Silver Springs Road, Kingman, Arizona 86401, USA.Phone: 928-692-6501. Email: [email protected] The Willow Creek Riparian Preserve (Preserve) is a privately owned 130-acre site located 30 miles east of Kingman, Arizona. The Preserve was formally established in 2007 with the purchase of 10-acres and an agreement with the eastern adjoining private landowner to add an additional 120-acres. The Preserve location was unfenced and wholly accessible by livestock, off-road vehicle use, and hunting. In October of 2008 the Preserve was fenced with volunteer efforts from the local Rotary Club and Boy Scout Troop 66. Additional financial assistance came through a large discount in the cost of fencing materials from Kingman Ace Hardware. A total of 0.5-linear mile of new wildlife friendly fencing (barbless top wire and 18-inches above-ground bottom wire) was installed along the south and west sides and connected to existing Arizona State Lands cattle allotment fencing. Baseline and on-going studies and data collection have occurred since 2004. These have included small mammal live trapping; chiropteran surveys with the use of Anabat; migratory, breeding, and winter avian surveys; amphibian and reptile surveys; deployment of game cameras; animal track and sign identification and movement patterns; vegetation and plant surveys; and a wetland delineation. -

Loggerhead Sea Turtle
Loggerhead Sea Turtle Description: The Loggerhead Sea Turtle is named for its large head and blunt jaw. This huge sea turtle can grow to 800 pounds (though the average turtle is about 200 pounds) and three and a half feet in length. It is the largest hard-shelled turtle in the world. The carapace (shell) and flippers are reddish brown and the plastron (lower shell) is yellowish. The carapace has five lateral scutes and five central scutes. Scutes are hexagonal sections of the carapace. Underparts are white or whitish. These incredible turtles have powerful flippers that can propel them through the water at speeds of up to 16 miles per hour. The Loggerhead Sea Turtle has a life span of up to 50 years in the wild. Habitat/Range: The seafaring Loggerhead Sea Turtle is found throughout the world's tropical oceans. They are also found in temperate waters in search of food and in migration. Breeding populations exist in many locales including the Atlantic coast of the United States (from North Carolina to Florida), numerous Caribbean islands, Central America, the Mediterranean Sea, and Africa. Diet: Loggerhead Sea Turtles consume fish, crustaceans, mollusks, crabs, and jellyfish, They use their powerful jaws to crush prey. These turtles often ingest stray plastic bags which are mistaken for jellyfish and which cause potentially fatal complications. Nesting: The Female Loggerhead Sea Turtle normally lays her eggs on the same beach in which she was born. It may take up to 30 years before these turtles reach reproductive age. In June or July, females will emerge from the ocean and dig a hole in the sand. -

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. -

Snyder Dr. C. Richard Tracy/Dissertation Advisor May 2014 THE GRADUATE SCHOOL We recommend that the dissertation prepared under our supervision by SARAH J.

Richard Tracy, Ph.D., Advisor Kenneth Nussear, Ph.D., Committee Member Peter Weisberg, Ph.D., Committee Member Lynn Zimmerman, Ph.D., Committee Member Lesley DeFalco, Ph.D., Graduate School Representative David W. Zeh, Ph. D., Dean, Graduate School May, 2014 i ABSTRACT Among the many threats facing the desert tortoise (Gopherus agassizii) is the destruction and alteration of habitat. In recent years, wildfires have burned extensive portions of tortoise habitat in the Mojave Desert, leaving burned landscapes that are virtually devoid of living vegetation. Here, we investigated the effects of fire on the thermal ecology of the desert tortoise by quantifying the thermal quality of above- and below-ground habitat, determining which shrub species are most thermally valuable for tortoises including which shrub species are used by tortoises most frequently, and comparing the body temperature of tortoises in burned and unburned habitat. To address these questions we placed operative temperature models in microhabitats that received filtered radiation to test the validity of assuming that the interaction between radiation and radiation-absorbing properties of the model can result in a single, mean radiant absorptance regardless of whether the incident solar radiation is direct unfiltered or filtered by plant canopies, using the desert tortoise as a case study. -

Throughout its restricted range, Dermatemys has been intensely harvested for its meat and eggs and sold in local markets. -

Allison Desert Tortoise Recovery Office, US Fish and Wildlife Service, 1340 Financial Blvd. #234, Reno, Nevada 89502. Email: [email protected] The U.S. Fish and Wildlife Service has standards for determining whether species should have federal protection. It also has standards for describing a viable species, couched in terms of representation, redundancy, and resilience. These characteristics were used in the 1994 Recovery Plan to design and evaluate the size and location of proposed critical habitat units for the Mojave desert tortoise. Regarding long-term representation and resilience, critical habitat units were designed to sustain a population of at least 5000 adult tortoises. In situations where the critical habitat unit was smaller than the threshold of 500 sqmi or if the number of tortoises was found to be fewer than 5000, it was expected that land management would result in connectivity to larger populations outside the critical habitat unit and to other critical habitat units. At the time the original recovery plan was developed, there were no estimates of the number of tortoises in any particular critical habitat unit and little information about how tortoise populations were connected for short-term viability. In the meantime, we are able to use population estimates to evaluate connectivity management needs for critical habitat units and to describe what long- and short-term connectivity entails for tortoise populations.
