Preplanting Site Treatments and Natural Invasion of Tree Species onto Former Agricultural Fields at the Tensas River National Wildlife Refuge, Louisiana

As part of a study of oak planting techniques for bottomland hardwood afforestation we examined the natural invasion of woody species onto former agricultural fields at Tensas River National Wildlife Refuge. Three replications of 14 treatments were established as 0.4 hectare (1 acre) plots in a complete randomized block design. Combinations of these treatments were used to examine the effects o...

Sediment quality in freshwater impoundments at Savannah National Wildlife Refuge.

Freshwater impoundments at Savannah National Wildlife Refuge (NWR), South Carolina, provide an important habitat for wildlife species, but degraded sediment quality in the Savannah River downstream of the discharge from two impoundments have caused concern about potential contaminant problems within the impoundments.

U.S. Fish & Wildlife Service Contaminants as Contributing Factors to Wood Frog Abnormalities on the Kenai National Wildlife Refuge, Alaska

Deformed amphibians have been observed in the Kenai National Wildlife Refuge, Alaska. Environmental variables such as contaminants, ultraviolet radiation [UV], or parasites may cause deformities. It is important to identify the environmental cause of deformities in order that effective management strategies can be implemented to enable the recovery of affected populations. To determine whether ...

Climate change adaptation for the US National Wildlife Refuge System.

Since its establishment in 1903, the National Wildlife Refuge System (NWRS) has grown to 635 units and 37 Wetland Management Districts in the United States and its territories.
