Roanoke River Bottomlands
Location: Martin, Halifax, Bertie and Northampton Counties
Total Size: 133,108 acres
Map
Site Description: This vast IBA begins near the small community of
Weldon and continues downriver more than 100 miles to Albemarle Sound. The
bottomland hardwood forest stretches nearly 5 miles wide in places and is the
best example of this habitat type in North Carolina. The site abounds with
birds and other wildlife.
Habitats: bottomland hardwood forest, river
The bottomland hardwood forest is extensive and is dominated by bald cypress and
water tupelo along the lower reaches of the river and mixed bottomland hardwood
species in other areas.
Land Use: Wildlife conservation, other conservation, recreation, hunting, fishing
Primary Threats: regulated water flow, logging
Protection Status: About 51,000 acres of the site is protected and
managed by both public and private groups including the US Fish and Wildlife
Service, NC Wildlife Resources Commission and The Nature Conservancy. The remaining acreage
is in private ownership.
Conservation Issues: The potential impact of regulated water flows on
aquatic life downriver is a significant concern, but very little is known.
Logging is also a concern as a major timber company has significant holdings in
the area. Lastly, industrial development along the river and associated
activities could threaten the entire system if permitted.
Birds: With 214 bird species recorded, 88 of which are known to breed, this
site is one of the most diverse in the coastal plain. Forty-four species
of neotropical migrants are known to breed within the site. Several colonies
of wading birds are present, including the Conine Island colony, which is North
Carolina's largest inland colony of wading birds (Criteria 4f). The site supports a
significant diversity and abundance of Neotropical migrant songbirds (Criteria
4g), as well as
a large number of breeding wood ducks. The site holds a significant diversity and abundance of species associated with
bottomland hardwood forests (Criteria 3).
