Landsat data were classified with guided clustering techniques to inventory and map conifer species and general land cover on the McCloud Ranger District of the Shasta-Trinity National Forest in northeastern California. Four conifer timber types were differentiated. Two stocking and two size classes were also determined for each conifer type. Eighty-two percent of the ranger district is forested. Of the total forestland, 53 percent was identified as mixed conifer, 31 percent as ponderosa pine, 12 percent as mixed fir, and 4 percent as lodgepole pine. Accuracy of the classification was 83 percent when timber types, size, and stocking were being discriminated, and 88 percent when timber types were being identified without detailed breakdown to size and stocking. USDA Forest Service ground plot data were used to calculate timber volume and other stand values within Landsat categories. From these results, it was determined that Landsat analysis could provide timber type classifications for forest management planning.
