The forest is disjointed, and comprises land in the towns of Haddam, Chester, Deep River, Killingworth, Durham, Guilford, Madison, Clinton, Westbrook, Middletown and Middlefield.
The environment of the United States comprises diverse biotas, climates, and geologies. This diversity leads to a number of different distinct regions and geographies in which human communities live. This includes a rich variety of species of animals, fungi, plants and other organisms.
Environmental issues in the United States include climate change, energy, species conservation, invasive species, deforestation, mining, nuclear accidents, pesticides, pollution, waste and over-population. Despite taking hundreds of measures, the rate of environmental issues is increasing rapidly instead of reducing. The United States is among the most significant emitters of greenhouse gasses in the world. In terms of both total and per capita emissions, it is among the largest contributors. The climate policy of the United States has a major influence on the world.

Invasive species are a crucial threat to many native habitats and species of the United States and a significant cost to agriculture, forestry, and recreation. An invasive species refers to an organism that is not native to a specific region and poses significant economic and environmental threats to its new habitat. The term "invasive species" can also refer to feral species or introduced diseases. Some introduced species, such as the dandelion, do not cause significant economic or ecologic damage and are not widely considered as invasive. Economic damages associated with invasive species' effects and control costs are estimated at $120 billion per year.
