Cogswell 1949 Journal 101 3 mi. N Willow Creek, 700 ft., Humboldt Co., Calif. Sep. 1 (cont.) indicates that it was once covered with that type of forest (possibly with Douglas Fir or pines). Beyond this terrace, and up to about 1200 ft. elevation, the road passes thru a Douglas Fir - Tan Oak - Madrone forest of much the same nature as near French Camp (see p. 82), Extending somewhat similar to #2 both up & down slope from the 1200 ft. elevation on the road is a low ridge covered with a low chaparral composed of Ceanothus cuneatus with very few Arctostaphylos manzanita. The Ceanothus looks greatly browsed down (by deer I assume). In the forest border around this area there are also some Rhus ponds rosa and a lot of Libocedrus decurrens, under which Rhamnus californicus & Chis diversifolia grow in an understory thicket with a little of the Ceanothus cuneatus mixed in. Ceanothus integerrimus is also occasional here or on the exposed road cuts thruout the Douglas Fir forest. Another such chaparral covered ridge with the same sort of forest border was noted about 1 mile farther W. at about 200 ft. elevation. We did not work the shrub areas themselves, but in the thick Ceanothus near the forest border at 1200ft. we heard a kind of call note, new to us, which apparently emanates from a chipmunk which will not respond to any of our techniques by exposing himself.
