Research Wildlife Biologist And Team Leader, Wildlife Ecology
Contact Martin Raphael
My current work is exploring the population ecology of the marbled murrelet, a threatened seabird that nests on limbs of large coniferous trees in coastal zones of the Pacific Northwest. I also am investigating habitat relationships of the northern spotted owl and American marten.
Wildlife ecology and habitat relationships; population dynamics; ecology and management of threatened, endangered, or sensitive wildlife.
My past work focused on the ecology of cavity-nesting birds, efficacy of riparian buffer systems on sensitive wildlife, and habitat relations of vertebrates associated with older forests.
Why This Research is Important
My work helps inform land managers about potential effects of alternative land management options on wildlife and provides information to help guide development of new management options. My research helps to advance the science of wildlife management.
