Skylands Visitor: Rare Herps

Conserve Wildlife Foundation biologist Allegra Mitchell recently wrote about rare herps for Skylands Visitor’s website. Allegra takes you on a tour through the sometimes weird, always wonderful world of amphibians and reptiles.

As the season eases into milder temperatures at the onset of spring, all manner of creatures stretch their bodies and move more freely, searching for food and mates while they patrol their home turfs. Among these creatures are some of the most rare, interesting, and beautiful animals in the Garden State. Though they often go unnoticed or are misunderstood, reptiles and amphibians are vital to the balance of our fragile ecosystems—and some of them are in pretty big trouble.

Exploration of An Ecosystem That Most People Will Never See

CWF Vernal Pool Walks Connect New Jersey Residents with Rare, Seasonal Marvel

We all know that “April showers bring May flowers,” but the earlier rains of March stir up beauties of a different kind. When the first spring raindrops hit the barely-thawed ground and night falls on the forest, frogs, salamanders, and toads emerge from their winter burrows. These amphibians – the spotted salamanders, wood frogs, spring peepers, and others – are anxious to get to their breeding pools and lay their eggs. The waters that they choose are called vernal pools because they fill with rainwater, snowmelt, and rising groundwater in early spring but then dry up as summer advances. The pools are thus temporary and cannot support fish, meaning fewer predators for the amphibian eggs and young.

In the northeastern United States, vernal pools are home to over 500 species. In New Jersey, these pools are critical habitat for amphibians, reptiles, invertebrates, migratory waterfowl, raptors, and songbirds. All 14 of New Jersey’s frog species use vernal pools to breed and two endangered salamander species breed exclusively in vernal pools, including Cape May’s eastern tiger salamander.

The new generation of amphibians must race to complete metamorphosis and leave the vernal pool before the water does. Under perfect conditions of warm, thawing, nighttime rains, there may be hundreds or even thousands of amphibians moving at once toward the same breeding pool. The darkness and the rain allow them to move stealthily over the landscape, hidden from predators like the owl and raccoon.

 

CWF’s Kelly Triece organized a series of walks through the vernal pools of Waterloo Village in Sussex County, New Jersey, and showed residents the unexpected creatures swimming in the pool’s shallow waters. Kelly led the exploration of an ecosystem that most people will never see! Participants listened to the songs of Spring Peepers and discovered salamander eggs, fairy shrimp, and other unique creatures as the evenings set in. Here are photos from her walks:

Road Closed: Salamander Crossing

Road Closures Help Amphibians Migrate to Vernal Pools to Breed

Conserve Wildlife Foundation is excited to celebrate Amphibian Awareness Month during March 2015! Follow us on social media and be sure to check your email (sign up for our list) for weekly stories on the amphibians of the Garden State and our work to protect them.

On the night of March 14, Conserve Wildlife Foundation Communications Coordinator Lindsay McNamara attended the first closure of Beekman Road this season. Beekman Road, in East Brunswick, New Jersey, is closed to traffic about two or three nights for six to twelve hours each spring by Friends of the East Brunswick Environmental Commission (Friends of EBEC). Friends of EBEC organizes these road closures to maintain local biodiversity.

 

In the woods on either side of Beekman Road, vernal pool habitat exists. Vernal pools are temporary woodland ponds that fill with water during the winter and spring and dry out in the summer. These vernal pools are extremely important for a number of amphibians in the area. Spotted salamanders, wood frogs, green frogs, spring peepers, Fowlers toads and chorus frogs all rely on the vernal pools for breeding.

 

Some amphibians, like spotted salamanders and wood frogs are entirely dependent on the vernal pools for breeding. They leave their winter hibernation spots in upland forests and migrate (often in large groups) to the vernal pools. Research suggests that these species follow the same migratory paths each year, often traveling distances of as much as 1,000 feet from their hibernation spots.

 

At the vernal pool, mating occurs, eggs are deposited by the females, and the adults leave the habitat and venture to the surrounding woods. The adults spend their summer in these wooded areas before slowly retreating back to their winter hibernation areas, and the natural cycle begins again.

 

Unfortunately, the migrating amphibians need to cross Beekman Road to get from their hibernating spots to their vernal pool breeding grounds. Road kills during this journey significantly reduce salamander and frog populations and can lead to local extinctions at breeding ponds.

 

Friends of the East Brunswick Environmental Commission has worked together with a number of partners to close Beekman Road to traffic during nights when amphibian migration is extremely likely. These road closures help protect migrating salamanders and frogs as they move across Beekman Road to their breeding vernal pools.

 

Friends of EBEC consider a number of variables before they decided to close the road. A wide range of factors trigger salamander migration including the amount and timing of rainfall, the date, the temperature of the air, the temperature of the ground, the availability of open water on the vernal pools, the depth the salamanders are migrating, soil moisture and many others. Interestingly, studies have shown that males typically migrate first and arrive at the vernal pools before the females. It seems females need a higher average air temperature to stimulate their movement than the males.

 

Volunteers are encouraged to come on these rainy nights to help the amphibians cross the road. Bring your friends, your family and don’t forget a flashlight, to the next road closure of the season! Updates are posted on the Friends of the East Brunswick Environmental Commission’s blog.

 

These road closures are a great way to protect local biodiversity and educate New Jersey residents about wildlife in their state. Conserve Wildlife Foundation, in partnership with the New Jersey Division of Fish & Wildlife’s Endangered and Nongame Species Program, lead a number of Amphibian Crossing volunteer programs across New Jersey.

Protecting Eastern Tiger Salamanders in New Jersey

Tuesday, February 3rd, 2015

 

By: Lindsay McNamara, Communications CoordinatorETS close_up_12.2014

Conserve Wildlife Foundation proudly partners with Atlantic City Electric to help protect New Jersey’s rarest amphibian, the Eastern Tiger Salamander. The survival of Eastern Tiger Salamanders is threatened by sea level rise, over-development of critical habitat and climate change.

 

We are working together to build a vernal pool along a portion of Atlantic City Electric’s transmission right-of-way in Cape May County. Vernal pools hold water in the winter and spring, but dry out during the summer months. Since fish cannot live in vernal pools, salamander eggs are not in danger of being eaten. We are hopeful that these ideal breeding conditions will aid Eastern Tiger Salamander recovery over time.

 

Last Friday, Conserve Wildlife Foundation biologists and other state biologists took Eastern Tiger Salamander egg masses from a productive pool and placed them into the new vernal pools.
