Restoring vegetation on Excavated/disturbed (State 4) to
Vegetated Shingle (State 3)
This change in states is principally concerned with the restoration of 'natural'
vegetation and is thus related to conservation needs. A number of experiments
have attempted to restore
vegetation using a variety of techniques.
| Guidance: Such information as exists from a small number of sites
suggests that left to their own devices vegetation can recolonise excavated
shingle so long as it remains above the water table. Time, and freedom from
disturbance are key and can result in an overall increase in biodiversity.
For a discussion of this, and other biodiversity issues relating to gravel
extraction from shingle structures, see the example of Dungeness (Doody
2001 Chapter 9.4.1). |
Comment: The restoration of gravel
pits on shingle structures is not a subject for this guide, but for
guidance on management see (Andrews & Kinsman
1991).
