Gulf Prairies (Lower Coast) Ecoregion
Wildlife Management Plan for Kenedy County, Texas
Kenedy County spans the boundary between the Southern Texas Plains and Western Gulf Coastal Plain, supporting an exceptional diversity of 154 documented wildlife species.
Intelligence Snapshot
Regulatory Complexity
Kenedy County's conservation obligations require careful attention to how management practices affect listed species habitat. The 5 endangered species documented here mean that brush clearing, water development, and land use changes carry ESA compliance risk. A properly calibrated plan accounts for these constraints. A generic plan does not.
Kenedy County Ecological Profile
Kenedy County's 1,459 square miles of coastal grasslands, marshes, and tidal flats support 154 documented wildlife species, placing it among the more biologically diverse counties in the Gulf Prairies (Lower Coast) region. This region receives 35 to 55 inches of rainfall annually and is shaped by hurricanes, tropical storms, and the seasonal rhythms of migratory waterfowl moving along the Central Flyway. The lower coast's thornscrub and coastal marsh system is critical habitat for ocelot, jaguarundi, and nesting sea turtles. Brush corridor retention and beach management are priority management actions distinct from the upper coast.
Wildlife management on the Gulf Prairies emphasizes wetland management, coastal prairie restoration, and moist soil management for waterfowl and shorebirds. Properties with access to water control structures can manage shallow impoundments on seasonal schedules: drawing down in spring to stimulate smartweed, barnyard grass, and other moist soil plants, then reflooding in autumn to create feeding habitat for migrating waterfowl. Upland prairie management focuses on prescribed fire at 2 to 3 year intervals to control Chinese tallow, McCartney rose, and other invasive woody species while stimulating gulf muhly, little bluestem, and brownseed paspalum. Grazing management using short-duration, high-intensity rotational systems can mimic the disturbance patterns of historic bison herds and maintain the structural diversity that grassland birds require.
Transitional Ecoregion
Kenedy County spans the boundary between the Southern Texas Plains and Western Gulf Coastal Plain. Species assemblages, soil types, and appropriate management intensities differ between these regions. A property in the Southern Texas Plains portion of the county will require different practices than one in the Western Gulf Coastal Plain zone.
Soil Conditions
Soils are heavy, poorly drained clays of the Lake Charles, Beaumont, and Edna series, underlain by a shallow water table that creates the seasonal wetland conditions critical for waterfowl and shorebird habitat.
Fire Ecology
Coastal prairie evolved with fire at 1 to 3 year intervals. Prescribed burning is the primary tool for controlling Chinese tallow invasion and maintaining the native grass and forb communities that support Attwater's prairie chicken and other grassland obligate species.
Spans 2 ecoregions: Southern Texas Plains, Western Gulf Coastal Plain
This region is the last stronghold of the Attwater's prairie chicken, one of the most endangered birds in North America, with fewer than 200 individuals surviving in the wild. Mottled duck, a non-migratory species endemic to the Gulf Coast, depends on the mosaic of coastal prairie and freshwater wetlands for nesting and brood-rearing. Wintering waterfowl concentrations in the rice prairies and managed wetlands can exceed a million birds, including pintail, teal, and white-fronted geese. Whooping crane, the tallest North American bird and a federally endangered species, winters at Aransas National Wildlife Refuge and feeds in the surrounding marshes and grain fields.
Kenedy County Species of Conservation Concern
TPWD records document 154 species across 8 taxonomic groups in Kenedy County, placing it among the most biologically rich counties in Texas. Birds (42 species) and Mammals (36 species) represent the deepest inventories. The county carries significant conservation obligations: 5 federally endangered species, 7 federally threatened, and USFWS critical habitat designations for 1 species. Management activities on private land must be designed to avoid incidental take. Federally listed species include northern aplomado falcon, whooping crane, and ocelot. Northern aplomado falcon: Requires open grassland with scattered yucca or shrub for nesting in South Texas.
Primary Management Targets
mottled duck, whooping crane, reddish egret
Listed Species
Requires open grassland with scattered yucca or shrub for nesting in South Texas. Brush encroachment control and grassland restoration benefit this species. Reintroduction efforts are active along the lower Texas coast.

Gulf Prairies (Lower Coast) Wildlife Management Standards
Management in Kenedy County is driven by water. Seasonal wetland drawdown and reflooding schedules, Chinese tallow control, and coastal prairie fire are the primary management activities. Under 34 TAC Section 9.2002, the Gulf Prairies (Lower Coast) ecoregion requires 15 to 20 minimum acres, 10% brush management coverage, and semi-annual wildlife census documentation. Primary targets are mottled duck, whooping crane, and reddish egret. Wetland water level management and coastal prairie fire are the dominant management tools.
These are the intensity thresholds your plan must meet for the Gulf Prairies (Lower Coast) ecoregion. Your county appraisal district will verify compliance against these minimums. A plan that does not address them risks denial of your wildlife management valuation. For a complete overview of the seven management pillars, see the management pillars guide.
This is a hard minimum. The appraisal district will verify that your plan prescribes brush management on at least this proportion of your acreage annually.
Food plots must provide nutritional supplementation for target species. The minimum size and density are set by ecoregion to reflect carrying capacity.
Feeder placement and protein content are auditable. The aflatoxin threshold (20 ppb) is a compliance requirement, not a suggestion.
Fire ant suppression directly supports native harvester ant populations, the primary food source for Texas horned lizard and other ground-foraging species.
Brown-headed cowbirds are brood parasites that reduce nesting success of songbirds. The minimum applies to properties where cowbird trapping is selected as a management activity.
The burn rotation percentage applies over the full plan period. Properties that cannot burn due to WUI constraints must document the limitation and substitute equivalent mechanical treatment.
Nest box density is based on territory size of target cavity-nesting species. Boxes must be monitored and maintained annually.
