SAVE THE FROGS! builds low-cost, long-lasting, aesthetically-pleasing wetlands that attract and support wildlife.

Amphibian populations have been rapidly disappearing worldwide and nearly one-third of the world's amphibian species are on the verge of extinction. Habitat destruction is the number one cause of amphibian population declines worldwide and the majority of America's wetlands have been destroyed or modified. To remedy this problem, SAVE THE FROGS! is Re-Frogging America by constructing actual wetlands for frogs and other wildlife. Constructing wetlands is a fantastic method of educating students, teachers and community members about amphibians and ensuring that amphibians have a home in which to live and breed. Wetlands cost money to build, so please donate to SAVE THE FROGS! and help us Re-Frog America! We also invite you to attend our Wetlands Construction Workshops so we can teach you how to build wetlands!

SAVE THE FROGS! and UCLA build wetlands for California Tiger Salamanders

Earlier this year, UCLA researchers asked SAVE THE FROGS! to help them build 18 research wetlands in Monterey, CA. The aim of the project is to assist the endangered California Tiger Salamander (Ambystoma californiense; hereafter CTS). The CTS is an endemic species only found in California, making it an important amphibian to protect. On June 30th and July 1, 2017, SAVE THE FROGS! Wetland Coordinator Kathlyn Osagie designed the wetlands, and on September 26th and 27th she returned to Monterey, CA and led the construction of the wetlands.

The non-native Barred Tiger Salamander (Ambystoma mavortium) has been interbreeding with CTS, creating hybrid offspring that are genetically and physically different than both parent species. These hybrids are not pure CTS and thus negatively impact the CTS populations.

UCLA researchers are studying the hydro-period preferences of the native CTS and the hybrids. The CTS and hybrids have different rates of development in vernal pools, and because the pools dry up each year, the animals that do not metamorphose quickly enough often dry up and die. Thus there is a strong selection towards salamanders that metamorphose quickly. A previous study that used cattle tanks suggests that CTS prefer ponds with shorter hydro-periods, while hybrids prefer longer hydro-periods. This study hopes to uncover if the same results are found in wetlands versus cattle tanks and what the preferred hydro-period for CTS versus CTS hybrids. This information can assist land managers in designing wetlands that benefit the native CTS, while excluding or limiting the unwanted hybrids.

Building Wetlands For California Red-Legged Frogs In Eldorado National Forest

California Red-Legged Frogs (Rana draytonii) were once abundant in California, but their numbers declined drastically in the mid-1800’s when gold miners began eating them in large quantities and their mining activities eroded hillsides and polluted the water bodies the frogs rely on. Modern day Californians negatively impact California Red-Legged Frogs by destroying the frogs’ habitats for homes, roads, timber, golf courses and shopping centers. To make matters worse, over two million live non-native American Bullfrogs (Rana catesbeiana) are imported into the state each year for use as food, and the bullfrogs are voracious predators of California Red-Legged Frogs.

There is hope for the red-legged frogs however: in 2014, SAVE THE FROGS! led a successful campaign to make the California Red-Legged Frog the state’s official amphibian, and we initiated our efforts to Re-Frog America by constructing wetlands for these and other threatened amphibians.

California Red-Legged Frogs had not been known to breed in the Eldorado National Forest for many years, but one lake that borders the forest (Lake Of The Cross) was being used successfully by the frogs for breeding. As such, the Eldorado Forest Service contacted Tom Biebighauser of the Center for Wetland and Stream Restoration for his assistance in creating wetlands on the Forest Service property.

In October 2014, SAVE THE FROGS! biologists Dr. Kerry Kriger, Kathlyn Franco and Emily Moskal joined Tom, the U.S. Forest Service and the American River Conservancy as well as biologists from several other state and federal agencies, and together we created nine wetlands for California Red-Legged Frogs over the course of a week. Prior to construction, various people had stated that these wetlands would not function; however, despite a severe drought, seven of the wetlands naturally filled with water, and followup surveys found California Red-Legged Frogs using the new habitats! Our wetlands are assisting an iconic and federally-listed amphibian - this is a huge success!

In October 2016, SAVE THE FROGS!, the U.S. Forest Service, the American River Conservancy and Tom Biebighauser returned to Eldorado National Forest to conduct more surveys and to build more wetlands. SAVE THE FROGS! invited volunteers, as one of our prime objectives is to train biologists and landowners how to build wetlands.

On October 3rd and 4th, 2016, SAVE THE FROGS! and our partners created two new wetlands for the California Red-Legged Frogs - and they have been successful. Maura Santora (US Forest Service Aquatic Biologist) informed us that one month after the construction, red-legged frogs were found using both of the ponds!

Here's what SAVE THE FROGS! Volunteer Mindy Meadows (who flew in from Tennessee) wrote to SAVE THE FROGS! Wetland Coordinator Kathlyn Franco after the construction event:

“It was such an amazing experience! Not only did I get to meet you and learn from you but also Leslie, Emily, Tom, Maura, Neil…so many wonderful people with so much knowledge! We learned things we didn’t even expect….like fixing the equipment road after the wetland was built. Thank you SO much for making it all happen and for saving the frogs!!”

We covered the liner with soil and branches so amphibians can hide and attach egg masses.

Here is an exceptionally cool video of the entire October 3rd, 2016 wetland being built…and condensed into three-minutes:

These wetland projects are vastly important. We have successfully created wetlands that are being used by federally threatened frogs, giving them increased chance of survival, even as their habitats elsewhere are being degraded. More wetlands like these will enable their populations to rebound.

We look forward to sharing more success stories like this! If you agree that Re-Frogging America by building wetlands for threatened amphibians is important, please consider making a tax-deductible donation to SAVE THE FROGS!. In 2017, SAVE THE FROGS! Wetland Coordinator Kathlyn Franco is planning to lead the construction of seven new wetlands - and your financial support will make them possible.

Re-Frogging America in 2017

SAVE THE FROGS! plans to build six wetlands in 2017. Four of the wetlands will be approximately 30-ft diameter and two will be 12-ft diameter. Each wetland takes a full day to build. The large wetlands require heavy equipment (such as an excavator). The small wetlands we will build by hand.

The estimated cost for SAVE THE FROGS! to build a 30-ft wetland is $6,954. This covers the initial site survey, wetland design, coordinating, planning, travel expenses, heavy equipment and equipment operator, building materials, seeds, native vegetation, promotion via our website, newsletter and social media, as well as reporting to funders and partners and a followup site survey.

The estimated cost for SAVE THE FROGS! to build a 12-ft wetland is $3,530. This covers the initial site survey, wetland design, coordinating, planning, travel expenses, building materials, seeds, native vegetation, promotion via our website, newsletter and social media, as well as reporting to funders and partners and a followup site survey.

Thus, the total cost for the SAVE THE FROGS! 2017 wetland program will be approximately $35,582, for which we plan to deliver four large and two small wetlands. Of course we will also to continue to educate, empower, and inspire other frog enthusiasts to build wetlands as well!

We appreciate your financial support to ensure we can build these six wetlands and educate hundreds of volunteers in the process.  You can donate here. Thank you!

Building Wetlands for Endangered Species in Arizona: Part 1

SAVE THE FROGS! Wetland Coordinator Kathlyn Franco writes about her March 2016 trip to save endangered species in Arizona by constructing wetlands and Re-Frogging America!

In February 2016 I assisted wetland expert Tom Biebighauser in re-building a failing wetland. This wetland is extremely important because it is situated in a desert where water is rare. Amphibians and other wildlife depend on these water sources for survival and breeding. This pond in particular is being built to hold water year round to manage for the Gila Topminnow; a federally-listed species of fish. The landowners built this wetland on their property but due to the sandy loam soil type, they are losing too much water directly into the ground and the rest to evaporation. Read on to learn more about this project and the different steps we took to fix this pond! Visit to learn all about wetlands.

Arriving At The Scene (February 22, 2016):

Last night I arrived in Tucson, Arizona surrounded by the iconic Saguaro cactus and, today, I find myself being driven up 3,000 feet in elevation, 45 minutes outside of the city. I leave the big city of Tucson behind in exchange for the mesquite-grassland of Amado, a town with a population of only 295 people. The open land surrounding Amado has the space needed for wildlife movement and we plan to build a large, 90-by70-foot wetland for wildlife to thrive. The wetland will be on private property, a ranch endearingly named TimBuckTwo. Currently, the land where we are to build is barely holding water. In order to protect the federally listed Gila Topminnow and create a water source for wildlife, we want to repair this wetland reshaping the basin with an excavator to give it a slope less than 20%. This will give the wetland a more natural look and create an ecosystem with high biodiversity. We want the wetland to hold water year round for the federally endangered fish and surrounding wildlife, so we plan to make this wetland 8 feet deep in the center.


As we begin to reshape the basin we find a nonnative bullfrog hibernating.

This is a sure sign that amphibians can live in this area when water is available. To ensure the survival of our native amphibian species and our federally-listed Gila Topminnow, we removed this nonnative bullfrog. Once we finished reshaping the basin with the excavator, our volunteers, provided by Sky Island Alliance, helped rake and remove rocks and anything else that can puncture our geotextile liner that holds water.

After we raked the wetland and placed the geotextile with the help of the volunteers, we stretched out the geotextile and staked 12-inch spikes in at the elevation of the future water level. Elevation of the spillway (lower edge) determines the water level and where to stake the spikes. All of these steps took all day! To learn the next steps, please stay tuned.

Frog Friendly Habitat In France

We just received this note from SAVE THE FROGS!' newest member, Hazel Richards:

"Since moving to France, a couple of years ago, my husband and I have been slowly turning our garden into one that is wildlife friendly. We have planted hedges, shrubs, a small copse of hazelnut bushes, a wildflower garden and fruit trees etc. The birds and bats seem to appreciate the increase in insects that now buzz frenetically around the plants throughout the year; As do the large family of fascinating lizards that live amongst the stones in the garden.
