Plantation forests typically support less biodiversity than natural forests because they are often managed as monocultures, which serve as poor habitats for wildlife.1

Natural forests provide a complex, multi-layered environment where various species can find the specific conditions they require for feeding, nesting, and cover. In contrast, plantation monocultures lack this structural diversity. Many wildlife species rely on a variety of conditions—such as different stages of forest development or specific micro-habitats—to survive, whereas plantations are often uniform in age and species composition, limiting the availability of food and shelter.1

Furthermore, while natural forest regeneration involves interactions among diverse groups of organisms and the environment, leading to a complex array of species, plantations are designed for timber production rather than ecological complexity. Because some species have very specific requirements essential to their existence, the simplified environment of a plantation cannot support the same breadth of life found in a diverse, naturally occurring forest ecosystem.21
