Other Joint Ventures
Prairie Pothole Joint Venture - www.ppjv.org
The Prairie Pothole Joint Venture (PPJV) region includes the United States portion of the Prairie Pothole Region, which contains millions of glacially created wetlands embedded within a matrix of agriculture and grasslands. It stretches from the northern half of Montana through the Dakotas and into Minnesota and Iowa, where it borders the UMRLGRJV region. Despite significant degradation and loss of bird habitat, the region continues to support an incredible abundance and diversity of breeding wetland and grassland birds. The Prairie Pothole Region (2/3 of which is in Canada) has the highest concentrations and is the most important area for breeding waterfowl on the continent.
Central Hardwoods Joint Venture - www.chjv.org
The Central Hardwoods Joint Venture (CHJV) region, located along the southern border of the UMRGLRJV region, contains portions of Oklahoma, Arkansas, and Missouri in the western portion (Ozark Plateau), and Illinois, Kentucky, Tennessee, and Alabama in the eastern portion (the Interior Low Plateau). Oak and pine woodlands and savannas were the dominant natural community throughout most of the Ozarks/Ouachitas, along with a transitional zone of tallgrass prairie along the northwestern border. The Interior Low Plateau was historically dominated by oak and mixed forests. The CHJV region contains some of the largest unfragmented blocks of forest in the Midwest, supporting source populations of many priority forest interior bird species.
Lower Mississippi Valley Joint Venture - www.lmvjv.org
The Lower Mississippi Valley Joint Venture (LMVJV) region includes BCR 26 (Mississippi Alluvial Valley) in the east and BCR 25 (West Gulf Coastal Plain/Ouachitas) in the west. The LMVJV region extends from southeastern Missouri along the Mississippi River floodplain through east Arkansas and western Mississippi to the Gulf of Mexico in southeastern Louisiana; it then extends west through Louisiana to eastern Texas, and back north through southeastern Oklahoma and Arkansas. Small portions of Kentucky and Tennessee also intersect with the JV regional boundary. BCR 26 was once covered by bottomland hardwood forest but today more than 80% has been cleared for agriculture and other uses, and the hydrology has been extensively altered. Despite these changes, the BCR still supports huge numbers of migrating and wintering waterfowl and shorebirds. BCR 26 is, in general, dominated by pine woodlands in the uplands and bottomland hardwoods in lowlands. Pine woodlands have been altered by unrestricted logging in the early 20th century, combined with fire suppression in recent decades. Tree species composition has changed in many areas from longleaf and shortleaf pine to loblolly and slash pines, often managed in short-rotation plantations. These stands are often not suitable for many pine savanna/woodland birds, such as Red-cockaded Woodpecker and Bachman’s Sparrow.
Appalachian Mountains Joint Venture - www.amjv.org
The boundaries of the Appalachian Mountains Joint Venture (AMJV) region closely follow that of BCR 28 (Appalachian Mountains). The AMJV stretches along the Appalachian Mountain chain from southern New York to northern Alabama, including southeastern Ohio, where it borders the UMRGLRJV region. The predominantly rugged, mountainous terrain is dominated by forest communities of oak-hickory at lower elevations and coniferous forests at higher elevations. Forest, woodland, and early successional forest/shrub species are the primary focus of this JV’s conservation efforts. However, the AMJV does include the headwaters of several major eastern rivers and their associated wetlands, which support waterfowl, shorebirds, and waterbirds during migration. Flatter areas associated with agriculture and mining also provide some habitat for grassland species, such as Henslow’s Sparrow.
