Planting Strategy. Hedge. Coir roll

Transcription

1 Planting Strategy The planting strategy aims to create a diverse replication of the native aquatic / marginal / terrestrial habitat typical of the River Brent, which is proposed to be implemented using some modern, bioengineered techniques e.g. Coir rolls. Above the 1:100 flood level, flowing swathes of new tree planting is proposed which evokes a waterside character and there are opportunities for colonisation under bridge where gaps in planting have been incorporated. The species lists have been developed in consultation with LBB and the EA with the intention that the whole of the stretch of the River Brent flows as a continuous habitat.

4 Native Climbers Self-clinging climbers are proposed on a number of the walls along the Brent Riverside Park to help soften the environment and provide habitat for biodiversity. Typical species include: 2 per linear meter Parthenocissus henryana Parthenocissus quinquefolia Hedera helix Hedera helix Parthenocissus henryana Parthenocissus quinquefolia 805
