Clearance of drainage pits and vegetation barriers around perimeter Old seeds heads should be left to overwinter to provide foraging potential for birds and overwintering sites for invertebrates.

Cutting of wildflower turf and removal of this vegetation may be required on turfed roofs or those with more vigorous grass growth Invertebrate/wildlife may be a requirement under BREAAM Landscape and Ecology Management Plans. This can provide invaluable information on green roof ecology and help inform future green roof design. Data should be shared with the local records centre.
