A study is looking into why birch trees are dying off in the prairies and British Columbia, but a researcher says they can be saved.
Natural Resources Canada started the study in 2008 to focus on the state of birch health. The study has examined over 300 birch tree plots in urban centres.
David Langor, a research scientist working on the study, noticed birch trees were starting to die off at a rapid rate in 2003 and set out why.
Langor says Edmonton has lost 60 per cent of its birch population since 2008. So far he's found that the deaths are climate related. He speculates it's a combination of drought and more frequent freeze-thaw periods in the winter. read more >>
