Taxonomy
There are differences of opinion as to the
Etymology
Both the specific name, blandingii, and the common name, Blanding's turtle, are in honor of American naturalist Dr. William Blanding (1773–1857).[11]
Description

The Blanding's turtle is a medium-sized turtle with an average straight
Reproduction
Blanding's turtles take 14–20 years to reach sexual maturity. Mating probably occurs in April and early May with nesting beginning in early June and lasting throughout the month.[12] The clutch size varies from region to region. In New York, the clutch size ranges from five to twelve eggs, with an average of eight.
Behavior and life span
Blanding's turtles
The Blanding's turtle is a timid turtle and may plunge into water and remain on the bottom for hours when alarmed. If away from water, the turtle will withdraw into its shell. It is very gentle and rarely attempts to bite. It is very agile and a good swimmer.
Distribution and habitat
The geographic range of E. blandingii centres on the Great Lakes, and extends from central Nebraska and Minnesota (where it twice failed to become the state reptile)[13] eastward through southern Ontario and the south shore of Lake Erie as far east as northern New York. In Nebraska, this turtle is uncommon in the eastern portion of the state, but common to abundant in the Sand Hills region lakes, ponds, and streams. There are also isolated populations in southeastern New York (Dutchess County), New England, and Nova Scotia.[14]
Its general habitat is
Conservation status
The primary threat to the Blanding's turtle is
This species can also be adversely affected by prescribed burns. During fall and late spring hatchlings move overland and it is recommended that prescribed burns should be avoided during these times.[15]
The U.S. states in which it is considered endangered are Indiana,[16] Illinois, Missouri,[17] Maine, New Hampshire, Massachusetts, and South Dakota.[18] It is considered threatened in New York and Iowa.[19][20] In Michigan, Blanding's turtle is also fully protected as a special concern species;[21] making it unlawful to kill, take, trap, possess, buy, or sell.[22] In Lake County, Illinois, a long-term species recovery program has been underway since 2009.[23]
In Canada, the Great Lakes–St. Lawrence River population in Ontario and Quebec is federally threatened[24] and the Nova Scotia population is endangered.[25] Conservation and recovery efforts in Nova Scotia have been in place for two decades and rely on habitat and life history monitoring based on the work of researchers and volunteers. Habitat protection has proven crucial. The population in Kejimkujik has been placed under the highest level of protection; the McGowan Lake population was initially protected by Bowater but has since been taken over by the Province. In Pleasant River, Nova Scotia Nature Trust protects four separate segments of critical habitat.[26]
