It looks as though
last year, tide was
not shut off at the lake,
And the present Salicornia & dead S.campestriis
would have had more birds - still would
be an intermediate habitat however.
Of interest is distn. of Savannah Sparrow - inseparable
from SS in salt marsh - in intermediate
area was in grass, not tall Comu, etc.
More than SS in Salicornia, less in Grindelia.
