The Eastern Temperate Forests of North America are a vast and diverse region. Stretching inland from the Atlantic coast about 385 miles (620 km), they reach from Michigan in the north and Texas in the south; they cover the land of New England to Florida, Alabama to Michigan, and Missouri to the Appalachian Mountains.
Wet tropical forests in North America span from sea level to an altitude of 1,000 metres (3,300 ft). They have particular geologic, topographic, and soil conditions that characterize them. These characteristics influence biotic structures and relationships and have contributed to the high biodiversity of the ecoregion.
Information included in the Atlas includes accurate, seamless maps, documentation, and geospatial data that crosses political borders. This data is displayed as series of interactive map layers in an easy to use map viewer format. Most layers in the North American Environmental Atlas are at a scale of 1:1:10,000,000 or finer.
