Land Conservation

alt

Green Spaces Alliance of South Texas, founded as Bexar Land Trust in 1998, focuses our land conservation activities in the Southern Edwards Aquifer region and the San Antonio and Nueces River basins. Our mission is to sustain the natural environment and enhance urban space through land conservation, community engagement, and education. In San Antonio, we foster community gardens and a youth nature photography program.

1 copyAs a local land trust, our landowner relationships emphasize accurate information about land conservation and available options to achieve long-term goals for ecologically healthy properties, preserving family heritage, potential economic benefits, and evaluating natural resource management practices. Since 2000, we have been part of a team that has negotiated conservation easements in Bexar, Medina, and Uvalde counties through the City of San Antonio’s Edwards Aquifer Protection Program, which has resulted in over 135,000 acres of conserved land over the critical Edwards Aquifer Recharge and Drainage Zones.

Preserving our lands for the future

Bulverde Oaks

Bulverde Oaks was gifted to Green Spaces Alliance in 2010. It is approximately 31 acres within San Antonio city limits, located on the corner of Judson Road and Loop 1604, on the far Northeast side. It is a special property due to its location and proximity to the Edwards Aquifer Recharge Zone. It sits on the Artesian Zone of the Edwards Aquifer and drains directly into the Recharge Zone. Greater than 50% of the parcel is within the 100-yr floodplain and exhibits many wetland features. This island of undeveloped acreage is a sanctuary for local wildlife and native plants. When visiting the property, more often than not, a person may see a wild hog, a white-tailed deer, mallard ducks, wild turkeys or any number of other endemic birds and mammals.

Historically this land was used for ranching, but pressure to develop the land into a quarry has increased with urban sprawl. With most of the property in the floodplain, these pressures are reduced to some extent. Now that Bulverde Oaks is owned and managed by GSA, those pressures have been alleviated and the undeveloped island can continue to thrive.

The photograph below shows a retention pond built over 50 years ago for livestock ventures. Today it is a lovely sanctuary for migratory water fowl and wetland plant species. This stock tank has standing water even in periods of intermediate drought, serving as a life-sustaining, natural resource for all creatures in the area.

The long-range plan for Bulverde Oaks includes construction of up to two miles of walking trails, with education stations and wildlife viewing points at ecologically important locations. Wildlife and vegetative management will also require some attention. Some unwanted plant and animal pests will be managed while promoting desired native species. Already on site are a bird blind at the pond, a bat house in a savannah capable of housing up to 400 bats, and a bee hive sanctuary for rescued honey bees.
