The broadest goal of the research covered in this thesis was to contribute
to our limited knowledge of high elevation forest soil ecology. Based on the reeds
of funding agencies, specific objectives were to examine 1) how climate-induced
Abies lasiocarpa ([Hook.] Nutt.) forest expansion affects soil nutrient pools, 2) the...
Abies lasiocarpa (Hook.) Nutt. (sub-alpine fir) trees of comparable
vigor growing in eastern British Columbia were studied in
order to determine the effects of cork bark disease on phellogen and
vascular cambium activity.
Diseased trees form hard deeply fissured rhytidome several
inches thick over large areas of the bole when...
