On European levelOn European level the the European Forest Genetic European Forest Genetic Resources Resources ProgrammeProgramme (EUFORGEN) (EUFORGEN) PProgramme rogramme was launched in 1994 under IPGRI coordination was launched in 1994 under IPGRI coordination ((now called now called Bioversity International)Bioversity International), as an , as an instrument for implementation of S2 Resolutioninstrument for implementation of S2 Resolution. .

On European level the EUFGIS On European level the EUFGIS (Establishment (Establishment of an European Information System on Forest of an European Information System on Forest Genetic Resources) Genetic Resources) ProjectProject is underway and is underway and Romania is a participantRomania is a participant (ICAS (ICAS being the national being the national focal centrefocal centre))


Romania is a participant in the Romania is a participant in the EUFORGENEUFORGEN PProgrammerogramme which has developed which has developed the conservation methods for tree species. the conservation methods for tree species.

A A dynamic gene conservationdynamic gene conservation strategy strategy is based onis based on::

the maintenance of the evolutionary the maintenance of the evolutionary processes within tree population to processes within tree population to safeguard their potential for safeguard their potential for continuous continuous adaptationadaptation: in their : in their natural habitats (natural habitats (in in situsitu),), or outside their natural range in or outside their natural range in artificial (planted) sites (artificial (planted) sites (ex situex situ). ).


The main objective of FGR The main objective of FGR conservation is conservation is to ensure the adaptability of species to ensure the adaptability of species and populationsand populations in a changing in a changing environment, by environment, by maintaining an maintaining an adequate level of genetic varabilityadequate level of genetic varability

METHODOLOGYMETHODOLOGY

A. ESTABLISHMENT OFESTABLISHMENT OF FGR FGR ::

The method used is in accordance with:The method used is in accordance with:

- the - the Fellow up Committee recommendationsFellow up Committee recommendations for applying the S2 Resolution for applying the S2 Resolution , Strasbourg , Strasbourg (1990)(1990), and, and

- Minimum species requirements - Minimum species requirements recommended by EUFORGEN networksrecommended by EUFORGEN networks


ESTABLISHMENT OFESTABLISHMENT OF FGR FGR ::

the FGRthe FGR is formedis formed by aby a core zonecore zone (the properly (the properly genetic resource which has minimum 10 ha of genetic resource which has minimum 10 ha of surface)surface) andand a buffer zonea buffer zone which surrounds the which surrounds the core zone and has a protection rolecore zone and has a protection role

Establishing a FGR implied several phasesEstablishing a FGR implied several phases (activities)(activities): 1-: 1- fieldfield explorationexploration; 2-; 2- samplingsampling; 3-; 3- description and field materializationdescription and field materialization;; 4-4- evidenceevidence;; 5-5- classificationclassification ((genetic evaluationgenetic evaluation)) of of FGRFGR; 6-; 6- establishment of management measuresestablishment of management measures


B. Setting up of the GIS database and B. Setting up of the GIS database and elaboration of digital maps on national elaboration of digital maps on national level:level:
