Regions of Provenance Great Britain is divided into four Regions of Provenance. http://www.forestry.gov.uk/forestry/INFD-72KLDL These are defined areas within which similar ecological and climatic characteristics are found. They provide a framework for specifying sources of Forest Reproductive Material (FRM). For native species, these Regions of Provenance have been split into a total of 24 non-statutory native seed zones. Seed zones are in turn divided where appropriate into two altitude zones, below 300m and above 300m. There is a different set of seed zones for native Scots Pine. Definitions of Origin and Provenance The origin of FRM describes that part of the natural range of the species from which the material originally derived. The term provenance is used to describe the location of the source from which the reproductive material was collected.
