During the winter months they hibernate on the bottom of water bodies that don't freeze. D I E T Leopard frog tadpoles eat plants, algae and the remains of invertebrates and other tadpoles. In Eastern Canada the northern leopard frog is most similar to the pickerel frog. Pickerel frogs have square shaped Adults eat almost anything they can spots, a yellow belly and always have a catch including insects, other brown body colour. invertebrates and sometimes mice or fish. 1 N O R T H E R N L E O P A R D F R O G Lithobates pipiens L I F E C Y C L E : B R E E D I N G F R O G C A L L Northern Leopard Frog breeding occurs in mid to late spring.

The sound is similar to a finger rubbed on a wet balloon. The call is similar to a Pickerel frog but more complex. Egg masses are attached to submerged vegetation. Females can lay up to 7000 eggs but generally lay half this number. Eggs are approximately 1.5 mm in diameter and hatch into tadpoles in 1-3 weeks (mid to late summer) depending on the air and water temperature. By early August the tadpoles turn into For more information visit: adult frogs. www.charlottetown.ca 2.

Amphibian Migrations & Road Crossings Amphibian Identification Guide The NYSDEC Hudson River Estuary Program and Cornell University are working with communities to conserve forests, woodland pools, and the wildlife that depend on these critical habitats. This guide is designed to help volunteers of the Amphibian Migrations & Road Crossings Project identify species they observe during spring migrations, when many salamanders and frogs move from forest habitat to woodland pools for breeding.

They are animals with a secretive nature, and comparatively little is know about their basic life history and natural history. To address this gap, and to obtain the information necessary to manage for this species in areas of decline, I studied the breeding biology of two Crawfish Frog populations during 2009 and 2010.

Our forests, prairies, rivers, swamps and marshes are Mhome to a multitude of toads and frogs, but few people know how many varieties we have, how to tell them apart, or much about their natural history. Studying these animals and sharing their stories with fellow Missourians is one of the most pleasurable and rewarding aspects of our work. Toads and frogs are amphibians—a class Like most of vertebrate animals that also includes amphibians, salamanders and the tropical caecilians, which are long, slender, wormlike and legless. frogs and Missouri has 26 species and subspecies (or toads have geographic races) of toads and frogs. Toads and frogs differ from salamanders by having an aquatic relatively short bodies and lacking tails at adulthood. Being an amphibian means that tadpole stage they live two lives: an aquatic larval or tadpole and a semi- stage and a semi-aquatic or terrestrial adult stage.

Managing Forests for Fish and Wildlife
Wildlife Habitat Management Institute Managing Forests for Fish and Wildlife December 2002 Fish and Wildlife Habitat Management Leaflet Number 18 Forested areas can be managed with a wide variety of objectives, ranging from allowing natural processes to dictate long-term condition without active management of any kind, to maximizing production of wood products on the shortest rotations possible. The primary purpose of this document is to show how fish and wildlife habitat management can be effectively integrated into the management of forestlands that are subject to periodic timber harvest activities. For forestlands that are not managed for production of timber or other forest products, many of the principles U.S. Forest Service, Southern Research Station in this leaflet also apply. Introduction Succession of Forest Vegetation Forests in North America provide a wide variety of In order to meet both timber production and wildlife important natural resource functions.

Frog Raising
COMMERCIAL POSSIBILITIES AND LIMITATIONS IN FROG RAISING While there may be some profit from selling frogs, artificial propa gation of frogs on a commercial basis has not been proved successful. The Fish and Wildlife Service has received thousands of inquiries about frog raising, but to the present time has heard of only two or three persons or institutions claiming any degree of success, so far as intensive frog culture is concerned. Much of the success claimed by a few II frog farms" appears to have been in the sale of breeding stock to would-be frog farmers. The Service has never engaged in frog culture and has never distributed or sold frogs, tadpoles, or frog eggs. Frog farming.--Most of the so-called frog farms, and those that should be least expensive and require the least labor, are simply natural marshy areas or ponds with food and environment suited to the needs of frogs. In such areas the frogs, left to themselves, will thrive and multiply; results may be improved by increasing the shoreline as mentioned below. A pond or swampy area may be stocked with adult frogs, or with eggs. In stocking with adults, better results may be obtained by introducing the frogs in late summer and fall in order that they may become accustomed to their ne~ surroundings before the egg-laying season--April iil the South and Mayor June farther north (in California some species begin breeding in January and February). Smaller species might be hatched to serve as food for the larger edible varieties, but the cannibalistic habit which this suggests dictates a segregation of the commercial species according to size to prevent their eat ing one another.
