Description

The main objectives of this project were to summarize information and develop tools to aid the development of seed-transfer guidelines for reforestation practices under climate change. Genetic analysis of controlled parentage program (CPP) trial data and climatic summaries have been synthesized to develop holistic summaries of the white spruce (Picea glauca) and lodgepole pine (Pinus contorta) CPP programs in Alberta.

Description

The Tree Species Adaptation Risk Management project was initiated in 2012 with the aim of generating data, scientific-based inferences and recommendations that enable the Alberta government to adopt provincial policies that integrate climate change adaptation into seed and clonal transfer guidelines for reforestation in Crown land. This report is the first in a series of reports and journal articles which will be produced from the project. It covers projections of future climates for selected climatic variables for the entire province and individual tree breeding program regions, also called Controlled Parentage Programs (CPP) regions. These projections will be integrated with the ongoing analysis on biological data and CPP-based climate change risk analysis to address questions on transfer of wild seed among seed zones; transferability of orchard seed and clones among CPP regions; and reconfiguring seed orchards and deciduous species clonal production programs to address future...

A comprehensive set of interpolated climate data for Alberta

Description

We present an easily accessible database of interpolated climate data for Alberta that includes monthly, annual, decadal and 30-year normal climate data for the last 106 years (1901-2006), as well... More ≫

Description

We present an easily accessible database of interpolated climate data for Alberta that includes monthly, annual, decadal and 30-year normal climate data for the last 106 years (1901-2006), as well as climate change projections for the 21st century from 23 general circulation models. The database builds on the Alberta Climate Model and a set of five future projections that are recommended and widely used by Alberta government agencies. We added 15,000 historical and projected climate surfaces that include variables relevant for biological research and infrastructure planning, such as growing and chilling degree days, heating and cooling degree days, growing season length descriptors, frost free days and extreme minimum temperature. The database can be queried through a provided software package ClimateAB. A representative subset of these climate surfaces has been thoroughly checked against observed weather station data. We report error estimate for historical climate data and discuss...
