RCN NE Terrapin Conservation Strategy
The Northern Diamondback Terrapin (Malaclemys terrapin terrapin) in the Northeast United States: A Regional Conservation Strategy Prepared by: Stephanie Egger, Wildlife Biologist Conserve Wildlife Foundation of New Jersey, Inc. with Contributions from the Diamondback Terrapin Working Group Prepared for: Northeast Association of Fish & Wildlife Agencies Northeast Regional Conservation Needs Grant Program 2016 Made possible by State Wildlife Grants and funded by the Northeast Regional Conservation Needs Grant Program. REGIONAL CONSERVATION NEEDS GRANT PROGRAM The Northern Diamondback Terrapin (Malaclemys terrapin terrapin) in the Northeastern United States: A Regional Conservation Strategy was supported by State Wildlife Grant funding awarded through the Northeast Regional Conservation Needs (RCN) Grant Program (RCN Grant 2013-02). The RCN Grant Program joins thirteen northeast States, the District of Columbia, and the U.S. Fish and Wildlife Service in a partnership to address landscape-scale, regional wildlife conservation issues. Progress on these regional issues is achieved through combining resources, leveraging funds, and prioritizing conservation actions identified in the State Wildlife Action Plans (SWAPs).

Saving the Diamondback Terrapin
Disney Worldwide Conservation Fund Allows Teachers to Broaden Awareness of the Plight of the Diamondback Terrapin Maggie Dugan: Upper Township Elementary School Jane Krajewski: Quinton Township School Mary Lyons and Lynn Tyskas: Millville Public Schools Our Mission • Gain greater insight into the Terrapin Conservation Project through direct participation with scientists/interns at the Wetlands Institute • Create lessons and activities that can be used throughout the state (and beyond ) to help enlighten others about the terrapin crisis • Provide instruction about the diamondback terrapin at upcoming conferences and disseminate our units to help enhance core standard teaching by incorporating terrapin education within objectives that are already in place in the classroom SAVING THE DIAMONDBACK TERRAPIN Jane Krajewski Quinton Township Elementary School ISN’T SHE CUTE? Diamondback terrapins are the only turtles that live in brackish (a mix of salt and fresh) water. Terrapin Fast Facts! • Females are usually bigger than males. Do you know why? •Females are larger because they are responsible for carrying the eggs. •They also have smaller tails that don’t get in the way when laying the eggs. • Females leave the water to nest above the high tide line. • They lay about 8-12 eggs. • Females will dig a nest with their back leg. • This plaster mold shows the size and shape of a nest. Egg chamber WHY IS THE FEMALE TERRAPIN MORE ENDANGERED? • Most turtles that cross the road are females. • Females enter the roadway because they are looking for suitable nesting sites. Because males do not have to do this, they are usually not the ones to get hit by cars. -
AN INTRODUCTION to Texas Turtles
TEXAS PARKS AND WILDLIFE AN INTRODUCTION TO Texas Turtles Mark Klym An Introduction to Texas Turtles Turtle, tortoise or terrapin? Many people get confused by these terms, often using them interchangeably. Texas has a single species of tortoise, the Texas tortoise (Gopherus berlanderi) and a single species of terrapin, the diamondback terrapin (Malaclemys terrapin). All of the remaining 28 species of the order Testudines found in Texas are called “turtles,” although some like the box turtles (Terrapene spp.) are highly terrestrial others are found only in marine (saltwater) settings. In some countries such as Great Britain or Australia, these terms are very specific and relate to the habit or habitat of the animal; in North America they are denoted using these definitions. Turtle: an aquatic or semi-aquatic animal with webbed feet. Tortoise: a terrestrial animal with clubbed feet, domed shell and generally inhabiting warmer regions. Whatever we call them, these animals are a unique tie to a period of earth’s history all but lost in the living world. Turtles are some of the oldest reptilian species on the earth, virtually unchanged in 200 million years or more! These slow-moving, tooth less, egg-laying creatures date back to the dinosaurs and still retain traits they used An Introduction to Texas Turtles | 1 to survive then. Although many turtles spend most of their lives in water, they are air-breathing animals and must come to the surface to breathe. If they spend all this time in water, why do we see them on logs, rocks and the shoreline so often? Unlike birds and mammals, turtles are ectothermic, or cold- blooded, meaning they rely on the temperature around them to regulate their body temperature. -

Diamondback Terrapin Malaclemys terrapin Contributors: DuBose Griffin, David Owens and J. Whitfield Gibbons DESCRIPTION Taxonomy and Basic Description The diamondback terrapin is a small, long-lived estuarine turtle endemic to coastal marshes, estuarine bays, lagoons and creeks ranging from Cape Cod, Massachusetts to the Gulf Coast of Texas. Currently, there are five (Hartsell 2001) or seven (Ernst et al. 1994) subspecies. More recently, Hart (2004) identified six management units. The subspecies found in South Carolina is Malaclemys terrapin centrata. Terrapins have varied coloration from black to spotted patterns on the soft tissue and dark or light-colored scutes with strong concentric layers on the carapace. The hind margin of the carapace curls up instead of flaring. Hind legs are large and toes have extensive webs. These turtles are strong, fast swimmers that feed on a variety of mollusks, crustaceans and other invertebrates. In South Carolina, salt marsh periwinkles (Littoraria irrorata) and blue crabs (Callinectes sapidus) are among the terrapin’s primary food sources (Tucker et al. 1995; Levesque 2000). Terrapins are sexually dimorphic. Females are much larger than males and reach 15 to 18 cm (6 to7 inches) in length; males reach 10 to 13 cm (4 to 5 inches) in length. Adult females also have enlarged heads. Terrapins hibernate in the mud during winter and mate in the spring. Eggs are laid May through early August and clutches have 5 to 12 eggs (Pritchard 1979). The number of clutches laid per female in South Carolina is undocumented; however two clutches may be common (David Owens, College of Charleston, pers. -

Common Musk Turtle
Common Musk Turtle Common Musk Turtle [Stinkpot] - Pl. 1 (Sternotherus odoratus) Identification: 2" - 5 3/8". The Common Musk Turtle has an olive-brown to black carapace, sometimes marked with dark spots or streaks. The carapace is smooth and domed, and may have green algae growing on its surface. The plastron is yellow to brown. Two key identifying features on the relatively small plastron are: (1) a single hinge, and (2) squarish pectoral scutes (just in front of the hinge). Other key features are two light stripes on the head (these may be hidden by dark pigment), and barbels (small fleshy projections) on the chin and throat. Where to find them: The Common Musk Turtle can be found in still or slow-moving bodies of water, where it prefers to walk slowly along the bottom. It basks just at or below the surface, but can also be seen basking on fallen trees and branches overhanging the water. When to find them: Active April through October. Range: Entire state. Note: In New Jersey, the turtle most similar to this is the Eastern Mud Turtle, which lacks the stripes and the barbels, and has two hinges instead of one. Common Musk Turtle (Sternotherus odoratus) - text pg. 10 Key Features - Carapace: smooth & domed. - Plastron: small with single hinge. - Barbels on chin, two light stripes on head.
