National Register of Approved Basic Material for Great Britain
Introduction
The Forestry Commission maintains the National Register of Approved Basic Material for Great Britain (The National Register). This is published in accordance with the Forest Reproductive Material (Great Britain) Regulations 2002 and European Union directive 1999/105/EC, which controls the marketing of Forest Reproductive Material in the EU.
There are two ways to view the National Register, either
by downloading and searching the National Register spreadsheet. The link on the right hand column of the spreadsheet ('NR entry') will then take you to a two page pdf showing stand, location, contact and site information, together with a map.
or by downloading the full 472 page National Register (without maps) (2,059k - pdf)
(The National Register is kept under constant review and will be regularly updated. The version available above is current as at 30 June 2009.)
Each entry of Basic Material (or unit of approval) in the National Register is given a unique register reference, providing information on
- species (a three letter code i.e. bpe = Betula pendula). View the full list of species and their codes.
- type of Basic Material
- region of provenance, native seed zone (where appropriate) and altitude zone (if native to GB)
- serial number (except for seed sources)
- category of FRM
- origin, where appropriate.
Stands and Seed Orchards numbered under the previous Regulations, together with native Scots pine seed collection areas, will retain their original serial numbers within the new expanded form of National Register identity.
Entries for Source-identified Basic Material are at the region of provenance level, with additional entries at the seed zone level for native species, and are not shown in this version. All collections of Source-identified material of the same species in the same region of provenance or seed zone will use the same Basic Material identity code.
Further information is available on the construction of National Register identities (NRID's) and Ecological Site Classification (ESC).
