Green roofs – habitat distinctiveness

In GN36 Appendix C – Habitat Type Classification and Reference Index the distinctiveness types which have been set for Extensive and Intensive green roofs in part relate to β€˜likely’ planting taking into consideration possible options for these roofs.

Taking into consideration evolving and changing practices around green roofs (and generally relating to habitat classification) notes A&B in GN36 Appendix C provide the ecologist with the flexibility to use their professional judgement to use alternative information / classification as long as this is justified.

As such, whilst the distinctiveness levels set in Appendix C should be used in normal circumstances, where the ecologist can provide evidence/justification for doing so, they can specify the distinctiveness of the green roof based specifically on the planting that has implemented on that project.
