Application of radar surveys in the management of nesting habitat of Marbled Murrlets Brachyramphus marmoratus

High-frequency marine radar has been successfully used to estimate and monitor local populations of Marbled Murrelets Brachyramphus marmoratus in diverse situations and is becoming a standard tool for these purposes across the species’ range (Hamer et al. 1995; Burger 1997, 2001, 2002a; Cooper et al. 2001; Cooper & Blaha 2002). Radar is the method recommended for long-term monitoring of population changes and the effects of habitat changes in Canada [Canadian Marbled Murrelet Recovery Team (CMMRT) 2003].
