Geobotanically Helsinki is situated in an oak zone between the Central European deciduous forest and the northern coniferous forest zones. Helsinki nature displays features of both forest zones. Biodiversity in Helsinki relies on versatile rock and soil formations as well as the city’s situation on the coast.
Helsinki forests and shorelines still feature diverse types of nature in its natural state. In addition, human activity has promoted the diversity of species in parks, yards and gardens.
The City Biodiversity Index measures the biodiversity of urban nature.
