  • read specific guidance on responsibilities for protecting wild birds and their habitats - for example where bird species may be aof special featurescientific ofinterest an SSSI and could be affected by work on other land where they feed or nest

Natural England consults public bodies in writing about new SSSIs and changes to existing ones, sharing information about the sites. You can use this information to makeassess an assessment of the potential impact of your activities and others’ plans.
