Resource Management

Fire_512x219Refuge managers and wildlife biologists depend upon and utilize various tools to manage Caddo Lake National Wildlife Refuge for the benefit of wildlife.

Historically, the upland portions of the refuge were East Texas pineywoods that consisted of shortleaf pine and hardwoods such as southern red oak, post oak, white oak, mockernut hickory, white ash and other fire tolerant species. Wildfire was a frequent occurrence prior to European settlement. The Army reforested much of the open upland ground with loblolly pine. The refuge’s objective is to return the upland pineywoods on the refuge back to a fire tolerant pine savannah forest. The bottomland hardwood forest on the refuge was mostly undisturbed during the Army activities and is considered one of the best bottomland forests in Texas.

Currently, refuge staff are actively thinning around 500 acres per year and burning around 1,800 acres per year. The goal is to transition from a loblolly pine dominated forest that has a dense woody understory to a shortleaf pine dominated forest with an open grassy understory. Within 20 to 30 years, the refuge hopes this system will have returned to the state it was in before human settlement.

Another refuge management effort is to protect and restore habitat for bird species such as the red-headed woodpecker, eastern wood-pewee, loggerhead shrike, brown-headed nuthatch and Bachman’s sparrow. Red-cockaded woodpeckers are also known to use the open pine forest.

For the 1,000 acres of mature bottomland hardwood forests, the refuge is ensuring the succession of the old growth forest, allowing the development of large trees and other native trees and shrubs that support species such as Acadian flycatcher, warblers, pileated woodpecker, red-shouldered hawk and white-eyed vireo.
