Venomous reptiles of North America. 2000. This species is  facing severe declines across its range due to habitat loss, overharvesting, and general persecution. Across much of their range C. horridus is one of the largest species, commonly reaching up to four feet in length. This allows the snake to feel for vibrations of potential prey items, typically rodents.

There exists a degree of sexual dimorphism in this species with males reaching greater lengths than females (Typically greater than 42 inches). from East Stroudsburg University of Pennsylvania where he conducted research on how human disturbance effects population size of timber rattlesnakes.

Wilcove D.S., Rothstein D., Dubow J., Phillips A. The average person is largely biased against rattlesnakes and hiking trails through habitat increase the likelihood of human interaction with the species, leading to eventual mortality. The works by Schaefer, 1969 also showed that color morph could be determined at birth and would only be reinforced with age. These fangs are attached to large venom glands by venom ducts. 1993. 65: 478–486. 1973.

Behavioral Responses to Roads and Vehicles. Lastly, this species has a facial pit on either side of the head between the nostril and the eye. & Burger J. State Geological and Natural History Survey of Connecticut, Hartford. That is, this species has large, retractable fangs that replace the maxillary teeth and fold against the maxillary bone. The timber rattlesnake's relatively long lifespan, low reproductive rate, infrequent reproductive events, and high juvenile mortality leads to a population dominated by older age classes with variable annual recruitment (Minnesota DNR 2009).

These events awarded prizes to participants in various categories such as largest snake and longest rattle. “If I had to bet everything on it, somebody caught it and turned it loose in the parking lot (of Walmart) or somewhere else in the city. While timber rattlesnakes in Vermont have died after contracting snake fungal disease, scientists don’t know yet the extent of the threat or whether it will cause the state-endangered populations to decline even further. Herpetological Review.

Studies in Pennsylvania have since shown this to be a myth.

Gloyd H.K. The chance of there being a population of timber rattlesnakes within 15 miles of Murray is exceedingly low.

& Ernst E.M. 2003. Reproduction, Growth, and Sexual Dimorphism in the Canebrake Rattlesnake (Crotalus horridus atricaudatus. The name comes from one of the former subspecies of C. horridus, the canebrake rattlesnake, C. h. atricaudatus, and presents with a cream background color with dark chevrons, typically with an orange stripe. The factors described by Wilcove et al., 1998 all contribute to the population changes in C. horridus. Given the concerns around Lyme disease, and deer ticks preferred host species—the white-footed mouse—snakes are more important to our health than we realize.”. Snake fungal disease, thought to be causing declines in timber rattlesnake populations in neighboring New Hampshire and Massachusetts, is now appearing in Vermont.

Likewise, members of the “canebrake” variety tend to overwinter in stumps and tree root systems for short periods of extreme cold. The posterior portion of the pit contains a membrane stretched across it. Ophidiomyces ophiodiicola dermatitis in eight free-ranging timber rattlesnakes (Crotalus horridus) from Massachusetts. obs.). Principal Adam Bunting sent an, Vt. timber rattlesnakes face fungal disease. He said the woman reported that she had noticed the snake while in transit.

This species is commonly found in forested habitat across its range. Quantifying Threats to Imperiled Species in the United States. 75: 255.

For instance, in Pennsylvania there is an open season, with permits, during the summer to take one adult male timber rattlesnake. “Infectious diseases such as snake fungal disease and white-nosed syndrome can pose a serious threat to wildlife all over the world,” Blodgett said.

The last type, type C, was described by the author as being one of the weakest venoms the author has explored with a low LD50 in a lab setting, lacking both the canebrake toxin as well as the peptides that make type B potent. & Wüster W. 2019.

Jim Andrews, who heads up the Vermont Reptile and Amphibian Atlas, also keeps close tabs on snake sightings among members of the public. There are many biotic and abiotic factors that contribute to a population’s numbers and that may cause declines including habitat destruction, overharvesting, pollution, and disease (Wilcove et al., 1998).

In the northern part of the range, black racers, Coluber constrictor, are commonly found near den and gestation sites, and are known to take young C. horridus.

This lends several benefits including group defense against predators as well as increasing the ability to thermoregulate. 1935: 175–178. Klemens M.W.

Reinert H.K. The chance of there being a population of timber rattlesnakes within 15 miles of Murray is exceedingly low.

Hewlett also said the timber rattlesnake is very beneficial to the ecosystem.

He also said that the chances of the timber rattler biting someone are low. Healthy timber rattlesnake populations typically exist in a metapopulation structure where several over‐wintering dens are used and snakes interact during the mating season in the summer habitat in‐ between.
