Urban habitats (including infrastructure networks)

Throughout Lancashire's long history, changes in agriculture, industry, society and the environment have had a profound and lasting influence over the landscape and urban environment[i]. Our industrial past has left us with many brownfield sites, including open mosaic habitats on previously developed land, which have considerable biodiversity value. Recent increases in housing targets and demand for housing are exerting pressure on brownfield sites for residential development.

The most important habitats in the urban group are the biodiverse open spaces within towns, cities and urban areas. Opportunities for nature recovery in the urban environment include effectively designed green and blue infrastructure. It is therefore essential that nature is at the heart of urban regeneration to create attractive, investable places that are good for people, climate, and the economy[ii].

Many of the broad urban habitat types replicate those from the other habitat groups (for example, trees and wooded habitats, aquatic and wetland habitats such as ponds and canals, rocky habitats such as open sandy/stony ground). For simplicity not all of these have been repeated within the tables below. Please see the 'Species shortlisted for recovery in Lancashire' in the Evidence and Technical Information supporting document for the full urban species assemblage list.
