The wood turtle survey and analysis design we developed and tested was effective for estimating abundance of wood turtle populations in northeastern Minnesota, and we encourage its use as a template for wood turtle monitoring programs in the Upper Midwest. It occurs north into Ontario, east to Nova Scotia, and south from northern Iowa to northern Virginia. The wood turtle is a species of high regional concern (conservation concern and high regional ... considerations (NEPARC 2010, Therres 1999). Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species. The adult female wood turtle (above) is from a long-term study population in Ontario, Canada. population of 35 wood turtles, 32 (91.4%) were adults distributed in a 1:1 sex ratio [16 (45.7%) females and 16 (45.7%) males], and 3 (8.6%) were juveniles. Other scientific names are Clemmys insculpta and Testudo insculpta. 3. These turtles hibernate in the winter between approximately October and March, and may estivate during the warmest days in the summer. 2013). Wisconsin Department of Natural Resources. Wood turtles are habitat generalists, using a wide variety of forested habitats that are in close proximity to water (Ernst and Lovich 2009). Known hatchling emergence dates in Virginia are from June to August. Each scute (scale-like section) has pyramidal concentric ridges (growth lines), giving the carapace a sculptured appearance. Fortunately, law enforcement has gotten serious about prosecuting such poachers. HETEROZYGOSITY OF A WOOD TURTLE POPULATION IN CENTRAL NY .

This is a medium-sized turtle, up to 9 inches in length, with a keeled, sculptured carapace. The Canadian population of the Wood Turtle is estimated to be between 6000 and 12 000 adults. Because of its dependence on forested riverine systems and well-drained soils, the wood turtle was probably never uniformly distributed in the Upper Great Lakes Region, but was locally abundant in areas with optimal habitat. Wood turtles are currently Because of this, the wood turtle … The decline of wood turtle populations in Pennsylvania and a dozen other northeastern states led to a 2020-21 federal grant of nearly $1 million for habitat work, battling against the illegal pet trade in the species and other conservation actions. Canadian Population: 6,000 - 12,000 Wood Turtles forage primarily in terrestrial habitats for berries, mushrooms, and a wide range of invertebrates. Canon EOS Rebel It has a discontinuous range from Nova Scotia west through New Brunswick, Quebec, Ontario and Minnesota and south to Virginia and Maryland. Young wood turtle hatchlings are normally as big as 1 to 1.5 inches in carapace length with brown or pale grey plastrons. The Wood turtle gets it's name from the appearance of the carapace (upper shell), as it looks like wood grains. Many watersheds may contain functionally extinct populations as a result of habitat destruction, water quality degradation, road mortality, nest predation, illegal collection and forestation of open nesting and basking habitat. However, during the active period of summer, it may spend considerable time away from water foraging for food, even becoming mostly terrestrial for periods of time 2,3.. She is from an exceptionally light-colored population — the shell matches the yellow algae found on rocks in their stream habitat. Wood Turtles are listed as vulnerable in Nova Scotia. We estimated site‐level abundances and compared survey designs using a multinomial N‐mixture model that included a removal sampling observation process. The wood turtle is a cryptic semi-aquatic species that is declining across its range and, like so many chelonian species, is in-need of a rapid and effective method for monitoring distribution and abundance. The wood turtle is found in most New England states, Nova Scotia, west to Michigan, northern Indiana and Minnesota, and south to Virginia. Bouts consisted of tramping rhythmically several times with one front foot and then the other at a rate of one stomp per second, causing the anterior body to rock side to side. 83 0 obj <> endobj Wood turtles are mostly diurnal, and often enter the water or seek shelter on land under grass, leaves, or brush at night (Ernst and Lovich 2009). Special management practices for wood turtles should address their … Kaufmann (1986) described the foraging behavior of "stomping" for earthworms and other invertebrate prey in a population of wood turtles in Pennsylvania. 2016. Wood Turtles are now considered as endangered species because there was a time that people capture them and treat them as food. The wood turtle (Glyptemys insculpta) is a species of conservation concern for federal and state agencies because of population declines across the species’ range. Mean abundance estimates were similar with ≥6 replications. Active recovery efforts are taking place, though threats continue to increase in both number and severity. Sex ratio and mean carapace length did not differ based on whether we surveyed 2 or 4 transects, and percentage of individuals by size class was nearly identical between the sampling designs. Each season a new annulus, or ridge, is formed, giving each scute (a scale-like horny layer) a distinctive pyramid-shaped appearance. There is concern about the Wood Turtle population of the province. Distribution and Population. The total area of known and potential wood turtle habitat protected in occupied watersheds ranged from 0 to 2,193 ha (mean = 518 ha).

The wood turtle (Glyptemys insculpta) also known as wood carved turtle belongs to the Emydidae family, which has 85 species.It is an aquatic turtle that lives on land more than in water. According to experts, wood turtles produce a whistling sound whenever they are courting.

Current records of wood turtle occurrence do little to help us understand how well or poorly a population is doing at a particular site. Also, these turtles are commonly collected illegally for the international pet trade. The wood turtle (Glyptemys insculpta) is a species of conservation concern for federal and state agencies because of population declines across the species’ range. The population ecology of this species in the southern edge of the range of this species is unknown. The Wood Turtle (Glyptemys insculpta) is a species of special concern in Pennsylvania, largely due to habitat loss, alteration, and fragmentation, poaching, and road mortality. It was listed as a Threatened in Schedule 1 of the Species at Risk Act (SARA) in 2010. Wood Turtle Planning Team composed of biologists with expertise to guide Wood Turtle development of the conservation plan. Wood turtles prefer slow moving streams and rivers for winter hibernation and spring and fall activities. Despite many sightings and seemingly large and diverse distribution, Wood turtle numbers are in decline. Scientifically termed Glyptemys insculpta, the wood turtle is also known as ‘old red leg’, a name acquired due to its orange/brick-red colored legs. Many states across the species range have reported declines, population structures with a disproportionate number of adults, or local extirpations (Ross et al. Led by Steve Enders and Andy Weber, The Wood Turtle Population project is a field-based research project conducted in collaboration with the Turtle Survival Alliance – North American Freshwater Turtle Research Group. 104 0 obj <>/Filter/FlateDecode/ID[<1BBA21CA730B451A8A78FD36FBAEC48C>]/Index[83 40]/Info 82 0 R/Length 98/Prev 765807/Root 84 0 R/Size 123/Type/XRef/W[1 2 1]>>stream Between 2009 and 2011, the NEWTWG identified a Status Assessment and regional Conservation Strategy as priority action items.
