• inch = 700 ft Legend information on the boundaries of Bond Release Blocks (BBB's) and the <br />reference azeas will be clearly indicated. Since the vegetation within each of the BBB's is of one plant <br />community type, no separate map indication of plant community identity will be made. <br />SAMPLING DESIGN <br />• BRB-1. Twenty (20) sample points will be randomly placed within the boundaries of BRB-1. <br />• BRB-2 and 3. Twenty (20) and thirty (30} sample points, respectively, will be randomly placed <br />within each of BRB-2 and 3 The sampling points will be randomly located using an ArcView <br />script <br />• BRB-4 and 5. These blocks will be sampled similaz to BRB-3 in accordance with the <br />procedures described for BRB-3 and in the appropriate post revegetation years. <br />• Reference Areas. Thirty (30) sample points will also be randomly placed and numbered within <br />each reference azea. <br />Summary of Sampling Design <br />• <br />Action BRB-1 BRB-Z BRB_3 Reference <br /> Areas* <br />Quantitative Cover Max 20 20 samples 20 samples 15 samples each <br />Sam lin o ade ua and to ade ua and to ade ua <br />Quantitative 30 samples 30 samples 30 samples each <br />Production Max. 20 (No adequary) (and to adequary if (and to adequary if <br />Sam lin nec,** nec.** <br />Woody Plant <br />30 samples 50 samples <br />Density Sampling Max. 20 (No adequacy) (and to NA <br /> ade ua *** <br />Species Density 20 samples ~ 20 samples 15 samples each <br />SamPItT'S ~~ 20 (No adequacy) (and to adequary) (and to adequacy) <br />Success Narrative Narrative Hypoth.
