Lately we’ve been spending a good deal of our time thinking about the rain. Northwest New Mexico is currently experiencing what the USDA calls “extreme drought” (for more information about current drought conditions across the U.S. visit this website) and everyone here is holding their breath to see what this monsoon season will bring. Areas outside of Farmington are definitely getting some rain; we can see thunderstorms in the distance and some of our field sites are currently inaccessible due to flash flood conditions from rain that fell in the La Plata Mountains and elsewhere. For now, though, the plants in our district are still very, very thirsty.
Despite the drought, we have been able to make several collections from some very hardy plants. Last week we made a robust collection of Hetrotheca villosa (false hairy goldenaster) from a population that is holding on to life in a dry wash. This species is especially fun to collect because the mature seed heads are similar to dandelions and are most easily collected using a handheld Dustbuster vacuum.

We also made our second collection of evening primroses for Dr. Krissa Skogen’s research on the Onagraceae family (more information about her research can be found here). We found a population of Oenothera pallida ssp. runcinata (pale evening primrose) along a shallow wash a few weeks ago, when the water was barely running. When we returned earlier this week, we could see that the floodwaters had risen dramatically and an area that had previously been dry land was covered in about two feet of water before receding again. Despite being caught in the flood, the little Oenothera were still hanging on! We really enjoy the opportunity to contribute to Dr. Skogen’s research and hope to spot more Onagraceae species.

One thing we learned is that this is the season for baby horned lizards (also called horny toads). We’re really excited about this because most lizards are too fast too catch, but horned lizards are so pudgy that they are easy to scoop up as they waddle along. So far, we’ve caught several babies as well as a full-grown adult. The adult is about the size of my palm, while some of the smallest young lizards are smaller than my thumbnail. Finding horned lizards is considered good luck by the Navajo, so we’re hoping that it’s a good omen that we’ve been encountering so many.

We recently had the privilege to meet Dr. Richard Lee, one of the authors of the book Weeds of the West. Unbeknownst to us, Dr. Lee teaches a short course on invasive plants in Farmington every summer. It turns out that we live in a veritable invasive plant mecca! He came into town with a truck full of invasive plants that we stored in my cubicle and he was kind enough to invite us on his guided tour of invasive plants in the area. It was very useful to learn more about invasive plant species and definitely helped me learn what to look out for in the field.
My cubicle turned into a junge of a wide variety of invasive thistles, knapweeds and others for the day.
We hope to be very busy in a few weeks after we (hopefully) have some good rain and the plants perk up. In the meantime, do a rain dance for us!
