Justification for conserving the target species in the GCU
To maintain genetic diversity in large tree populations
To conserve specific adaptive and/or phenotypic traits in marginal or scattered tree populations which are often relatively small
To conserve rare or endangered tree species with populations consisting of a low number of remaining individuals
to conserve specific adaptive and/or phenotypic traits in populations/ and races of introduced species
Total number of reproducing trees
1 - 14
15 - 49
50 - 499
500 - 4999

Predominant silvicultural system
Coppice
Clear-cutting with artificial regeneration (planting or seeding)
Clear-cutting with natural regeneration (seed trees or strips)
Shelterwood systems
Close-to-nature forestry (continuous cover forest, selective logging)
No silviculture
Population management
No intervention allowed
Minimum intervention allowed
Conservation through active intervention carried out
Unit type
Gene reserve forest
Biodiversity conservation (habitats and/or species)
Seed stand
