Conservation: Dogs Sniff Out Invasive Weeds

Using their keen sense of smell (often to locate scat), trained conservation detection dogs assist with monitoring endangered wildlife, defining wildlife corridors and helping to eradicate invasive species.

06—Almost all of our work is in partnerships with non-profits, or agencies or sometimes universities.

Pete Coppolillo is Executive Director of Working Dogs for Conservation in Montana.

13—It’s really cost effective because you can find information about a lot of animals without having to fly a helicopter around and dart them and capture them and do things like that.

Lab analysis costs are decreasing, too, making it easier to obtain more information from scats. Yet, some successes have nothing to do with wildlife.

29—I’ll give you one example: there’s a weed here in Montana called dyers woad that has infested large parts of Utah, and then it appeared here. For a long time, the expectation was we’ll never get rid of it [because one plant can set 10,000 seeds]. Because dogs are so good at finding it, and because they can find it before it flowers or sets seed, we are close to eradicating that plant in a place called Mount Sentinel. You know, it’s a really powerful, scientifically rigorous tool, and it opens the door to doing things we hadn’t dreamed of.

You can learn more about conservation detection dogs, and see pictures of the dogs, Working Dogs for Conservation.

Working Dogs for Conservation in Bozeman, Montana trains dogs to help researchers in the field.

05—One in fifteen hundred dogs that we screen has what it takes to be a conservation detection dog.

Some of the program animals are rescues. Pete Coppolillo, Executive Director, says they train the dogs to detect everything from scat, to live animals, to invertebrates, and even invasive weeds.

12—We select for high drive so that they’ll want to do it and work really hard at it. And we also select for dogs that are toy obsessed – that are really excited about a specific toy. And that’s their reward, and that’s also how we train them.

At the time we spoke, Working Dogs for Conservation had just deployed animals to Africa to help fight the illegal ivory trade. Pete told me how they used toys to train the dogs for that assignment.

22—The ivory dogs were trained by hiding ivory with their toy. So, they’ll come in and they’ll sniff around and they’ll begin to associate the scent of ivory with their toy. And as soon as they discover the toy is sitting right behind the ivory, and they get a big whiff of ivory and then they get their toy – and so they get their reward. And then, gradually we separate the toy from the ivory; they learn as soon as they find it they get their toy and their reward.

Tomorrow: some positive results of working the dogs. Learn more about these dogs at Working Dogs for Conservation.

Most dogs like to work. And Pete Coppolillo is hiring. He is Executive Director of Working Dogs for Conservation in Bozeman, Montana. Since the mid-1990s, his organization’s trained dogs as a non-invasive alternative method for collecting data on hard to find wildlife.

05—By non-invasive, I mean we don’t have to capture them, we don’t have to handle them, we don’t even have to see them.

Then, just how are researchers using dogs?

06—So, the idea is we train a dog to find their scat, usually, which to non-biologists is a polite word for poop.

By detecting scat, the dogs help researchers determine the range, sex, and diet (among other things) of certain wildlife species. Pete said they first trained dogs to sniff out grizzly bear and wolf scat, but didn’t stop there.

28—Dogs can do everything from scat to live animal work to invasive weeds. Even invertebrates, like Emerald Ash Borer; they can find their larvae or their eggs. And, [we] even [use the dogs to detect] aquatic invasives like zebra and quagga mussels – to inspect boats. Because, the mussels can be in cracks, or inside, where a visual inspection can’t see them. Or the dogs can even detect the veligers, which are microscopic larvae that we can’t see.

Not all dogs are suited to this work. Learn more about these dogs at Working Dogs for Conservation.

More on that tomorrow. The Wildlife and Sport Fish Restoration program supports our series and funds diverse conservation projects in Texas.

Fishing: Big Fish with Big Fight — Alligator Gar

Friday, November 7th, 2014

Alligator Gar in the Trinity River

Alligator Gar in the Trinity River



This is Passport to Texas

Alligator gar, virtually unchanged from prehistoric times, is attracting an enthusiastic 21st Century following.

04—The species in recent years has become very popular amongst anglers and bow fishers.

David Buckmeier is a fisheries scientist for parks and wildlife. To fish for gar, you have to know where to find them.

21—Most alligator gar are found in coastal rivers along the eastern part of the state; rivers like the Trinity are very, very well-known for their alligator gar populations. They’re also found in our coastal bays. They’re an interesting species in that they can go back and forth—maybe not into full salt water like in the gulf—but definitely in the bay systems. And they can go back and forth into the river and into those upper parts of those bays.

The alligator gar is the largest freshwater fish in Texas and gives anglers a good fight.

16—Yes, they actually fight quite well. As you can imagine, any fish that weighs 150 or 200 pounds has a lot of power. So, they do fight; they actually jump quite a bit. They’ll completely clear the water. There’s some variations; some of them are more sluggish than others. But, they’re very entertaining and that’s the reason, I guess, for the popularity.

Anglers may keep one of these big fish per day. Learn more about freshwater fishing at the Texas parks and Wildlife website.

Conservation: Money for Quail

Bobwhite quail in Texas

Bobwhite quail in Texas



This is Passport to Texas

There’s new hope for bobwhite quail.

13—Four million dollars of the upland game bird stamp fund was authorized by the legislature this past session to specifically go towards further developing this concept of focus areas for bobwhite quail and grassland birds.

The “focus area” concept is one TPW upland game bird program leader, Robert Perez, has worked on for years.

08—Well, a focus area is an intensive effort within a small area to demonstrate that quail restoration can be successful.

Most focus areas are east of the I-35: places where quail are gone, said Perez, but they haven’t been gone long.

23— One of our focus areas in the Columbus-Seely area, southeast Texas. Another is the Navarro-Ellis area, along the I-35 corridor where Waxahachie is. Another is West of Dallas a good ways over towards Wichita Falls, around Clay County and south. So these are the front lines of bobwhite decline; birds are still around, but they’re noticeably rarer.

The agency awarded 15 grants, with two more in process, to nonprofits, universities and others for grassland restoration. Grantees will use the $4 million dollars over a two year grant period.

19—But that doesn’t mean that the project is over at the end of two years. Because the impacts – when you start to turn the dirt or manipulate habitat – those effects go on for years. And so what’s most important is to continue to monitor – think of the future beyond those two years – to really understand and paint a good picture of what the impacts are of these types of manipulations.
