Habitat construction should not be considered a replacement for the conservation of naturally existing habitat but can play a key role in helping to conserve biological diversity. Careful plantings can provide expanded habitat for a wide range of species, from soil microlife to insects to mammals. A well-designed landscape area, modeled after healthy, diverse natural forests will spontaneously attract and support biodiversity.As a general rule, the more forest-like in form and diverse in species a planting is, the more kinds of life it will attract and support.
