This manual presents a standardised system for classifying and mapping wildlife habitats in all parts of Great Britain, including urban areas.

The Phase 1 habitat classification and associated field survey technique provides a relatively rapid system to record semi-natural vegetation and other wildlife habitats. Each habitat type/feature is defined by way of a brief description and is allocated a specific name, an alpha-numeric code, and unique mapping colour. The system has been widely used and continues to act as the standard ‘phase 1’ technique for habitat survey across the UK.

Please Note: The content of the Phase 1 Field Manual is included in within the main A4 Phase 1 Handbook. Both were published first in 1990 by the Nature Conservancy Council (NCC): later versions, with limited additions, were produced by JNCC. Final additions were errata, added in 2016.
