Uncertainties Linking Tailed Frog Habitat and Population Dynamics With Riparian Management (in Proc. Conference Biology & Management of Species and Habitats at Risk) Sutherland, Glenn D.

Abstract: Efforts to quantify risks of alternative forest and habitat management options to populations of species considered vulnerable to forestry practices are usually limited by uncertainties in their habitat associations, as well as basic life history and population trend data. Identifying “disturbance/management envelopes” within which populations are likely to persist remains difficult for several reasons: species’ requirements are incompletely known; only some life stages are practically accessible for monitoring; and different environmental factors may operate on populations across a species’ geographic range. We confront this problem for the tailed frog (Ascaphus truei) in British Columbia by combining 2 approaches. First, we use hierarchical classifications of habitat variables measured in province-wide surveys to identify contingencies in environmental conditions that may alter likely responses to habitat protection measures...
