reference areas will be clearly indicated. Since the vegetation within each of the BRB's is of one plant
• community type, no separate map indication of plant community identity will be made.
SAMPLING DESIGN
• BRB -1. Twenty (20) sample points will be randomly placed within the boundaries of BRB -1.
• BRB -2 and 3. Twenty (20) and thirty (30) sample points, respectively, will be randomly placed
within each of BRB -2 and 3 The sampling points will be randomly located using an ArcView
script.
• BRB -4 and 5. These blocks will be sampled similar to BRB -3 in accordance with the
procedures described for BRB -3 and in the appropriate post revegetation years.
• Reference Areas. Thirty (30) sample points will also be randomly placed and numbered within
each reference area.

** Adequacy will be pursued beyond the stated sample size only if hypothesis testing using the "reverse

* ** Adequacy will be pursued beyond the stated sample size only if hypothesis testing using the "reverse

the "background" area standard and the "shrub concentration area" standard.
If possible, sample locations will be located in the field using pre - loaded GPS coordinates and
handheld field units.
COVER SAMPLING
Initial cover sampling will use the first fifteen (13) sample locations in reference areas and the first twenty (20) samples
in BRB areas. Where additional cover sampling is needed to achieve sample adequacy, additional samples of successively
higher number will be taken. Where more than thirty (30) cover samples are necessary, additional sets of five (3)
