Become a Frog Listener and Help Save Your State's Frogs

In many parts of the country, frogs and toads have begun their hibernation, and we humans, too, are hibernating for the winter—at least in parts of the northern hemisphere. This is a good time, however, to hone your frog listening skills and to think about volunteering as a frog listener for the North American Amphibian Monitoring Program, (NAAMP) a nationwide program of the U.S. Geological Survey that studies the distribution and relative abundance of amphibians in North America. The data collected from frog listeners across the country is analyzed for patterns of amphibian stability or decline on local, regional, and national levels.

Several states are participating in this study. Georgia’s Department of Natural Resources, for example, has participated in NAAMP, since 2008. In Georgia as elsewhere, frogs serve as indicators of environmental change: the data collected by volunteers helps monitor habitat change or loss of wetlands.

In Georgia, volunteers are asked to drive a predetermined route (or routes), stopping for five minutes to listen for and report frog species and their relative abundance at 10 established wetland stops. They visit these local listening routes three times a year.

Frog listening not only helps frogs, it helps the participants, too. Listening to the frog calls, according to Sarah Barlow, a NAAMP participant, is not only relaxing and enjoyable, it also builds “a greater appreciation of being in the woods.” (Quoted in an online article Frog Listener Volunteers Answer Call To Help Survey Frogs Across Georgia.)

Before becoming a frog listener, you must first take the U.S. Geological Survey quiz and be able to idenfity 65 percent of the frogs in your state. Even if you don’t want to become a frog listener, it’s fun to take the quiz to test your knowledge of the calls of frogs in your state.

So in addition to holiday music, why not plan to listen to some other choruses—frog choruses—in preparation for spring. If you live in Georgia, you don’t have to wait that long. The first listening window next year opens January 15.

Here’s one frog from Georgia with a distinctive call, the Green Frog (Rana clamitans)

Text "FROG" and Help Save a Frog Today

Below is a re-post from the Panama Amphibian Rescue and Conservation project about their newly launched Text-Frog campaign to raise 50 K for their amphibian rescue program. We hope you will consider helping this worthwhile amphibian conservation effort by donating $5 via cell phone. See below for details.

YOU can help frogs!

The price we pay every time we lose a frog species to chytrid is too great to measure. The cost of saving frogs, however, is scant in comparison. But we need your help! That’s why we’ve launched a mobile giving campaign, providing an easy and convenient tool for you to help us battle chytrid and give the frogs a safe haven. Just pull out your cell phone and text “FROG” to 20222 to make a $5 donation to the rescue project.

Every $5 that comes in this way will go toward our new goal of raising the $50,000 it takes to turn a shipping container into a rescue pod. These rescue pods are biosecure “arks” where we can care for frogs that would otherwise be hit hard by the wave of chytrid. Without this ark, we won’t have a safe place to keep the frogs—so help us raise the funds by spreading the word!

So what will your money buy? Check it out:

$5: Three swab sticks used to test frogs for chytrid.
$5: A box of gloves to help ensure the cleanest and safest handling of the frogs.
$5: Pair of Crocs for keepers and visitors to change into to prevent bringing anything harmful into the biosecure rescue pods and areas where the frogs are kept.
$5: Small cricket container—caring for the frogs’ food is an important part of caring for the frogs.
$10: Four gallons of bleach, to keep the floor of the pod and quarantine rooms sterile.
$10: Large cricket container.
$10: Frog quarantine tank.
$15: Tub of yeast to feed fruit flies, which in turn are fed to the frogs.
$20: Calcium powder for frogs to keep them strong and healthy.
$20: Paper towel pack to help clean the tanks.
$30: 100 pounds of tilapia (fish food) to feed the crickets.
$30: Standard frog tank.
$150: Bottle of anti-fungal medication to treat the animals for chytrid.

Watch as our rescue pod fills up with frogs by following the progress of our $50K for Frogs campaign. And make sure to text “FROG” to 20222* to save a frog today! (You can text “FROG” to 20222 up to six times.)

*A one-time donation of $5 will be added to your mobile phone bill or deducted from your prepaid balance. Messaging & Data Rates May Apply. All charges are billed by and payable to your mobile service provider. Service is available on most carriers. Donations are collected for the benefit of the Panama Amphibian Rescue and Conservation Project by the Mobile Giving Foundation and subject to the terms found at www.hmgf.org/t. You can unsubscribe at any time by replying STOP to short code 20222; Reply HELP to 20222 for help. You can also find the privacy policy here.

Fighting to Save Colorado's Boreal Toad

The Colorado Division of Wildlife is struggling to save a local amphibian from extinction—the four-inch boreal toad. Once abundant, it is one of many frog species worldwide threatened with extinction by the chytrid fungus, an infectious disease that is devastating amphibian populations. (See our recent post about some rececent promising chytrid fungus research.)

Boreal toad, Colorado

The federal government has refused to list the boreal toad as an endangered species, claiming it is genetically the same as a toad found throughout the West. Tina Jackson of the Colorado Division of Wildlife and other experts disagree. The toad is, however, a state-listed endangered species in Colorado and New Mexico, and a protected species in Wyoming.

The boreal toads were once common in Colorado’s Southern Rocky mountains. They were found near shallow lakes and beaver ponds at an elevation of 7,000 to 12.000 feet. Thirty years ago, the toads began to disappear. Habitat loss due to logging, grazing, recreation, and water projects contributed to their decline.

But by the late-1990s, the chytrid fungus was identified as the main threat to the toads. Several hundred toads have been raised in captivity and reintroduced to the wild, but so far these efforts have not been successful in producing breeding adults.

At two sites, in Larimer County and in Rocky Mountain National Park, a few introduced toads have survived their first few years. Some of these toads are now 3 and 4 years old, and officials will soon know if they will breed.

The agency has trained volunteers to look for boreal toads while hiking, especially in remote areas where in which toads have not been infected by the chytrid fungus. Toads reintroduced into these chytrid-free areas might have a fighting chance at survival.

Toad Detour

Our last post was about Greek frogs on the move, but close to home, American toads are also on the move and are being helped by an organization called Toad Detour, as reported on Philly.com.

In early March, volunteers with Toad Detour helped adult toads cross a road in Upper Roxborough, Pennsylvania, a suburb of Philadelphia, to get to their breeding ponds. Now the Toad Detour volunteers are helping tiny toadlets make their way back across the road to reach their home in nearby woods. From May 23 to June 30, the Streets Department has provided a permit for the group to detour cars when the toads are crossing.

The toadlets have been traveling by the thousands, especially on damp and rainy nights, and will continue to do so for the next several weeks, according to Lisa Levinson, coordinator of Toad Detour. The toads temporarily halt their migration during dry weather. But nothing else will stop them. A 15-foot rock wall stands in their path, but they hop up and over it.

“One car will kill a thousand of them,” Levinson said. “It’s hard to see them. They look like insects, spiders, or more like flies.”

Volunteers are badly needed to protect the toadlets, set up road barricades, and distribute brochures about the migration, Levinson said. If you live in the Philly area and would like to become a Toad Patroller, visit the Toad Detour website.

Big Chill Helps Mountain Yellow-Legged Frog

One of the most endangered amphibians in North America—the mountain yellow-legged frog—might have some hope this spring due to the collaborative work of researchers at the San Diego Zoo’s Institute for Conservation Research, along with the help of biologists at the U.S. Forest Service, U.S. Geological Survey, and the U.S. Fish and Wildlife Service.

As reported in the Press-Enterprise (Riverside, California), researchers from the San Diego Zoo’s Institute for Conservation Research, which has a captive breeding program for the frogs, discovered that three months hibernation in near-freezing water is what gets these frogs in the mood for love. In the wild, frogs hibernate in icy, high-elevation streams, not in 55-degree aquariums. To mimic these cool temperatures, they were placed in clear plastic shoe boxes called “Valentine’s Day retreats” and stored in the refrigerators.

When they were removed from the refrigerators in April, they displayed breeding behavior within a few days. According to the institute’s Research Coordinator Jeff Lemm, “It has been wildly successful, and as a result, we could reintroduce about 500 eggs into the San Jacinto Mountains.”*

Only 200 individual mountain yellow-legged frogs exist in the wild. Once common in Southern California’s mountain streams, the frog species is almost extinct due to fungal infections, pollution, habitat loss, and predatory trout introduced for fishing. Researchers hope to re-establish wild populations with the captive-bred frogs.

Kudos to students, researchers, and biologists who are helping to save the mountain yellow-legged frog from extinction!

Please see the video below to learn more about efforts to save the mountain yellow-legged frog. This frog species was also featured in the episode Yosemite in the recently rebroadcast PBS documentary The Thin Green Line, about the amphibian decline, which you can watch online.

Vernal Pools: Woodland Nurseries for Frogs and Salamanders

This past weekend, I went hiking with my family in Harriman State Park in New York. We’ve had a very wet spring—well, actually it sometimes seems as if we’ve been living in a rainforest. It’s possible that all this rain will means lots of frogs and toads this summer.

While hiking we found a swamp and listened to a wonderful chorus of spring peepers and (we think) Eastern American toads.

We also saw lots of vernal pools, bodies of water that appear in the spring and last from two to three months before they dry up in the summer. Some types of amphibians, crustaceans, and other wildlife need these pools for breeding, hatching eggs, or as a nursery while they are young. Because they are temporary, vernal pools do not contain fish (which eat tadpoles and larvae).

When you hike by vernal pools, they don’t look like much. In fact, my sneakers got soaked as I tried to jump over one. Yet they are of critical importance to wildlife. I’ve noticed, however, a lot of comments on environmental blogs that read something like this, “Only treehuggers would want to save these mud puddles!” Yet wood frogs, some species of salamander, and fairy shrimp need these “mud puddles” in order to survive. Every year hundreds of acres of wetlands are lost (usually forever) to commercial or residential development. According to the Ohio Vernal Pool Partnership

These usually small, but very dynamic wetlands fill with water, blossom with life and host a cacophony of sounds and a plethora of life forms every spring, only to disappear into the forest floor every autumn…. A vernal pool is a place where a good naturalist can weave many fascinating stories about the amazing life forms, adaptations, and life histories of its inhabitants, and demonstrate it by a single swoop of a dip net! Vernal pool is a miniature, fascinatingly complex and fragile world, with all of its drama played out every year close to our homes, and yet most of us have never witnessed it.
