Species Research & Monitoring - Upland Forest

Marbled Murrelet Studies

We conducted radar surveys in several locations in the watershed

From 2005 to 2007 we conducted baseline surveys for marbled murrelets within the municipal watershed using both standard audio-visual techniques as well as ornithological radar. We documented low numbers of murrelets flying over the watershed during all three years. Two patches of old-growth forest in the upper watershed were found to be occupied, very likely by nesting murrelets.

We are currently evaluating potential marbled murrelet habitat in second-growth forest stands. If sites are found that contain adequate nesting habitat and density of suitable nesting platforms, they will be surveyed for marbled murrelet occupancy. We are also developing an experimental research project to enhance potential marbled murrelet nesting habitat in selected second-growth forests within the watershed.
