However, behavior and physiological state strongly mediated this trend with snakes selecting warmer and more heavily disturbed sites when thermoregulation was a priority (e.g., gestation, ecdysis) and more moderate temperatures when foraging. We also evaluated forest structure and composition metrics commonly used in the silvicultural decision support system SILVAH, but most (tree diversity, oak dominance, total DBH, total basal area) were not good predictors of site use. However, snakes were more likely to use sites with relatively low tree density, along upper slopes and on ridges making both relative tree density and ELTP (Ecological Land Type Phase) good predictors of snake site use. We were also able to model rattlesnake ingress and egress at our site using meteorological variables, but day of year was the most important variable in the model with temperature also having a modest effect on fall and spring phenology. Though the beginning of the state’s fall burning season (October 15th) overlapped aboveground activity, on average, for about half of our telemetered snakes, there was relatively little aboveground snake activity prior to the end of the spring burning season (April 15th). Additionally, we used our model to retrospectively predict the risk of exposure for rattlesnakes in southern Ohio during 12 previous prescribed burns and found that risk of exposure, on average, was low (

Download The Timber Rattlesnake Book in PDF, ePub and Kindle
The Timber Rattlesnake: Life History, Distribution, Status, and Conservation Action Plan was developed by a team of more than seventy-five concerned rattlesnake biologists from federal and state agencies, universities, and private institutions, as well as environmental consultants and private citizens. The 472-page book is divided into two parts and contains more than 300 images from 90 photographers and more than 40 maps. Part I of the document presents an overview of the life history, genetics, ecology, distribution, status, and threats to the continued existence of Timber Rattlesnakes from a range-wide perspective along with recommendations for conducting population assessments. Part II of the document presents the legal status, distribution, population status, habitat needs, active period, threats, and management actions for Timber Rattlesnakes on a state-by-state (or province by-province) basis. The information provided in this plan can serve as a reference for landowners, land managers, and government agencies at all levels to enable them to develop science-based management and conservation plans for Timber Rattlesnake populations and protect habitats for which they have responsibility. The guidance provided in this plan will also be of value to environmental consultants as they develop recommendations for developers, and to researchers who endeavor to fill in gaps in our knowledge concerning the species' distribution and ecology.

Download Timber Rattlesnakes in Vermont & New York Book in PDF, ePub and Kindle
Today, small populations of timber rattlesnakes (Crotalus horridus) quietly inhabit parts of Rutland County in Vermont, and Warren, Washington, and Essex counties in New York. Because the species is endangered, the exact locations of established dens in this area are a closely guarded secret. Insider, naturalist, and author Jon Furman has devoted years to the study of the snake's past and present range, its habitat and biology, the period in Vermont and upstate New York history during which timber rattlesnakes were ruthlessly hunted for a bounty, and the outlook for this severely threatened species in both states. Soundly anchored in the latest scientific data, Furman proffers an accessible and engaging account of contemporary fieldwork and first-person interviews with herpetologists and old-time bounty hunters. For expert and lay readers interested in snakes and reptiles, northeastern fauna and natural history, conservation, and endangered species, this volume clearly explicates the timber rattlesnake's biology as well as what happens and what to do when one bites. It also explores the troubling decline of the northeastern population caused by bounty hunting between the 1890s and the early 1970s, other past and present threats to the species' survival, and what measures are being taken-and additional ones that must be taken-to ensure that timber rattlesnakes survive and thrive in the northeast. Historical and contemporary illustrations bring these reptiles and their world to life. Timber Rattlesnakes in Vermont & New York shines a new light on a maligned and misunderstood species.

The ominous rattle of the timber rattlesnake is a chilling shorthand for imminent danger, and a reminder of the countless ways that nature can suddenly snuff us out. Though they're found in thirty-one states, and near many major cities, in contemporary America timber rattlesnakes are creatures mostly of imagination and innate fear. Levin takes us from labs where the secrets of the snake's evolutionary history are being unlocked to far-flung habitats to explore the painful struggles involved in protecting and preserving its natural world.

Download Factors Affecting Movement of Radio-tracked Timber Rattlesnakes (Crotalus Horridus) in Southern Ohio Book in PDF, ePub and Kindle
Males moved longer distances than females, and peak movement for all snakes occurred in July and August when temperatures were highest. This coincides with the mating season. It is possible that the timing of the mating season is influenced by temperature as peak temperatures will allow males to reach activity levels needed for extensive movement in search of females.

Download Timber Rattlesnakes' (Crotalus Horridus) Use of Man-made Rocky Features Constructed in Roadway Right-of-ways Book in PDF, ePub and Kindle
We investigated Timber Rattlesnakes (Crotalus horridus) use of the highway right-of-way (ROW) of the Nelsonville Bypass on Ohio state Route 33. We employed radio telemetry, camera trapping, operative thermal models and small mammal trapping to determine snake use of the ROW and determine why snakes might be attracted to this habitat. We discovered that the ROW is used predominantly by gravid females as gestation sites but by all snakes during times of the year when environmental conditions are cooler. Gravid females use the ROW because they can attain their preferred body temperature, which is higher than males and non-gravid females, for longer periods throughout the day and at reduced risk to predation. Other size and sex classes likely prefer more wooded habitat because food resources are more abundant and thus more appropriate for the sit and wait predation tactic of rattlesnakes. We detected three additional rattlesnakes previously unknown to us with camera traps, two of which were caught in the manmade, riprap erosion control structure in an area where no snake fence exists. Our management recommendations are 1) do not revegetate the ROW of the bypass, 2) relocated and extend the snake fencing to be more effective and include areas where additional snakes have been discovered and 3) establish a research program to evaluate the effectiveness of the proposed fencing changes and how it impacts snake use of the ROW.

Wildlife and Recreationists defines and clarifies the issues surrounding the conflict between outdoor recreation and the health and well-being of wildlife and ecosystems. Contributors to the volume consider both direct and indirect effects of widlife-recreationist interactions, including: wildlife responses to disturbance, and the origins of these responses how specific recreational activities affect diverse types of wildlife the human dimensions of managing recreationists the economic importance of outdoor recreation how wildlife and recreationists might be able to coexist The book is a useful synthesis of what is known concerning wildlife and recreation. More important, it addresses both research needs and management options to minimize conflicts.
