Barrett A. Garrison, California Department of Fish and Game, North Central Region 20070718 vector digital data https://wildlife.ca.gov/Data/BIOS https://filelib.wildlife.ca.gov/Public/BDB/GIS/BIOS/Public_Datasets/300_399/ds319.zip These data are the summary statistics calculated for components of the herbaceous layers, and shrubs and trees from the three 0.05-ha circular plot habitat samples each taken in 2005 at the 15 sample points at Spears and Didion Ranches, Placer County, California. These values are based on point intersections of live vegetation with a sighting tube at 25 points on eight 12.6 m transects through the 0.05-ha plot. Readings were taken in the center of each habitat sampling plot and at 4 m, 8 m, and 12 m on each of the eight transects within the plot. The transects are at 45 degree increments with one transect to the north. The herb layer is vegetation 0.5-2.0 m tall, while the tree layer vegetation is > 2.0 m tall. These data are intended to represent baseline data for wildlife communities and habitat conditions in these parks. They can be used to assess and monitor the park's ecological viability and sustainability.

Garrison 916 358 2945 bgarrison@dfg.ca.gov Version 6.2 (Build 9200) ; Esri ArcGIS 10.6.1.9270 It is assumed that the locations of the survey points are accurate with regard to the actual locations on the ground where the surveys were done. It is assumed that the species, position in canopy, layer constituent, and counts to determine cover were accurately made. Also, the spatial accuracy of the 100-m count circle radius is presumably accurate to +- 5 m because boundaries were measured with laser rangefinders and marked in the field with flagging. All vegetation-habitat sampling occurred at 3-circular plots around each of the 15 sample points in the project area. During data compilation the coordinates of the centers of 4-plots (3-2, 11-3, 12-3, and 14-1) were lost and are not shown when this data layer is displayed. However, the attribute data for these points exist in the database and are available for analysis if the exact point is not required (Contact the Data Distributor).

UNDER Understory trees are perpetually shaded and below the overstory trees OVER Overstory trees receive perpetual sunlight and are above the understory trees MID Midcanopy trees are partially shaded and are below the overstory trees and above the understory trees. SPECIES Name of vegetation component intersecting view through the sighting tube. Full species have common names, while other are categorized. FORBS are herbaceous vegetation, and GRASS are usually graminoids. SCI_NAME Scientific name of plants. Some plants are only classified to genus. They are identified by "sp." following the genus name. VEG_HITS Total number of hits with sighting tube for a maximum of 25 readings taken from the 8 transects. PROP_COVER The proportion of hits of the indicated species or vegetation componets divided by 25 (the total possible number of hits within the 0.05-ha plot. POINT_PLOT The sample point identification number followed by the vegetation plot identification number. This data set contains information on what constitutes the canopy, and the canopy's location and amount of cover. 20231027 Biogeographic Data Branch, California Department of Fish and Game Gordon Gould mailing
