Editing Common snapping turtle (section)

==Conservation==
The species is currently classified as [[Least Concern]] by the [[IUCN]], but has declined sufficiently due to pressure from collection for the pet trade and habitat degradation that Canada and several U.S. states have enacted or are proposing stricter conservation measures.<ref name=iucn/> In Canada, it is listed as "Special Concern" in the [[Species at Risk Act]] in 2011 and is a target species for projects that include surveys, identification of major habitats, investigation and mitigation of threats, and education of the public including landowners. Involved bodies include governmental departments, universities, museums, and citizen science projects.<ref>{{cite book|author=Environment and Climate Change Canada|year=2016|title=Management Plan for the Snapping Turtle (Chelydra serpentina) in Canada [Proposed]|series=Species at Risk Act Management Plan Series|publisher=Ottawa, Environment and Climate Change Canada|location=Ottawa|url=https://www.registrelep-sararegistry.gc.ca/virtual_sara/files/plans/mp_snapping%20turtle_e_proposed.pdf}}</ref>

Although common snapping turtles are listed as a species of least concern, anthropogenic factors still may have major effects on populations. Decades of road mortality may cause severe population decline in common snapping turtle populations present in urbanized wetlands. A study in southwestern Ontario monitored a population near a busy roadway and found a loss of 764 individuals in only 17 years. The population decreased from 941 individuals in 1985 to 177 individuals in 2002. Road mortality may put common snapping turtle populations at risk of extirpation. Exclusion fencing could aid in decreasing population loss.<ref>{{Cite journal |last1=Piczak |first1=Morgan L. |last2=Markle |first2=Chantel E. |last3=Chow-Fraser |first3=Patricia |date=November 2019 |title=Decades of Road Mortality Cause Severe Decline in a Common Snapping Turtle (Chelydra serpentina) Population from an Urbanized Wetland |url=https://bioone.org/journals/chelonian-conservation-and-biology/volume-18/issue-2/CCB-1345.1/Decades-of-Road-Mortality-Cause-Severe-Decline-in-a-Common/10.2744/CCB-1345.1.full |journal=Chelonian Conservation and Biology |volume=18 |issue=2 |pages=231–240 |doi=10.2744/CCB-1345.1 |s2cid=209338553 |issn=1071-8443|url-access=subscription }}</ref>
