Landscape patches should be as large as possible. Patches provide numerous ecological benefits that include ameliorating microclimate, providing habitat, and absorbing rainfall. Connectivity of patches and corridors should be maintained. This facilitates wildlife survival and movement. Unique mosaics of land forms and vegetation types should be included in the preserve.
Mosaics provide important physical conditions that support wildlife species diversity.
They are also are visually interesting. Diverse mosaics should be integrated into the developed environment. This expands the mobility and available area for wildlife. It also facilitates contact with nature which is beneficial to human ecology. The preserve should be considered at multiple scales.
