Principle Findings
The principle findinqs
from the 2000 Monterey Bay National Marine
Sanctuary kelp resource inventory were summarized,
by CDF&G kelp bed numbers, as follows: 1) Summary of the 2000 Sanctuary-wide Kelp
Resource Extent The total 2000 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 1999 Sanctuary-wide Kelp
Resource Extent The total 1999 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 increased (p=,05) from 14.053
sq. mi. to 17.451 sq. mi., which represented a 24%
increase of surface canopy from that measured in
1999. The 1999-2000 total kelp bed planimeter area
also significantly increased from 22.358 to 24.663
sq. mi., which represented a 10% increase of
planimeter extent. The reiative density index also
significantly increased from .63 (1999) to .71
(2000). Although virtually all canopies within the
survey range showed in increase in surface extent,
the greatest increase was observed within the
Monterey Bay itself (CDF&G canopies 222, 221
and 220). Increases in canopy areas of 120%, 206%,
and 66%, respectively, were also observed within
these canopies. The only canopy to experience a substantial loss
in surface extent was canopy 208 (Cambria to Pt.
Estero), which was reduced by 24% in canopy area
and 14% in planimeter area.
