3 mi. N Willow Creek, 700 ft., Humboldt Co., Caly.
Sep. 1 (cont) I collected 1 Myla regilla from the
nearby forest floor. Crossbills were heard flying about.
After returning to Johnson Prairie we drove
to the summit of Brannan Mtn, 3957 ft. in
elevation, from where, a fine view over the
Trinity River valley & mountains as far
away as South Fork Mtn. & the Trinity
Alps. Took 1 photo here (w/ 1 at the bog).
The south-facing slope of Brannan Mtn. is
above about 3300 ft. and the N. facing slope
for a short distance below the summit is
of an entirely different aspect as regards
vegetation. It is clothed with an open
pine forest with scattered & dense shrubs
between the trees - much like the
southern California mountain forests.
Common trees were: Pinus jeffreyi, Pinus
lambertiana, Libocedrus decurrens, Pinus
attenuata (all individuals less than 30 ft. high), Litcha-
carpus densiflora (becomes shrubby on open
slopes), Quercus chrysolepis, Quercus kelloggii
(few, only). Shrubs identified were: Ceano-
thus cuneatus, Arctostaphylos nevadensis &
canescens, A. manganita?, Prunus sp., and
Quercus vaccinifolia (abundant). Douglas Fir,
madrone,
chaparral are mixed with this forest
for only a narrow strip & one comes
ruthles suddenly out of the Douglas Fir
