Resource Management

Mallard drake / USFWS

Grulla National Wildlife Refuge actively manages these lands for the benefit of wildlife.


The refuge conducts seasonal surveys on lesser prairie chickens, sandhill cranes, and waterfowl. These surveys are used to gauge populations, habitat use and ultimately help the U.S. Fish and Wildlife determine habitat needs and management issues affecting waterfowl and other migratory birds. Another important management tool is the installation and management of water guzzlers. These sources of water become increasingly important for wildlife whose options have become limited due to loss of habitat, including historic sources of water. The refuge has installed and maintains these guzzlers for a diversity of wildlife.
