Natural Resources Overview

In addition to managing the unique water resource and its associated hydrological and recreational resources, Town Bluff Corps personnel manage numerous other natural resources: forests, wildlife, and cultural, to name a few.
The management of non-water related resources must of course depend upon associated vegetation.

At Town Bluff the typical East Texas Pineywoods cover types abound, including pine uplands, terraces, and lowlands, bottomland hardwood, pine-hardwood mixtures, and occasional open areas supporting native and introduced grasses. However, because this is a man-made reservoir, some of the naturally occurring ecosystems and their associated cover types are changing somewhat. In any case, great diversity of biological communities exist. This fact is especially evident in the abundance of vegetative types. Lowlands contain aquatic grasses, buttonbush, elm, sycamore, sugarberry, baldcypress, overcup oak, tupelo, water hickory, green ash, swamp chestnut oak, and sweetgum. Terrace lands support loblolly pine, blackgum, beech, magnolia, holly, sweetgum, red oak group, white oak group, and various hickory species.

Upland types predominantly consist of loblolly pine, along with occasional upland oak and hickory species mixed in. A few high, sandy areas that were devastated by Hurricane Rita have recently been planted to longleaf pine.  Shrub species include yaupon, waxmyrtle, dogwood, sparkleberry, and various viburnum and hawthorn species. Grass species found in open areas include bluestem, bermuda, and introduced Pensacola Bahia Grass. Shrubs, dewberry, blackberry, greenbriar, and various vine species proliferate around edges of fields or openings created by blowdowns or Southern Pine Beetle infestations. In summary, lands lying above the normal reservoir pool level are predominately forested and are managed accordingly.

Wildlife Management at Town Bluff is accomplished largely by management of the forest resources. Neither one is undertaken without consideration for the effects upon the other. If done correctly, both forest and wildlife resources benefit from prescribed management actions. As a general rule mixed vegetative cover is more beneficial for most wildlife species than are the more homogenous cover types. Therefore management activities are almost always planned with greater diversity as a goal. 

Wildlife species prevalent at Town Bluff include white-tailed deer, gray squirrel, fox squirrel, swamp rabbit, and cottontail rabbit. Fur bearers include otter, mink, raccoon, bobcat, red fox, gray fox, opossum, nutria, beaver, and eastern skunk. Upland game birds include Northern Bobwhite, mourning dove, wild turkey, and American wood cock. Numerous species of ducks and geese also frequent the habitat at Town Bluff. Among these are: mallard, wood duck, American widgeon, gadwall, pintail, blue and green-winged teal, scaup, redhead, canvas back, ring-billed duck, Canada geese, snow geese, and blue geese.

Non-game birds include warblers, hawks, bald eagle, osprey, herons, egrets, sandpipers, owls, sparrows, finches, flycatchers, vultures, crows, woodpeckers, and common loon. Several poisonous snakes should also be mentioned, although the only active management performed on their behalf is avoidance! These are coral, timber rattlesnake, pygmy rattlesnake, cottonmouth, and copperhead. Town Bluff also supports a thriving, huntable population of American alligators.

National Park Service - Big Thicket National Preserve

The River Corridor Unit of the preserve joins the southernmost boundary of the project.  Mutual assistance and information exchange between the Corps and the NPS is excellent.  The agency maintains a radio and antenna in the project radio building and tower.  Recreational data and statistics are interchanged annually and each agency furnishes literature to the other for public distribution.  Mutual surveillance is conducted for the security of public lands.
