Marbled Murrelet IBA
-
80,000 acre land and marine-based parcel which houses high concentrations of Marbled Murrelets both on the water and in prime intact old-growth forest.

Location: This central coast IBA is composed of Siuslaw National Forest land, two BLM managed areas- Rock Creek Wilderness and Cummins Creek Wilderness-, Pine Tree Conservation Society land, and the Audubon Society of Portland-owned Ten-Mile Creek Sanctuary. The Heceta Head Lighthouse marks the southwestern edge.
Description: This IBA captures the largest intact stand of coastal temperate rainforest in the lower 48 states, a habitat of Douglas Fir, Western Hemlock, and the massive Sitka Spruce whose moss-blanketed branches provide nesting platforms for the Marbled Murrelet. Paul Engelmeyer, Coastal IBA Coordinator, manages the land for Portland Audubon with a litany of land management goals: improve forest canopy, encourage wildlife habitat diversity, encourage succession to old-growth forest characteristics, create a model for community based protection and restoration efforts, and to influence Siuslaw National Forest land management programs to shift toward a protection and restoration strategy for the surrounding forest.
Ornithological Highlights: The highest concentration of at-sea Murrelets occurs between Florence and Newport and the land included in the MAMU IBA contains more than 50 detected nest sites.
Northern Spotted Owls also nest within the IBA, and both of these ESA-listed species continue to face significant threats throughout their Pacific Northwest forest habitat.
The forests of the MAMU IBA additionally host a variety of songbirds including Hermit Warbler, Black-throated Gray Warbler, Varied and Hermit Thrush, Hutton’s Vireo, Pacific-slope Flycatcher, Common Yellowthroat, Black-headed Grosbeak, and MacGillivray’s Warbler.For more information on Marbled Murrelet IBA, please see the Technical Site Report in the National IBA database.
