VIRGIN FOREST - OLD GROWTH FOREST

Virgin forest is a type of forest that has attained great age and so exhibits unique biological features. Old-growth forest typically contains large and old live trees, large dead trees (sometimes called "snags"), and large logs. Individual tree mortality creates gaps in the main canopy layer, allowing light to penetrate the main canopy and create favorable photosynthetic conditions for the understory. That is why the understory in old-growth forest is more developed than in immature stands. Old-growth forests are unique, usually having multiple horizontal layers of vegetation representing a variety of tree species, age classes, and sizes, as well as "pit and mound" soil shape with well-established fungal nets. Because old-growth forest is structurally diverse it provides higher-diversity habitat than forests in other stages. Thus, sometimes higher biological diversity can be sustained in old-growth forest, or at least a biodiversity that is different from other forest stages. Many old-growth forest stands are threatened by habitat destruction through excessive logging. The resulting destruction reduces biodiversity, affecting not only the old-growth forest itself, but also indigenous species that rely upon old-growth forest habitat.

Forest that is regenerated after severe disruptions, such as clear-cutting or fire, is often called second-growth or regeneration until enough time passes that the effects of the disturbance are no longer evident. Depending on the forest, this may take anywhere from a century to several millennia. Old-growth forests are often home to rare species, threatened species, and endangered species of plants and animals, making them ecologically significant.
Levels of biodiversity may be higher or lower in old-growth forests compared to that in second-growth forests, depending on specific circumstances, environmental variables and geographic variables (where the forest is located). Logging in old-growth forests is a contentious issue in many parts of the world.
