The preparation of suitable sites for planting and growing of tree seedlings following logging is recognized by British Columbia Forest Service as a major silvicultural problem in the Central and Northern Interior regions of the province. Over the past few decades, scarification trials have been made with various types of...
A field study was established to determine the impact of interfering vegetation on survival and growth of Engelmann spruce (Piceaeigelmannii Parry) and lodgepole pine (Pinus contorta var contorta Dougi.) at a site in the high elevation Engelmann spruce-Subalpine fir (ESSF) zone, of south-central British Columbia. The study examined (1) the...
In this thesis, we present the first detailed, long-term seismotectonic studies of oceanic
ridge-transform systems. The proximity of the Juan de Fuca plate to a network of
broadband seismic stations in western North America provides a unique synergy of
interesting tectonic targets, high seismicity, and recording capabilities. Our main tools...
The western part of the Late Cretaceous Nanaimo Basin
is exposed on Vancouver Island at Nanaimo, British Columbia.
The five lowest members of the Nanaimo Group are present
and represent a complete sedimentary cycle. The two lowest
formations, the Comox and Haslam, represent the marine part
of the cycle. The...
The Taylor-Windfall gold prospect, located in south western British Columbia, is hosted by Cretaceous tuffaceous andesites, underlain by granodiorite phases of the Coast Range Plutonic Complex. Mining exploration companies were attracted to the area because of low transportation costs, and a favourable geologic environment defined by high angle deep-seated faults,...
The purpose of this study was to better understand the historical development of the British Columbia (B.C.) community college, university college, and institute system with the focus on the changing nature of voluntary inter-institutional collaboration in relation to provincial coordination. The study also examined the related themes of centralization and...
The bedrock of Thetis, Kuper, and seven adjacent islands and
islets of British Columbia's Gulf Islands consists of four Late Cretaceous
(Campanian) formations of the Nanaimo Group. The four, from
oldest to youngest, are the Cedar District, De Courcy, Northumberland,
and Geoffrey Formations.
The formations vary greatly in thickness but...
The Bethlehem Copper Mine, a porphyry copper deposit, is
situated near the geographical center of the Guichon Creek batholith.
The Guichon Creek batholith is located on the east flank of the
Canadian Coast Range in south central British Columbia approximately
250 miles northeast of Vancouver, B. C. The batholith
trends...
The root disease fungus Inonotus tomentosus, common in the old
growth boreal forests of British Columbia, poses a threat to the
health of second growth forests established on sites with a previous
history of root disease. Colonized stumps occur in groups of 1 to 6;
the groups are clumped within...
