- Anderson Butte - Sterling Ditch
Shrubland and forest land managed by the Ashland Resource Area, Medford District of the BLM in south-central Jackson County which includes ceanothus-manzanita brushfields and scrub oak habitat.
Location: Near the city of Jacksonville in south central Jackson County, on BLM lands up Little Applegate Road (lands north of Little Applegate River) past the junction with Sterling Creek Road. Takes in Wolf Gap, Tunnel Ridge, and Goat Cabin Ridge.
Description: Anderson Butte/Sterling Ditch IBA falls entirely within the ODFW Anderson Butte Conservation Opportunity Area, and contains the BLM Sterling Mine Ditch Area of Critical Environmental Concern, which was designated for both cultural and botanical resources. Anderson Butte is an east-west trending ridge north of the Little Applegate River containing Northern Spotted Owl core areas, the north slopes of which are forested and heavily-roaded for timber harvest activity. The south slopes are a mosaic of habitat with high biodoversity of plants supporting unique guild of species.
Ornithological Highlights: This habitat is highly important to a very specific bird community that includes Blue-gray Gnatcatcher, Wrentit, Oak Titmouse, and California Towhee. All but the Wrentit are near the northern extent of their range in this IBA, and all but the gnatcatcher are year-round residents in this habitat. In addition, the manzanita in these shrublands provides resources to a diversity of birds year-round. During winter, manzanita provides a berry food source for several species, particularly Hermit Thrushes. In early spring, manzanita flowers provide a nectar heavily used by arriving Rufous Hummingbirds. The flowers are also eaten by songbirds such as Purple Finches and Golden-crowned Sparrows before and during spring migration. Photo by Dennis Vroman

- Ankeny National Wildlife Refuge
One of three large National Wildlife Refuges in the Willamette Valley, Ankeny NWR consists of flat to gently rolling land near the confluence of the Willamette and Santiam rivers.
Location: In the central Willamette Valley, southwest Marion County, about 10 miles south of Salem. Ankeny NWR is just west of I-5 at exit 243.
Description: One of three large National Wildlife Refuges in the Willamette Valley, Ankeny consists of flat to gently rolling land near the confluence of the Willamette and Santiam rivers. It was established in 1965 to provide winter habitat for Dusky Canada Geese, a subspecies that winters primarily in the Willamette Valley. Four other subspecies also regularly winter here. Riparian cottonwood and ash forests, oak woodland, wet prairie, and hedgerows provide habitat for other wildlife and native plants. (Contributed by Karen Viste-Sparkman)
Ornithological Highlights: Riparian habitat on the refuge support Yellow Warblers and Willow Flycatchers, both species that have been identified as focal species by Partners in Flight. No formal surveys have been done to estimate populations, but the Yellow Warbler population is estimated to be around 25 pairs during the breeding season. Ankeny supports large concentrations of geese and ducks during the winter. The 2000 mid-winter waterfowl count total was 38,435 ducks and geese. Peak numbers probably exceed this total, since over 32,000 geese alone have been counted roosting on the refuge. The refuge has also supported large flocks of Dunlin, with estimates peaking at 20,000 birds. Concentrations of other shorebirds can frequently be found on the refuge during migration.

- Baskett Slough National Wildlife Refuge + Livermore Road
Baskett Slough NWR is one of three large Willamette Valley National Wildlife Refuges and sits in the west-central Willamette Valley, about 10 miles west of Salem, in Northwestern Polk County. Adjacent land along Livermore Road is also included in this IBA.
Location: West-central Willamette Valley, about 10 miles west of Salem, in Northwestern Polk County.
Description: This national wildlife refuge was established in 1965 to provide winter habitat for Dusky Canada Geese, a subspecies that winters primarily in the Willamette Valley. Four other subspecies also regularly winter here. Oregon white oak woodland, oak savanna, and upland prairie provide habitat for other wildlife and rare native plants. (Contributed by Karen Viste-Sparkman).
Ornithological Highlights: Baskett Slough and nearby private lands provide habitat for one of the largest concentrations of the Streaked Horned Lark (Eremophila alpestris strigata), which is currently a candidate for listing under the Endangered Species Act, and is listed as critical on the Oregon sensitive species list. No formal surveys have been done on the refuge alone, but anecdotal information estimates a population of at least 10 breeding pairs. Together with adjacent private lands the breeding population easily exceeds 25 pairs. The entire population in the Willamette Valley is estimated to be less than 200 pairs. The refuge also supports a rare community of upland prairie and Oregon white oak woodland/oak savanna. Restored wetlands support concentrations of wintering waterfowl, and the mid-winter waterfowl survey detected 35,988 ducks, geese, and swans in 2001. The refuge regularly supports more than 100 shorebirds during spring and fall migrations. (Contributed by Karen Viste-Sparkman).

- Bird Rocks
Bird Rocks is a seabird colony rock off the coast of Chapman Point (north of Cannon Beach), which is included within the Oregon Islands NWR. The Bird Rocks Colony includes four large rocks including seabird colony #'s: 219-017, -018, -019 and -020.
Location: On the northern Oregon coast, just north of Cannon Beach, near Ecola State Park in southwest Clatsop County.
Description: This site is a small portion of the Oregon Islands NWR. It is comprised of four large rocks, one of which contains low vegetation, the rest of which are largely devoid of both vegetation and soil.
Ornithological Highlights: Over 200 Brown Pelicans have been observed at this site. These rocks support more than 6% of Oregon's breeding population of Common Murres and 27% of the state's breeding Brandt's Cormorant population. A total of 49,542 seabirds have nested here, comprised of six species. Bald Eagles routinely forage on seabirds at this colony, and significant increase in bald eagle predation has been causing widespread nesting failure at these colonies since 1994. Some abandonment of this site is occurring. Low flying aircraft, close approach of boats, and humans on the adjacent mainland can cause colony disturbance. Educational efforts are underway to alleviate these problems.

- 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.

- Bonney Butte
Bonney Butte IBA is at the southern terminus of Surveyor’s Ridge on the southeast slope of Mt. Hood within the Mt. Hood National Forest. HawkWatch International runs a migratory raptor observation site on a mostly bald knoll along the ridge at elevation 1,754 m.
Location: In the northern Oregon Cascades, approximately 6 miles east-southeast of Government Camp (as the crow flies), on the east side of the White River drainage within the Mount Hood National Forest, Hood River County.
Description: The Bonney Butte IBA is at the southern terminus of Surveyor’s Ridge, which originates near Hood River, Oregon, and extends southward for approximately 50 km to the southeast flank of Mt. Hood. Bonney Butte is a mostly bald knoll with a summit elevation of 1,754 m. The south and west slopes are steep, dropping approximately 725 m to the White River on the west and 65 m to Bonney Meadows on the east. The area within a 5-km radius of Bonney Butte is forested, except for Bonney Meadows and several clearcut tracts. Hemlock, true firs, and pines are common in the surrounding forests. Several huckleberry species also commonly occur in the area. The observation site is located on the highest point of the butte.
Ornithological Highlights: Bonney Butte has been a HawkWatch International monitoring location since 1994. Raptors are critical biological indicators of ecosystem health, and migration counts provide efficient, effective ways to collect valuable information and to provide for public learning opportunities. The season average for total raptors (1994-2001) is 2817 birds, though numbers range from 2,500 to 4,000 annually. The most numerous species observed are the Sharp-shinned Hawk, Red-tailed Hawk, Cooper's Hawk, Turkey Vulture, and Golden Eagle, with relatively high numbers of Merlins observed here. Up to 18 species of raptors have been documented in a single season. In 2010, observers counted 3390 birds across 52 observation days: 588 Red-tailed Hawk, 1,438 Sharp-shinned Hawk, 420 Cooper's Hawk, 446 Turkey Vulture, 47 Northern Goshawk, 80 Golden Eagle, 68 Bald Eagle, and 108 Merlin.

- Cape Blanco Nearshore Ocean
Off the coast of Cape Blanco, an area of nutrient-rich upwellings that supports a diverse community of marine life.
Location: Off the southern Oregon coast. This area changes in size and location due to seasonal and annual changes in wind and current patterns, but is generally located within 25 miles west of Cape Blanco and south up to 50 miles.
Description: This area has relatively consistent winds and a physical obstruction to ocean currents (Cape Blanco) that combine to create the most dependable and nutrient-rich upwellings away from the immediate coastline on the Oregon coast.
Ornithological Highlights: This area has some of the highest concentrations of seabirds in the California Current System (CCS). Because of the consistency of the upwelling at this site, the area may be particularly important during segments of climatic cycles when marine food resources are relatively scarce along the West Coast. Species found to rely on upwellings associated with the upper continental slope on this site include albatross and Sooty Shearwater.
For more information on Cape Blanco Nearshore Ocean, please see the Technical Site Report in the National IBA Database.

- Cascade-Siskiyou National Monument
CSNM IBA is a 53,000-acre BLM property in southwest Oregon (Jackson County) at the junction of the Cascade, Klamath and Siskiyou mountain ranges.
Location: In southwest Oregon at the junction of the southern Oregon Cascades and Siskiyou Mountains, southeast of the city of Ashland in southeast Jackson County.
Description: The Cascade-Siskiyou National Monument was established by Bill Clinton in June 2000 under the Antiquities Act. It was singled out as an "ecological wonder with spectacular biological diversity" in recognition of its role as a biological crossroads between the Cascade, Klamath/Siskiyou, and Great Basin ecoregions. It is the nation's first National Monument established specifically to protect biodiversity. The Monument is managed by the Medford District of the Bureau of Land Management as part of the National Landscape Conservation System. The BLM is currently developing its management plan for the Monument.
Outstanding Features: Two hundred and two bird species have been reported from the Monument. In addition to its importance to particular species of concern, including Northern Spotted Owl, Great Gray Owl, Peregrine Falcon, and Willow Flycatcher, the Monument is remarkable for the array of birds that are near their range limit in the area. This list includes northern limits of Blue-gray Gnatcatcher and California Towhee, western limits of Canyon Wren and Black-billed Magpie, eastern limits of Hermit Warbler and Band-tailed Pigeon, and southern limits of Ruffed Grouse and Rufous Hummingbird. The tremendous array of habitats in the Monument provide for great diversity in vertebrate fauna (Pepper Trail, Birds of the Cascade-Siskiyou National Monument).

- China Gulch
This valley in west-central Jackson County, Oregon is roughly 6,600 acres of chaparral with scattered small forest patches in generally south-facing drainages.
Location: Southwest Oregon, west-central Jackson County, just east of the town of Applegate and north of the Applegate River.
Description: Roughly 6,600 acres of chaparral, a high priority habitat in western Oregon lowlands and valleys where chaparral has been reduced for farming and grazing.
Ornithological Highlights: This IBA contains one of the largest remaining patches of chaparral in southwest Oregon, and hosts three bird species unique to this habitat: Blue-gray Gnatcatcher, Oak Titmouse, and California Towhee. Titmouse and Towhee are year-round residents here and the Gnatcatcher migrates from points south to breed here in the summer. The area also provides excellent winter cover and food resources for a diversity of birds year-round. During winter, manzanita provides a berry food source for several species, particularly Hermit Thrush. In early spring, manzanita flowers provide a nectar heavily used by arriving Rufous Hummingbird. The flowers are also eaten by Purple Finch and Golden-crowned Sparrow before and during spring migration.
Chaparral is a priority habitat in western Oregon lowlands & valleys, and has been reduced in extent in southwest Oregon through clearing for farming or grazing, overgrowth by trees due to fire suppression, clearing for development, and clearing to reduce fire hazard near developed areas.

- Cold Springs National Wildlife Refuge
Cold Springs NWR IBA is a 3,117-acre refuge east of Hermiston, Oregon, approximately 5 miles south of the Columbia River. The refuge includes a 1500-acre reservoir and surrounding marsh, diverse wetland habitats, cottonwood/willow riparian area, upland big sagebrush and native steppe grasses.
Location: Five miles south of the Columbia River and east of Hermiston, Umatilla County, Oregon.
Description: Cold springs NWR was established in 1909 as a preserve and breeding ground for native birds. The 3,117 acres of this refuge include and surround the 1,517-acre Cold Springs Reservoir. The remainder of the refuge consists of marsh, riparian, grassland, and sagebrush ecosystems.This is an overlay refuge: the Bureau of Reclamation manages the water in Cold Springs Reservoir for irrigation purposes and USFWS manages the surrounding habitat for migratory birds.
Ornithological Highlights: The refuge hosts thousands of wintering waterfowl: Mallard and Canada Geese are the dominant species, but good numbers of American Wigeon and Northern Pintail can often be found. A USFWS aerial survey in December 2002 yielded 10,740 Mallards, 3,010 Canada Geese, and 2,000 Northern Pintails. Green-winged Teal, Gadwall, Northern Shoveler, Redhead, Canvasback, Lesser Scaup, Common Merganser, Common Goldeneye, and Ring-necked Ducks are also common, though in smaller numbers. Small flocks of White-fronted Geese stop at Cold Springs during fall and spring migration. Tundra Swans can also been seen at Cold Springs. Hundreds of shorebirds can be seen during the fall migration when the upper reservoir is exposed. Counts have recorded up to 500 Western Sandpiper in August 2003 and 900 Killdeer in September 2003. Smaller numbers of shorebirds frequent Memorial Marsh during the spring migration.
Abundant wintering or migrant species include Orange-crowned Warbler, Yellow Warbler, Wilson's Warbler, Warbling Vireo, Ruby-crowned Kinglet, Hermit Thrush, Yellow-rumped Warbler, Oregon Junco, and White-crowned Sparrow.

- Columbia River Estuary
The Columbia River Estuary IBA runs from the Columbia River Plume in the Pacific Ocean to approximately river mile 60 at Crims Island (near Mayger, Oregon, and across from Stella, Washington).
Location: The Columbia River Estuary IBA runs from the Columbia River Plume to approximately river mile 60 at Crims Island (near Mayger, Oregon).
Description: The Columbia River Plume is a highly dynamic transition zone where freshwater from the Columbia River mixes with saltwater from the ocean. The summer plume generally pushes southward and occurs regularly offshore between Cape Meares, Oregon and Grays Harbor, Washington, while in winter it is regularly found northward and inshore (Guy, Zamon and Hunter, Jan 2008).
Ornithological Highlights: Annual seabird and marine mammal strip-transect counts have been conducted by NOAA Fisheries and OSU, and consistently record high numbers of seabirds using the area occupied by the Columbia River Plume. Strong salinity gradients are most often encountered at Willapa Bay, Columbia River, and Cape Meares. Sooty Shearwaters and Common Murres are the numerically dominant seabird species. California Gulls, Brown Pelicans, Caspian Terns, Heerman's Gulls, DC Cormorants, Pelagic Cormorants, and Brandt's Cormorants also use the areas in spring, summer and fall. Marbled Murrelet and Rhinoceros Auklet are occasionally observed in the plume. It is not uncommon to observe 1,000s to 10,000s of Sooty Shearwaters between April and September in the vicinity of the river mouth and plume. Common Murres, Double-crested Cormorants, Pacific Loons, Red-throated Loons, and Western Grebes also use the area and up to 1,000s. Other species documented in the estuary include: Bufflehead, Caspian Tern, Great Blue Heron, Long-billed Curlew, Pied-billed Grebe, Red-necked Grebe, Western Snowy Plover, and Virginia Rail. The western extent of the Columbia River Estuary IBA is a designated Western Hemisphere Shorebird Reserve Network site.
