Book Description
The Blanding's Turtle (Emydoidea blandingii) has received threatened status in the State of Ohio in 2010. The goal of this study is to provide information that can be used in conservation management to locate suitable habitat for conservation of the species as well as potential repatriation or trans location sites. Wetland Inventory and Land Use/Land Cover maps were combined with aerial photography to evaluate regions located in Ohio's Lake Erie Drainage Basin that would meet the essential requirements of the turtles life history by quantitative methods used in Geographic Information Systems (GIS) and Remote Sensing programs. This study identified suitable wetlands and vernal pools, lakes and ponds, and other areas with minimum canopy for nesting and movement. Throughout the region, the highest concentration of available habitat is found in Erie, Lucas, and Ottawa counties of the Blanding's turtle's historical range. This approach to creating Habitat Niche Models was validated by close correlation between the counties identified as having remaining appropriate habitat and the counties from the historical populations in which Blanding's turtles still remain. The potential exists to restore these areas through various means: restoring wetlands, protecting areas near agriculture that are more suitable for nesting, constructing small tunnels under roads and fences, and installing road warning signs to allow for safer migration. With protection and restoration of the habitat, the species may still have a chance to recover and become a stable population without the need for intense management.

Book Description
As habitat loss and fragmentation are major causes of decline in animal species, studying habitat requirements in these species is a key component of their recovery. I investigated the relationship between landscape composition and habitat use of Blanding's turtles, Emydoidea blandingii, a freshwater turtle threatened by habitat loss and road mortality on most of its Canadian range. In 2010, I conducted a radio-telemetry survey of 44 Blanding's turtles in southern Québec, Canada, and modelled their home range size from land cover proportions measured at many spatial scales. I also used data from a visual survey conducted in 2008 and 2009 to model wetland occupancy of the species at the landscape scale. Home range size of the Blanding's turtle was significantly correlated to landscape composition, and the proportions of agriculture, open water and anthropogenic lands had the strongest relationships with home range size. However, those relationships were weak and the models were unable to predict home range size accurately. At the landscape scale, land cover and road density poorly predicted probability of occurrence, and Blanding's turtles occupied wetlands in both disturbed and natural sites. Management of the species should focus on protecting sites of occurrence with high wetland density, low road density, and sufficient suitable habitat to cover their seasonal movement patterns.

Book Description
Reports a study conducted to: document the movement patterns of young Blandings turtles (Emydoidea blandingii); and identify areas used by young turtles as rearing grounds and hibernation sites. The study area was located in a park in south-western Nova Scotia. The turtles were hand-reared to an age when they could be fitted with radio transmitters and were then released at four sites, three located on small brooks and the fourth at a small pond. All release sites had boggy floodplain areas dominated by shrubs, grasses, and sphagnum moss. Tagged turtles were tracked daily for the first few days after release to determine whether they would move significantly after release. When determined they would not move significantly, they were positioned by telemetry every 3-7 days and recaptured every 3-14 days. Recaptured turtles were measured and examined to determine their condition. Results are presented and discussed related to turtle survival, movement, predation, behaviour, and habitat use.
