Detailed explanation-1: -Forests are often managed in an even-aged or an uneven-aged system. An even-aged system is one where the dominant trees in the forest are all about the same age. An uneven-aged system is one where there is a greater diversity of tree age classes in the forest.
Detailed explanation-2: -Selection Systems Selection systems, in contrast, result in uneven-aged stands of regrown trees. In a selection system, only some of the trees in a forest are cut at once.
Detailed explanation-3: -An uneven-aged stand is a mosaic of tiny even-aged clumps and scattered individuals woven together through a perpetual cycle of random disturbances. In nature these disturbances contribute to scattered mortality, allowing for temporal waves of different age-classes dispersed throughout the stand.
