Previous reports in the series have included: a review of conservation objectives formulated by previous land use planning processes (Scott-May 2002b), a Conservation Risk Assessment of selected parks in the region (Scott-May 2002a) and a summary of the ecological context for protected areas in the Central and Southern Columbia Ecosections (CCM, SCM, Utzig et al. 2003). This phase is a pilot project to examine the effectiveness of the protected area network in the CCM and SCM ecosections, the potential ecological conservation roles of selected protected areas, and where appropriate, to provide recommendations on how changes in park management might improve the ability of those parks to fulfil their ecological conservation roles. The provincial parks examined in more detail for the CCM include: Valhalla, Kokanee Glacier, McDonald Creek, and Cody Caves; and for the SCM include: West Arm, Stagleap, Kokanee Creek, Midge Creek and Moyie Lake. For the purposes of this project “ecological conservation” is used to denote the maintenance and/or restoration of ecological integrity, including maintaining and/or restoring ecosystem patterns, functions and processes that are responsible for biological diversity, the critical types and ranges of natural variation in ecosystems, and ecosystem resilience. It does not include conservation of post-European contact historical or cultural features. Two primary ecological conservation roles are recognized for protected areas: • representation – inclusion of a complete cross-section of environmental conditions and ecosystems within a network of protected areas, and • provision of local habitat supply – providing habitats necessary for the maintenance and/or restoration of biological diversity within the local area, often in concert with surrounding unprotected landscapes. Representation was systematically assessed at various levels, including ecoregions, ecosections, biogeoclimatic variants, landscape elements and site series. Representation was also subjectively examined at the ecosection level for major bedrock types, terrain and soils, watersheds and other aquatic features, and geographic distribution. Representation was analyzed with respect to two aspects: • providing areas in an undisturbed state where ecosystems are relatively unaffected by human activities such that they can serve as baselines or control areas for assessment of the impacts of land management practices on other similar areas, and • a coarse filter approach to biological conservation where protection of a percentage of the occurrence of each ecosystem is assumed to guarantee perpetuation of the species associated with those ecosystems. Local habitat supply was examined by assessing the range of habitats and species present within the protected area, the management regimes and human activities occurring within the park and the surrounding area, and habitat requirements of selected species that are naturally occurring within the protected area. Because many of the protected areas examined are small (<500 ha) and yet include wide-ranging species that depend on geographically dispersed habitats for seasonal and/or life-cycle requirements (e.g. caribou, grizzly bear, great blue heron, kokanee), the assessments employed the “greater park ii ecosystem” concept to identify areas outside the protected areas that are necessary for maintaining and/or restoring ecological integrity within the protected area itself, including its full complement of species (Zorn et al. 2001). The greater park ecosystem concept is an attempt to delineate an area that encompasses the full extent of ecosystem functional relationships that impact on the ecological integrity of an individual protected area. Ideally greater park ecosystem boundaries are consistent with natural ecosystem boundaries (e.g., watersheds or species/ population home ranges), reflecting the dominant ecosystem processes and functions that determine the environmental characteristics and biodiversity that are found in the protected area. Within the greater park ecosystem, consideration was then given to the administrative relationships that are necessary to achieve the ecological conservation goals of a protected area. While park administration controls management within the park portion of the greater park ecosystem, park managers must seek cooperation from a variety of agencies and stakeholders whose mandates or interests relate to areas outside of the park boundaries. For the purpose of this pilot project, an “area of cooperation” was generally defined on the basis of existing administrative boundaries that were related to decision-making and stakeholder actions that potentially affect the ecological integrity of the greater park ecosystem (e.g., landscape units, caribou management areas). Assessments for each of the selected parks include a review of past and present use patterns and management regimes, as well as the ecological context of the park, ecological features of the park, threats to maintaining and/or restoring ecological integrity, and potential ecological conservation roles. Following analysis of the available information for each park, recommendations for adjustments to management direction and other specific actions are provided to assist with improving each park’s fulfillment of its identified ecological conservation roles. Inadequate species and habitat inventories and a lack of understanding of natural disturbance regimes were found to hamper scientifically based ecological planning and management in all the parks examined. Although all parks likely require greater cooperation with managers and stakeholders in their greater park ecosystem and area of cooperation, the need is even greater in the smaller parks and those where wide-ranging species are a focus. Common themes that emerged for smaller parks are loss of ecological integrity due to transportation corridors, presence of invasive species and high intensity recreational use. The use of public education to assist with meeting the challenges of managing for ecological integrity in parks was identified as a potential opportunity for facilitating reductions in environmental risk, especially in those parks with high levels of recreational use (although it is recognized that government restructuring has recently eliminated such programs from the core mandate of MWLAP). The final chapter of the report provides discussion and recommendations regarding the ongoing project of examining the ecological conservation roles of protected areas in the Kootenay Region, broader issues identified during the pilot project and ecological conservation issues in the CCM and SCM ecosections in particular. Highlights of the recommendations include: • that MWLAP complete the assessments for the remaining protected areas in the CCM and SCM, review and update the ecosection network assessments, and then examine the opportunities of coordinating this project with other related initiatives (e.g., the provincial biodiversity strategy, results-based FPC monitoring); • that MWLAP select a group of parks within the CCM/SCM for development of more detailed management strategies for implementing the recommendations for improving ecological conservation, including formation of appropriate partnership group(s) in the area(s) of cooperation/ greater park ecosystem(s); • that BC Parks improve coordination with other government departments and stakeholders and provide more clarity around the ability of individual protected areas, or portions of protected areas to fulfill ecological conservation roles within a broader ecosystem management framework (especially representation – baseline/control roles); iii • that BC Parks strengthen its Conservation Risk Assessment procedures; • that MWLAP and MSRM improve ecological inventory information for protected areas, and better coordinate data collection, storage and analysis to facilitate joint planning for protected and non- protected portions of the landbase; • that MWLAP explore the possibility of amending the appropriate provincial parks legislation to provide clear and unequivocal direction to set maintaining ecological integrity as the primary objective in the management of protected areas, similar to the Federal Parks legislation, and instituting preparation of ecological integrity statements to guide conservation planning and management for provincial protected areas; • within the CCM, that MWLAP investigate expansion of the protected area network to fill critical gaps in representation, especially at lower elevations, and further investigate the range of natural variation in this ecosection to provide a basis for setting
