Special needs

Marbled Murrelets require late-successional forests with specific nest tree characteristics.

Limiting factors

Marbled Murrelets are adversely affected by reductions and modifications to late-successional forests. Habitat loss due to uncharacteristically severe fire is of particular concern in the Klamath Mountains ecoregion. Murrelets have low reproductive output and have experienced poor breeding success in some areas.

Conservation actions

Continue marine (at-sea) surveys to detect trends in Oregon. Continue inland surveys to detect presence and nesting locations. Monitor impacts to nesting success. Monitor and minimize impacts of ocean energy development projects. Lower predation rates by minimizing garbage at campgrounds near murrelet habitat.
