Principle Findings
The principle findinqs
from the 1999 Monterey Bay National Marine
Sanctuary kelp resource inventory were summarized,
by CDF&G kelp bed numbers, as follows: 1) Summary of the 1999 Sanctuary-wide Kelp
Resource Extent The total 1999 surface kelP canopY resource,
within the MBNMS (CDF&G kelp beds 208-225),
occupied canoPylplanimeter areas of 14.053 sq. mi.
and 22.358 sq. mi., respectively. The relative
densitv index was measured at .63. 2) Summary of the 1989 Sanctuary-wide Kelp
Resource Extent The total 1989 surface kelP canoPy resource,
within the MBNMS (CDF~G kelp beds 208-225),
occupied canopy/planimeter areas of 16.918 sq. mi.
and 25.814 sq. mi.. respectively. The relative
density index was measured at .66. 3) Summary Comparisons of the 1989-99
Sanctuary-wide Kelp Resource The total sanctuary-wide kelp resource canopv
area siqnificantlv decreased (p=,05) from 16.918
sq. mi. to 14.053 sq. mi., which represented a 17%
loss of surface canopy from that measured in 1989.
The 1989-1999 totai kelp bed planimeter area also
si~nificantlY decreased from 25.814 to 22.358 sq.
mi., which represented a 14% loss of perimeter
extent. The reiative densitY index also decreased
from .66 (1989) to .63 (1999), but was
statistically unchanged. The areatest loss in kelp canopy extent between
the two inventories was observed within the
Monterey Bay itself (CDF&G canopies 222, 221
and 220), and the ~reatest qain in kelp resource
extent was noted in canopy 217, between Yankee Pt.
And Pt. Sur.
