26. 23 Contra Costa-Alameda Co., Calif.
We proceeded down Skyline Blvd. to Redwood Rd
where we turned down the canyon & on down,
continued past San Leandro Reservoir. Photos
from opposite the dam. On W, facing hills
directly south of the dam we noticed Baccharis
invading the grassy areas. The hills here are
very interesting for the east facing slope is
mainly Baccharis, minor amounts of evergreen
oaks and some isolated clumps of Acer macrophyllum
and Emblactus c - as far as I could determine
from flaccities. Further down the canyon - above
L. Chabar is an extensive area of riparian
growth - mainly Salix, Alnus, Umbellularia
(which was blooming everywhere where we
observed it). Visited the Narrows on Crow Canyon
Rd. Left that & proceeded up the road & turned
down Norris Canyon Rd. The country here is
open grassy hills with dense riparian growth
and limited groves of oaks. Photos just over
ridge looking east. San Ramon - Danville, etc.
to Pleasant Hill and dark then Alhambra V - (Bear
Hampton Rd.
Impressions: There are two main "communities" -
Baccharis and Broad-leaved leafy forest. They mix in
places to the extent that the oak is interspersed with
the shrubs. The rather different riparian growth should
be considered a broad type typical over much of
the state. Sycamores were rare - (saw on Crow Camp Rd.)
The grassy areas is a paradox - a count
(figure is not as yet. Many extensive & recent)
landslips - most from last year I believe.
Where does the Baccharis meet the Charnie
to the S?
