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
