Regeneration by coppicing (resprouting) of miombo (African savanna) trees in relation to land use

摘要: Abstract This study compared and contrasted natural regeneration by coppicing of tree species in a forest reserve more disturbed adjacent public lands eastern Tanzanian miombo woodlands. Data were collected between August October 1997 using sixty-four 20 m ×50  m plots. Eighty-three percent the 30 harvested woody resprouted after harvesting with 90% 39 lands. Coppicing effectiveness (mean number shoots per stump) varied among depended on plant size at time cutting, stump height percentage stand removed. Comparing 16 effectively sampled both sites, was 4.9±1.6 (S.E.) lands, which is greater than 3.1±1.4 (paired t15=2.433,P=0.014). However, resprouting stumps did not differ t15=1.440,P=0.085), but tended to be higher The percentages sprouting from 0 100%, means 59 (reserve) 74% (public lands). for most utilised species, Combretum molle (fuelwood; 4.0 reserve, 6.1 lands), Julbernardia globiflora 5.6 vs. 5.3 stump), Pterocarpus angolensis (carpentry; absent 7.3 Spirostachys africana (building poles; 1.0 0.4 showed typical variation. levels interpreted as release self-thinning dynamics, has much biomass. Despite high densities are virtually identical land uses result resprouting. Due prolific trees it recommended that woodland should managed coppice rotation silvicultural system.
