Proposals that may have significant adverse impacts upon water environment, including upon habitats and species that can be of benefit to water quality must demonstrate that they will, in order of preference:
c) mitigate significant adverse impacts
- Habitats and species can provide a number of services to an ecosystem, including:
- filtering water helping to improve or maintain water quality
- absorbing nurtrients such as nitrogen to prevent the growth of other invasive species
- reducing the impact of hazardous chemicals through sequestration
- Proposals should provide evidence that they have considered the potential for significant adverse impact on habitats and groupings of species that help maintain water quality.
- If it is not possible to avoid impacts, minimisation or mitigation of direct and indirect should be considered. Proposals should include how this will be achieved. For example this could include limiting the size of the development or the time activities take place or by creating alternative habitats (for example mussel ropes), using bioremediation such as mussel cultivation or by creating compensatory habitat.
- Proposals should show where activities and developments will take place in relation to supporting habitats and species, including maps.
- Natural England's Marine ecosystem services record can provide more details on habitats and species that are beneficial for water quality.
- atural England and JNCC are available to provide more information and advice on habitats and species and how to avoid, minimise or mitigate impacts.
- Proposals can include any consultation and advice from Natural England and JNCC.
