This is the 1994 USFS Landsat vegetation and tree size map for the Walker Creek sub-basin. Most of the northern and western
basin extending Toward Tomales Bay is grasslands and pasture, which show as Non-Forest in this theme. Forests cover the
hillslopes in the southern and eastern parts of the Walker Creek basin as higher relief brings higher rainfall, which makes forests
thrive. Forests may also grow more vigorously in draws and on north facing slopes. The vegetation classification is accurate at a
one-hectare scale (approximately 11 pixels) and is suitable for stand classification. Data provided by the U.S. Forest Service
Spatial Analysis Lab in Sacramento, CA. Scale = 1:177,828 .
