Assesses the conservation status of Clemmys insculpta, the wood turtle, which ranges discontinuously in north-eastern North America and is confined to specific habitats associated with streams. Information is included on the turtle's geographic distribution in Canada and the United States, population size and trends, protection status, habitat, general biology, factors limiting the turtle population size and distribution, and the special significance of the species. Concludes with brief discussion of the current consensus regarding the status of the species and a recommendation for designation of the species as vulnerable.

I investigated the habitat selection of wood turtles (Glyptemys insculpta) in a landscape within active agriculture and assessed the risk of agricultural practices. I tracked 23 wood turtles and recorded their habitat use versus availability on a 3rd and 4th order scale. I found that wood turtles preferred fields over the forest and that hay fields are likely an attractant to wood turtles due to high food availability and low canopy cover. Wood turtles used the hayfields during the hay harvest season, and stayed close to field edges. I monitored the movement response of wood turtles as they were approached by agricultural machinery and found that most turtles could not successfully escape the mower. My study shows that agriculture poses a high risk to wood turtles in an agricultural landscape and management strategies are necessary to prevent populations from extirpation.

Worldwide turtle and tortoise populations are declining, including the semi-aquatic wood turtle (Glyptemys insculpta) of eastern North America. With a limited survey season, a more efficient method of detection was needed to monitor this cryptic species. DNA barcoding with environmental DNA (eDNA) has been shown to be an effective method of monitoring cryptic, rare, and threatened species. Water samples were collected in October 2017 and 2018 from an upstream and downstream site on fourteen rivers in New Brunswick, Canada. In our eDNA lab, the samples were filtered, extracted and, with the use of species-specific primers and probe, amplified using quantitative polymerase chain reaction (qPCR). With the use of qPCR, wood turtle eDNA was detected in five of six rivers known to inhabit the species. This method is a promising tool that can be used for the conservation and monitoring of G. insculpta.

The wood turtle, Glyptemys insculpta, is listed as threatened federally in Canada and provincially in Nova Scotia (NS) and New Brunswick (NB). Historic surveying for G. insculpta in these provinces has been arbitrary and geographic knowledge gaps persist. To address these gaps, this research developed species distribution models for NS and NB using Maxent software, G. insculpta occurrence data, and environmental data relevant to the species' ecology. Resulting important model variables included 'Elevation', 'Distance to Alder', and 'Watercourse Density'. The model outputs were used to guide field surveys, which recorded G. insculpta occurrences at twelve new sites. In NS, the model output's prediction of G. insculpta distribution overlapped with 80.4% of identified core habitat, but only 4.6% of this predicted distribution was within protected areas. The findings will contribute to conservation of this at-risk species by predicting its distribution, and in doing so, inform future survey efforts and conservation decisions.
