III. Comments - Compliance
Below are comments on the inspection. The comments include discussion of
observations made during the inspection. Comments also describe any
enforcement actions taken during the inspection and the facts or evidence
supporting the enforcement action.
WOODY PLANT DENSITY
A MORE MEANINGFDL EVALDATION OF THE WOODY DENSITY DATA IS MADE BY COMPARING
SPECIFIC RECLAMATION AREAS WHICH WERE SAMPLID BY CYCC IN 1991, WITH THE 1992
NLRD DATA FOH THOSE SAME AREAS, AS SHOWN BELOW.
CYCC, 1991
MLRD, 1992
13.5 AC. (10/81)
II = 283 +_ 75
N = 30
Nm = 199
21.6 AC. (10/82)
II = 1,578 + 469
N = 30
Nm = 257
13.5 AC. (10/81)
D= 133+22
N = 4
Nm = 11
10.8 AC.
WEST 1/2 (10/82)
D = 1701 + 44
N = 2
Nm = 1
10.8 AC.
EAST 1/2 (10/82)
II = 801.5 _+ 312.5
N = 2
Nm = 30
25.7 AC. (10/80)
D = 1,133 _+ 133
N = 58
Nm = 77
25.7 AC. (10/80)
D = 1,332 _+ 1,293
N = 3
Nm = 282
FOR THE AREAS COMPARID, THE TOAL REQOIRID SAMPLE SIZE, WHEN STRATIFIID BY
AREA. AS INDICATED IS Nm = 533 FOR THE CYCC DATA, AND Nm = 324 FOR THE MLBD
DATA. DRAMATIC Nm RIDIICTIONS ABE SEEN FOR THE MLID DATA AS COMPARID TO THE
CYCC DATA FOR THE 13.5 AC. (10/81) AREA (199 VS. 11) AND THE 21.6 AC. (10/82)
AREA (257 VS. 31). THESE RESIILTS ARE LILLY ATTRIBDTBLE TO LONGER TRANSECTS,
AND WITN RESPECT TO THE 21.6 AC. (10/82) AREA, A FDRTHER LEVEL OF STRATIFICATION.
CYCC TRANSECTS WERE 50 METEBS IN LENGTH, WHILE MLID TRANSECTS WERE OF VARIABLE
LENGTH, BOT AVERAGID 368 METERS. POR SAMPLING PORPOSES, THE DIVISION
STRATIFIID THE 21.6 AC. (10/82) AREA INTO TWO UNITS, AN EAST FACING SLOPE AND A
WEST FACING SLOPE. THE EAST FACING SLOPE WAS CBARACTERIZID BY A MOCH HIGHER
VEGETATION COVER AND ffiIBITID A RELATIVELY DNIFOBM WOODY PLANT DISTRIBDTION.
THE WEST FACING SLOPE HAD A LOWER COVER AND WOODY PLANTS WERE CONCENTRATED IN
A RELATIVELY SMALL AREA IN THE SOOTHERN.PORTION OF THE PARCEL. LONGER TRANSECTS
AND FORTBER STRATIFICATION RESIILTID IN DECREASID VARIATION AMONG SAMPLES,
WITHIN EACH SAMPLING OMIT.
