The BBS is a point count based roadside monitoring program. Currently
there are over 4100 BBS routes scattered across the continental
U.S. and Canada.
Each roadside survey is approximately 24.5 miles (39.2 km) long
and comprised of 50 point counts spaced at 0.5-mile (800-m) intervals
to form a point count transect called a BBS route.
