127.Section 80 provides that Scottish Natural Heritage (SNH) may issue advice and guidance to public authorities on certain matters relating to MPAs. For example, advice may be provided on matters which are capable of damaging protected features. Such guidance may relate to a single MPA, categories of MPAs or all MPAs, and may be given to a particular authority or authorities in general. This section also requires that SNH must give advice to a public authority if the authority requests it.
