Summary and Background Part 5: Nature Conservation Designation of zones Section 117: Grounds for designation of MCZs
332.This section sets out the circumstances in which Ministers may designate an MCZ. This must be for the purpose of conserving species of marine flora and fauna, particularly if they are rare or threatened, or for conserving or protecting marine habitats or features of geological or geomorphological interest. An MCZ may also be designated for the purpose of conserving the diversity of marine flora or fauna or habitat, whether or not they are considered rare or threatened (subsections (1) to (5)).
333.In this Act, the terms “geomorphological” (used in Parts 5 and 9) and “physiographical” (used in Parts 6 and 7) have the same meaning. Each term is consistent with the previous legislation in the relevant field.
334.Subsection (2) provides that the order designating the MCZ must state both the protected features and the conservation objectives for the MCZ. The level of protection for an individual MCZ will depend on the site’s conservation objectives, which may take account of relevant conservation, social and economic considerations. The conservation objectives will need to be clear to ensure that all public authorities understand the implications of the duties placed on them by sections 125 and 126.
335.Subsection (7) allows Ministers to take account of the economic or social consequences of designation. This ensures MCZs may be designated in such a way as to conserve biodiversity and ecosystems whilst minimising any economic and social impacts. Where an area contains features that are rare, threatened or declining, or forms a biodiversity hotspot, greater weight is likely to be attached to ecological considerations. Where there is a choice of alternative areas which are equally suitable on ecological grounds, socio-economic factors could be more significant in deciding which areas may be designated as an MCZ.
336.Subsection (8) clarifies that the reference to “social” consequences of designating an MCZ includes any consequences of doing so for sites of historic or archaeological interest.
