TPW TV: Endangered Prairie Chickens

Friday, February 3rd, 2012


This is Passport to Texas

One of the most endangered birds in North America is the Attwater’s Prairie Chicken. Learn about efforts to help protect this species this month on the Texas parks and Wildlife TV series. Producer, Abe Moore.

57—There used to be close to a million of them in Texas and Louisiana; now they’re teetering around a hundred or so. I went down to the Attwater Prairie Chicken National Wildlife Refuge by Eagle Lake. It’s kind of their last stronghold right now.

Over the last 15, 20 years, there have been fewer than a hundred individuals in wild populations. And for a species that only lives on average two years, that’s a very bad place to be.

So I followed the biologist there for a breeding season, to see what it takes to keep the birds from going extinct. And they’re doing some hands on work building fences actually around the nest sites to protect the female.

The idea of this predator deterrent fence is to deflect predators away from the nest area so that hopefully they won’t find the nest and destroy it.

So, the team goes through some serious struggles this breeding season, and one of the things that happens is they have an ace up their sleeve to kind of help the Attwater Prairie Chicken from going extinct.

Abe says he won’t provide any clues to that ace. We’ll just have to tune in to find out. Check your local listings.

TPW TV: Big Horn Sheep Restoration

Monday, January 23rd, 2012


This is Passport to Texas

By the early 1960s native Texas bighorn sheep, which once populated 16 mountain ranges in the Trans Pecos, were gone. Unregulated hunting and disease from domestic sheep brought in by landowners did them in. But Texas Parks and Wildlife TV producer Bruce Biermann says a segment [on the TV show this month] spotlights a successful restoration project.

64—This story is called Home Again, because the bighorn sheep are finally being brought home again. For the very first time they are being released on a state park.

We show the population here it lives at Elephant Mountain. The capturing process is really interesting, with the use of helicopters.

Once they come upon a herd, they try and capture what they call family units. That’s another measure taken to increase survivability.

They use a net gun and shoot a net over the sheep, and then a guy goes down and handles the sheep and gets is shackled, blindfolded and into a bag that they then sling underneath the helicopter and bring back to processing. And then they release them out at Big Bend Ranch State Park.

Forty six sheep were captured at Elephant Mountain and released. And, of those forty-six that I know of, they’ve had three die to mountain lions. But, that’s part of the normal cycle. They’ve had many babies already born. So, the birth rate is far outgrowing the death rate. And the population is surviving and thriving.

Thanks Bruce.

Whoopers Could Break Record

Friday, December 16th, 2011


This is Passport to Texas

The last naturally breeding wild flock of endangered whooping cranes winters along the Texas Coast at the Aransas National Wildlife Refuge, near Rockport.

04—they spend from about mid-November to about mid-April here in Texas.

Lee Ann Linam is a biologist with the Wildlife Diversity Program at Parks and Wildlife. We spoke in mid November when the birds were just beginning to show up along the coast following their long migration from their breeding grounds in Canada.

10—We have about 25 or 26 whoopers that have been sighted on the Texas coast. We normally, though, don’t get our final count until late December or perhaps early January.

The flock was nearly extinct in the late 1930s 1940s with fewer than 20 members, but its population has grown slowly thanks to well-coordinated efforts to protect habitat and the birds.

20—We had a peak of 283 in Texas last winter, which was a new record. We had approximately37 to 40 chicks that were fledged and were ready to fly I n late august in Canada, according to aerial surveys. So, if we get good enough survival, then we might hit that magic 300 mark.

The Aransas National Wildlife Refuge has a website that updates whooper arrivals, but…

04—The very best experience is to go down and see whooping cranes for yourself.

That’s our show for today. The sport fish and Wildlife restoration program supports our series and fund conservation programs in Texas. For Texas Parks and Wildlife…I’m Cecilia Nasti.

Whoopers Continue to Rebound

Thursday, December 15th, 2011


This is Passport to Texas

As many as 1,400 whooping cranes migrated across North America to the Texas coast in the mid-1800s. By the mid 1940s, the population that wintered here was down to just 18 birds.

08—In the early days, it was primarily unregulated shooting that was causing loss of whooping cranes. And that was something that was fairly easy to control.

Lee Ann Linam is a biologist with the Wildlife Diversity Program at Parks and Wildlife. Because of well-coordinated efforts to protect habitat on the part of both agencies and private landowners, the birds have rebounded, but challenges remain.

11—But now the issues are pretty complex. Things like drought and climate change contributing to things like reduced freshwater inflows. Even the red tide occurrences are threatening the coast this year.

Healthy estuaries are critical to the survival of this magnificent species.

17—In the long-term, we as Texans have the challenge of figuring out how to keep those entire ecosystems healthy with sufficient freshwater inflows; balancing water needs and water uses, because everyone really is affected. So things like water use planning that are going on too, is an important part of the picture.

How many whooping cranes might we see in Texas this winter? Find out on tomorrow’s show.

Prairie Dog Monitoring

Friday, November 18th, 2011


This is Passport to Texas

08—(AMB: prairie dogs calling”)

The black-tailed prairie dog population has declined dramatically throughout its range in Texas.

09—They originally covered a large portion of the state. And we currently have somewhere around one percent of the population that was originally here in the state.

Marsha may coordinates Texas Nature Tracker programs for Texas Parks and Wildlife. You can help wildlife biologists understand this population decline by participating in the Texas black-tailed prairie dog watch. There are three ways to get involved.

19—Volunteers can get involved just monitoring a population of prairie dogs on public property. Then we have adopt-a-prairie dog colony, where folks can go out and monitor a colony wherever they find a permanent colony they’d like to research. And then the third was is the most intense, and that’s a density study.

You’ll need a monitoring packet, and can get yours online from the TPW web site, or have one mailed to you. It’s important to preserve all native species, even this chubby ground-dwelling rodent; because if prairie dogs were gone…

09—We would lose habitat for burrowing owls and food for many hawks. We would lose, also, the prairie habitat that they maintain.
