What is a Section 41 or BAP habitat or species?

Planners and local plans sometimes refer to Section 41 habitat or species, often interchanging with Biodiversity Action Plans or “Habitats and species of principal importance in England”. What are they referring to ?

The term refers to the Natural Environment and Rural Communities (NERC) Act , which came into force on 1st Oct 2006. In Section 41 (S41), the Secretary of State is obliged to publish “a list of habitats and species which are of principal importance for the conservation of biodiversity in England”.  The list is drawn up working with Natural England, as required by the Act.

This S41 list guides decision-makers such as councils and statutory undertakers, as to their duty under Section 40 of the NERC Act, to “have regard to the conservation of biodiversity in England” in day-to-day decisions.

Things change and as per Section 41(4) the Secretary of State working with Natural England keeps the list under review and revises it if necessary.

Habitats of principal importance

There are 56 “habitats of principal importance” on the S41 list. These are the habitats in England identified in the UK Biodiversity Action Plan (UK BAP in old money) which continued to be priorities in the new UK Post-2010 Biodiversity Framework.

The list includes terrestrial habitats e.g. upland hay meadows and lowland mixed deciduous woodland, and freshwater e.g. ponds and marine habitats e.g. subtidal sands and gravels.  Some of these are broad; some very specific.

Species of principal importance

There are 943 species of principal importance included on the S41 list ( indeed ), again those from the UK BAP, which continued to priorities after the 2010 review.
