Texas Land Conservancy (TLC) gives these reasons:
* To protect native wildlife and plants and to conserve the landscapes that have been important to Texans for generations.
* To document a natural history of the land as benchmarks for future generations.
* To save critical lands which are crucial for environmental functions such as clean air, erosion control, clean water, and wetlands protection.
* To function as biological reserves where our dwindling genetic stock will be preserved in perpetuity.
* To conserve open space and reduce the negative effects of land fragmentation.
* To provide scientific research opportunities and serve as living classrooms where people can observe and appreciate nature.
* To preserve above all the natural diversity essential to the continued health and survival of the environment we all share.
