• The Upper Penticton Creek Watershed Experiment 2002.
  http://www.for.gov.bc.ca/hre/pubs/pubs/0096.htm
  In 1982, three small watersheds, tributaries to Penticton Creek, were set aside for long-term study to improve our understanding of how forest land use affects streams, aquatic organisms, streamflow, and water quality. The Upper Penticton Creek Watershed Experiment is a collaborative effort of provincial and federal governments, universities and industry. The experiment follows a paired-watershed design in which one watershed remains the undisturbed control throughout the experiment. The watersheds of 240, 241 and Dennis Creeks are 26 kilometres north-east of Penticton, BC. Each watershed covers an area of approximately five square kilometres and an elevation range of 1600 meters to 2100 meters. The predominant forest cover types are lodgepole pine and Engelmann spruce/subalpine fir. Hydrometric monitoring began in all three watersheds 10 years prior to development in 1995 and has continued through- and post- logging. Project description and preliminary findings are presented. ...

• Structure and dynamics of a nearly steady-state subalpine forest in south-central British Columbia, Canada.
  http://www.for.gov.bc.ca/hre/pubs/pubs/1132.htm
  We examined the size, age, and spatial structure of trees in an old Engelmann spruce (Picea engelmannii)-subalpine fir (Abies lasiocarpa) forest based on four stem-mapped, 0.25 ha plots. Dendrochronological techniques were used on basal discs of 1,190 trees to reconstruct age and growth pattern, including dates of rapid growth increases. There were no obvious age cohorts or other evidence of past major disturbance. The abundance of both subalpine fir and spruce decreased rapidly with age, especially beyond the ages of 150 years. Very old trees were present, but rare. The best evidence from tree-ring width patterns for past disturbance was a period of release 100 years ago. However, few of the released trees grew into the canopy, which suggests a disturbance of low intensity. Patch dynamics and gap processes were not pronounced in the stand. Clumping was generally weak and only present at small spatial scales ( ...

• Revised Growth Intercept Models for Coastal Western Hemlock, Sitka Spruce, and Interior Spruce
  http://www.for.gov.bc.ca/hre/pubs/pubs/1217.htm
  The original growth intercept models for Sitka spruce (Picea sitchensis [Bong.] Carr.), coastal western hemlock (Tsuga heterophylla [Raf.] Sarg.), and interior spruce-white spruce (Picea glauca [Moench] Voss), Engelmann spruce (P. engelmannii Parry), and their hybrids - are dated. The original data, plus some additional data for interior spruce, were re-analyzed to incorporate new techniques into the models. The resulting models for Sitka spruce are more precise than the original models, although the revised models for western hemlock and interior spruce are slightly less precise. The advantages of the new techniques outweigh any loss of precision. The models for these species are upgraded to current standards and are consistent with models for other species. ...

• Seed source selection and deployment to address adaptation to future climates for interior spruce in western Canada.
  http://www.for.gov.bc.ca/hre/pubs/pubs/1403.htm
  Climate change is already signficantly affecting the health and productivity of Canada’s forests. Planted forests that are adapted to today’s climate will be maladapted when they are harvested in 60-80 years. However, if seedlots for reforestation are selected so as to maximize their adaptation over the duration of their rotation, productivity of Canada’s forests could be enhanced by capitalizing on increased future temperatures. To ensure that the most economically important tree crop planted in Canada - interior spruce (white and engelmann spruce and their hybrids) - is adapted to future climates, forest scientists from western North America have initiated a long-term project that will act as a cornerstone to the genetic resource management of interior spruce in western North America, and as a model for other species and regions. Wild and domesticated interior spruce seedlots from 128 locations encompassing the climatic and latitudinal range of interior spruce in western North America have been caref ...
