The Matador Wildlife Management Area offers vistas of colorful rolling plains and canyons. Texas Parks and Wildlife maintains the beauty and balance of this 28-thousand acre natural landscape with the regular use of an ancient tool.

Right now they are preparing to light a test fire. It gives us a pretty good indication of what the fire behavior is going to be like. And since it’s a test, if it doesn’t work out, we can put the fire out and go for it another day.

Chris Schenck is part of Texas Parks and Wildlife’s prescribed fire crew. A segment about prescribed fire airs next week on the Texas Parks and Wildlife TV series on PBS. Team member, Derreck Holdsctock, says fire is an important, natural process.

Whenever you don’t have fire brush encroaches. The more brush there is, the higher the fire danger is going to be during a dry year. So the more fire you put on the ground the less the effects of a wildfire will be and the more controllable it will be.

Prescribed fire has many jobs. It knocks back invasive plants, returns nutrients to the soil, and promotes native species, creating a balance of cover and forage for wildlife.

Every time we do a fire I feel like we’re taking a big chunk out of our management of that area. And then when you come back three months later and you have all this tall grass and you have all the wildflowers out there, it just kind of brings it all together and you realize what you’ve accomplished.

Catch the segment on Prescribed Fires this week on the Texas Parks and Wildlife TV series on PBS. Check your local listings.

Wildflowers for Truth and Beauty

Texas roadsides will soon  be awash in colorful wildflowers. Dr. Damon Waitt, director of the North Carolina Botanical Garden, formerly of the Ladybird Johnson Wildflower Center, says these and other native plants have a place in the natural and built landscapes.

Natives provide really important ecosystem services for local wildlife, pollinators.

They filter storm water and rainwater, so they provide all these services to the ecosystem, and they can provide similar services in the built landscape, and reduce things like water use, pesticide use and fertilizer use.

In addition, they have the aesthetic qualities that we want people to learn to appreciate, so they’re not looking for that next exotic ornamental—that they ‘re more interested in finding that next native plant that looks great and functions perfectly in their environment.

There are a lot of people who might look at wildflowers and native plants and say, gosh, how do those fit into my idea of a formal landscape.

That’s something we’re really trying to fight—that concept that if you’re a native plant enthusiast, then your yard must look wild and unkempt. At the wildflower center, we model different design styles using native plants, and you can use native plants in very high designs and very formal designs if that’s the look you’re going for.

Find plants that are right for you at wildflower.org.

NOTE: Due to the rain and warm weather, spring wildflowers started popping out about a month earlier than usual. So get out there soon to enjoy them before they’re gone.

Plight of the Bumblebee

Texas has nine native bumblebee species. Loss of habitat to agriculture, use of pesticides, as well as European honeybees competing for food, threatens these important pollinators.

And so if we have a reduction in bumblebees, that spells trouble for our ecosystems.

Michael Warriner, an invertebrate biologist, says because Texas bumblebees have evolved with native flora as pollinators, fewer native bees would eventually translate to fewer native plants, which would impact other living things…

The birds and the mammals and other insects that depend on plants for fruit, or seeds, or just the functioning ecosystem.

While we give non-native European honeybees credit for pollinating our food crops, in some instances, bumblebees outperform them.

14—Bumblebees, although they aren’t talked about a lot as important pollinators, they’re much better and more efficient than honeybees. They’re the best pollinators for things like tomatoes, blueberries, cranberries, melons, and those sorts of crops.

You can find more bumblebee on the Texas Parks and Wildlife website.

11—And if you’re interested in being a bumblebee watcher, check out the website, and if you see any bumblebees in your garden, just send in photos. We’re really trying to learn how bumblebees are doing.

Threats to Texas Bumblebees

We all know about colony collapse disorder whereby colonies of European honeybees seem to vanish.

Less well known are the threats facing a lot of our native bumblebees.

Michael Warriner is an invertebrate biologist with a soft spot for native bumblebees. Like other native wildlife species in Texas, habitat loss is taking its toll on native bumblebees.

Bumblebees need open, flower-rich habitat—like grasslands. And, a lot of that habitat’s been converted to agriculture.

Warriner says pesticide use is another concern, but the threats to these big black and yellow insects doesn’t stop there.

And also, there’s been the importation of bumblebees from Europe into this country which has brought in parasites and diseases that may be impacting them. So, there’s a lot of concern how they’re faring in North America.

One of the threats to Texas bumblebees might actually be honeybees, which have colonies in the tens of thousands compared to the hundreds of insects in a bumblebee colony.

Honeybees have these tens of thousands of workers, and so they can go out and monopolize a flower resource—like nectar or pollen—and that reduces what’s available for our native bees. And there’s some research that suggests that the presence of honeybees in natural sites can reduce native bees.

We’ll have the potential impact from bumblebee decline tomorrow.

TPW TV – Guzzlers for Wildlife

Guzzler on the Black Gasp Wildlife Management Area

Guzzler on the Black Gasp Wildlife Management Area

This is Passport to Texas

A guzzler is a rain catchment device. Collected rainwater gets funneled into a tank that feeds a water trough for wildlife.

As we all know, animals need water. Our annual rainfall is only around 11 inches a year. So we’re trying to supplement that water during dry periods.

Travis Smith is a biologist at the Black Gap Wildlife management area in Brewster County. So is Will Rhodes.

We’re in southern Brewster County which is in the Trans-Pecos region of Texas.

They build and maintain guzzlers on the Gap—45 so far—and see to the needs of wildlife on the management area.

We’re in the Chihuahuan Desert Ecosystem. The area is 103,000 acres or a little over. Black Gap is kind of in the middle of nowhere.

Next week the men explain and demonstrate guzzlers on a segment of the Texas Parks and Wildlife TV series on PBS.

So this catchment consist of R-Panel in 12 foot lengths, which is connected to these 6 inch C-Purlins by…

Let’s stop there. Will’s going to tell us about purlins and pitch threads and storage tanks; it’s not sexy stuff. But it’s necessary when building guzzlers at Black Gap. And, so are wildlife cameras.

On these game cameras it’s triggered by motion. Usually that’s going to be wildlife coming in to get water from the guzzlers here.

Which means their efforts are successful. See the segment on Guzzlers next week on the Texas Parks and Wildlife TV Series on PBS. The Wildlife Restoration Program supports our series.
