This is a list of mammals of Maryland, those mammals native to or immediately off the coast of the U.S. state of Maryland. [1]
Maryland does not have a designated state mammal, but does designate the calico cat as its state cat, the Chesapeake Bay Retriever as its state dog, and the Thoroughbred as its state horse. Seven species of mammals in Maryland have been extirpated: the eastern wolf, elk, American bison, cougar, snowshoe hare, American marten and eastern harvest mouse. Additionally, some have been introduced. The coypu, an invasive species, has since been extirpated through culling efforts. [2]

A lynx is any of the four extant species within the medium-sized wild cat genus Lynx. The name originated in Middle English via Latin from the Greek word lynx, derived from the Indo-European root *leuk-, in reference to the luminescence of its reflective eyes.
The groundhog, also known as the woodchuck, is a rodent of the family Sciuridae, belonging to the group of large ground squirrels known as marmots. A lowland creature of North America, it is found through much of the Eastern United States, across Canada and into Alaska. It was first scientifically described by Carl Linnaeus in 1758.
St. Mary's College of Maryland (SMCM) is a public liberal arts college in St. Mary's City, Maryland. Established in 1840, St. Mary's College is an honors college that claims to "offer an experience similar to that of an elite liberal arts college". With about 1,600 enrolled students, the institution offers bachelor's degrees in 21 disciplines, as well as a master's program and certification programs.
The eastern gray squirrel, 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. Widely introduced to certain places around the world, the eastern gray squirrel in Europe, in particular, is regarded as an invasive species.
James Lowell Stoltzfus is a former Republican state senator, having represented Maryland's 38th Legislative District. He was also a member of the Maryland House of Delegates for District 38.
The North American cougar is a cougar subspecies in North America. It is the biggest cat in North America. It was once common in eastern North America and is still prevalent in the western half of the continent. This subspecies includes populations in western Canada, the western United States, Florida, Mexico and Central America, and possibly South America northwest of the Andes Mountains. It thus includes the extirpated eastern cougar and extant Florida panther populations.
The eastern cougar or eastern puma is a subspecies designation proposed in 1946 for cougar populations in eastern North America. The subspecies as described in 1946 was declared extinct by the U.S. Fish and Wildlife Service in 2011. However, the 1946 taxonomy is now in question. The Canadian Wildlife Service has taken no position on the taxonomy. Cougars are currently common in western North America and may be expanding their range. Individuals are occasionally seen as vagrants in eastern North America.
The richness and variety of the wildlife of Ethiopia is dictated by the great diversity of terrain with wide variations in climate, soils, natural vegetation and settlement patterns. Ethiopia contains a vast highland complex of mountains and dissected plateaus divided by the Great Rift Valley, which runs generally southwest to northeast and is surrounded by lowlands, steppes, or semi-desert.
The West Virginia State Wildlife Center is a zoological park in French Creek, West Virginia. Operated by the West Virginia Division of Natural Resources, the Wildlife Center displays many of West Virginia's wildlife, including both native and introduced species. A few of the animals at the Wildlife Center were once found naturally in West Virginia, but were extirpated by the early 1900s.
The U.S. state of Wyoming faces a broad array of environmental issues stemming from natural resource extraction, species extirpation, non-native species introduction, and pollution. Wildlife species that have been affected by these issues include:
The fauna of the state of Oregon includes a wide array of species.
