Scientific results have shown that gene conservation is compatible with economic management. A management model was proposed and will possibly be included in the technical guidelines. In Tunisia , the cork oak stands have quite high economic importance, but surface is in regression. The stands are highly disturbed and are declining due to lack of regeneration. More systematic management started in 1970 and standard rotations were established.
Regeneration is carried out through direct sowing and seedlings.
Research is currently addressing the problems with acorn storage and plantation techniques. Case study on genetic conservation in Spain Pilar Jimenez presented the results of her research on genetic variation of Quercus suber in Spain. An isoenzyme analysis was carried out on 22 populations. Allelic richness, number of polymorphic loci identified and heterozygosity were measured. The most diverse populations were those from south of Spain.
