Over the past 150 years, waves of settlers have been attracted to Vancouver Island’s southeastern coast. Land conversion for agricultural, residential and industrial development has vastly reduced the extent of Garry oak ecosystems. Less than 5% now remains in a near-natural condition, and that too is threatened.
Threats include habitat loss, fragmentation of larger areas of habitat into smaller, more vulnerable patches, encroachment of woody species as a consequence of fire suppression, and invasion of exotic species that out-compete native species.
