Garrison, California Department of Fish and Game, North Central Region 20070718 vector digital data http://bios.dfg.ca.gov ftp://ftp.dfg.ca.gov/BDB/GIS/BIOS/Public_Datasets/300_399/ds321.zip These data are the summary statistics calculated for trees and snags from the three 0.05-ha circular plot habitat samples taken in 2005 each at the 15 sample points at Spears and Didion Ranches, Placer County, California. There were three 0.05-ha circular habitat sampling plots at each of the 15 sample points. To be counted, trees had to be > 4" dbh and within the 12.6 m radius plot, while snags had to be > 4" dbh and > 9.8 ft tall and within the plot. 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. For more information on how this sampling component fits into the sampling scheme used on the Spears and Didion Ranch Parks project, see the the following documents: Garrison, B.A. May 2004.

It is assumed that these species were accurately identified, counted, measured, and summarized. 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). See the linked referenced protocols and data sheet in these metadata to evaluate the how the missing coordinates might affect any further analysis of these data Permanently joined extended table contents into shapefile. 20090702 California Department of Fish and Game Greg Ewing bios@dfg.ca.gov Vector Entity point 41 NAD 1983 California Teale Albers 34.0 40.5 -120.0 0.0 0.0 -4000000.0 coordinate pair 0.000000003754707655900803 0.000000003754707655900803 meter D North American 1983 GRS 1980 6378137.0 298.257222101 ds321 FID Internal feature number. ESRI Sequential unique whole numbers that are automatically generated. Shape Feature geometry. ESRI Coordinates defining the features. LATDD Latitude in decimal degrees using NAD83. LONDD Longitude in decimal degrees using NAD83. POINT_PLOT The sample point identification number followed by the vegetation plot identification number. NUM_TREES Number of live trees counted in the 0.05-ha circular plot. AVE_DBH_TR Average diameter at breast height (4.5 ft) of the live trees within the plot. NUM_HT_TRE Number of trees sampled in the plot for measurements of tree heights. AVE_HT_TRE Average height of the trees measured in the plots. QMD_TREE Average quadratic diameter at breast height (4.5 ft) of the number of trees within the plot. Quadratic diameter is calculated by dividing the (1) square of the sum of the squared diameters of the sample trees by (2) the total number of trees in the sample. TREES_AC The total number of trees per acre; this is calculated by multiplying the number of trees in the sample by 8.1 to expand the number to the number per acre. TREE_BA_AC Basal area (BA) (square feet of trees) per acre. This is calculated by summing the total cross-sectional area of the trees in the plot (square feet diameter) by 8.1 to expand the number to an acre. NUM_HWD Number of live hardwood trees counted in the 0.05-ha circular plot. The hardwoods are oaks and other trees with leaves. AVE_DBH_HW Average diameter at breast height (4.5 ft) (inches) of the hardwood trees within the plot. NUM_HT_HWD Number of hardwood trees sampled in the plot for measurements of tree heights. AVE_HT_HWD Average height (ft) of the hardwood trees measured in the plots. QMD_HWD Average quadratic diameter at breast height (4.5 ft) (inches) of the hardwood trees within the plot. Quadratic diameter is calculated by dividing the (1) square root of the sum of the squared diameters of the sample trees by (2) the total number of trees in the sample. HWD_AC The total number of hardwood trees per acre; this is calculated by multiplying the number of trees in the sample by 8.1 to expand the number to the number per acre.
