Where appropriate, captured snakes were monitored using telemetry methods over their entire activity season to characterize summer habitat use, determine their home range size, and to locate critical winter den sites. Below we summarize the major findings of this species management project. Wetland surveys did not reveal any habitat on JB MDL for the federally threatened bog turtle. A total of 16 northern pine snakes and 6 corn snakes were captured or observed during visual surveys over 69 days between June 6 and November 1, 2018. A total of 25 northern pine snakes and 10 corn snakes were captured or observed during visual surveys over 87 days between May 1 and October 1, 2019. No timber rattlesnakes were detected during surveys on JB MDL in 2018-19. No threatened or endangered snake species were captured in 3 drift fence trap arrays in 2018. Six additional drift fence trap arrays were installed in 2019. That same year the 9 arrays captured 5 northern pine snakes and 1 eastern kingsnake, which was new to the study. The eastern kingsnake is listed as a species of special concern in New Jersey. Radio-telemetry was used to characterize summer habitat use, home range size, and winter den sites for 3 pine snakes and 2 corn snakes throughout their activity season in 2018. Those individual snakes were tracked again in 2019, although one male corn snake experienced transmitter failure and a male pine snake was lost to predation. Detailed results from this telemetry monitoring are located on pages 42-52. In 2019, an additional 7 pine snakes and 3 corn snakes were implanted with transmitters and tracked throughout the field season. One female pine snake was lost to predation. Detailed results from this telemetry monitoring are located on pages 53-70. A total of 9 northern pine snakes and 3 corn snakes are currently being tracked on JB MDL. Telemetry monitoring of these individuals will continue through August 2020. 2019 Important Habitats and Future Management of Northern Pine Snake, Corn Snake and Timber Rattlesnakes at Joint Base – McGuire, Dix, Lakehurst, New Jersey Prepared by: David W. Schneider, Robert T. Zappalorti, David Burkett and Ryan Fitzgerald Herpetological Associates, Inc., 405 Magnolia Road, Pemberton, New Jersey 08068 12/1/2019 Important Habitats and Future Management of Corn Snake, Pine Snakes and Timber Rattlesnakes at JB MDL INTRODUCTION Herpetological Associates, Inc. (hereafter HA) was retained by Texas A&M Natural Resources Institute as their sub-consultant to conduct intensive habitat evaluations to identify suitable areas for the northern pine snake (Pituophis melanoleucus - state-listed threatened), red corn snake (Pantherophis guttatus - state-listed endangered) and timber rattlesnake (Crotalus horridus - state-listed endangered), on an approximate 6,000-acre study area within the larger Joint Base, McGuire-Dix-Lakehurst (hereafter JB MDL). This joint base military complex is located in Ocean and Burlington Counties, New Jersey (Figures 1 and 2). The goal of HA’s investigation was to provide baseline information regarding the status of these state-listed species on JB MDL to the Department of Defense in preparation of an Integrated Natural Resources Management Plan (INRMP). The INRMP will be used as a guideline for possibly avoiding potential impacts from the development of new and improved training facilities, improvements of firing ranges, and other upgraded military training facilities. Some of these actions may infringe upon the important habitat of these state-listed snake species. The results presented in this report are the preliminary findings from visual random searching efforts, drift fence trapping surveys and radio-telemetry studies conducted between May 24 and November 1, 2018 and May 1 and November 1, 2019 on JB MDL. HA is an environmental consulting company that specializes in endangered, threatened, and rare (ETR) plant and wildlife species, with particular emphasis on herpetology. HA has 42-years of experience working with rare plants, birds, reptiles and amphibians and has studied them extensively in New Jersey, New York, Pennsylvania and Florida. The results of some of HA’s research has been published in scientific journals and are available at HerpetologicalAssociates.com. All survey methods used are proven methods, used by researchers in various parts of the country for wildlife sampling. HA’s survey methods for endangered and threatened wildlife have been used successfully in the past and have been accepted by the New Jersey Department of Environmental Protection (NJDEP), United States Fish and Wildlife Service (USFWS), and the New Jersey Pinelands Commission (NJPC). BACKGROUND INFORMATION After all contract negotiations were completed, a kick-off phone conference was held on May 23, 2018, with representatives from Texas A&M, the Army Corps of Engineers, JB MDL and key HA staff members. Roel Lopez of Texas A&M Natural Resource Institute (NRI) conducted an online Power Point presentation. The various topics presented and discussed were aspects of the project overview, general herpetological methods to be employed, HA’s study plan, the time-line of field work, and the project deliverables. The phone conference set the stage for the planning and methods to be employed during this investigation. In March 2019, because of the lack of suitable bog turtle habitat on JB MDL, the contract was amended to shift the funds allocated for bog turtle surveys to additional snake surveys. This would increase the trapping effort from 3 drift fences to 6 and double the radio-tracking effort from 6 snakes to 12. In addition, in April, 2019, a new contract was awarded to extend the study to August, 2020 and increase the trapping effort to 9 drift fences and the radio-tracking to 16 snakes.

Identification and documentation of any potential critical habitat such as hibernacula (winter dens) and nesting areas (pine snakes). An intensive search for gravid female pine snakes and/or their nesting areas. The mapping of all initial snake capture locations, nesting locations and hibernacula via GPS/GIS and the marking of all target snakes (pine, corn, timber rattlesnake) with micro-chip PIT Tags. The photo-documentation of all target species and critical habitat features via digital camera. The surgical implantation of 3 adult northern pine snakes and 3 adult corn snakes (preferably 1 - 2 miles apart from each other) with radio-transmitters and monitor them throughout the 2018 and 2019 active seasons. Although permission was requested by HA, the NJDEP does not allow the radio-tracking of endangered snakes to identify the impacts of development on such species. HA was granted permission to radio-track corn snakes on JB MDL because they were added to an existing conservation based survey HA is conducting on Pine Barrens corn snakes. Based on a request from John Joyce (he has a lot of information from previous pine snake surveys conducted at the Lakehurst section of JB MDL), no pine snakes were radio-tracked from the Lakehurst section of JB MDL.

  • Bull Snake Class: Reptilia
    Pituophis catenifer sayi Bull Snake Class: Reptilia. Order: Squamata. Family: Colubridae. Other names: Gopher Snake, Pine Snake Physical Description: Bull snakes are usually yellow in color, with brown, black or reddish colored blotching or saddle spots on the sides of the snake. There are dark spots placed between the blotches or saddle spots. Below this is a further row of smaller dark spots. The belly is light brown. Many variations in color have been found, including albinos and white variations. This snake has a small head and a large nose shield, which it uses to dig. They often exceed 6 feet in length, with specimens of up to 100 inches being recorded. Males are generally larger then females. The bull snake is a member of the family of harmless snakes, or Colubridae. This is the largest order of snakes, representing two-thirds of all known snake species. Members of this family are found on all continents except Antarctica, widespread from the Arctic Circle to the southern tips of South America and Africa. All but a handful of species are harmless snakes, not having venom or the ability to deliver toxic saliva through fangs. Most harmless snakes subdue their prey through constriction, striking and seizing small rodents, birds or amphibians and quickly wrapping their body around the prey causing suffocation. While other small species such as the common garter snake lack powers to constrict and feed on only small prey it can overpower. Diet in the Wild: Bull snakes eat small mammals, such as mice, rats, large bugs as well as ground nesting birds, lizards and the young of other snakes.

The Western Terrestrial Garter Snake has a black or dark gray back with a dull yellow stripe down the middle. The dark background color has tiny white spots, which can be hard to see. fun facts When handled or otherwise disturbed, Garter Snakes usually release a stinky- smelling musk. life cycle During the winter, Garter Snakes hibernate under rocks and rotting logs, and in rodent burrows. They select mates in the spring after they come out of hibernation. In July, seven to thirty young are born live. ecology Garter Snakes feed on many different animals, including fish, frogs, toads, salamanders, insects, and earthworms. They are excellent swimmers and are usually found close to some source of water. They are eaten by a variety of mammals, birds and other snakes. conservation Some people kill snakes because they are afraid that the snakes might hurt them. They do not realize that the snakes are even more afraid of humans than we are of them! Garter Snakes, like many snakes, play an important role in controlling populations of rodents. Rodents are a group of mammals that includes mice, pocket gophers, voles, ground squirrels and other species.

  • Garter Snake Article Marin IJ David Herlocker If You Spend Any Amount
    Garter Snake Article Marin IJ David Herlocker If you spend any amount of time on the trails of Marin County, chances are that you occasionally catch a glimpse of a snake. It is not uncommon to find a gopher snake sitting motionless in a fire road, or to see the last few inches of a sleek brown racer as it disappears into the trailside grass. If your travels take you near a lake, a stream, or any other freshwater habitat, chances are you will encounter one of the three species of garter snakes that live here. The coastal marshes of Point Reyes are where you will usually find the gaudy red and turquoise common garter snake (our showy subspecies is called the California red-sided garter snake). In coyote brush and meadows you can expect to see our version of the western terrestrial garter snake (which is called the coast garter snake), and along our perennial streams and lakeshores you are most likely to encounter an aquatic garter snake. All of these snakes are characterized by the presence of one or more pale stripes that run the length of their body. When you see a garter snake against a plain background, this pattern looks anything but camouflaged, but when found among grasses or floating stems at the edge of a pond, the color scheme allows the snake to blend in perfectly. The name “garter snake” comes from this color pattern’s resemblance to the old fashioned striped garters that were used to hold men’s sleeves in place. Many people mistakenly refer to them as ‘garden snakes”; although they may be found in gardens, there is actually no species called the garden snake.

  • Garter Snakes by Linda Novak
    Notable Natives Garter Snakes by Linda Novak Many people are, at the least, mildly apprehensive when they come across a snake, but the common garter snake Thamnophis sirtalis is a good creature to have around and is likely to be heading away from you when you see it. Garter snakes eat insects, bird eggs, small birds, fish, amphibians and (here’s the beneficial part) field mice and voles. They, in turn, serve as food for bull frogs, hawks, owls, foxes and other predators. Garter snake. Image courtesy of Wikipedia Commons. The most common snake in Illinois, the garter snake is dark brown or black with one to three yellow stripes running from head to tail. The Chicago type, T. s. semifasciatus, has some red on the body, and its side stripes become dashed lines How does one avoid the unfortunate lawnmower-snake near the head.

Given the current global amphibian decline, it is crucial to obtain accurate and current information regarding species distributions. Secretive amphibians such as plethodontid salamanders can be difficult to detect in many cases, especially in remote, high elevation areas. We used molecular phylogenetic analyses to identify three partially digested salamanders palped from the stomachs of three Common Garter Snakes (Thamnophis sirtalis) from the Klamath Mountains in northern California. Our results conclusively show that the salamanders were all individuals of Ensatina eschscholtzii oregonensis, revealing a substantial vertical range extension for this sub-species, and documenting the first terrestrial breeding salamander living in the sub-alpine zone of the Klamath Mountains.
