Mid-winter Waterfowl Survery, 1

Thursday, January 7th, 2010

This is Passport to 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.

Nature & Child Development, 1

This is passport to Texas

Could spending more time in nature help kids with attention-deficit hyperactive disorder?

The research so far suggests that there’s a relationship between contact with nature or playing in green space and improvements in attentional functioning.

Dr. Andrea Faber Taylor researches child environment and behavior at the University of Illinois. In one study, she had children with ADHD take guided, 20-minute walks in a downtown area, a neighborhood, and a city park, and afterward, tested their ability to concentrate.

What we found was that after the children walked in the park they generally scored higher on the measure of attention. And surprisingly, the neighborhood and the downtown area were not significantly different in scores. That said to us, there’s something about the park that makes it, perhaps, more restorative than the other two settings.

Taylor’s findings match other research as well, which suggest it’s the setting, not just the activity, that’s important.

Based on our work and the work of others, we feel very confident that children benefit from contact with nature or even just what we call green space, a small pocket of trees and grass. Certainly, we’re not suggesting that it’s going to cure a child from ADHD, but it appears to, at least, temporarily reduce their symptoms.

Catfish: A Fish for Texas’ Future

Tuesday, November 24th, 2009

This is Passport to Texas

Texas is known for its bass angling, but chief of inland fisheries management and research, Dave Terre, says catfish angling is gaining popularity.

Today in Texas, about 50 percent of our anglers say they prefer largemouth bass. But, about 20 percent of anglers prefer fishing catfish in Texas.

Parks and Wildlife is meeting the challenge.

We’re trying to launch an initiative that will help us understand what our anglers needs and desires are for catfish angling in the state. And then study catfish more intensively to determine how we can make fishing for catfish even better.

September first, new regulations governing the harvest of blue catfish went into effect at Richland Chambers Reservoir, Lake Waco and Lake Lewisville—water bodies offering trophy potential for catfish. Find the regulations on the Parks and Wildlife website.

Meanwhile, Terre says as our climate changes, and extended droughts continue to plague our state, catfish will have an important role to play.

Catfish are able to deal with fluctuating water levels better than largemouth bass which have been, and will continue to be, a popular sport fish in Texas. So, managing catfish more intensively will mean that we may be able to provide more fishing opportunities for Texans in the future years.

Recruiting a Few Good Prairie Chickens

Tuesday, November 17th, 2009

This is Passport to Texas

The military…corporate America…and sports teams all depend on good recruiting—something they have in common with the endangered Attwater’s Prairie Chicken.

Historically, this bird went through periods of time when a population would be devastated, and then it would recruit from neighboring populations.

But they’ve had to change their recruiting tactics, says Mark Klym, Adopt-a-Prairie Chicken Program coordinator.

Today those recruits have to come from the zoos.

Development destroyed the prairie chicken’s coastal habitat, reducing its population from a million birds at the turn of the 20th century to just 90 animals today—and that’s up from an all time low of 40 in 2005. Currently Three small populations are being maintained in the wild.

The bird is being reproduced for release. We are confident that we have enough birds that we can maintain these three populations now that we have in the wild. But there are biologists out there working with landowners every day trying to get land back in condition. And we have a number of landowners just waiting and asking for release of the birds on their land.

Klym maintains the Attwater’s Prairie Chicken will continue to rebound, and not go quietly into that good night.

We frequently get emails and calls asking when we expect this birds to go extinct. We don’t expect it to go extinct. This is going to be another good news story.

Attwater’s Prairie Chicken Revival

Monday, November 16th, 2009

This is Passport to Texas

Up to a million Attwater’s Prairie Chickens once occupied more than six million acres of coastal prairie in Texas. By 2005, only 40 birds were estimated in the wild.

That happened primarily because of a loss of habitat. You’ve got places like Houston, Corpus Christi, and as these cities developed, they took a lot of the coastal prairie away. And we also have the problem of Chinese tallow escaping and changing the coastal prairie into a tallow forest.

Mark Klym coordinates the Adopt-a-Prairie Chicken Program.

The Adopt-a-Prairie Chicken program is a fundraising program; seven zoos around the state put a lot of energy into raising birds that are going to be released on the prairie. And this is one way that the people of Texas can get involved and help us to support these zoos.

Thanks in part to this program, recovery efforts for the Attwater’s Prairie Chicken reached a new milestone this year when 6 hens raised 21 chicks to 6-weeks of age in the wild.

And this hasn’t happened before. One hen did do it a couple years ago, but she had a lot of help from the staff at the Attwater’s Prairie Chicken Preserve. This year, some of these hens did it with no assistance at all. And it happened not only at Attwater’s Prairie Chicken Preserve, but also on private land in Goliad county.

Today, there are an estimated 90 Attwater’s Prairie Chickens in the wild at three locations. We’ll tell you more about this bird tomorrow.
