<strong>Whitehorse</strong> <strong>Climate</strong> <strong>Change</strong> <strong>Adaptation</strong> <strong>Plan</strong><br />

Community Consequences Associated with Infrastructure, continued.<br />

Community vulnerability from climate-induced environmental stresses in the <strong>Whitehorse</strong><br />

region stems from an increasing presence of damaging invasive species, changes to the quality/<br />

productivity of the environment, and increasing pressure on local wildlife. The resulting risk to<br />

the community is characterized by declining water quality, shifting landscape conditions, and a<br />

changing community relationship to the environment.<br />
