The list of BAP Priority Habitats includes all UK habitats which are considered to be most threatened, or requiring specific conservation action, identified under the UK Biodiversity Action Plan.

A number of criteria are considered in formulating the BAP Priority Habitats list, including;

• Habitats for which the UK has an international responsibility
• Natural and semi-natural habitats in the UK which are considered threatened (rare or declining)
• Habitats which are important for key species
• Habitats which are 'functionally critical' for the well-being of certain species - for example overwintering grounds.

The list of UK BAP Priority Habitats is revised on a regular basis - see http://www.ukbap.org.uk/ for the latest information.
