'-• area. These areas have been combined in this report for <br />~, <br />purposes of analysis and characterization of the vegetation <br />types present. <br />I-2.2.2 Sample Point Location <br />The reference areas (referred to as control areas in <br />tables) and the study areas were randomly sampled by laying <br />out two perpendicular lines, one along the south edge of <br />each study area (x axis) and one along the west edge (y sais). <br />- On the study areas, starting point locations for randomly <br />locating sampling points for density, production and cover <br />quadrats were initially determined in the office prior to <br />field work by establishing a grid with x and y axes, each <br />• containing 99 units. IInit size for each axis was determined <br />by study area width aad length. Numbers were taken from a <br />table of random numbers with 99 as the greatest possible <br />number. The starting points for initiating randomization <br />were then marked on a map. Random numbers were generated <br />until sufficient points were obtained for each vegetation <br />type within each study area. These points were then located <br />as close as possible in the field and a second set of two <br />2-digit numbers was taken from a table of random numbers <br />to determine sample point location. The field operator then <br />paced the number indicated by the first random number in <br />a predetermined direction. North was used unless pacing <br />...~~ <br />-4- <br />
