MB Conservation: Climate Change
 Forestry Branch is conducting a vulnerability assessment to
explore potential impacts of climate change on forest
management in the Sandilands provincial forest
(southeastern Manitoba).
 The guidebook developed through the Canadian Council of
Forest Ministers (CCFM) is being used as a reference for the
assessment.
 The assessment will identify potential adaptation options
and will establish a vulnerability assessment tool that can be
applied to other areas within the province.
 SRC has generated climate forecasts which are being used to
assess anticipated climate change impacts.

Wood Supply and Climate Change in
the Island Forests
Used a forest ecosystem model (PnET) to produce
estimates of annual biomass production (NPP)
Converted NPP to the equivalent harvestable wood
volume
Generated these estimate for current and future
climate
Used these data to generate yield curves for main
forest types – used in wood supply analysis
Results will be incorporated into a 20-year forest
management plan for the Island Forests
