How do you balance the needs of wildlife and habitat, with wind energy? Find out this month and next on the TPW TV series: Producer Abe Moore.

One of the areas we go is up in the Panhandle, where wind energy is threatening tall grass prairies and the Lesser prairie Chicken, which is there; and it’s got biologists a little concerned.

They don’t do well with change on the landscape. We think that we’re displacing or moving a nesting female away from where she wants to be, and we don’t have much habitat left for her to go to.

We also do a second part on wind energy and we go down to the coast, where wind energy is being developed even faster than in the Panhandle. And, it’s a concern because it’s in the Central Flyway where millions of birds migrate through. So you have all these birds and you’re putting wind turbines in there. So there’s a balance there. We talk with Penescal Wind Farm down there. And they have a radar system set up where they can see the birds coming before they get there.

The radar itself generates a curtailment command, and in less than one minute all the turbines will be turning at less than one RPM. And in within five minutes, all of them are completely stationary.

So, both on the coast, and on the Panhandle, it comes down to habitat issues and trying to site them in the right place.

For more than a decade, researchers at the Heart of the Hills Fisheries Science Center in Kerrville have battled the hybrid progeny of Guadalupe bass—the state fish of Texas—and the introduced Smallmouth bass.

We’re raising thousands of pure Guadalupe bass here at the research station. And every year we stock them back into nature. Basically, what we’re doing is replacing the hybrids that are out there with these pure Guadalupe bass. And we’ll let nature take its course form there.

That’s Gary Garrett, who initiated the Guadalupe bass recovery program. The fish exists only in the Texas Hill Country—in the headwaters of streams that drain the Edward’s Plateau.

Shortly after non-native smallmouth bass were introduced to Texas waters, they bred with native bass, resulting in an explosion of hybrids. But using a technique called “saturation stocking,” Garrett and his crew have made exceptional progress.

So far we’re seeing here in Johnson Creek, where we began eh study, we started where 30 percent of the fish were hybrids. And that wasn’t stable—it was still increasing when we started. It is now down to around three percent. Which is excellent! Top go from thirty to three is great. Now we want to go from three to zero.

And Garrett expects to reach zero in the next four to five years.

Some ideas seem good when you first have them. Then after some time passes—not so much. Take smallmouth bass, for example, and their effect on the Guadalupe bass population.

Small mouth bass, of course, are not native to Texas, but were brought in as an additional sport fish. The problem is they can’t tell each other apart. Even though they look very different, but evidently, they act similar enough behaviorally that they’ll reproduce—and they have hybrids.

That’s Gary Garrett, Director of the Watershed Conservation Program. So, what’s wrong with hybrids, anyway?

Hybrids, by definition, are halfway between the parents. So, they’re not as well adapted for their environment; they may do well in the short run, but in the long haul, they’re really not going to be as good a species.

Besides, they’re the state fish of Texas, occurring only in the Hill Country. And, well, you just don’t mess with Texas.

The other thing we’re now seeing a little bit is that these hybrids are now also crossing with our largemouth bass…which is yet another problem we want to avoid.

And you definitely don’t mess with largemouth bass. But, we’ve started to turn the tide on these hybrids with saturation stocking.

And we’re confident that in the next four or five years we’re going to be able to solve this problem.

To hunt ducks, you need to know where to find them.

People know where ducks typically are—along the coastal zone, maybe in the playa lake region of the Panhandle—but oftentimes they don’t think about these other places.

And those other places might surprise you, says Dave Morrison, waterfowl program leader at Parks and Wildlife.

Had we not been surveying places like the Blackland Prairies and Rolling Plains, people wouldn’t understand that there’s a large number of ducks in Texas on the stock tanks out in the central part of Texas. Sometimes we’ll see upwards of 800-thousand birds there. Those numbers actually, a lot of times, rival the numbers of ducks we count on the coast.

Biologists are presently conducting the annual mid-winter waterfowl survey, where they visually count and ID birds throughout the entire state, in a small plane 150 feet overhead. It helps them understand the birds’ movement, which they discovered is weather dependent.

You get conditions that are dry on the coast, but you get a hurricane that pushes a lot of water up on that brush country, puts a lot of water—guess what—a lot of ducks show up there….that otherwise people wouldn’t know they’re there. They say, well, the ducks aren’t here. Well, yeah they are. They just moved. Habitat conditions forced them into other areas. So, it gives us the ability to better understand where do birds go under different circumstances.

That’s our show…we receive support from the Wildlife restoration program…working to increase shooting and hunting in Texas.

It’s time for the annual mid-winter survey of waterfowl.

Mid-winter surveys are pretty much a snapshot in time that states conduct every year the first week in January.

Dave Morrison is waterfowl program leader at Parks and Wildlife. He says the survey gives biologists an idea of how many of what species are “on the landscape.”

And, what it does for Texas, it gives us a comparison of what Texas has within the Central Flyway. Typically, when we do the mid-winter surveys, compared to the other nine states, seventy percent of the ducks are in Texas during that snapshot in time.

And this is good news for Texas duck hunters, because the survey can tell them where the ducks are.

It provides an opportunity for us, when people start questioning—well, there’s no ducks in Texas—well, we can say ‘no…here’s what it shows.” Because our surveys are designed to be able to detect changes over time. So, if there was a significant decline in numbers of ducks, we’d see it. But, by and large, we’d say, ‘well, they may not be where you’re at, but we know where they’re at. They’re over here.’

See what I mean? What factor moves ducks to unexpected locations? Find out tomorrow.
