The Katy Prairie Conservancy (KPC) owns 13,000 acres of prairie, farmland, wetlands, and forest in Waller, Harris, and Fort Bend Counties. KPC also protects an additional 4,500 acres of land through cooperative agreements. The Katy Prairie is home to critically important prairie wetlands that are known for the great number of waterfowl that overwinter each year, including Snow and Greater White-fronted Geese, Blue-winged teal, and numerous shorebird species. Upland grasslands are home to Northern Bobwhite Quail, Eastern Meadowlarks, Flycatchers, coyote, bobcat, pocket gophers, bull snake, and other prairie species.

Nash Prairie (West Columbia, Texas)
Description: The Nash Prairie is co-owned by St. Mary's Episcopal Church and another entity. It is managed by a ranch manager who is paid by the estate and the major leasee. The ranch manager mows, hays and burns on his schedule. The Nash prairie is 350 acres and is 99% native; the ranch also has another "hay meadow" called the Notowy Prairie and it is 80 acres and its claim to fame is the silvanus dropseed which was thought to only grow in north Texas. To visit either prairie, call The Rev. Peter Conaty at St. Mary's (979-345-3456) or by e-mail at stmarys@hal-pc.org

Texas City Prairie Preserve - Nature Conservancy of Texas (Texas City, TX) website
The Texas City Prairie Preserve features rare coastal prairie habitat and is one of the last remaining sites that supports wild Attwater's prairie chickens. At the turn of the century, there were approximately 1 million Attwater's prairie chickens along the Texas coast. However, loss of coastal prairie habitat over the years devastated the population, and less than 50 remain in the wild today, making the bird one of the most endangered in North America. This preserve is situated on Galveston Bay in Texas City, approximately 40 miles south of Houston and protects 2,303 acres.
