Maryland is one of the smallest states and is often called “America in Miniature” because of its diverse landscape. For example, the state contains just about any natural feature except for the desert. This is due to the abundance of water in the state. Furthermore, its nickname also applies to the role Maryland played in the United State’s history. Moreover, this state is home to many ethnic groups of every origin. Maryland has turned out many notable lawyers, politicians, craftspeople, painters, health professionals, religious leaders, and writers. Little America also built the first railroad, dental school, and umbrella factory, and inventors from the state invented refrigerators, the gas light, and the linotype machine. It’s hard to think that all this came from such a small state, but just how big is Maryland?

The Capital of Maryland

Annapolis is the State capital of Little America. Located on the Western Shore of the state in Anne Arundel County, this city is only 25 miles from Baltimore and 30 miles from Washington, DC. The state was founded in 1634. However, the first seat of Maryland’s colonial government was St. Mary’s City in southern Maryland. But, as the population in the state grew, St. Mary’s City was too far for most of the colony’s residents. As a result, in 1694, Anne Arundel Town, midway up the Chesapeake Bay, was designated as the new State Capital by the General Assembly, and the government moved its records and operations there in March 1694.

Wildlife in Maryland

Maryland, while small, contains an estimated 93 species and subspecies of reptiles and amphibians, 90 species of mammals, several hundred species of marine and freshwater fishes, and 400 species of birds. Furthermore, there are an undetermined number of insect and invertebrate species in the state, like spiders, crustaceans, and mollusks. Some of these animals include:

Coyote

It’s no secret that coyotes are adaptable and can survive in habitats like open fields, forests, greenways surrounding suburban neighborhoods, and tidal wetlands. In Maryland, they utilize spaces while remaining out of sight. Coyotes are one of the few animals that can thrive in urban settings.

Black Bear

Maryland’s black bears are primarily found in Washington, Allegany, Garrett, and Fredrick counties. However, their largest populations occur in Allegany and Garrett counties, but numbers overall are rising in the state. Black bear sightings are most common in the spring throughout Maryland.

Eastern Copperhead

The eastern copperhead is fairly common in forested rock outcrops of central and western Maryland but extremely rare on coastal plains. Unfortunately, they are so well camouflaged that it’s hard to see them even when looking straight at them. And they are venomous, so if you do step on one and get bitten, seek medical attention immediately.

Timber Rattlesnake

These rattlesnakes are shy and generally avoid areas populated by humans. They are nocturnal during the summer to avoid the heat and diurnal during the spring and fall. However, they are most active after hibernation during spring. Timber rattlesnakes are highly venomous and will readily attack if provoked. Their bites are excruciatingly painful and can cause significant damage. So, seek medical attention immediately.
