Summary
The condition of bees is Unknown.
Bees were identified as an important data gap in the original 2016 Peak Health effort, which led One Tam partner agencies to begin bee studies in several locations in Marin County in 2017. Preliminary data from these surveys were used to develop metrics for the 2022 update. While it is too soon to be able to assess the condition or trend of these metrics, early signs are promising: 29% of known species and 84% of known genera were detected, and the median species richness at all sites was 36 (a remarkable recapture rate, given study limitations). In addition, 28% of known specialist species and 10 new specialist species were detected, including several that are rare or uncommon. These findings indicate that there are healthy populations of specialist host plants and suitable nesting habitat in the study area.
