Chess KA, Halvorson WL, Mceachern AK. 1996. San Nicolas Island Vegetation Monitoring Report, 1993-1996. Technical Report No. 56. U.S. Geological Survey, Cooperative Park Studies Unit, University of Arizona at Tucson. Tucson, AZ
During 1993-1996 vegetation monitoring was conducted on San Nicolas Islands of the California Channel Islands. Permanent point-intercept line transects were surveyed in the spring of each year (March to early May). Methods used on San Nicolas Island are identical to those used to monitor vegetation communities at Channel Islands National Park. This report presents the data and summarizes community trends for four years. Thirty-seven transects were sampled encompassing eight plant communities on San Nicolas Island. During 1993, the first year of transect sampling, 75 plant species were recorded on transects. The lowest number of total plant species encountered occurred in 1994 with 54 species recorded. In 1995, 62 species were observed on transects and in 1996 58 plant species were recorded. This report contains brief plant community descriptions and compares spring frequencies of important species surveyed during the four years.
