S. varius ssp.
Hope - Princeton Road, British Columbia
May 16 (cont'd) - The road runs through Manning
Park in a sort of a "V". The Falls is
near the upper right limb of the figure, and
Allison Pass is a little way up the ascending
limb on the left (W) side. At the pass,
4402 ft., with slopes rising to 6000 and
5500 ft. on either side, the forest is mostly
lodge-pole pine, locally called jack-pine.
Beyond the pass to the west is the 1945
"burn." Mr. R.F. Boyd, the Park Ranger, says
that the burn occurred at just about the
place where the coast forest blended into
that of the interior. The red cedar is a
good indicator of the coast forest, and it
comes right up to the western edge of the
burn. On both sides of the pass there is
Engelmann Spruce, Hemlock, Balsam, and-
Douglas Fir, and Lodge-pole Pine. It is
possible that the 1945 fire burned out the
area of intergradation of the sapsuckers,
at least that along the road. The road
follows the Skagit Creek (= Cedar Creek)
and there are enough cottonwoods along
the creek and live conifers scattered through-
out the burn to permit a continuous sap-
sucker population, but it could make for
small contacts and very limited interbreeding.
Now I want to record my impressions of the
ruber that I saw at close range today.
ruber looks definitely larger than nuchalis
