Invasives: Zebra Mussels Play Now | Play in Popup | Download

There are two types of aquatic mussels in Texas: those that belong here, and those that don’t.

Texas Parks and Wildlife aquatic habitat enhancement director Earl Chilton says native mussels indicate when rivers and lakes are healthy.

10—Native mussels often have pretty strict environmental requirements, and you can tell whether a system is healthy or not by the kind of native mussel population it has.

Invasive species like zebra mussels aren’t native to Texas. Because they have no natural competitors here, they reproduce quickly. And large numbers of zebra mussels can clog pipes and even kill native mussels.

14—Unlike native mussels, zebra mussels have byssal threads they use to attach to various objects. They also can attach to native mussels and when enough of them attach to a native mussel they can actually suffocate that mussel.

So how can you tell the difference between these good and bad mussels?

07—Zebra mussels are small and they’re going to attach to things. If you see a mussel attached to something it is a non-native mussel.

But native freshwater mussels don’t attach to anything. Now that you know the difference, you can find out how you can help stop the spread of zebra mussels and protect the native species www.texasinvasives.org.

State Parks: Campfires Allowed Play Now | Play in Popup | Download

Starting a campfire in a state park this past summer wasn’t just a bad idea, it was terribly dangerous given the drought, and so it was banned. But now that winter’s here and we’ve had some rain, we can start to cozy up to campfires again. Our State Park Guide Bryan Frazier has details.

48— With the drought that we had in Texas, most people are understanding that that affects everything we do. And at the end of the summer—at the apex of that drought—we had burn bans in more than 200 counties here in Texas.

And so it’s a nice natural place to gather. So having those burn bans lifted in most of our counties is really good news for a lot of people who want to get out and enjoy an old fashioned campfire for their camping experience.

Thanks Bryan.

Wildlife: Year of the Lizard Play Now | Play in Popup | Download

The non-profit Partners in Amphibian and Reptile Conservation, or PARC, designated 2012 as the Year of the Lizard.

06—Lizards are a group of organisms that scientists have said: you know, we really haven’t paid much attention to what’s going on with them.

Biologist, Leeann Linam, oversees the Texas Nature Tracker program for Parks and Wildlife. When lizard populations are thriving—or not—chances are they are mirroring the environmental conditions in which they live. Because of this, they deserve our attention.

Leeann says putting the spotlight on these cold-blooded creatures may help us warm to them.

14—if you stop and watch a lizard, they’re really an interesting creature. And I think that’s what the challenge is for us—to spend enough time outside to really observe them. If you zoom in on them, and take a closer look, they’re just really fascinating—like mini dinosaurs.

So how does one best observe the year of the lizard?

14—At Parks and Wildlife we we’ve got some ways for people to participate. For example, our Texas Horned Lizard Watch asks people to become partners with us in monitoring what’s going on with our state reptile—the Texas Horned Lizard—and the other two horned lizard species that are found in the state.

Wildlife: Herpetology Play Now | Play in Popup | Download

Herpetology is a branch of zoology concerned with amphibians and reptiles. Although scientists classify both as herps, Leeann Linam says differences exist.

16—Amphibians are the species that are associated with water in their life-cycle. [They’re] smooth skinned, and usually lay their eggs in water and often have a larval stage such as a tadpole for a frog. So frogs, salamanders, and an interesting creature called the caecilian are amphibians.

Leeann is a biologist with Parks and Wildlife. Reptiles are those species that have scales and tend to lay their eggs on land in dry nests, and have hard-shelled eggs.

13—And so we have several divisions of reptiles as well. We have the turtles, we have the lizards, and we have the snakes… And then there are a few other groups. The crocodilians and some others that are kind of unique.

Of the reptiles, says Leeann, scientists agree they need to give them more consideration.

14—Lizards are a group of organisms that scientists have said: you know, we really haven’t paid much attention to what’s going on with them. They are mostly eating insects in the environment, and so one can perhaps think of them as being sensitive to things like pesticides and habitat loss, as well as direct persecution, or killing, as areas are changed in terms of their use.
