- Wildlife Management
LLELA is charged with protecting the native plants and animals that call these lands home.
Only tiny islands of native North Texas Prairie remain! Work has begun to preserve what is left and restore what was lost.
- Bottomland Forests & Cross Timbers
Much like the other ecosystems of north central Texas, our forests have been decimated and fragmented, with only a few small and isolated patches of old growth left scattered amongst the younger forests of the floodplains.
- Aquatic Habitats
Like much of North Texas, LLELA is host to a variety of aquatic systems, from the perennial Elm Fork of the Trinity River, to lakes, former stock ponds, and prairie potholes; from intermittent creeks and streams such as Office Creek, to traditional emergent wetlands such as the Cottonwood Marsh.

- Prescribed Fire
Research and training in the use of prescribed fire in prairie restoration.
- Wetland Ecology
Research in constructed and natural wetlands.
- Prairie Ecology
Research in bison reintroduction and management techniques.
- Research Notes Series
- Graduate theses and dissertations
The bison herd has been moved to a new home on private land. Moving the herd will allow our restored prairie areas a chance to recover from last summer's severe drought and from previous grazing. We hope to have bison roaming on our prairie again in the future. Please call 972-219-3930 if you need further information.
Before the pioneer movement, healthy North Texas prairies were dominated by little bluestem, big bluestem, sideoats grama, indiangrass, and buffalo grass.
- Invasive Species
Controlling invasive plant and animal species is LLELA’s greatest management challenge.
Putting back the missing pieces of our ecosystems.
