2.4 QUANTITATIVE SAMPLE MEASUREMENTS <br />2.4.1 Cover <br />Cover was measured by point intercept techniques at 1 meter intervals <br />along a randomly oriented 50 meter transect. At each point a metal pin was <br />projected downward from a height of 4 feet perpendicular to the transect and <br />first hits on vegetation, litter, rock, or bare ground were recorded. <br />Additional hits on vegetation were recorded by species to provide a more <br />complete description of the species composition within each community. <br />2.4.2 Production <br />Herbaceous production was obtained at each random sample site by <br />harvesting the above ground herbaceous growth in a 1 x 1 meter square <br />quadrat. Harvested tissue was separated by major species white minor species <br />were combined by lifeform group. Leguminous perennial fork species were <br />separated from other perennial forb species. Species with an estimated dry <br /> <br />weight less than 1 gram were noted as a "trace" and arbitrarily assigned a <br />value of 0.3 grams in data calculations. Harvested tissue was placed in <br />paper bags, oven dried at 105° C for 24 hours and weighed to the nearest 0.1 <br />gram. <br />2.4.3 Density <br />Shrub density was obtained along a randomly oriented 50 meter transect by <br />counting all individuals rooted within 0.5 meter of both sides of the <br />transect (i.e. within a 1 x 50 meter quadrat ). Shrub seedlings less than 5 <br />inches tall were not counted; however, adult shrubs possessing diminutive <br />morphology were counted. <br />Tree density was obtained along a randomly oriented 50 meter transect by <br />counting all individuals rooted within 1 meter of both sides of the transect <br />5 <br />Exhibit ]0, Item 5 Revision Date: 03/06/07 <br />]0 RevisionNo.: PR-02 <br />
