• Growth Intercept, Years-to-Breast-Height, and Juvenile Height Growth Models for Ponderosa Pine.
  http://www.for.gov.bc.ca/hre/pubs/pubs/0170.htm
  A suite of models consisting of height-age (site index), growth intercept, years-to-breast-height, juvenile height, and Site Index - Biogeoclimatic Ecosystem Classification (SIBEC) models are commonly used in British Columbia to estimate the height and site index of forest stands. Eighty plots of ponderosa pine stem analysis data were collected across the range of ponderosa pine in British Columbia. The years-to-breast-height, growth intercept, and juvenile height models were developed with these data. Height-age models were also developed, but are described elsewhere. The data were also used to further populate the SIBEC database. The growth intercept models were developed using standard techniques. The years-to-breast-height models used a slightly different functional form for the model. The juvenile height modelling technique was modified to more seamlessly splice the height curves into the height-age models. ...

• Field studies of seed biology.

  ctly involved in research activities. The detailed examples from previous studies are included, not to prescribe how such studies should be done, but to assist in planning by providing reference values on which to base measurements, sample sizes, and other experimental details. Since the manual is directed primarily to re-searchers working in the province of British Columbia (B.C.), Canada, many examples (forest types, species, research topics), procedures (the biogeoclimatic ecosystem classification system), and regulatory policies are specific to this geographic and political jurisdiction. Nevertheless, it is hoped that the underlying principles are self-evident and will be generally applicable to the conduct of field research elsewhere. ...

• Spatial climate data and assessment of climate change impacts on forest ecosystems.
  http://www.for.gov.bc.ca/hre/pubs/pubs/1392.htm
  d significant improvements over original PRISM climate data. A stand-alone MS Windows application (ClimateBC) was developed to perform all calculations and to integrate predictions of future climate from various global circulation models. Examples of applications of the spatially distributed, scale-free data are presented. Data produced by ClimateBC was used to determine climatic moisture deficits on an elevation transect on Vancouver Island. Climate data at 400 m grid spacing were overlain on subzone variant maps of the Biogeoclimatic Ecosystem Classification system to provide descriptions of variant climates. This was repeated for future possible climates and assessments made of changes in climate of selected ecosystems and potential responses of the vegetation. The influence of climate change on snow accumulation and melt at a high-elevation forest site was evaluated. Data and programs are available through web sites. ...

• Garry Oak (
  http://www.for.gov.bc.ca/hre/pubs/pubs/1421.htm
  This field guide covers the native plant communities with a component of Garry oak (Quercus garryana) in British Columbia. It is a guide to identification of these communities, which can be applied to the woodlands, savannah, meadow, and rock outcrops within and near the zone of influence of oak canopy. The guide does not cover very specific occurrences, such as vernal pools, or the broader set of associated ecosystems that help form the Garry oak landscape. In the background work (Erickson 1996, 1998, 2002b) on which this guide is based, Garry oak ecosystems were interpreted as a climax conditioned by a natural disturbance regime. This would occur within a smaller geographic scale than that addressed by the provincial biogeoclimatic ecosystem classification (BEC). In the BEC context they are placed as seral in comparison to climax Douglas-fir forest on circum-mesic sites, and could possibly be considered as a disclimax. This guide does not focus on management, which is addressed only via rankings a ...
