The eastern gray squirrel (Sciurus carolinensis), also known, particularly outside of North America, as simply the grey squirrel, is a tree squirrel in the genus Sciurus. It is native to eastern North America, where it is the most prodigious and ecologically essential natural forest regenerator.
These eastern grey squirrels are considered an invasive species in Europe because of their presence contributing to the displacement of the red squirrels. The invasion of the grey squirrel in the United Kingdom can be classified as a Disease Mediated Invasion (DMI). [ 6 ]
This is a list of invasive species in North America.A species is regarded as invasive if it has been introduced by human action to a location, area, or region where it did not previously occur naturally (i.e., is not a native species), becomes capable of establishing a breeding population in the new location without further intervention by humans, and becomes a pest in the new location ...

The species is the largest tree squirrel in the state. It’s being threatened by climate change, habitat loss and frequent disease outbreaks. Gray squirrel may become endangered species in WA.
An invasive species will be one that thrives in its new environment and negatively influences the ecology and biodiversity of that ecosystem. Negative effects can also affect humans, by compromising health (e.g. vectors of diseases) or socioeconomic systems (e.g. damages to agriculture or forestry).
