Floristic Study of Swanton Pacific Ranch with Reed Kenny (Zoom talk)

Traversing Swanton: A multigenerational floristic study of the Cal Poly Swanton Pacific Ranch
A talk by Reed Kenny

Tuesday, June 6, 6:30 pm

The Swanton Pacific Ranch (SPR) is located north of the town of Davenport, in Santa Cruz County, California, and is owned by California Polytechnic State University, San Luis Obispo. SPR is approximately 1,295 ha and contains areas of salt marsh, coastal prairie, coastal bluff scrub, central coastal scrub, riparian forest, redwood forest, mixed evergreen forest, and chaparral. The property extends over an elevational gradient from 0 m to 420 m. In this study, we conducted a floristic inventory at SPR and documented 634 taxa. We vouchered 546 taxa with 974 specimens. We were unable to locate 64 taxa that had been previously reported, 28 represented from historic collections and 36 represented by personal observations but lacking vouchers. Overall, we documented 93 families at SPR, with Asteraceae, Poaceae, and Fabaceae having the most species, respectively. California rare taxa, listed by the California Native Plant Society, made up 2.5% of the flora. Locally rare taxa made up 10% of the flora (N = 66) Non-native taxa made up 26% of the flora (N = 169). We vouchered one new taxon for Santa Cruz County, Senecio aphanactis DC., which has a California Rare Plant Rank of 2B.2; documented a new occurrence of Hesperocyparis abramsiana (C.B. Wolf) Bartel var. abramsiana, a Federally Threatened conifer; and collected a form of Sanicula crassicaulis Poepp. ex DC that we have published as a new variety, Sanicula crassicaulis var. nudicaulis. Overall, this relatively small coastal ranch contains approximately 10% of the flora of California.
