Establishing Shrubs in Protective Fenced Areas to Facilitate Forest Restoration on Sidney Island

Many decades of high-intensity browsing by deer on Sidney Island has greatly reduced the abundance and diversity of plants in the forest understory. The result of this pressure is that the forest on Sidney Island has lost much of the species diversity and structural diversity it once had: fewer tree species are able to grow into saplings to replace older trees as they die, and the understorey has nearly disappeared. The forest will continue on this trajectory unless effective restoration work is done. Therefore, the objective of this project is to establish pockets of native shrubs in the Park Reserve that would rejuvenate the forest understorey, both where they are planted and also throughout the forest by producing seeds. To accomplish this objective, we propose building ten small, fenced areas (10-meter by 10-meter) that prevent deer browsing and planting native shrubs within them. Fencing will not be permanent: the fenced areas will be constructed to last several years (3 – 10) to give the shrubs time to become well established, after which time the fences will be removed. The work will occur seasonally during 2021-2023. This project will be assessed with a basic impact assessment.
