Working in collaboration with the USFS, on October 5th， 2020年，IAE工作人员从 Erigeron subglaber (Pecos fleabane) at the top of Elk Mountain, 在佩科斯荒野的USFS陆地上. In spring 2020, Maria Mullins (Southwest Seed Partnership Coordinator) and Melanie Gisler (SW Director) met with Kathryn Kennedy (USFS Region 3 Botanist) to prioritize rare plant species for seed banking. 接下来，IAE工作人员与Bob进行了协调 Sivinski (RCS Consulting & 前新墨西哥州植物学家), who supplied information regarding species phenology, 种子成熟时间, and locations of populations with potential to yield CPC quantities needed. In late summer, Bob and Maria traveled 3 hours (in separate vehicles due to COVID) on rugged roads to scout the Pecos fleabane population and check phenology. A few weeks later, Maria returned to the site to check phenology, but the seed was not mature yet. Because this is a drought year in the Southwest, 许多植物没有结出种子, and staff were concerned that many plants would abort their seed set without additional late season moisture. On October 5th, Maria returned to the site with IAE Ecologist, Yvonne Hickerson to make the seed collection. They found enough plants with viable seed and proceeded to collect from 74 maternal lines and 15 tissue samples. 在处理过程中, Maria and Yvonne estimated that 40% of the seed was viable likely due to drought stress. 种子又小又轻 they 还得计算种子的数量 all of 母系是因为 their 磅秤没有记录重量.
