A few scattered ponderosa pine (Pimis ponderosa) were present. Annual precipitation averaged between 12 and 14 inches, much of it as snow. The soil, a sandy loam of basalt origin, was classified in the Underwood soil series (Gardner, 1956). This was a good bitterbrush site and it probably could support as many browse plants as any deer winter range likely to be seeded. Maximum stocking for drier, more difficult sites is likely to be lower. A drought in 1959 may have caused mortality to show up earlier than it would have otherwise. EXPERIMENTAL METHODS Each of the 588 bitterbrush plants was located on a large-scale map of the plot. At the time of mapping we measured the total height and two diameters of each plant and classified its condition as follows: 20-40 precent E in 60 percenl V 60 sii percenl G 80 99 percent X 100 percenl From the map, LOO plants were randomly selected. Each planl was con- sidered as a pint center and the following measurements made to characterize plant compel ii ion : .i. Number "f plants in :i 3-fool circle, b. Number of plants in :i 5-foot circle. <•.
