share similar diets. One study suggests that the dietary overlap between horses and cattle during the summer averages 72 percent and in the winter increased to 84 percent (Krysl et al., 1984). And I would assume that since horses like riparian areas, their trampling of saturated, bare ground can have the same detrimental effects on stream banks as that of cattle. The population of wild horses is supposedly above carrying capacity, but there is no clear, ethical method to control them. Euthanasia can be viewed as inhumane, and thus, controversial, and rounding up horses and moving them to less populated areas is not enough. Adoption does seem to be a valid solution to controlling numbers of wild horses, but there is just not enough of it. Getting the word out to the public seems like a clear way to take a step in the right direction.
On a lighter note, the background of wild horses is pretty interesting. Horses are not really native to North America, at least not modern day horses. Horses were native to the continent but died-out after the last ice age. We can thank Spanish explorers and other European settlers for bringing the horse back to North America. But very few wild horses we see out west are descendants of those brought over by Cortez and Coronado. Most are descendants of horses that escaped from their owners only in the past 100-150 years. The term “wild” is not technically correct either. The horses are āferal,ā like an escaped house cat that has learned how to survive without human assistance (Crane et al., 1995). But “wild” sound better, it’s more romantic…I doubt the Rolling Stones would have had a hit with “Feral Horses”.
