Research - San Juan 2005


San Juans Survey 2005

In spring 2005, we conducted two trips (April 25-27; May 28-30) during which we visited a total of 27 islands. We focused our activities off of the south end of Lopez Island, visiting parcels as far east as Lopez Pass and as far west as Deadman’s Island. We collected approximately 1,700 specimens (900+ vascular plants; 500+ bryophytes; 300+ lichens) totaling more than 400 taxa. We identified 20 new localities for five state-listed vascular plant taxa, and located the first U.S. population of a previously undescribed taxon of Castilleja ambiguaHook. & Arn. (Indian paintbrush). Results from the 2005 surveys are currently being written up for publication in a regional research journal.

Summary statistics for the vascular plant data from the 2005 field season are summarized below. 

 

Number of participants in the field 28
Number of islands, islets, and rocks visited 27
Total specimens collected 924
Number of taxa (species, subspecies, varieties collected 198
Number of additional taxa observed but not collected 45
Total number of taxa collected or observed 243
Percentage of native taxa 70%
Range of native taxa found on all islands 44-100%
Size range of islands, islets, and rocks visited 0.5-43 acres
Number of new localities for state-listed taxa 20

Administrative, permitting, technical, field, financial, and transportation support for this project was provided by U.S. Fish and Wildlife Service, Washington State Parks and Recreation, National Park Service, U.S. Forest Service, Washington Natural Heritage Program, The Nature Conservancy, The Snow Goose, Bureau of Land Management, Washington Native Plant Society, and the University of Washington Herbarium (Burke Museum of Natural History and Culture).
