Milano, E.R., and Vandergast, A.G., 2018, Genotypes for six rare plant species found in San Diego County in 2016-2017: U.S. Geological Survey data release,


To understand the genetic structure of six rare plant species (Acanthomintha ilicifolia, Baccharis vanessae, Chloropyron maritimum ssp. maritimus, Deinandra conjugens, Dicranostegia orcuttiana, Monardella viminea), we obtained samples from known occurrences in San Diego County, prepared and sequenced ddRAD genomic libraries, and developed and analyzed a panel of genetic markers to assess population diversity and divergence. We provide this SNP genotype dataset in Structure format, produced in Stacks v2.0b8, for future monitoring efforts and population genetic analysis. These data support the following publication: Milano, E.R., and Vandergast, A.G., 2018, Population genomic surveys for six rare plant species in San Diego County, California: [...]

San Diego County has implemented a strategic management plan that identifies species, based on low numbers of occurrences or high risk of threat, for which management practices are recommended. This project aims to provide a reference point for the current status of genetic diversity of rare plant species that will inform future preservation and restoration efforts.
