Background
Mink can be found from the North Slope of Alaska to the southern tip of Florida (except for Arizona and parts of California and the Southwest, where conditions are too dry1). This wide distribution illustrates that mink are adapted to a wide range of climatic, vegetative, and geological conditions.
Climate Impacts
The mink’s wide geographic range suggests that it should be relatively adaptable to future climate change in the state of Massachusetts over the next century. However, mink are a semiaquatic species associated with water, with much of their diet composed of fish, amphibians, crayfish, muskrats, and waterfowl2,3,4,5. The abundance of mink is thus directly related to the availability of wetlands and water6,7. Climate change is predicted to result in increased short-term drought conditions, reduced summer stream flows, and longer duration of low summer flows in the Northeast, all of which have the potential to reduce the amount of aquatic habitat8. A reduction in the amount of aquatic habitat in Massachusetts could also reduce mink numbers.

Although this species was identified as not vulnerable to climate change, the following factors increase vulnerability:
- Has already experienced slight variations in annual precipitation (over the last 50 years)
The factors below decrease this species' vulnerability to climate change:
- Ability to move across the landscape and/or disperse relatively long distances
- Not restricted by the need for specialized habitat
