A stand of trees that are about the same age (usually a range of 20% of rotation age). An even-aged stand may be naturally or artificially regenerated. Reproduction Cutting Methods that result in even-aged stands include: clearcuts, seedtree cuts, and shelterwood cuts.
A stand of trees in which there are only small differences in age, usually within 20 percent of rotation age.
Stands of trees of an identical age having been planted at the same time or germinated within a short period of each other (eg. in response to a fire). Small differences in age may not be of any practical significance and can be ignored.
For hardwood (including upland and bottomland) and cypress forests, a stand in which the ages of 90% of the canopy trees vary by no more than plus or minus 20% of the average age. For other (including pine and pine-hardwood) forests, a stand in which the ages of 90% of the canopy trees vary by no more than plus or minus five years from the average age. Clearcutting, seed trees, and shelterwood regeneration systems result in even-aged stands.
a stand of a single age created through treatment such as a clearcut, or a natural event, such as a hurricane, that creates conditions that eliminate trees of varying ages and replaces them with trees that all begin to grow at the same time.
A group of trees of the same age or nearly the same age
a stand of trees consisting of one or two age classes. Even-aged stands are often the result of fire, or a harvesting method such as clearcutting or shelterwood.
a group of trees that do not differ in age by more than 10 or 20 years or by 20 percent of the rotation age.
a stand of trees composed of a single class in which the range of tree ages is usually +/- 20 percent of rotation
a stand of trees in which most of the trees are about the same age. Even-aged stands result from disturbances occurring at one point in time, such as wildfires, a clearcut, a seed-tree cut, a shelterwood cut or stump sprouts.
a stand in which the age difference between the oldest and youngest trees is minimal, usually no greater than 10 to 20 years. Even-aged stands are perpetuated by cutting all the trees within a relatively short period of time.
