The Tabor oak (Quercus aegilops L. ssp. ithaburensis [Decne] Boiss.) is a tree species of ecological and aesthetic importance in Israel, but it is among the many Mediterranean oak species for which we lack the genetic knowledge that is needed as a basis for genetic conservation and forest management. Therefore, random amplified polymorphic DNA (RAPD) analysis was used to determine genetic diversity within and among 16 natural populations. According to the allele frequencies in 72 polymorphic loci, these populations were aggregated according to main geographic regions: the Golan Heights, the Lower Galilee, and the Coastal Plain groups. Only a few of the primers used revealed allele frequencies that were significantly correlated with geo-climatic parameters. Three populations, those of the Kachal, Alona Forest, and Hirbet-Zerkess, were clustered with geographically distant groups, which may indicate the possibility that these populations are the result of human activity. The overall total genetic diversity (Ht) was 0.414, the overall within-population diversity (Hs) was 0.362, and the overall proportion of total diversity stemming from differences between populations (Gst) was 0.126. Shannon's Heterozygosity Index (I) was 0.535. The lowest values of the various genetic parameters were in the Horshat-Tal population, and the highest were in the Ha'Movil Junction population.
