The sea-cliff bedstraw (Galium buxifolium) data set contains two types of information, formatted as CSVs: 1) Spatial coordinates (WGS 84) of known population occurrences on Santa Cruz and San Miguel Islands, California, as of 2006 (sensitive locality information); 2) Demographic data measured at four populations growing on Santa Cruz Island. Three of the populations were measured in 2005 and 2006, the fourth was measured in 2005, 2006, 2008, 2010, 2011, and 2014. These data support the following publication: McEachern, K., Chess, K.A., Flagg, K., and Niessen, K.G., 2019, Sea-cliff bedstraw (Galium buxifolium) patterns and trends, 2005–14, on Santa Cruz and San Miguel Islands, Channel Islands National Park, California:...

The Rare Plant Occurrences geodatabase is an element occurrence data system with about 10,000 records of rare plant observations on the 6 northernmost California Channel Islands. It is a live database created with the purpose of bringing together in one space all discoverable historic and current information on the localities of about 180 rare and sensitive plants of the northern Channel Islands, California. The list of taxa was developed from agency databases, supplemented with a 1-day workshop with area botanists in 1993; the list has been updated as new information emerges. Data records range from the late 1880s to 2019, including information from herbarium labels, published and unpublished literature, agency...
