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.
The top layer of the understory is the sub-canopy composed of smaller mature trees, saplings, and suppressed juvenile canopy layer trees awaiting an opening in the canopy. Below the sub-canopy is the shrub layer, composed of low growing woody plants. Typically the lowest growing (and most diverse) layer is the ground cover or herbaceous layer.

It has an unusually diverse tree flora, with as many as 30 tree species at a single site including many relics of the ancient forest that once covered North America more widely. Along with the forest there is a rich undergrowth of ferns, fungi, herbaceous plants, shrubs and small trees as well as areas of glade, heath, shale, peat bog and ...
The Trees of North America. For the purposes of this category, "North America" is defined in accordance with the World Geographical Scheme for Recording Plant Distributions (WGSRPD), which calls it Northern America, namely as one of the nine "botanical continents". It includes the following regions:
Due to the highly variable climatic regimes across the Great Plains, many aspects of climate change are not expected to affect all areas of the eco-region equally. In regards to precipitation, this means an exacerbation of extremes where dry areas in the south are expected to get drier and wetter areas in the north to get wetter.
Due to shading from the canopy, the microclimate of temperate deciduous forests tends to be about 2.1 °Celsius cooler than the surroundings, whereas winter temperatures are from 0.4 to 0.9 °Celsius warmer within forests as a result of insulation from vegetation strata.

The short, stout oaks that grow in the Cross Timbers were not usable as timber, and those that were not cleared for farmland constitute one of the least disturbed forest types in the eastern United States, with some 890,000 acres (3,600 km 2) of old-growth forest scattered throughout the region. [5]
