Which of the following mammals is NOT allowed to be taken year-round?

Tree squirrels are regulated by specific seasons and limits, as they are classified under game mammals. Unlike some other species such as coyotes and skunks, which may be taken year-round under certain circumstances due to their population status or perceived pest status, tree squirrels have designated hunting seasons that align with conservation efforts and population management. This allows for sustainable harvesting while protecting the species during critical times, such as breeding seasons or when populations are vulnerable.

The other mammals listed have fewer restrictions concerning their harvesting and can generally be pursued throughout the year, reflecting their population dynamics and regulations that address wildlife management objectives. This distinction is vital for maintaining ecological balance and promoting responsible hunting practices.
