Evaluation of habitat suitability for brook trout ( Salvelinus fontinalis) in two southern Ontario streams using a standard assessment protocol: Watershed planning and management implications

Successful watershed planning and management requires an understanding of the ecological complexities of development backed by solid scientific research. Evidence from recent studies suggested that the quality and extent of coldwater ecosystems is decreasing in Ontario, particularly in areas of increased population growth. This study was an assessment of the extent to which two known coldwater streams in southern Ontario have been impacted by anthropogenic activities, thereby determining the potential for self-sustaining populations of brook trout (Salvelinus fontinalis); a coldwater indicator species. As part of the assessment, the research was used to further explore the effectiveness of a standard fish habitat evaluation procedure developed for southern Ontario streams as it relates to environmental planning and management. The Ontario Stream Assessment Protocol (OSAP) was used to evaluate habitat suitability for brook trout in Jones and Cedar Creek. Results indicated that both creeks, located in southwestern Ontario, could potentially support the species. (Abstract shortened by UMI.)...
