Field data for the Vegetation Mapping Inventory Project of Point Reyes National Seashore, Golden Gate National Recreation Area [and Muir Woods National Monument]
1997-2011. Field data for the Vegetation Mapping Inventory Project of Point Reyes National Seashore, Golden Gate National Recreation Area [and Muir Woods National Monument]
This reference is an assemblage of field data collected as part the baseline vegetation inventory for the park unit. Typical files here are vegetation plot data, accuracy assessment data, field photos, PDF showing locations of vegetation plots and accuracy assessment data, and other data for this type. Plots were placed subjectively by the crews by selecting a representative portion of the polygon (selected by the photo interpretation and vegetation classification teams). Plots were of variable size (generally 400m2 for scrub and herbaceous vegetation and 1000m2 for forests and woodlands) and shape. When canopy conditions permitted, the plot’s location was recorded with GPS. Plots were not permanently marked. Plot sizes were set at 1000 m2 for forests and woodlands and 400 m2 for shrublands and herbaceous vegetation. The plots dimensions were variable. When possible, plots were placed subjectively in the most representative part of each stand of vegetation. Cover and height were estimated for each stratum (herbaceous, shrub, and tree). Cover of dominant life form was also estimated. All the species of each stratum were listed and percent cover was estimated.
