The Development of Bird Conservation Regions

A mapping team comprised of members from the United States, Mexico, and

Canada assembled at the first international NABCI workshop held in Puebla, Mexico,

in November 1998, to develop a consistent spatial framework for bird conservation

for North America. After agreeing on general principles, they adopted a

hierarchical framework of nested ecological units delineated by the Commission for

Environmental Cooperation.

The team’s U.S. members met in December of that year in Memphis, Tennessee, to

apply the framework to the United States and develop a proposed map of BCRs.

The map and its BCR descriptions, along with an explanation of the ecological

framework and philosophy behind their development, was published in


A Proposed Framework for Delineating Ecologically-based Planning, Implementation, and Evaluation

Units for Cooperative Bird Conservation in the U.S.

This document was

widely distributed for review in March 1999. Shortly after the comment period

closed in October, the team evaluated the comments received and produced a

revised map. The map was presented to and approved by the U.S. NABCI Committee

during its November 1, 1999, meeting.

BCR 17 - Badlands and Prairies/Northern Great Plains Joint Venture

This semi-arid rolling plain is dominated by a mixed-grass prairie
that lies west and south of the glaciated Prairie Pothole region,
east of the Rocky Mountains, and north of the true shortgrass
prairie. Due in large part to the continued dominance of ranching
as a land use, many contiguous grassland tracts of significant size
persist in this area. As a result, this area is habitat for some of the
healthiest populations of high priority dry-grassland birds on the
continent, including Mountain Plover, McCown’s Longspur, and
Long-billed Curlew. The relatively small number of wetlands in
the region, including small impoundments created to serve as
livestock water sources, receives intensive use by upland nesting
waterfowl and broods.
