Went to Alcatraz Island w/ Ray Pinotti, Alan Fish,
Terri Thomas (GCNRA). Alan Fish had organized a
symposium on the gull situation on Alcatraz. Development
plans for Alcatraz, as laid out in the Lawrence Halprin
proposal, does not take the gulls into consideration. In
fact, in our meeting it was made clear that the plan
as it stands would 1) significantly adversely affect the
W. Gull population and 2) the W. Gull population
represents an important resource for both the Bay Area
and the N.P.S. (through the possibility of offering great
visits / gull interpretation). Since the colony is significant
250-300 pairs, some consideration for developing gull
nesting habitat should be made. The initial plan calls
for develop the Parade Grounds and open a perimeter
trail. Both will be OK if gull nesting habitat could be
improved on the cistern & industry building roof. In
addition, certain areas could be designated & managed
for gull breeding: e.g. incinerator area, NW store, etc.
Provided that barriers could be erected & grass mowed.
Perimeter trail should be opened in January to
allow gulls to adapt to regular visitors.
On Alcatraz I., many gulls on eggs, I'd
say about 1/3 of nests had eggs (slightly advanced
compared to Red Rock). Parade Grounds has
approx 40 nests. Island vegetation very lush-
lush - due to late rains.
On my return to SF I walked to
