Planning for the future: collecting seeds for sagebrush habitat restoration

This season we did one small collection for the Seeds of Success program! This collection was of Crepis acuminata (common name: Tapertip hawksbeard, Shoshone name: yham•bah•wuhrn), a small yellow flower in the family Asteraceae, tribe Chichorieae. It occurs in all western states from California, Oregon and Washington east to Montana, Wyoming, Colorado and New Mexico (USDANRCS, 2011).

These flowers are targeted in restoration efforts because they support wildlife including generalist bee species, sage grouse, elk, deer, and antelope. It is also utilized by livestock such as sheep and cattle! Based on seed transfer zone information and a previous scouting trip, we chose to gather seeds from about 3 hours from the field office, near the Duck Valley Indian Reservation and the border of Nevada, homeland to the Shoshone-Paiute tribes. Heading out there a couple days in a row resulted in a decent amount of driving time, but with some good music and podcasts, it went by pretty quickly! 

Important note: if you are choosing to travel/recreate during this time, try to do your research ahead and be respectful of indigenous territory and travel restrictions that tribes are implementing. Many reservations are being impacted particularly hard from COVID-19, and an influx of tourists/travelers can bring an increase in cases. 

Seed collecting is a very relaxing experience. I settled into a rhythm: find a plant, pick off the white tufts of seeds and feel them between my fingers to check for insect larvae, and then place them into the paper bag at my feet. repeat. It becomes almost meditative after a while. Our first day the heat was pretty intense so we didn’t stay more than an hour or so before heading back, but the following day was cooler and we were able to settle down and collect for a few hours. By the end of our second day we had a modest pile of white fluffy seeds, a promise of future little Crepis seedlings out scattered among the sagebrush.

By mid-august the Crepis acuminata was well over flowering and was getting very dry and crispy. My mentor Jessa often jokes that a lot of our work in the summer here requires getting good at necrobotany.
The plant community in the area we collected was primarily perennial grasses such as bluebunch wheatgrass (Pseudoroegneria spicata) surrounded with scattered sagebrush (Artemisia sp.),  and various forbs also associated with sagebrush communities.
Crepis flowers are quite cute! They have a white fluffy pappus that helps them disperse in the wind. Since we collected a little late, a lot of the heads had insect larvae damage inside (which is apparently common with Tapertip hawksbeard according to an observation way back in 1938 by Babcock and Stebbins), which made it more difficult to collect viable seeds but we still managed to do a small collection!
After two days of seed collection we treated the seeds with some no-pest strips and then packed those babies up and shipped them off to the Bend Seed Extractory in Oregon! They’ll be cleaned and used in future seeding projects. 

Until next time!
