Small
Wetlands in the U.S. Prairie Pothole Region
Values Worth Conserving! |
The Facts
Prairie pothole
wetlands total 5.3 million acres in 2.7 million basins.
2.1 million basins,
containing 689, 000 acres, are less than 1 acre in size.
Small wetlands catch
runoff from snowmelt and rain. This is not flooding, this is downstream flood
prevention.
Each acre of small
wetland reduces flood damage to roads by $6.11 per year.
Each acre of small
wetland also provides $29.23 worth of flood damage protection to agricultural land per
year.
Wildlife Habitat
 |
 |
| Small wetlands, less than 1 acre in
size, are valuable wildlife habitat. Numerous small wetlands provide more habitat and
food for waterfowl than one large wetland of the same total acreage. Loss of these small
wetlands would have a significant impact on waterfowl migrating and breeding in the
Prairie Pothole Region. Wetland
easements and Partners for Fish and Wildlife agreements protect these important wetlands
on private land. Temporary and seasonal wetlands that go dry in spring or early summer
recycle nutrients, grow lush vegetation and fill with seasonal rains. They may be
cropped by farmers when conditions allow. |
