This weekend The Wild Center in Tupper Lake is hosting a special symposium that will look at the global and local health of amphibians (frogs, toads, salamanders, newts, etc) and what it means for the Adirondacks and our planet (details below, along with a full list of Adirondack amphibians).
Probably because they lived in two polluted worlds – they are cold-blooded animals that metamorphose from a water-breathing juvenile to an air-breathing adult – amphibian populations around the globe are threatened or extinct. Some scientists believe it’s related to environmental pollutants, development that reduces their habitat, and global warming (which exacerbates pathogen outbreaks) are to blame.
This brings up the DEC’s Amphibian & Reptile Atlas Project (known as the Herp Atlas), a ten year survey (1990-1999) documenting the distribution of New York State’s herpetofauna. Using more than 1,200 volunteers, the project hoped to count 20 species in each survey block (based on 7.5′ topographic quadrangles) – that number was lowered by the end of the project to 15 species in each block – the data is lame, and hasn’t been exploited as far as I can see.
What data there has been made available is here, although I’m not sure why it hasn’t been included in the USGS North American Amphibian Monitoring Program.
Records prior to 1989 were also supposed to be compiled for a historic database, but the online data doesn’t even include 1999’s findings, let alone any historic data or analysis. So all the public really has to work with is a simple map and a series of fact sheets on the state’s amphibians and reptiles.
We have to wonder (no we don’t, we already know) why the Whitetail-deer management effort is so comprehensive, when the the herps are given short-shrift. The fact is that amphibians are experiencing an obvious and serious decline that suggests they may be “toads in the coal mine.” How about at least a Landowner’s Guide for Managing Amphibians?
Here are the details for the Wild Center’s Amphibian Weekend, which is free for members or with paid admission:
July 26 – 11am-12pm: “Amphibians of New York State” in the Flammer Theater with Dr. Glenn Johnson, Professor Biology at SUNY Potsdam and co-author of Reptiles and Amphibians of New York State 12pm-12:30pm: Amphibian encounter with a Wild Center naturalists in the Great Hall. 1pm-2pm: Lecture in Flammer Theater Why Amphibians Matter with Dr. Kevin Zippel, Program Director of Amphibian Ark, a scientific initiative sponsored by the Chicago Zoological Society . The Chicago Zoological Society is leading zoos worldwide in the globally coordinated public awareness campaign entitled “2008 The Year of the Frog.” 2-2:30pm: Amphibian encounter with a Wild Center naturalists in The Great Hall. 3pm-4pm: Children’s Program in The Great Hall with Wild Center naturalists called “Cyclin’ Around the Pond: The Life Cycles of Amphibians in Blue Pond”.
July 27 – 11am-12pm: Get “Up Close with Wild Center Amphibians” in the Flammer Theater with our own amphibian biologist, Frank Panaro. This program will cover the biology of Adirondack amphibians with special glimpses of them under the camera. 12-12:30pm: Amphibian encounter with a Wild Center naturalists in the Great Hall 1pm-2pm: Lecture in Flammer Theater entitled “Conservation of Kihansi Spray Toad” with Dr. Jennifer Pramuk, Curator of Herpetology at The Bronx Zoo. Other topics covered will be global amphibian health and zoo initiatives to protect and conserve amphibians worldwide. 2pm-2:30pm: Amphibian Encounter with a Wild Center naturalists in the Great Hall 3pm-4pm: Family Art Program- “Flippin’ Frogs and Slithery Salamanders”- Origami frogs and salamanders (the frogs can actually flip!).
