Physical Environment Meeks Table is an isolated, flat-topped butte rising 150 m above the surrounding rolling terrain (fig. 1). It is a remnant of a larger. Figure 1.—Meeks Table Research Natural Area - a 27-ha isolated, basalt-capped plateau. plateau isolated by river action. Elevation on the table varies from 1 280 to 1 585 m. Access is by a steep, narrow trail up the knife- like ridge at the northwest end. A modified continental climate prevails. Most precipitation occurs as snow during the cool, cloudy winter. Summers are warm, generally low in precipitation, and largely cloudless. One to 3 months of drought are common. United States Weather Bureau (1965) climatic data from Bumping Lake located at 1 400-m eleva- tion in a valley 16 km west of Meeks Table are as follows: Mean annual temperature °C Mean January temperature °C Mean July temperature °C Mean January minimum °C Mean July maximum temperature °C Average annual 1 214. mm July through August 69. mm Average annual snowfall 554. cm Methods In July 1968 vegetative cover and composition were sampled on 48 plots spaced at 50-m intervals from a random start along four lines traversing the table from northwest to southeast. Cover and compostion of herbaceous and shrubby vegetation were measured with a 100-pin point frame 60 x 60 cm (Brown 1954). Using the center of the point frame as a plot center, cover of tree overstory was measured with a spher- ical densiometer. Height of the tallest tree and diameter at breast height of all trees on a circular plot was recorded by species. Soil cores and loose soil samples were collected on every third plot to a depth of cm at the plot center. Chemical an
