Broadleaves and Mixedwood Management Research
Last updated on January 26, 2024Broadleaves and mixedwoods are a significant part of B.C.'s forested ecosystems, offering shelter and forage for many wildlife species and contributing to the overall biodiversity of this unique province. In addition, they are a renewable resource that provides employment opportunities now and in the future.
Our research concentrates on interactions between various broadleaf tree species and the surrounding vegetation.

Research
British Columbia has a long history of silviculture research in broadleaf and broadleaf-conifer mixedwood management with established field trials as early as 1935.
