Allozyme variation at 14 loci was estimated in 29 populations of Norway maple, covering the whole distribution area of the species in Finland. The results were used to evaluate the Finnish gene-conservation program for Norway maple. The average value for He over all populations was 0.128; the population estimates ranged from 0.042 to 0.207. There was no statistically significant correlation between population size and within-population variability. The average genetic distance between populations was 0.034; the correlation between genetic distances and geographic distances was non-significant. In a hierarchical analysis, the differentiation between populations within geographic groups (Fpop=0.163) clearly exceeded the differentiation between geographic groups (Freg=0.030). In light of the present results, the genetic conservation program, which is based on ex situ-collections, seems to be justified
