5. A random number generator will be used to select the coordinates for each <br />sample site. If the coordinate falls outside of the sampling area, a new <br />coordinate will be generated. Reclamation Area 41 will have 50 random <br />coordinate intersections and the reference area will have 30 (Figure 2). <br />Transact Location <br />Each 50 meter transect will start at a given coordinate intersection and travel in a <br />randomly generated compass direction. In Area 41, transect direction will be <br />randomly selected from one of 4 compass points to cross the shrub strips at 45 <br />degrees. In the reference azea, transect direction will be randomly selected from one <br />of 8 compass points, N, NE, E, SE, S, SW, W and NE (Figure 2). <br />Ground Cover <br />Ground cover will be collected at five-meter intervals along each 50 meter transect. <br />Ground cover at each sample point will be determined using the point-intercept <br />methodology utilizing a 1 meter `9aser point bar" as illustrated on Figure 1. This <br />methodology is identical to a standazd `din-type" 10-point frame. However, the use <br />of the "laser point bar" facilitates the collection of the most unbiased, repeatable <br />and precise ground cover data possible. <br />At each ve-meter interval, a laser 10-point frame will be set perpendicular to the <br />transect. The `9aser point bar" will be situated horizontally above the ground <br />surface and a set of 10 readings recorded as to hits on vegetation (by species), litter, <br />rock or bare soil. Beam angle will be set at an angle previously established by <br />TMCC. Hits will be determined at each meter interval by activating a series of 10 <br />low-energy (0.5mW), 635nM-wavelength lasers situated along the bar at 10 <br />centimeter intervals and recording the variable intercepted by each of the narrow <br />(0.020' focused beams (Figure 1). In this manner, a total of 100 intercepts per <br />transect will be recorded resulting in 1 percent cover per point intercept. <br />page Z <br />Habitat Management, Inc. June 16, 1998 <br />
