Tree Species Selection for Green Infrastructure: A Guide for Specifiers

This guide and a companion database aim to offer a comprehensive decision-making tool on selecting appropriate species for a range of contrasting planting scenarios. It starts with advice on the general approach to species selection, then presents a catalogue of over 280 species, specifying their use-potential, size and crown characteristics, natural habitat, environmental tolerance, ornamental qualities, potential issues to be aware of, and notable varieties. It is for anyone with an interest in specifying trees for green infrastructure and is likely to include: arboriculturists, architects, civil and structural engineers, designers, landscape architects, landscape contractors, non-profit organisations, planners and tree officers.

Although the non-native species far outnumber the native species in the manual, the introductory section notes that to maximise biodiversity benefits it is important to include species that are native or near-native, and which are known to provide food, berries, nectar and nesting and hibernation sites for local wildlife.

The guide was written by Andrew D. Hirons, Senior Lecturer at University Centre Myerscough and Henrik Sjöman, Senior Researcher at the Swedish University of Agricultural Sciences and Scientific Curator at Gothenburg Botanical Garden, funded by NERC.
