Decide whether or not to fly the survey. This is a somewhat subjective call, but current and forecasted weather, especially ceiling height and cloud density, visibility, wind and rain are the main components that go into making that decision. Wind >15kts, ceiling <2,000ft, steady rain or visibility <5 mi generally results in a “no go” for flying the survey at that time. If any of these conditions are forecasted in the following 4-6 hrs, also generally calls for waiting for better conditions or forecasts.If a survey is a “go”, the survey aircraft departs Nelson Lagoon airstrip and flies east toward transect number 1. All photographic gear, cameras, computers, screens have been previously set up and software tested....

Summary The impact of climate change on cold-water ecosystems—and the cold-adapted native salmonids present in these systems—is the subject of a substantial body of research.. Recently, scientists have developed a number of datasets and analyses that provide insight into projections of climate change effects on native salmonid populations in the northern U.S. Rockies region. Alongside this research, a number of management options for helping native salmonids respond to the effects of climate change—also known as ‘climate adaptation’ strategies and actions—have been identified by scientists and managers in the region. These analyses and climate adaptation options offer valuable information to managers charged with...

Historically, available den habitat models have been based primarily on the presence of topographic features capable of capturing drifting snow. In any given season, however, the availability and precise location of snowdrifts of sufficient size to accommodate a bear den depends on the antecedent snowfall and wind conditions, and these vary from one year to the next. Thus, suitable topography is a necessary pre-condition, but is not sufficient to accurately predict potential den sites in a given year.To satisfy the requirements of agency and industry managers what is needed is a user-friendly decision-support tool that takes into account the current fall and early-winter meteorological conditions, and provides den...
