Saving water and lush landscapes aren’t mutually exclusive. Gretchen Mahan tells us more…

At the San Antonio Botanical Gardens, six miniature houses on WaterSavers Lane showcase diverse landscapes and their water saving potential. Sir Oliver Smith, a master gardener, describes the typical landscape, complete with a water thirsty lawn.

This is what most people have. They have the traditional hedges at the door and all that manicuring you have to do every week. So this is probably what we don’t want if you want to save on money and save on grass and save on water.

For comparison, he points out an attractive landscape that replaces turf with groundcover.

People like this look; it’s a little less maintenance. And you’re replacing some of the lawn with Asiatic jasmine, which takes no water.

While the jasmine isn’t native, most of the other plants are. This helps save water because native plants generally require less of it survive.

Everyone thinks native plants are just a sticky agarita and the yuccas and the sotals. But all the other things in this garden are native. Vitex and desert willow and redbud and there are a lot of other things that do very well with almost no water.

And they’re beautiful. Contact your local Extension Service to find out which native plants thrive in your area.

Thanks, Gretchen. That’s our show…Find pictures and more information at passporttotexas.org. For Texas Parks and Wildlife I’m Cecilia Nasti.

Don’t let the fact you’ve never gone fishing—or that your skills are a bit rusty—keep you from casting a line soon.

We do offer classes, but we can’t offer classes to everyone. So, we thought a little video series would help.

Ann Miller coordinates aquatic education for TPW. She said the agency received many inquiries from adults interested in learning to fish for the first time, or who wanted to know how to get their children involved. Miller helped to develop—and hosts—the agency’s new Fishing 101 video series, which demonstrates basic fishing skills.

So, we have really started with the very basic knowledge and skills, just to get people started. Then, of course, we have also included a lot of links to resources, so that people will figure out the next steps to be able to increase their fishing knowledge.

The videos, available on YouTube and the TPW website, are for adults who want to hone their skills.

We do gear this for adults; both to teach them how to go fishing again if they’ve forgotten, or to help them teach their children.

Find links to the videos at passporttotexas.org.

That’s our show…we produce our show with a grant form the Sport Fish and Wildlife Restoration Program…working to increase fishing and boating opportunities in Texas…

Dijar Lutz-Carrillo (DEE-har luhtz—kah-REE-oh) is a geneticist at the A.E. Wood Laboratory in San Marcos.

And we do everything genetics related for Inland Fisheries.

Lutz-Carrillo says geneticists help to answer questions biologists might have about freshwater fish. Some of the questions currently being posed involve DNA “fingerprinting” of largemouth bass.

In terms of the DNA fingerprinting, the questions they’re specifically asking are: is this fish from this reservoir produced in the wild, or produced at the hatchery? And if it’s produced at the hatchery is it with the OWR program—or Operation World Record—and if it’s from that program, who are its parents in that program? So, you’re asking the question who’s your daddy? Yeah, that’s the question (laughs). And your mommy.

Largemouth bass top the list of popular freshwater sport fish…and Parks and Wildlife is attempting to produce world record bass using genetic testing and selective breeding. Loraine Fries (Fr-EYE-Z) is lab manager,

It’s all related to fisheries management and our interest in having the best fishing in the world here in Texas.

We’ll have more on this topic tomorrow.

That’s our show…supported by a grant from the Sport Fish and Wildlife Restoration Program… working to increase fishing, hunting, shooting and boating opportunities in Texas.

Estuaries act as nurseries for juvenile species of saltwater fish. And freshwater inflows keep estuaries in top form.

Freshwater brings sediments which builds nursery areas. Freshwater also brings nutrients which feed the plants and animals that grow and form the basis for the food web in the estuary.

Former TPW Coastal Studies Team Leader, Dave Buzan, says since the 1950’s we’ve restricted water flow to the gulf by building reservoirs and flood control structures.

Historically we have controlled water because we know we need water for people to drink, for industries, and for agriculture.

Human need has effectively changed Texas from a land of rivers and streams into a land of impounded water, meaning less fresh water reaches our estuaries.

In hindsight, we’re able to see that the more of these reservoirs and flood control structures we’ve built have really reduced our ability to get water to the estuary on a consistent basis.

And when fresh water doesn’t flow consistently into estuaries, the health of these ecosystems as well as the health of a significant segment of our economy suffers the consequences.

We’ll look at that tomorrow.

That’s our show … made possible by the Sport Fish and Wildlife Restoration Program…working to increase fishing, hunting, shooting and boating opportunities in Texas.

At first glance, hydrilla—an exotic aquatic plant—seems beneficial to large mouth bass.

The hydrilla acts just as a habitat, refuge, cover for the bass. And so they’ll hide out in that, waiting for a bait to come by.

John Wedig is a supervisor of aquatic sciences at the Lower Colorado River Authority. He says many fishermen use hydrilla to their advantage.
The fishermen realize that [the way bass wait for bait], and now they mimic or imitate that bait with their lure and it improves their chances of catching a bass.

But the fun and games don’t last. Hydrilla is an invasive species, and if it’s not controlled, it can grow into a thick mat that becomes detrimental to fish and frustrating to fishermen.
That’s what we actually experienced on Lake Bastrop years ago, where we had a 900 acre lake with about 600 acres of hydrilla in it. And so there was so much cover, they [the bass] couldn’t get to their food fish. So we actually had what was referred to as “skinny bass.”

Earl Chilton, Parks and Wildlife aquatic habitat enhancement director, says combating hydrilla is an ongoing battle, and total eradication is highly unlikely.

Hydrilla produces tubers. They’re potato like structures that can remain dormant in the sediments for years, sometimes over a decade. So when you think you’ve got it under control, these things are sitting down there waiting to come back.

That’s our show…with research and writing help from Gretchen Mahan. We receive support from the Sport Fish restoration Program…funded by your purchase of fishing equipment and motor boat fuel.
