Copyright © SRC 2012 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. MB Conservation: Climate Change
