Mountain forests are mainly located on the lee slopes, where communities are evergreen species of laurel forest. The forests are typically evergreen because the mild climate allows for continuous biological activity. In the absence of a strong environmental selective pressure, the number of species that share the canopy is high. This diversity earns them the name "rainforest", as opposed to "woods" ("Mediterranean wood", "temperate wood", etc.), implying canopies dominated by one or a few tree species. In this sense, the laurel forest is a transitional formation between temperate forests and rainforests. Many tree species do not have a coordinated timing of shedding their leaves, flowering or fruit ripening, with phases occurring at any time of year. The woody plants including conifers of the families Podocarpaceae, Araucariaceae and the subfamily Callitroideae of Cupressaceae and angiosperms such as families Erythroxylaceae, Epacridaceae, Proteaceae, Griseliniaceae, Cunoniaceae, Atherospermataceae, and Winteraceae, and genera such as southern beech ("Nothofagus").
