Red Marker Boardman Grasslands
The 69,000-acre Boardman Grasslands IBA is the largest remaining single block of predominantly native shrub steppe and grassland habitats in the Columbia Basin. This IBA is in Northern Morrow County in NE Oregon.

Location: Boardman Grasslands IBA sits just south of the city of Boardman in Morrow County.  The site contains a Naval Training Facility and there is no public access permitted.

Description: The Boardman Grasslands IBA consists of two adjacent parcels totaling approximately 69,000 acres: the Boardman Conservation Area and the Boardman Bombing Range (Naval Weapons Systems Training Facility Boardman). High-quality occurrences of bitterbrush (Purshia tridentata) shrub steppe, Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis) steppe, basin big sagebrush (Artemisia tridentata ssp. tridentata) steppe, bluebunch wheatgrass (Pseudoregneria spicata) grasslands and needle-and-thread (Heterostipa comata) grasslands occur here. This basin has been laregly converted to dryland and irrigated agriculture, making this IBA critical habitat for a number of native wildlife species, including ten state and/or federally-listed threatened, endangered, or sensitive wildlife species.

Ornithological Highlights: This site supports what are suspected to be the largest nesting populations in Oregon for Grasshopper Sparrow, Long-billed Curlew, and Burrowing Owl. Significant regional nesting populations of Swainson's Hawk and Ferruginous Hawk use the Juniper Canyon area of the bombing range. Other Partners in Flight focal species for conservation that occur in shrub-steppe habitats in the IBA include: Loggerhead Shrike, Sage Sparrow, Sage Thrasher, and Lark Sparrow. This range contains areas of ungrazed native bunchgrass and big sagebrush habitat. Nearly all of the area has current or planned wind power projects.
