The Yuma Chapter has a great new meeting location at the Arizona Game and Fish Department (AGFD) Region IV Office, 9140 E. 28 Street in Yuma. AGFD recently expanded their conference room, providing us with a beautiful, efficient meeting space. It is conveniently located between the foothills and the city proper, making meetings more accessible to our far-flung members. We meet at 7:00 p.m. on the 3rd Thursday of each month; field trips are held on the following Saturdays.
All field trips leave from the Love’s gas station parking lot at the corner of Gila Ridge Rd. and 3E (just east of the BLM parking lot). Trips leave at 8:30 am unless otherwise stated.
For Yuma Chapter information contact Valerie Morrill. Watch for meeting announcements in the Yuma Daily Sun “What’s Going On” column.

Cactus Moth Detection Monitoring
We recently completed our second year of cactus moth detection monitoring in collaboration with U.S. Department of Agriculture Plant Health Inspection Service (APHIS) and the Yuma Conservation Garden. No results from the data yet, but we were fortunate that no cactus moths were detected in Yuma or elsewhere in the state in last season’s survey.
Asclepias subulata Salvage Project The Yuma Chapter is coordinating with other partners—primarily Arizona Western College, Bureau of Land
Management in Yuma, the Yuma Conservation Garden, and local Girl Scout troops—on a salvage project for Asclepias subulata (rush milkweed, ajamete), grown for seed at the college. Upward of 600 plants will be transplanted into restoration sites and educational displays.
Field Notes from the Yuma Chapter 2019-2020 Season Arizona Native Plant Society “Plant Families from Asteraceae to Zygophyllaceae”
Posted on Mar 27, 2020
Members of the Yuma Chapter are devoting meeting time to the study of plant families represented in the Sonoran Desert flora of our area. Asteraceae, the first family we studied, was presented remotely in December via YouTube by chapter president Valerie Morrill. In February, Erv Barnes followed with a discussion on the puzzling Zygophyllaceae. Later that month a group trekked to the Imperial Sand Dunes in California to find examples of both plant families, spring wildflowers, and to inspect an unusual growth form of creosote bush, Larrea tridentata. We stopped at two places off I-8. The first stop south of Sidewinder Road exit and the second was at the historical Old Plank Road ACEC on BLM west of the Grays Well exit.
