Calling Amphibian Monitoring Project (CAMP)

The Conserve Wildlife Foundation of NJ coordinates the statewide Calling Amphibian Monitoring Program (CAMP). The object of this program is to assess the distribution, abundance, and health of New Jersey’s amphibians. This is part of a larger initiative called the North American Amphibian Monitoring Program (NAAMP) and the data collected in New Jersey will be submitted into the National database.

Each of the 16 species of frogs and toads in New Jersey has a unique vocalization or “call” that can be heard during their mating season.

Here’s a list and call quiz of the Frogs in New Jersey:
Eastern Spadefoot (Scaphiopus holbrookii)
American Toad (Anaxyrus americanus)
Fowler’s Toad (Anaxyrus fowleri)
Northern Cricket Frog (Acris crepitans)
Pine Barrens Treefrog (Hyla andersonii)
Green Treefrog (Hyla cinerea)
Gray Treefrog (Hyla versicolor)
unknown gray treefrog species (Hyla chrysoscelis/versicolor)
Cope’s Gray Treefrog (Hyla chrysoscelis)
Spring Peeper (Pseudacris crucifer)
New Jersey Chorus Frog (Pseudacris kalmi)
American Bullfrog (Lithobates catesbeianus)
Carpenter Frog (Lithobates virgatipes)
Green Frog (Lithobates clamitans)
Wood Frog (Lithobates sylvaticus)
Southern Leopard Frog (Lithobates sphenocephalus)
Pickerel Frog (Lithobates palustris)

The Amphibians that are listed as Endangered or Threatened in New Jersey:

Endangered Amphibians
Salamander, blue-spotted – Ambystoma laterale
Salamander, eastern tiger – Ambystoma tigrinum
Treefrog, southern gray – Hyla chrysocelis

Threatened Amphibians
Salamander, eastern mud – Pseudotriton montanus
Salamander, long-tailed – Eurycea longicauda
Treefrog, pine barrens – Hyla andersonii

Volunteers participating in the CAMP project conduct roadside surveys (after dusk) for calling amphibians along designated routes throughout the state. Each 15-mile route is surveyed three times during the spring (March, April & June), during the given four week period. Each route has 10 stops, where you stop, listen and record for 5 minutes. A structured protocol is followed to determine which nights to survey, how long to survey, which species are calling, and how to estimate the total number of individuals calling at each site. All volunteers receive a Calls of NJ Frogs and Toads, CD with which to familiarize themselves with the calls.

The results of these surveys will provide ENSP (Endangered and Nongame Species Program) and the United States Geological Survey with valuable data on the calling amphibian populations in New Jersey. Because each route will be surveyed at the same time and for the same amount of time, routes can be directly compared within a given year and between years. This allows for trends in populations to be identified over time and if needed steps may be taken to protect these populations in the near future.

Enhancing Your Eco-Friendly Garden to Attract Frogs and Toads

Guest post by Jeriann Watkins

There are a few different reasons you might want frogs and toads in your garden. They do a great job of keeping bugs away. They’re fun to watch after rainstorms when they hop in puddles and through wet grass. They serenade you to sleep at night (ok, that may be a bad thing, depending on whether you like croaky serenades).

As much as you may like frogs and want them in your yard, you should never take it on yourself to place them there. Frogs do not do well when removed from their habitats. Also, you want to be sure that your garden is home to native species, not invasive ones that will do more to harm your private ecosystem than help.

The best way to attract any wildlife to your garden is to emulate what the land would do itself. Trees, shrubs, bushes, and vegetation that would normally grow in your area are most likely to attract native insects, which will in turn attract frogs and toads.

To the human eye, frogs are pretty unassuming. Some people don’t like the slimy appearance. Whatever your opinion, you probably don’t see them as vicious. But they are fierce predators with large appetites, so if you have the environment and the bugs, they will come.

Choose plants that retain moisture and offer shade. Frogs love cool damp environments, mostly out of necessity. Mulch and compost piles are also great for attracting frogs. They’re a).moist b). full of bugs and c).dark.

There are a lot of plants that are poisonous to frogs. If you have a vegetable garden, you’ll want to avoid planting these items near your pond or areas where frogs are likely to congregate:

Eggplant, Rhubarb, Snowpeas, Potatoes

For landscaping and flower gardens, you’ll want to avoid:

Honeysuckle, Azalea, Hydrangea, Daffodils, Hyacinth

For more info, check out this more exhaustive list of plants that are poisonous for amphibians and reptiles.

Frogs and toads are important for the environment, and are great for maintaining healthy eco-systems. While displacing wildlife to improve your garden will always backfire, you can enhance your garden and landscape to attract creatures that do need food sources and shelter. It’s a symbiotic relationship in that you’re helping them so they can help you.

Protecting the Unique Frogs of Andasibe, Madagascar

Guest post by
Devin Edmonds,
Amphibian Conservation Director, Association Mitsinjo

It doesn’t get much better than a going into the forests of Andasibe at night. There are leaf-tailed geckos, mouse lemurs, sleeping chameleons, and frogs. Lots of frogs. More than 100 different species, in fact, which have been identified in the surrounding forests. This is more than a third of all described frog species on the island.

Most of these frogs are nocturnal, but a few are also active during the day, like the Critically Endangered golden mantella (Mantella aurantiaca), which is only found in a small area near Andasibe in east-central Madagascar.

The conservation organization Mitsinjo works in the area around Andasibe, and is composed of 53 members of the community.

Our activities include:

Habitat management
Research
Nature-based tourism
Reforestation
Captive breeding
Environmental education

A group of our projects are targeted specifically at monitoring and addressing the threats our unique local frog species face. This includes the development of Madagascar’s first biosecure captive breeding facility capable of establishing assurance survival colonies of threatened amphibians.

Additionally, we conduct surveys to monitoring for declines and population changes. This activity compliments participation in a nation-wide early detection plan for the chytrid fungus Bd, the devastating pathogen contributing to alarming amphibian extinctions around the world. Fortunately, so far we have not detected Bd in Andasibe and reports elsewhere in Madagascar remain highly doubtful and unconfirmed.

Recently, Mitsinjo joined forces with the NGO Madagasikara Voakajy to contribute to the national conservation strategy for the golden mantella. Each month, we monitor three breeding sites at Torotorofotsy Wetland. This area is under tremendous pressure from artisanal gold mining, slash-and-burn agriculture, and charcoal production. Our habitat patrols help to ensure the breeding sites for this highly threatened amphibian remain intact.

Herps Alive! A Reptile Rescue Herpetologist Writes About Frogs

Guest Post by Keith Gisser

I know what you are thinking.

Why is a reptile rescue guy writing about frogs? They aren’t reptiles. And captive frogs don’t need to be rescued. Gators, boas, pythons, maybe even big monitor lizards and iguanas, sure. But frogs?

Herps Alive! The Interactive Reptile and Amphibian Experience, is a traveling educational herpetology program and display. We have presented in 36 states (primarily at college campuses, but also at libraries, festivals elementary and high schools). Now in my fifties, I did my first paid program at age 17, and now my daughter a degreed Interpretative Naturalist, and my son, a marketing whiz, often travel and help me. We offer display programs and interactive lectures as well as classroom sessions, and have presented an estimated 3,000 programs since we started (we have worked some “real” jobs here and there).

As your reputation builds, you start getting calls to adopt animals. Usually they are pets that people can’t keep. Sometimes they are police seizures or animals from other unfortunate situations. We have always accepted these animals in an effort to keep a good relationship with the museums, nature centers and law enforcement officials who contact us.

But in the last year or so, the rescue mission has taken on a life of its own. We have been asked to take in dozens of animals. And for the first time, we began rehoming a few. As a result we are spinning off our rescue mission and working on moving it to a separate location, as we turn it into a charitable foundation.

But what about the frogs?

I have been fascinated with frogs my entire life. My career as a herpetologist probably began at age nine when I caught a toad. I brought him home in a rinsed out pickle jar. (That was 45 years ago when such behavior was acceptable. At the time they were also in the genus Bufo, not Anaxyrus) I have bred several species of frog in captivity and always include a discussion of metamorphosis in my educational programs.

Right now we have three frogs among our 150 animals. Our Southern Toad (Anaxyrusterrestris) was living in a Carolina classroom after a student had brought him. He had been in captivity for too long to be released, so when we came in to do a program, the teacher asked if we could take him. Known just as The Toad, he eats crickets and small worms, as well as waxworms.

Beatrice is an African Clawed Frog (Xenopuslaevis) who was raised from a small size by my son’s ex-girlfriend. When she moved into a new home, she asked us to take her on. Beatrice was raised in a 10 gallon aquarium. When we tried to move her to a larger one, she went off feed and seemed generally unhappy. So back into the ten she went even though it really is too small for her. She loves her goldfish and nightcrawlers and eats anywhere from 10-30 a week. Unfortunately, her relatives have been taking a bad rap lately as they have been identified as the culprits that carried of the dreaded chytrid fungus. It’s not really their fault. In everywhere except their African home, they were used as lab animals. They were used as part of a pregnancy test. The problem is not with them carrying the fungus, but rather with the irresponsible people who have released them outside their normal environment.

Finally, there is Poncherello Pegone Pixiefrog, our African Bullfrog (Pyxicephalusadsperus). “Ponch” is named for the mayor on the cartoon My Gym Partner’s a Monkey., who is also a Pixie, or African Bullfrog. We adopted him from a breeder because he appears to be blind in one eye and the breeder did not want him. Ponch eats thawed mice off tongs, usually one or two a week. He is also a regular in our programs, having traveled to 14 states since we got him two years ago. While our other frogs are kept in our entrance hallway (Our facility is not air conditioned), Ponch loves the heat and his aquarium is kept in our snake and lizard room, where the high ambient temperature helps him with digestion.

We hope to see you some time in the future…

About Keith Gisser:

Keith caught a toad (Anaxyrus ssp) when he was nine and his herpetology career began. He has presented Herps Alive! an award-winning, nationally recognized interactive reptile and amphibian program based in Ohio, at over 170 college campuses and hundreds of other venues in 39 states.

Gisser, who has been a herpetology educator for over thirty years and currently maintains about 140 reptiles, amphibians and crocodilians, nearly all of which are adoptions or rescues, about half of which are used in his programs. The rescue and adoption mission has taken more and more of his time and efforts in recent years and will soon be “spun off” as the Herps Alive! Foundation, which is in the process of seeking non-profit status and accreditation as a rescue.

SALAMANDERS IN CRISIS! An Overview of Why Salamander Conservation is Needed

Guest blog by Matt Ellerbeck, founder of Save the Salamanders

Although they are rarely given much thought, and often overlooked when they are, salamanders are in a terrible crisis. Around half of all the world’s salamander species are listed as threatened by the International Union for Conservation of Nature (IUCN). These species are all facing a high risk of extinction. A further 62 species have been designated as near-threatened with populations rapidly dwindling. This means they are quickly getting closer to threatened status and to the brink of extinction. Sadly for some salamanders it is already too late, as both the Yunnan Lake Newt (Cynops wolterstorffi) and Ainsworth’s Salamander (Plethodon ainsworthi) have already gone extinct.

Salamanders have been on the earth for over 160 million years, and the terrible state that they now find themselves in is due to the detrimental acts of humans. Even those species that are not experiencing population declines deserve attention and conservation to ensure that they remain healthy and stable.

One of the biggest issues affecting salamanders is the loss of their natural habitat. Many areas that were once suitable for salamanders to live in have now been destroyed for developmental construction and agriculture. Habitats of all kinds are being lost at an alarming rate. Wetlands are drained, forests are logged and cut down, and waterfronts are developed. Salamanders are literally losing their homes and they are losing them rapidly. The expansion of urban areas threatens the suitable habitats that still remain.

Where natural habitats do still exist, they are often fragmented or degraded. Fragmentation occurs when healthy areas of habitat are isolated from one another. These fragmented areas are known as habitat islands. Salamander populations are affected since gene flow between the populations is prevented. This increases the occurrence of inbreeding, which results in a decrease in genetic variability and the birthing of weaker individuals.

Fragmented populations where inbreeding occurs often ends in a genetic bottleneck. This is an evolutionary event where a significant percentage of the population or species is killed or otherwise prevented from reproducing. Habitat fragmentation is also harmful because it often eliminates crucial requirements in the area which are critical to the survival of salamander populations. Such areas include spaces that can be utilized for thermoregulation, prey capture, breeding, and over-wintering. Without such habitat requirements populations dwindle.

Breeding sites, often in the forms of vernal pools are particularly important. The loss of such areas in the form of habitat destruction can negatively affect the entire population and its reproductive output. According to the Committee on the Status of Endangered Wildlife in Canada (COSEWIC), there is some evidence that certain salamander species have individuals that return to the pond in which they were born once they reach maturity. Therefore, destruction of a breeding pond may result in loss of the entire population returning to that site. Habitat complexity is also important as it offers shelter to salamanders from both predators and human persecution.

Degradation occurs when the natural habitat has been altered and degraded to such a degree that it is unlikely that any remaining salamanders species would be able to survive. Developments and agriculture near fragmented habitats put salamanders at serious risk. As amphibians, salamanders have extremely absorbent skins. Industrial contaminants, the introduction of sedimentation into waterways, sewage run off, pesticides, oils, and other chemicals and toxic substances from developmental construction sites and human settlements can all be absorbed by salamanders. This can quickly lead to deaths. They can also cause widespread horrific deformities to occur. A study conducted at Purdue University found that out of 2,000 adult and juvenile salamanders 8 percent had visible deformities.

According to Save The Frogs, Atrazine (perhaps the most commonly used herbicide on the planet, with some 33 million kg being used annually in the US alone) can reduce survivorship in salamanders. Many products are sold with the claim that they are eco-friendly. However, these should be viewed with caution. For example, according to N.C Partners in Amphibian and Reptile Conservation, Roundup and many other surfactant-loaded glyphosate formulations are not labeled for aquatic use. When these formulations are applied to upland sites according to label instructions, the risk to surfactant-sensitive species is considered low. While this may be the case for fish it does not necessarily apply to amphibians. Salamanders that breed in water also routinely use non-aquatic areas and could easily be exposed to glyphosate formulations that contain harmful surfactants through direct application and not just incidental drift.

Habitat destruction and degradation can also effect the availability of prey items, causing unnatural declines in appropriate food sources.

Habitats are often isolated and cut off from one another by the roads and highways that now run through them. Countless numbers of salamanders are killed on roads and highways every year when they are hit by vehicles. Salamanders that are migrating to breeding and egg-laying sites often must cross over roads to reach such areas. Here many of the mature members of the breeding population are killed. Removing members of the breeding populations greatly limits reproductive output, this makes it incredibly hard for salamander numbers to rebound.

Roads present an additional problem because they represent a form of habitat loss. The roads that run through natural areas also fragment the existing populations, drastically making them smaller in size. This limits the gene flow and genetic diversity between the isolated populations on either side and this greatly increases the chances of extirpation. When salamanders attempt to cross roads to travel between the populations, or to critical breeding/birthing sites it greatly increases their chances of being hit and killed by vehicles.

The Wetlands Ecology and Management (2005) population projections for spotted salamander (Ambystoma maculatum) life tables imply that an annual risk of road mortality for adults of greater then 10% can lead to local population extirpation. Unfortunately, it is estimated that mortality rates can often be as high as 50 to 100%, which means populations are at extreme risk of extirpation and extinction due to road mortality. Wyman (1991) reported average mortality rates of 50.3 to 100% for hundreds of salamanders attempting to cross a paved rural road in New York State, USA. Given that this figure pertains to a rural area from over a decade ago, it is fair to assume that even higher mortality rates occur as their has been in increase in cars and roads over the years. Reducing road mortality is paramount to preserving salamander species.

Being hit and killed by vehicles is not the only threat that roads create for salamanders. Chemical run-off from vehicles contaminate roadside ditches and pools. These sites are often utilized by salamanders for breeding and birthing. According to Steven P. Brady (2012) survival in roadside pools averaged just 56%, as compared to 87% in woodland pools. Thus, an average of 36% fewer individual embryos survived to hatching in roadside versus woodland pools.

Salamanders are also threatened when they are harvested from the wild. Salamanders are taken for the pet trade, for food markets, and for use as fishing bait.

There is much about salamanders that scientists do not know. Aspects of the biology, ecology, and lifestyles of many species is a mystery. This undoubtedly means human interference is negatively affecting salamanders in ways in which we don’t even know. The intricate relation between all species and the vital roles they play within eco-systems is also being altered. Such alterations can have serious consequences to not just salamanders, but many other animals as well (including humans).

Eco-Interview: Matt Ellerbeck, Save the Salamanders

In this post, we are pleased to feature Matt Ellerbeck, a salamander advocate and conservationist, who created the Save the Salamanders project.

Matt Ellerbeck, aka The Salamander Man, is a man with a mission: he is striving to raise awareness of the threats that salamanders face, and to educate people on effective actions that they can take to help alleviate these threats. The actions include behavioral changes, land stewardship, and habitat management efforts. To bring his message of salamander conservation and protection to the public, Matt utilizes several platforms: media appearances, awareness campaigns, social networking, the distribution of informative fact sheets, and educational presentations/lectures.

Matt also aims to help salamanders by diligently collecting observational records of these animals in the wild. These records are sent to various organizations to help gain a better understanding of salamander populations, ranges, and habitats.

He hopes that through awareness and education, people will develop a sense of empathy and concern for salamanders, and in turn will have a desire to become active in their recovery. For those who do want to contribute to the conservation & protection of salamanders, his site contains much information on how to become active.

As Matt describes his mission:

Everything that I do, I do because I sincerely believe it will help contribute to the conservation & betterment of salamanders, which is my ultimate goal and ambition! Salamanders are the focal point of my life. There is not a day that goes by that I am not doing something salamander related, whether it’s presenting educational lectures on salamander conservation, writing articles, giving interviews, or collecting observations of salamanders in the wild. When I am not doing such activities I am planning and prepping for such efforts. A good portion of every day also goes towards the care of the many salamanders that I live with. These salamanders take turns accompanying me during my lectures and presentations to act as education animals and ambassadors for their kind.

Below is a video interview with Matt in which he discusses his mission:
