Environmental Science Associates 20070701 1st edition vector digital data BIOS California Department of Fish and Game ftp://ftp.dfg.ca.gov/BDB/GIS/BIOS/Public_Datasets/200_299/ds295.zip http://bios.dfg.ca.gov This layer contains polygon data for the perennial pepperweed (Lepidium latifolium) database. This database represents distribution data collected within the areas surveyed throughout the San Francisco Bay, San Pablo Bay and Suisun Bay in California between July, 2004 and June, 2007. Perennial pepperweed is a non-native invasive plant that is currently invading wetland, riparian and cultivated areas throughout California. Within the areas surveyed, all patches larger than 1 sq m of pepperweed were recorded using a Trimble geoexplorer III. This shapefile does not represent a complete distribution of Lepidium latifolium within the San Francisco Estuary. It does represent a complete distribution, as of the date surveyed, for the targeted areas as outlined in a separate shapefile, "Perennial Pepperweed Survey Areas - San Francisco Estuary [ds412]". The database contains distribution data for pepperweed (Lepidium latifolium) for individuals to view and to produce maps to assist in monitoring, eradicating and controlling this species. Spatial Data Capture Methods: Field and spatial data were collected by professional biologists. All of the spatial data were recorded using global positioning systems. Some patches that were visible but inaccessible were captured initially using a reference point, then drawn as polygons using aerial photos. Assessment of patch characteristics are preliminary and may contain errors and/or inconsistencies. Changes in data collection techniques in late 2004 mean that not all of the characteristics were collected for patches recorded in 2004. Species found within or immediately adjacent to patches were only reliably identified to genus. Many patches occurred within the marsh/upland or marsh/ruderal transition zone. The habitat recorded for these patches was a reflection of where the majority of the patch was and the dominant species present. 20040701 20070601 Data collected 2004-2007 Complete As needed -122.544959 -121.944380 38.130742 37.407749 None weed pepperweed invasive Lepidium latifolium ISO 19115 Topic Category farming environment biota None Don Edwards Wildlife Refuge California San Francisco Estuary San Francisco Bay None If the data is used in a professional document or published, then Environmental Science Associates should be cited as the authors of the data.

PDOP is a measure of the geometrical strength of the GPS satellite configuration. PDOP shows the amount of error in your position. A PDOP less than 4 gives the best accuracy (under 1 meter). Between 4 and 8 gives acceptable accuracy. Greater than 8 gives poor accuracy. 20160229 Environmental Science Associates Melanie Vanderhoof Biologist mailing and physical
