These forests are the result of ecological succession, a long progression of different plant species over centuries. One possible sere is from bare ground, it would start with weeds, then shrubs, weedy trees (such as mulberry), then coniferous trees (such as juniper) and additional types such as ash lead to a mixed mesophytic forest.
In the United States, the forest cover by state and territory is estimated from tree-attributes using the basic statistics reported by the Forest Inventory and Analysis (FIA) program of the Forest Service. [2] Tree volumes and weights are not directly measured in the field, but computed from other variables that can be measured. [3] [4]
[7] [8] In 1859 Henry David Thoreau wrote an address called "The Succession of Forest Trees" [9] in which he described succession in an oak-pine forest. "It has long been known to observers that squirrels bury nuts in the ground, but I am not aware that any one has thus accounted for the regular succession of forests."

Three forest stands Stand dynamics stages during succession.. A forest stand is a contiguous community of trees sufficiently uniform in composition, structure, age, size, class, distribution, spatial arrangement, condition, or location on a site of uniform quality to distinguish it from adjacent communities.
ODNR map shows where Ohio trees are changing to fall colors. Sept. '24 Fall Color Progress Map ODNR. In most areas of Ohio, the tree canopies have started to change color.
Forest succession is the process by which species recover and regenerate after a disturbance. The type of disturbance, the climate and weather conditions, the presence of colonizing species, and the interactions among species all influence the path that succession will take. Species diversity and composition fluctuate throughout succession.
The Bradford pear makes a beautiful sight for fall-lovers, but they're invasive in Ohio and illegal to plant, grow and sell. Here's why.
