Enhancing Rainwater for Native Plants on an Austin Preserve

Some people think I, as president, do nothing in CAMN but send emails and run some meetings. Today I offer a spot of proof to prove otherwise. I was photographed in the wild at a work session on Austin Water/Wildland Conservation Division’s Vireo Preserve at the completion of one of the last steps of finishing our rainwater collection system. This remote-canyon roof structure will help free volunteers from having to haul water a quarter-mile each week over narrow trails to a staging area known as “Terry Town” (after longtime Wildland volunteer, Terry Southwell—also from the CAMN class of 2013.) The water is used, mostly by Terry, to help get newly-planted native forbs, grasses and shrubs established. While the property does feature a spring that runs most of the year, volunteers take great pains to avoid disturbing its natural flow and the plants and wildlife that have become established around them.

The last remaining step in the all-volunteer construction project will involve running PVC pipes from the downspout to the first tank, adding overflows, and attaching spigots. Then, the process can be turned over to the whims of Central Texas weather. The roof, at 128 square feet, will collect enough water to fill the two tanks after 4 inches of rain.

And, if you’re interested in some of the fun projects Wildland Conservation and Austin Water dream up to help protect critical habitat for endangered species, and the water quality of our local segment of the Edwards Aquifer, please see http://austintexas.gov/department/wildland-conservation-division Members of the public can sign up for guided hikes on protected preserves, or volunteer to help in a wide array of conservation efforts, from public outreach to land stewardship.
