Resource Management

resource management 340x219


We are committed to preserving the natural resources of the ACE Basin so that all the habitats and wildlife continue to thrive. We do this mostly through "moist soil management" and prescribed burning and disking.

Moist soil management is a technique that promotes growth of wetland plants, insects, crustaceans, and small fish by mimicking the natural wet and dry season cycles. The most important tool in this process are the rice field trunks (pictured above), which are used to control water flow between tidal creeks or rivers and the managed wetland areas (also called "impoundments"). 

First used in the 1700s on rice plantations, trunks still remain the most effective and economical water control structures. They operate on tidal surge and consist of wooden culverts with flap gates. 

Fire

We also perform prescribed fires (controlled fires to lower chances of wildfires) and disking, a process of cutting the land so undergrowth doesn't hinder wildlife movement or growth, on certain abandoned fields to encourage habitat diversity.

Trapping Occurs on this Refuge

Trapping is a wildlife management tool used on some national wildlife refuges. Trapping may be used to protect endangered and threatened species or migratory birds or to control certain wildlife populations. The U.S. Fish and Wildlife Service also views trapping as a legitimate recreational and economic activity when there are harvestable surpluses of fur-bearing mammals. Outside of Alaska, refuges that permit trapping as a recreational use may require trappers to obtain a refuge special use permit. Signs are posted on refuges where trapping occurs. Contact the refuge manager for specific regulations.Click here for more information on trapping within the National Wildlife Refuge System.
