Demographic data and location information for the endangered Gailum buxifolium from 2005 to 2014 on Santa Cruz and San Miguel Islands, California 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:...

It was used in the analysis for the Manuspcript "Long-term impacts of exotic grazer removal on native shrub recovery, Santa Cruz Island, California". These sites were sampled in 2004 and 2016 to gain a longer term view on native shrub reestablishment into exotic grasslands after exotic grazer removal.

It was used in the analysis for the Manuspcript "Long-term impacts of exotic grazer removal on native shrub recovery, Santa Cruz Island, California". These same transects were sampled in 2004 and 2016 to gain a longer term view on native shrub reestablishment into exotic grasslands after exotic grazer removal.
