Forest Reproductive Materials Sites GB

Forest Reproductive Material (FRM) is the generic name for the seeds, cones, cuttings and planting stock used in forest establishment.

The attributes of each polygon in this dataset are restricted to the National Register Identification Number (NRID), a national grid reference (NGR) and a symbol.
SI Comes from general or specific locations within a single region of provenance or seed zone altitude band in which no specific superior qualities are recognised.
SE are collected from stands showing superior characteristics, e.g. better form, growth rate and health.
QU derives from the selection of superior individual trees which have not undergone any form of testing.
TE derives from the selection of individual trees or stands that have undergone evaluation for genetic quality or have been shown to be superior, in comparison to
accepted standards.
