Friends of the Bracken Bat Cave can breathe a little easier today, now that a threatened encroachment by a high-density housing development is officially over.

That's because the real estate deal closed Friday, transferring the land from Galo Properties to the Nature Conservancy.

Defendants of the Bracken Cave have been working on this deal for more than a year.  The effort was spearheaded by San Antonio City Councilman Ron Nirenberg, who took up the challenge to visit the cave right after he was elected in 2013.

San Antonio City Councilman Ron Nirenberg announced an agreement last week to protect the world’s largest bat cave from encroachment by future development.

The city will join with several other entities to turn the 1,500-acre property, known as Crescent Hills, into a conservation easement that will permanently protect the area’s natural resources.

The San Antonio River Authority is again offering its bat educational program on the Museum Reach to raise awareness about the bats’ relationship to our environment. 

This is the SARA’s fifth year for "Bat Loco," an informational program that coincides with the bats’ colonization after their return to South Texas from Mexico.

The future of the Bracken Bat cave is far from resolved. The cave, which has the largest maternal bat colony in the world, made news last summer when Galo Properties announced a planned housing development near the cave. The announcement caused an uproar from both water conservation and bat advocates.

After their winter trip south, Mexican free-tailed bats are returning to the Bracken Bat Cave in Central Texas in larger numbers, which is good news for South Texas agriculture.

Millions of Mexican free-tailed bats make their summer home at the Bracken Cave just north of San Antonio, and farmers in South Texas rely on them to swarm across their farmland and eat the insects that can destroy crops.
