Strategies for Protecting the Edwards Aquifer

Two million people – from Central to Southwest Texas – depend on the Edwards Aquifer for their drinking water.

It also supplies important water sources for industry, agriculture, recreation…a number of things.

Cindy Loeffler, water resources branch chief at Texas Parks and Wildlife, says eight federally listed endangered species call the aquifer home; some of them exist in this location only. The Edwards Aquifer Habitat Conservation Plan intends to protect them, and allow Texans’ continued use of the shared resource by implementing a mixture of strategies.

Water conservation is a key part of it…but also [part of it is] looking at different ways to manage water. For example, we do currently have different levels of conservation that kick in to action as drought increases, but also many measures to help make the ecosystems more resilient. Things like removing non-native species, [and] helping to restore habitat that’s been compromised. One notable thing, especially for folks who recreate on the San Marcos River that’s been done, is to create a state scientific area that makes it unlawful to uproot Texas Wild Rice, a federally protected plant.

It is easy to be dismissive of a plan to protect species which exist in very small numbers or that we do not often see. Tomorrow we talk about the value of these species.

Maintaining Ecosystem Balance

An ecosystem is a complex set of interrelationships among plants, animals, microorganisms, land, and water. And Texas Parks and Wildlife is a collaborator on a conservation plan to protect a special ecosystem: the Southern Edwards Aquifer.

The Edwards aquifer is home to many, many rare species, including eight federally listed threatened and endangered species.

Cindy Loeffler is water resources branch chief at Texas Parks and Wildlife.

Some of the most visible endangered species associated with the Edwards Aquifer are Texas Wild Rice – it’s only found in the upper two miles of the San Marcos River. Also, [of importance are] fountain darters, small fish that are found in the San Marcos River and the Comal River, and a number of cave-dwelling species you might not see just recreating in the rivers – but they’re there.

Loeffler worked on the Edwards Aquifer Habitat Conservation Plan. Some of the species she mentioned are unique to the Edwards Aquifer Ecosystem.

It’s important to protect these species for that reason, but also, this is a major water supply for many of us here in Texas, so finding a way to share that resource –finding the proper balance – that’s what the Edwards Aquifer Recovery Implementation Program has been about.

What’s in the plan to help protect endangered species? We look at that tomorrow.

TPW Magazine: Wind and Wildlife

Texas is the number-one wind energy state; but what’s the effect of wind farms on bats and birds? Writer Russel Roe addresses this matter in an article for the March issue of Texas Parks and Wildlife magazine.

The stakes are high when it comes to wind and wildlife, especially as you consider that Texas has the largest population of bats in the world and the nation’s highest diversity of bird species.

Although clean, renewable wind energy offers benefits to the environment, you’ll learn in Roe’s article that it does so at the cost to wildlife. Hundreds of thousands of birds and bats die annually, their fates sealed when they fly into the turning blades of gargantuan turbines.

Bats are hardest hit—no pun intended. With more than twice the number of fatalities than birds.

Roe writes that wind companies and conservation groups agree that responsible siting of wind turbines away from areas with high wildlife activity is a key first step to reducing the problem. TPWD is working on its own set of wind energy guidelines and hopes to release them sometime in 2019.

Meanwhile, read Russel Roe’s article about Wind and Wildlife in the March issue of Texas parks and Wildlife Magazine. You’ll also learn about research on ultrasonic acoustic deterrents that reduced bat fatalities by 46 percent.

TPWD Kills and Spills Team

If thousands of fish were to wash up dead on the Texas coast, biologists from Texas Parks and Wildlife Department’s Kills and Spills Team would be dispatched to the scene.

The Kills and Spills Team is a program in the Resource Protection division of the department, and is responsible for responding to fish kills, wildlife kills, oil spills and hazardous chemical spills. The goal is to protect fish and wildlife from impacts caused by man-made pollution

While large fish kills attract the most attention, uncovering sources of ongoing low-level pollution is just as important.

Some of the most common fish kills that occur near communities are often small—sometimes associated with leaking sewer lines or overflowing manholes. These are segments of the waste-water collection and transport system that can fail. But not all fish kills are caused by pollution. It’s not uncommon to see dead fish when temperatures suddenly drop. Although the majority of fish kills we see are due to natural causes, pollution may be a factor.

TPWD encourages the public to call anytime it sees dead fish in the water and along shorelines. Doing so allows the agency to send out biologists to assess the situation.

TPW TV: Black Capped Vireo

In the Texas Hill Country, biologists are keeping track of a Texas treasure: the Black Capped Vireo.

I stop in my tracks every time I hear one [vireo] Up…there’s that bird. Right there!

Jeff Foreman is a Wildlife Biologist at Mason Mountain WMA. For many years the black cap was an endangered species, but over the past 30 years this little bird has made a big comeback.

Healthy nesting habitat is very much required for the vireo’s sustainability. They really like these low shrubs with spaces in between. They can fly in and around and catch insects.

Historically vireos thrived in the scattered shrubs and open grassland that stretched across Central Texas. But with European settlement came grazing by cattle, goats and sheep.

…sometimes the populations of those livestock weren’t kept in check. They just ate the homes out from under the vireo.

Fire suppression, white-tailed deer, and the brown-headed cowbird, also played parts in reducing the vireo’s population. It was listed in endangered 1987. The good news is, it was delisted in April of last year.

Find out how biologists worked this magic the week of January 27 on the TPW TV series on PBS. Check your local listings.
