On The Lookout for LODI

Hey blog! Since my last entry Sahalie and I have been all over Washington, Oregon, and Idaho. The scouting season has begun! Our target species to scout for at the moment are Sphaeralcea (Globemallow) and Lomatium dissectum (Fernleaf Biscuitroot/LODI). We quickly learned it was too early for the Globemallow to be flowering, making them quite difficult to scout for without their bright orange inflorescence. The last few weeks we have focused on looking for LODI populations to collect seed from later on. 

The scouting process

The scouting process begins long before we hit the road. We usually spend a day examining topographic maps, and satellite imagery for the regions we want to visit, along with a thorough search of herbarium databases to see specific locations LODI has been found in the past. All of these resources help us narrow down a few places we think we will be most likely to find LODI. For this species we are looking on the maps for steep eroding rocky canyons with north and west facing slopes. However throughout the last few weeks we’ve learned quite a bit more about LODI’s habitat preference that doesn’t always follow this pattern! It seems that LODI likes to have an adjacent hill or wall to shade the slope they are growing on. We have also found it thriving on south facing slopes and in little gullies coming off of mountain drainages. After finding LODI on the steepest eroding slopes it was surprising to find it in the much more subtle topography changes of these shallow gullies filled with tumbleweeds. 

On the ground

Once we arrive at the places we’ve circled on the maps, the real scouting begins. Sometimes we get lucky and find a huge population instantly, you can even spot it from the road. Other times we will spend the entire day barely scraping up a population of 200 plants. 200 plants is the minimum number of plants we need in a population in order to collect seed from it. Over the last few weeks we have found populations that range from thousands of plants, hundreds of plants to just over 200. Once we have established that our population has enough plants we will begin to map it. This entails walking through the population dropping waypoints approximately every 30 meters and giving an estimate for about how many plants surround each waypoint. By the end of this process we will have a point cloud of the population that gives us a sense of both the boundaries and how many individuals it contains. This information is super helpful for whoever has to find the plants again to collect seed in the future. As we map we also collect leaf tissue samples. For each population we will select 12 plants to collect tissue from, scattered evenly throughout the area. Finally, we will take photos for each population. Each photoset includes the plant’s inflorescence, leaves, stems, base, involucres, the whole plant, the plant in its habitat, and a landscape photo of the habitat from outside of the population.

I have absolutely loved this month of scouting. It’s such a good feeling to pick out a little point on the map of somewhere you’ve never been, and then to go there, see the landscape in person, and find exactly the plant you’re looking for! It has taken us to some absolutely magical and remote places and I cannot wait to see more of the Great Basin as the season continues!

Our crew has grown a lot this last month with several new Forest Service technicians joining the team. We have all become such good friends! Outside of work we have been climbing, camping, and having beach days by Lucky Peak reservoir. I’m feeling so lucky to have such a good crew and group of friends to adventure with out here! Here are few more pictures of what we have been up to.

Seeds, Surveys, and More Seeds

Hi CLM blog!

My name is Alaina and I am one of the new interns working with the U.S. Forest Service at the Rocky Mountain Research Station in Boise, ID. It’s hard to believe we are already wrapping up the first month of our internship. Just a few weeks ago I was driving away from a gray and snowy midwest winter in Michigan and into the mountains out west. It feels so good to be back out in these wide open spaces and have spring with finally beginning! Just in the last week or two we have been watching the landscape begin to green up for what people call the “green week” here. The only time of the year these mountains may green.  

The research project we will be assisting here centers around using native seeds in restoration and aims to show how locally adapted plant populations may be better suited for restoration in their respective ecosystems, compared to more generalized seed mixes. This summer we will be monitoring these plant populations at our common garden sites and collecting seeds all over the Great Basin and Snake River Basin. So far we have been spending our time getting acquainted with cleaning and counting thousands of tiny seeds and surveying plants at the Orchard, ID and Richfield, ID common gardens.

As we arrived to the Orchard common garden for the first time this season we were met with a garden teeming with life! Unfortunately, it was not the plant life we wanted, but rather lots and lots of weeds. In true gardening fashion the first big step of getting common garden surveys rolling was weeding. Slowly the first sprouts of Erigeron pumilus (ERPU) and Phacelia hastata (PHHA) were revealed. After freeing each plant of its surrounding weeds we finally began surveying. For each plant we survey, we assign it a phenophase that describes which point of growth it is at for the season. Currently most of the plants are currently between a 1 and 3.5, 1 being just the beginning of growth and 3.5 meaning the plants are already budding! If the plants are at least at a phenophase of 2 we will go ahead and collect the largest leaf, and measure the diameter of the rosette.

When we aren’t out in the field we usually spend our days processing seeds in the lab. Trying to differentiate between tiny seeds and the other reproductive parts of the plant they are combined with has been quite the test on my vision. One of these processes involves taking apart dried flower heads sampled from the gardens in 2021. For each flower head we will sort the seeds from the chaff (other parts of the plant) and count how many seeds it contains. It is amazing how a flower the size of my thumbnail can have over 300 seeds! This has given me a whole new perspective and appreciation for these little plants. The other process of seed cleaning has been de-winging seeds or as I like to say, removing the “fluff”. Once de-winged we will put the seeds into an air column to separate the seeds from the “fluff” by their difference in weight. The result? Thousands of cleaned and counted seeds ready for use.

Outside of work Sahalie and I have been settling in and sprucing up our little trailer. We have made it quite the home and are getting used to the more “off grid” living. The beautiful hills and cliffs along Lucky Peak Reservoir are basically our backyard, and we can watch helicopters land at the Forest Service helipad from our kitchen window. We have explored several local hikes and even some hot springs to make use of the last cold weekends before summer. Additionally, we’ve been exploring the city, trying new food, attending the Treefort Music Festival, and spending a lot of time along the Boise Greenbelt. Living out in our trailer in the foothills while also working right in downtown Boise in our office has been such a unique blend of city and outdoor life. As the weather continues to warm up we are gearing up for so many more adventures around Idaho, Oregon, Nevada, and Utah and can’t wait to see all the places that seed collecting will take us later this summer!
