The procedure for sample location within both baseline areas and reference areas occurred as <br />follows. First, a systematic grid was selected to provide approximately 20 coordinate intersections within <br />each community type, which could then be used for sample sites. For the Juniper Woodland baseline <br />area, this grid was 130 ft. x 130 ft.; for the old and new Juniper Woodland Reference Area the grid was <br />50 ft. x 50 ft.; for the Mountain Shrub baseline area the grid was 110 ft. x 110 ft.; and finally, for the <br />Mountain Shrub Reference Area the grid was 75 ft. x 75 ft. A systematic inter-grid (150 ft. X 100 ft.) was <br />used for 10 additional production points in the New Juniper Woodland Reference Area. Second, scaled, <br />computer generated representations of the selected grids were overlain on a computer generated map of <br />the area utilizing north-south and east-west compass points which could be easily established in the field. <br />This overlain grid also facilitated identification of the community type for each sample point (mapping <br />verification point). Third, utilizing a hand held surveying compass and hip-chain, GPS, or pacing <br />techniques, all sample points were located in the field. The locations of all sample sites used in 2006 <br />sampling efforts are indicated on Map E5-1. <br />Once a selected grid point was located in the field, ground cover sampling transects were always <br />oriented in the direction of the next site to be physically sampled to further limit any potential bias while <br />facilitating sampling efficiency. This orientation protocol follows that which is indicated on Figure A-1. " <br />• Depending on logistics, timing, and access points to the target sampling area, the field crew would <br />occasionally layout a set of points along coordinates in one direction and then sample them in reverse <br />order. However, orientation protocol was always maintained (i.e. in the direction of the next point to be <br />physically sampled). If the boundary of an area was encountered before reaching the full length of a <br />transect, the orientation of the transect was turned 90° in the appropriate direction so the transect could <br />be completed. In this manner, boundary transects 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 transect and placed one meter from the starting point so as to avoid any trampled <br />vegetation. <br />Determination of Ground Cover <br />Ground cover at each sample point was determined utilizing the point-intercept methodology as <br />illustrated on Figure A-1. As 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 transect of 10 meters <br />length was extended in the direction of the next sampling location from the flagged center of each <br />systematically located sample point. At each one-meter interval along the transect, a "laser point bar" <br />was situated parallel to, and approximately 4.5 to 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. Hits <br />e~~~ ~~~ ~~s®~~a~~ ANC.
