Increasing ecological value of structure

Effectiveness for Biological Quality Elements

At present very little information exists relating to the ecological effectiveness associated with structure modification.

Relating to coastal and transitional waters,  Airoldi et al. (2005), Moschella et al. (2005) and Martin et al. (2005) have conducted studies to investigate the effects and  possible benefits to ecology and habitats of coastal defence structures, in particular low crested coastal defence structures (that protect sedimentary coastlines for erosion and flooding). Their results demonstrate that while in general the construction of low crested coastal defence structures has a negative impact on local habitats and native assemblages, they have been shown to provide some ecological enhancement in particular with regard to a potential nursery role.
