Eradicating invasive European fallow deer from Sidney Island to facilitate sustained forest recovery

Parks Canada is funding a collaborative project with the objective of facilitating long-term, sustained recovery of the at-risk Coastal Douglas fir forest ecosystem on Sidney Island, which is currently in a severely degraded state as a result of decades of browse pressure from introduced European fallow deer. The project area is the entirety of Sidney Island, including lands under federal administration (the park reserve) as well as lands administered by a residential strata corporation. The island is within the traditional territory of W_SÁNEC and Quw'utsun First Nations.

Since 2019, project partners have worked together to identify and approve a suite of restoration activities, including the complete removal (eradication) of European fallow deer, which is the focus of this Detailed Impact Assessment process.

This public review period is preceded by almost five years of collaboration and consultation with local First Nations and residential communities, as well as other government bodies. An initial public review period occurred in May 2021, during which the public was invited to provide feedback on the eradication proposal. The feedback from that period is included in the Detailed Impact Assessment report.
