  1. Use thinning followed by prescribed fire

    A replicated, controlled study in in temperate eucalyptus woodland in Victoria Australia (Glaubitz, Wu & Moran 2003) found no effect of harvesting followed by burning on genetic diversity of black ash Eucalyptus sieberi. Genetic diversity did not differ between thinned and burned and untreated plots (allelic richness: 7.7 vs 8.0; effective number of alleles: 3.2 vs 3.4; expected heterozygosity:0.49 vs 0.50 respectively).  Black ash seedlings were sampled in two 5 ha thinned and burned (cutting to retain ~10% of trees followed by prescribed burning in 1989-1990) and two 5-7 ha untreated plots. Molecular analysis was carried out using 35 Mendelian markers.
