Work Restrictions in Unoccupied Habitat
If recent protocol surveys determine that all suitable marbled murrelet nesting habitat in the project area is considered unoccupied, the auditory, visual, and other disturbance measures listed in MAMU-1, do not apply. However, if marbled murrelet surveys (using the 2003 USFWS survey protocol or the most updated version of this guideline document; Evans Mack et al. 2003) determine that the project area is occupied, or if the Project Proponent presumes marbled murrelet occupancy without conducting surveys, the Project Proponent will adhere to the measures identified in MAMU-1, Work Restrictions in Occupied Habitat.
