Endangered Species: Houston Toad

Passport to Texas from Texas Parks and Wildlife

[Call of the Houston toad]

That sound is the Houston toad. And it’s become a very rare sound over the past two decades. Years of drought and habitat destruction have diminished the Houston toad population to only a few hundred.

Michael Forstner is a professor at Texas State University. And through the Texas Parks and Wildlife Landowner Incentive Program (L.I.P.), he’s working with private landowners in Bastrop County to restore habitat for the Houston toad.

Most of the people in Bastrop want to live in Bastrop County because it looks a certain way. And if it keeps looking like the lost pines, we keep the toad.

So what do these “lost pines” look like?

Imagine a cathedral forest. Most of the habitat that we find Houston toads doing the best in, whatever that means for its current levels, are gallery forests. Those are the forests that you see in the images for computer desktop wallpapers. Those are large-trunked trees with open space beneath them.

By planting the fast-growing loblolly pine trees, a habitat can be restored in about twenty years.

So if current efforts are successful, Forstner says the Houston toad population could make a comeback.

The best thing about the Houston toad is they make 6,000 eggs at a time. Those babies just need a place to grow up.

Kerr Wildlife Management Area

Passport to Texas from Texas Parks and Wildlife and the Sport Fish and Wildlife Restoration Program

The Hill Country is the crown jewel of Texas. And the Kerr Wildlife Management Area teaches landowners how to keep it polished.

We’re a 65-hundred acre wildlife research and demonstration area for the Edward’s plateau ecological area. And it serves as our experiment station for private landowners to come out and find out more about the basic tools of wildlife management.

Donnie Frels is the area manager. While wildlife species at the Kerr WMA are typical for the region, plant diversity is unique by Hill Country standards.

We keep animal numbers in check, and we make sure that we maintain our grazing animals within the carrying capacity of the range, and our plant species and diversity reflect that now.

Research on the site also protects three endangered species: the golden-cheeked warbler, black-capped vireos and the tobusch fishhook cactus.

And we do surveys for all three of these species; and our management program benefits not only white-tailed deer but those endangered species as well.

The site is open to the public for wildlife viewing during daylight hours when public hunting is not underway, and offers a driving tour brochure for those visiting the site. Learn more at passporttotexas.org.

Endangered Ocelots, 2

Friday, June 12th, 2009

Passport to Texas from Texas Parks and Wildlife and the Wildlife Restoration Program

Texas is the only US state with suitable Ocelot habitat.

The habitat that ocelots use is extremely dense brush. The type of brush that not only can you not see through it, you can’t walk through it.

Dr. Michael Tewes (two-ES) researches wild cats with the Caesar Kleberg Wildlife Research Institute.

The main problem for ocelots now is, like many other endangered species, the lack of suitable habitat. There are less than 100 of them remaining in Texas and less than 1% of Texas has that very special habitat or cover type that they use. And since most of Texas is owned and managed by private landowners and ranchers, it is in their ability to protect the habitat that is vital to the recovery of ocelots.

Fewer ocelots mean less genetic diversity.

When the populations are as small as they are in Southern Texas, almost any kind of a wildlife population will start to decrease genetic diversity and tend to go towards extinction. We have been working on revising the recovery plan and, although it’s not finalized, translocation is suggested as a tool. The genetic diversity is much greater in Mexico than it is in Texas. And by bringing them into Texas it would help alleviate some of the problems that come with genetic erosion.

That’s our show… with research and writing help from Sarah Loden… and sponsored by the Wildlife Restoration program…working to restore critical habitat for endangered species like the ocelot.

Endangered Ocelots, 1

Ocelots are small wildcats that are spotted like jaguars and leopards; some of these animals live in South Texas.

We only know of two breeding populations in Texas. They occur primarily in Southern Texas now. Historically, ocelots occurred throughout much of Central and East Texas.

And they lived along the river banks. Dr. Michael Tewes (two-ES) has researched wild cats with the Caesar Kleberg Wildlife Research Institute for 25 years. He says these beautiful animals are being driven to extinction by development, inbreeding, and habitat loss.

The population here in South Texas represents the United States population and there are less than 100 of them remaining. Therefore, they’re an endangered species. When the populations are as small as they are, almost any kind of a wildlife population will start to decrease genetic diversity and tend to go towards extinction.

Hear about the proposed recovery plan to restore the Texas Ocelot population tomorrow.

By increasing the genetic diversity of such a small population you can help reduce the amount of mortality that is increased with low genetic diversity, and increase survival and increase reproduction. There’s a stronger, vigorous population in Mexico that can be used to help augment the two populations that we have here in Texas.

That’s our show… with research and writing help from Sarah Loden… and sponsored by the Wildlife Restoration program…working to restore critical habitat for endangered species.

TPW Magazine January Preview

Passport to Texas from Texas Parks and Wildlife and the Wildlife Restoration Program

The January 2009 issue of Texas Parks and Wildlife magazine focuses on the multi-faceted issue of endangered species. Managing editor, Louie Bond.

And so, we’re taking it, kind of, almost as a theme through the magazine. Starting out with our “At Issue” by our Executive Director, Carter Smith, who quotes the famous American Conservationist, Aldo Leopold, who says: There are some who can live without wild things, and some who cannot. And, of course, here at Texas Parks and Wildlife, we fall into the latter category. We cannot live without any of these wild things. The main reason for a lot of the problems that these species are having is habitat loss. But there’s also some subtle things that go on, for example, wild fire control. I know that you and I grew up with Smokey the Bear—and tried to stamp out forest fires—which is a great cause. But, forest fires are a fact of life, and they’re Mother Nature’s way of getting rid of some undergrowth. And that does affect some of these species. And, I think that Carter Smith wraps it best. He says at the end of his at issue column this month, “I have no doubt that if we can collectively succeed in this worthwhile endeavor, our children, and their children, and their children after that, will be forever grateful. And if we don’t—they may never forgive us.”

The January issue of Texas Parks and Wildlife magazine is on newsstands now.
