Climate Change Research
Climate modeling & software development
As a foundation for climate change impact research, it was necessary to develop new spatially
and temporally explicit models of biologically relevant climate variables, such as chilling and
growing degree days, frost free period, snow fall, dryness indices, etc. The models and algorithms
form the basis for a Microsoft Windows application, where users can query climate data for any location
of interest. Batch processing of Excel spreadsheets with multiple locations or generating high-resolution
GIS coverages of climate data is also possible. The program generates up to 50 variables for
30-year averages (climate normals), selected 5-year averages, more than 500 annual and monthly
averages from 1960 to 2003, and predictions for the 2020s, 2050s, and 2080s from 18 global circulation models.

Climate change impact research
The project was originally commissioned by the B.C. Ministry of Forests to assess the potential impact of
climate change on management of forest genetic resources, but was expanded to also include more general ecological
impact assessments. In this project we utilized and developed advanced statistical methods to synthesize information
from extensive provincial databases, including timber supply inventories, botanical records, and genetic field trials.
This research is inter-disciplinary by nature, including ongoing projects with wildlife biologists, forest pathologist,
and community ecologists.
