Biodiversity

The biological diversity (or biodiversity) value of urban greenspace is immensely variable, but all greenspace by definition contains some biodiversity. The biodiversity present will often depend on the functions of a particular site, as well as its history and location. Nearly all greenspace sites can increase their biodiversity, often quite simply.

‘Biological diversity means the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems.’ Convention on Biological Diversity

Particular species or groups of species can sometimes be managed together.

Greenspace benefits biodiversity, increasing species populations and offering routes through otherwise inhospitable urban land use.

The benefits of biodiversity for people are varied, but may be difficult to quantify. Educational and recreational opportunities are apparent, but the extent to which contact with a wide range of species and habitats benefits human well-being are not currently well understood. However, for many people there is a moral imperative to preserve species and their local populations.

Sites may be managed for a particular species or group of species. But managing for one group may conflict with another. As a general rule, increasing biodiversity can be achieved by diversifying the range of habitats or vegetation structures available at a site. This can be achieved by, for example, varying mowing regimes, planting or seeding with native tree and shrub species, or occasional soil disturbance. Animal diversity may be increased by providing a range of fruit sources, for example by not clipping berry-bearing shrubs until January, and by allowing wildflowers to flower for nectar provision and to bear seed as food for birds. Site drainage can also have an important impact.
