Species richness in urban green spaces : relevant aspects for nature conservation
Maintaining species richness became a main subject of nature conservation due to a decline in biodiversity on different scales. In cities high species richness can be found in urban green spaces. As German cities experience population increase in some places and population decrease in other places, green spaces are under threat or, respectively, could be developed. Both phenomena give rise to the need and the opportunity for nature conservation actions. Therefore, the study of the driving factors which lead to high species richness in urban green spaces becomes ever more important. Species richness in urban green spaces is influenced by various driving factors. Factors known to be decisive for promoting species richness include patch size, patch shape, distance to the urban edge and to other urban green spaces, as well as habitat heterogeneity within urban green spaces and in the surrounding area. These factors are derived from species-area effect, distance effects, and effects due to habitat structure. As there are numerous variables which have an impact on species richness in urban green spaces, a current challenge is how to reduce the influencing variables to the smallest relevant set. This set could be adapted for different taxonomic groups, as species richness reacts differently to driving factors in urban green spaces. Reference to the value of certain species for nature conservation, subgrouping within taxonomic groups regarding species’ first occurrence, conservation status or specific traits may all be useful. A lack of research still exists regarding a combination of several response variables and a combination of influencing and response variables. Research gaps include an investigation of different taxonomic groups with different mobility abilities, of endangered species richness, of proportions of different species groups compared to numbers, and of an ‘overall species richness’ containing different taxonomic groups. In addition, not only single factors drive the occurrence of certain species in ...
