transact, the transact orientation was fumed 90° in the appropriate direction so the transact could be <br />completed. In this manner, boundary transacts were retained entirely within the target unit by <br />"bouncing" off the boundaries. Production quadrats were always oriented 90° to the right (clockwise) of <br />the ground cover transact and placed one meter from the starting point so as to avoid any trampled <br />vegetation. <br />23 Determination of Ground Cover <br />Ground cover at each sample point was determined utilizing the point-intercept methodology as <br />illustrated on Figure V-1. A5 indicated in this figure, Cedar Creek utilizes state-of-the-art instrumentation <br />it has pioneered to facilitate much more rapid and accurate collection of data. A transact of 10 meters <br />length was extended in the direction of the next sampling bcation from the flagged center of each <br />systematically boated sample point. At each one-meter interval along the transact; a "laser point bar" <br />was situated parallel to, and approximately 4.5 tb 5.0 feet vertically above the ground surface. A set of <br />10 readings was recorded as to hits on vegetation (by species), litter, rock (>2mm), or bare soil. Hitr <br />were determined at each meter interval by activating a battery of 10 bw-energy specialized lasers <br />situated along the bar at 10 centimeter intervals and recording the variable intercepted by each of the <br />vertically-projected, narrow (0.02' focused berms (see Figure V-1). In this manner, a total of 100 <br />intercepts per transact were recorded resulting in 1 percent cover per intercept This mettrodology and <br />instrumentation fadiitates the collection of the most unbiased, repeatable, and grease ground cover data <br />possible.

From within each quadrat, all above ground <br />current annual vegetation, excepting woody species, within the vertical boundaries of the frame were <br />dipped and bagged separately by life form as folbws: <br />Perennial Grass <br />Annual Grass <br />Perennial Forb <br />Annual /Biennial Forb <br />Noxrous Weeds <br />CwArt Cemr Assoca'rES, Inc Page 5 E>Qribit s -Bowie WRDA Vegefatlon Survey <br />
