Patterns and Challenges of Urban Nature Conservation—A Study of Southern Sweden

Abstract

The current, dominating strategy of nature conservation within urban landscapes is to formally protect remaining patches of unexploited nature in nature reserves. However, integration of nature conservation frameworks into urban planning requires reconsideration of key issues, such as why, where, and how to protect nature in a purposeful way. As part of that process I statistically evaluate current nature conservation in 209 municipalities in southern Sweden by analysing the number, size, age, and land cover patterns of 1869 nature reserves in relation to the degree of urbanisation. The analyses reveal that in urban municipalities the nature reserves are fewer, but larger, and have a higher diversity of land covers. Having large nature reserves may be especially important in urban landscapes, since it is often highly fragmented. The land cover compositions show no differences between urban and rural nature reserves. However, urban nature reserves differ more from their surroundings compared with rural nature reserves, according to the identified changes in representation of land cover types with an increasing degree of urbanisation. The most urgent future challenge identified is to develop urban nature conservation strategies that are integrated into the urban context including other green areas and built-up areas, the land-use history, and the requirements for local ecosystem services across the landscape.
