This plot is intended to represent the "margin" of the vernal pool sampled in SNFN0371. Although this is the margin, vegetation like that represented in this relevé does not surround the entire pool. The plot is dominated by Navarretia leucocephala with scattered Deschampsia. The plot is located on a basalt plateau in the SW corner of the Hathaway Ranch.; There is a conservation on the property held by the Shasta Land Trust. The site is actively grazed by cattle.
