The biggest problem is the grey squirrel, introduced from North America in the late 19th and early 20th century. Populations of eastern gray squirrels, fox squirrels, California ground squirrels and wild turkeys are expanding and may compete with, and negatively impact, western gray squirrel populations. Differences in eastern gray squirrel (Sciurus carolinensis) abundance were studied in five types of habitat in Springfield, MA, from July 1974 to December 1976.These data were compared with selected habitat variables to determine whether differences in those variables could quantify differences in squirrel abundance.
