Amphibian Night (25-Feb-2017)


With the temperatures as high as they were and rains coming in, I knew there would be amphibians coming out somewhere in Eastern PA. I arranged an outing with friends Andrew Curtis, Paul Guris and Tyler Sacks to go out looking for the first amphibians of the year around their area. I live too far north and I knew in my area it would still be some time before amphibians were out. To my surprise when we turned onto the road nearing our destination there were signs with lights flashing stating that volunteers were moving amphibians across the roads. Then when we got to the parking lot there were about thirty or so students with teachers and other adults in crossing guard uniforms. It was the biggest crew I had ever seen to move the little critters across. During rain events in spring several species like the Wood Frog above make there way to temporary pools to breed. These pools fill with water in the winter and spring and generally dry up by the end of summer. This means they lack certain predators like fish, giving amphibians a safer alternative to lay their eggs in. On their annual journey to these ponds many amphibians have to cross roads and on some nights there can be high mortality rates. Volunteers moving them across help lower the number of mortality due to traffic and help to preserve these species into the future.   


Since there were so many volunteers we did not spend any time on the roads and instead went to check out the pools. By this point the rain had stopped and there was not much activity. A few Wood Frogs had made it to the pools, but were not in the numbers I had hoped. 


This photo was taken in an artificial pond before we headed out. It is a Green Frog and it seemed a bit early for them to be out. We did not find any at the pools that we visited. 


On the way to the pools we did see some Spring Peepers on the trail and on rocks on the trailside. They were just making there way to the pools and none were yet calling. 


We only found two Spotted Salamanders. On a good night they would be seen in the hundreds at this location. Both were males and the lack of amphibians in general told us that it was still a bit too early for them moving in large numbers. The volunteers must have found the same thing on the roads, all the cars were gone by the time we got back to the parking lot. 


I did remove some trash from the trail and from the pools themselves. Trash items like bottles and cans, can potentially trap and lead to the death of certain amphibians. If you see trash in a waterway, please help out and remove it.

Amphibians on the Move (24-Feb-2016)



Wood Frog (Lithobates sylvaticus)
Last night I was sure the heavy rains and warmer temperatures would have some of our native amphibians on the move. There were not many, but I did find a couple species. So, where are they going and why are they out? The two frog species you will see in this post are spring breeders. Both emerge from their overwintering spots and make their way to vernal pools or other wetland areas. Vernal pools are depressions that fill with snow in the winter, rain in the spring and only retain water for a limited time. Since the pools do dry up they offer a safer alternative for egg laying and larval survival for amphibians. The reason being the lack of predators such as fish, which could quickly consume both adult and larval stage amphibians. 

Spring Peeper (Pseudacris crucifer)
If the warm temperatures return, soon the sounds of both Wood Frogs and Spring Peepers will echo from their wetland breeding areas. With both of these species it is generally the males who make it to the pools first and they will be the ones making the vocalizations you may hear.

Keep these little critters in mind at this time of year. Especially when it rains. They can be traveling a good distance to get to their breeding sites and many times there are roads in the way. Amphibians don't fair too well against a car and there are many casualties as they try to cross. Help them out by trying to avoid them, because they do not have a chance at getting out of your way in time.


Of course there was trash when I was slogging through the woods. I picked up a handful of items, the areas I went to were fairly clean.

There are very strict laws regarding amphibians in Pennsylvania. Before you go out on a slogging adventure yourself, you should make sure to know the rules and regulations. If you are over 16 you should have a fishing license on you, even if you are just going out to observe them.

You too can help with taking out the trash! If you get out hiking take a grocery bag with you, give it a second use and fill it with trash while you are out! Every bit helps. You can also help contributing to this project here: Help Fund Taking Out the Trash
