Rolling Plains Ecoregion
Wildlife Management Plan for Concho County, Texas
Concho County spans the boundary between the Central Great Plains and Edwards Plateau, with 55 documented wildlife species.
Intelligence Snapshot
Regulatory Complexity
Concho County's conservation obligations require careful attention to how management practices affect listed species habitat. Critical habitat has been designated for 4 species within county boundaries. Federal review may be triggered by land use changes in designated areas. A properly calibrated plan accounts for these constraints. A generic plan does not.
Concho County Ecological Profile
The Rolling Plains of north-central and western Texas is a transitional landscape of mesquite-grassland, eroded redbed canyons, and brushy draws, positioned between the High Plains caprock to the west and the Cross Timbers to the east. Concho County's 984 square miles are characteristic of this landscape. This is classic quail country: mixed-grass prairie interspersed with shin oak mottes, lotebush thickets, and sand plum patches that provide the ground-level structure bobwhite and scaled quail need for nesting, brood-rearing, and escape cover. This is quail country. The mixed-grass prairie and brushy draws support some of the most productive wild bobwhite populations remaining in North America, but maintaining that productivity requires active brush management and prescribed fire.
Brush management on the Rolling Plains is a balancing act between reducing mesquite canopy cover to restore grass production and retaining enough woody structure to provide wildlife cover. The standard approach combines aerial herbicide application on dense mesquite flats with mechanical treatment of regrowth, followed by prescribed fire to maintain the treated areas. Strip-pattern treatment, alternating cleared and untreated bands, creates the habitat mosaic that bobwhite quail populations require: open grassland for foraging and nesting within short flight distance of woody escape cover. Prickly pear management is increasingly important as cactus density has increased under decades of overgrazing and fire suppression. Half-cutting or targeted herbicide application reduces prickly pear while maintaining some plants for the moisture and fruit they provide to wildlife during drought.
Transitional Ecoregion
Concho County spans the boundary between the Central Great Plains and Edwards Plateau. Species assemblages, soil types, and appropriate management intensities differ between these regions. A property in the Central Great Plains portion of the county will require different practices than one in the Edwards Plateau zone.
Soil Conditions
Soils are diverse, ranging from deep red sandy loams of the Miles and Springer series on uplands to heavy Stamford and Rowena clays in bottomlands, with shallow, rocky Rough Break soils along canyon escarpments.
Fire Ecology
Fire historically burned the Rolling Plains at 3 to 7 year intervals, maintaining open grasslands and limiting mesquite and cactus density. Prescribed fire is critical for post-treatment maintenance of brush-managed areas and for stimulating native forbs that provide quail food.
Spans 2 ecoregions: Central Great Plains, Edwards Plateau
Northern bobwhite quail is the primary management target on Rolling Plains ranches, and the region supports some of the most productive wild quail populations remaining in the United States. Scaled quail occupy the drier, more open western portions. Texas horned lizard is a species of high conservation concern that has declined across much of its range due to red imported fire ant invasion and loss of harvester ant prey. Lesser prairie chicken occurs in the sandy, shinnery oak rangelands of the western Rolling Plains. Raptor diversity is high, with golden eagle, ferruginous hawk, and Mississippi kite all nesting in the region.
Concho County Species of Conservation Concern
TPWD records 55 species in Concho County. Birds represent the most documented group at 22 species. The county carries significant conservation obligations: 2 federally endangered species, 2 federally threatened, and USFWS critical habitat designations for 4 species. Management activities on private land must be designed to avoid incidental take. Federally listed species include Texas fatmucket and Texas pimpleback. Texas fatmucket: Freshwater mussel endemic to central Texas rivers.
Primary Management Targets
bobwhite quail, lesser prairie-chicken, white-tailed deer
Listed Species
Freshwater mussel endemic to central Texas rivers. Sedimentation from land clearing, impoundment, and water quality degradation are primary threats. Riparian buffers and erosion control benefit this species.
Freshwater mussel in central Texas rivers. Threats include impoundment, water quality degradation, and altered flow regimes. Riparian management and erosion control are beneficial.
Western distinct population segment is threatened. Requires large patches of mature riparian woodland (cottonwood, willow) with dense understory. Clearing riparian corridors wider than 300 feet may trigger consultation in designated critical habitat.
Freshwater mussel found in central and East Texas rivers. Sensitive to sedimentation, flow alteration, and water quality changes. Maintaining riparian vegetation and minimizing erosion are key management practices.

Depends on harvester ant colonies for food. Fire ant suppression and native grassland restoration directly benefit this species. Listed as state threatened.

Rolling Plains Wildlife Management Standards
In Concho County, the management balance is mesquite canopy reduction for grass production against retaining enough woody cover for quail escape habitat. Strip pattern treatment is the standard approach. Under 34 TAC Section 9.2002, the Rolling Plains ecoregion requires 20 to 30 minimum acres, 15% brush management coverage, and annual wildlife census documentation. Primary targets are bobwhite quail, lesser prairie-chicken, and white-tailed deer. Management prescriptions emphasize maintaining large, connected tracts of native rangeland with minimal fencing.
These are the intensity thresholds your plan must meet for the Rolling Plains 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.
In Concho County, brush management targets mesquite canopy reduction while retaining enough woody cover for wildlife escape habitat.
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.

Water Resources
3 Groundwater Conservation Districts regulate water resources in the county, with permitting requirements for new wells and production limits that affect agricultural and wildlife management water sources.
Infrastructure
The Railroad Commission documents 2,746 wells and 180 pipeline segments in Concho County, a moderate industrial presence alongside agricultural land use. Historical exploration accounts for the majority of the well record, with dry holes at 55% of all documented wells. 3 orphan wells are on the Railroad Commission's plugging priority list.
With 2 federally endangered species, Concho County is not a place for guesswork in wildlife management planning.
