Table 3 Land cover types found on the five wine grape-growing ranches in Mendocino County, California, considered in this study

From: Assessment of carbon in woody plants and soil across a vineyard-woodland landscape

Number of Vegetation Plots Number of Soil Pits Habitat Type Elevation (meters) Slope (degrees) Solar Radiation (W-hr/m2/yr)
0 19 Vineyard I 173 0.7 2.18*106
0 6 Vineyard II 572 10.7 1.99*106
0 2 Annual Grassland 213 5.0 2.27*106
17 1 Valley Riparian 152 0.4 2.18*106
39 2 Mixed Hardwoods I 534 21.3 1.97*106
26 13 Mixed Hardwoods II 225 10.7 2.16*106
11 1 Mixed Conifer-Hardwood 407 25.8 2.06*106
  1. The classification process consisted of a partitioning around mediod (PAM) analysis, which used 1013 random points and binned them into similar groups based on four variables: land cover; elevation; slope; and solar radiation (see methods).
