Reforestation proceeded quickly, and by the time of the first Harvard Forest maps in HF was almost entirely wooded. Most are of low or average fertility and under years old.
Many plant lineages that were unable to adapt to new conditions became extinct, but others evolved in response to the climatic changes, eventually dominating the new temperate forests. In addition, during extended periods of darkness and cold, there are increased demands for energy, health care, and textiles.
The black bear is an animal that is well adapted for the temperate deciduous forest biome. Where parent materials are sandy, evergreen vegetation tends to dominate the landscape. Each year deciduous trees lose their leaves, and grow them back.
Hemlock is now locally dominant in many stands that have been continuously forested; oaks, red maples and pines are the common dominants in stands that developed in old fields.

They are also common in Florida, and along the coast into the Carolinas.
Trees lock large amount of carbon dioxide into the air by trapping it as organic matter and living trees. It also reduces the trees' resistance to disease, pests, and frost. Clear cutting of forests is also a threat to this biome.
Altogether, the Volga system drains about 1. Not only are these tiny water outlets dependent on the ground water table for their annual flow, but also the cover of the forest canopy aids the process by repelling the intense heat of the summer sun and thus decreasing the evaporation rate.
