| Résumé | (disponible en anglais seulement)
Within fisheries science and coastal development, there has been a need for methods, models and tools for assessing project effects on fish habitat and for
evaluating potential for offsetting of these impacts. For this reason we have developed The Habitat Ecosystem Assessment Tool (HEAT). This tool is an application of a quantitative fish habitat assessment for use in evaluating proposals (such as
infills) affecting lacustrine fish. We have developed relationships that use fish lists, guild assignment, guild weighting as well as their thermal and habitat requirements to build a habitat suitability matrix (HSM) to estimate the habitat
suitability indices along with the rules and criteria that must be applied to allow evaluation of fish habitats. The HSM model uses pooled matrices representing the aggregate habitat preferences of species by life stage to ensure that all needs
during that critical stage are met for survival for each species. Using this data we can perform pre- and post-project assessment of limnological and physical habitat changes and their impact on fishes through scenario-testing. We have also tested
climate driven variables such as water levels and temperature scenarios in the existing assessment to address changing depths that occur with climate change. |
