Using strategic environmental assessment and project environmental impact assessment to assess ecological connectivity at multiple scales in a national park context

Abstract

ABSTRACT Ecological connectivity within and across the boundaries of protected areas has become a key theme for conservation practitioners in Canada and internationally in recent years. This paper describes four case studies involving the assessment of ecological connectivity in national parks in Canada. Assessments occurred in three tiers: strategic environmental assessments conducted during management planning processes, an intermediate tier focussed on research and partnering at more refined spatial scales, and project level environmental impact assessments. While improved data, modelling and research on thresholds is needed, the multi-tiered approach facilitated the analysis of information and the collaboration with partners at scales required to conserve ecological connectivity within and across the boundaries of national parks. This work demonstrates practical approaches to conserving ecological connectivity as a response to biodiversity loss and highlights impact assessment in multiple tiers as a solution that is transferable to other sectors.
