HUMPHRIES GOVERNOR DIRECTOR Michigan Frog and Toad Survey 2009 Data Summary There were 759 unique sites surveyed in Zone 1, 218 in Zone 2, 20 in Zone 3, and 100 in Zone 4, for a total of 1097 sites statewide. This is a slight decrease from the number of sites statewide surveyed last year. Zone 3 (the eastern half of the Upper Peninsula) is significantly declining in routes. Recruiting in that area has become necessary. A few of the species (i.e. Fowler’s toad, Blanchard’s cricket frog, and mink frog) have ranges that include only a portion of the state. As was done in previous years, only data from those sites within the native range of those species were used in analyses. A calling index of abundance of 0, 1, 2, or 3 (less abundant to more abundant) is assigned for each species at each site. Calling indices were averaged for a particular species for each zone (Tables 1-4). This will vary widely and cannot be considered a good estimate of abundance. Calling varies greatly with weather conditions. Calling indices will also vary between observers. Results from the evaluation of methods and data quality showed that volunteers were very reliable in their abilities to identify species by their calls, but there was variability in abundance estimation (Genet and Sargent 2003).

  • Quick Guide to Calling Amphibians Reference: Maine’S Amphibians and Reptiles
    Quick Guide to Calling Amphibians Reference: Maine’s Amphibians and Reptiles Spring Peeper (Pseudacris crucifer): One of Maine’s most widespread species and our smallest frog, measuring under an inch and a half, with a dark, imperfect cross or “X” pattern on the back. It has relatively smooth skin and is generally brown to gray with some yellow on the throat. A full chorus of these tiny frogs can be heard up to a half-mile away; each male makes a shrill, pure, high-pitched breeding call. Wood Frog (Rana sylvatica): The first frog to emerge in the spring, the wood frog can tolerate cold and even freezing temperatures for short periods of ©USGS NEARMI time. It has a dark mask over and below each eye ©USGS NEARMI and is otherwise dark red or tan. Wood frogs are widespread in Maine but limit their breeding generally to temporary or vernal pools. The wood frog’s call sounds like the quack of a duck. ©James Hardy ©James Hardy American Toad (Bufo americanus): Maine’s only toad, the American toad has dry, bumpy skin and is largely terrestrial, going in water only to breed and lay eggs. Its call is a high, musical trill that can last 30 seconds or more. Northern Leopard Frog (Rana pipiens): Apparent declines in the population make the northern leopard frog a species of “Special Concern” in the state of Maine. The leopard frog and its close cousin the pickerel frog are the only frogs in Maine with distinct spots. The leopard frog has two to three unevenly spaced rows of irregular oval spots on its back.

  • Kermit the Frog
    written and illustrated by Mrs. Shellenberger’s First Graders Stony Point School April 2006 We dedicate this book to Jerry Pallotta who wrote the greatest books, Mary Lou Lundgren who helped us with art, research and writing, and to all our friends and families. How We Did It! We were reading the Jerry Pallotta alphabet books, The Yucky Reptile Alphabet Book and The Icky Bug Alphabet Book and wondered about making our own alphabet class book. Maysn brought tadpoles for our class and Ms. Shellenberger thought frogs were really cool. We got books from the library and our own class library and brainstormed a list of all the frogs we could find. We never knew there were so many kinds of frogs. We found out a lot of information from the computer. Ms. Shellenberger made us a special research process log to write and draw in. We drew the red-eyed tree frog with MaryLou Lundgren and figured out all the frog parts. We painted frogs on the computer, too. First, we made the outline and then we colored them. We found a dead dried-up frog in the Japanese Garden. It was interesting to see it up close. We used a magnifying glass. We used the magnifying glass to look at the tadpoles, too, so we could sketch them. The tadpoles grew pretty slow. We took pictures of them for the class web page. After we checked out all the books, we decided which frog we wanted to study more. We drew them on the cover of our process log using colored pencils.

    AN EDUCATOR’S GUIDE TO FROGS K-6 Author: Terra Brie Stewart Koval, [email protected] Design & Illustrations: Rost Koval, [email protected], www.mangobonz.150m.com Editor: Neala MacDonald Frogwatch Illustrations: Wallace Edwards, courtesy of the Toronto Zoo This guide has been written by Terra Brie Stewart Koval and designed by Rost Koval through a Science Horizon's Grant with additional support from the Ecological Monitoring and Assessment Network Coordinating Office. This teachers guide is free from copyright when used for educational purposes. If reproduced we ask that you credit the author and the Ecological Monitoring and Assessment Network Coordination Office. DEAR EDUCATOR, Throughout most of history, people have not regarded reptiles and amphibians with high opinion. In fact the 18th century Swedish botanist and zoologist Carolus Linnaeus, famous for his classification system, presented a very strong example of the prevailing attitude toward reptiles and amphibians: "These foul and loathsome animals are abhorrent because of their cold body, pale colour, cartilaginous skeleton, filthy skin, fierce aspect, calculating eye, offensive smell, harsh voice, squalid habitation, and terrible venom; and so their Creator has not exerted his powers to make more of them." Although this attitude may still be representative of many people’s impressions of snakes, it seems that for the most part, our attitude towards frogs has grown to be a little more civilized—or at least it remains so in our children. Children are fascinated by frogs—and with good reason. They are cute, they are easily caught, they make cool sounds, and they have been found in abundance (although their decline is the whole reason programs like FrogWatch have come into existence).

  • Creating Frog Friendly Landscape Ponds
    Creating Frog Friendly Landscape Ponds Frog Habitat - Wisconsin is home to 12 species of frogs, all of which require standing water for breeding. Some species, such as the wood frog, can begin breeding as early as March in a warm year while others, such as the Blanchard’s cricket frog, breed later in the summer. The green frog, American bullfrog, and mink frog typically (although not always) require large permanent waterbodies for breeding because their tadpoles take 1-2 years to develop; however the remaining 9 frog species in Wisconsin routinely utilize smaller waterbodies for breeding, such as landscape ponds. For additional information on Wisconsin’s frogs, please visit the Department of Natural Resources web site: dnr.wi.gov/topic/WildlifeHabitat/herps.asp?mode=table&group=Frogs. Pond Recommendations - If you are considering creating a landscape pond and would like to make it as frog friendly as possible, please follow the recommendations below. You will not need to add frogs to the pond once you have it completed, they will find new suitable habitat very quickly, often in as little as 1 year! With a smaller pond and fairly uniform habitat nearby, you can expect 1-4 species, however with a larger pond and a variety of habitats nearby, you could expect up to 6-8 species throughout the year. Different frog species call during various times of the year, so frogs in your pond may spread out their calling throughout the spring and summer. The size (surface area) of the pond is not extremely important (although typically the larger the better), however, irregular borders or curvature to the shape of the pond are beneficial and create a variety of microhabitats and areas of shelter.
