在塔斯马尼亚27-34米高的成熟干桉树林中，国内薪材采集者非法减少了粗（直径≥10厘米）被砍伐的木质碎片存量，减少了96.9立方米ha - 1或22.7吨ha - 1。国内采伐对死树和活树的数量没有影响。在自然（未采伐）地点很少发现枯树。国内采集者优先清除直径小于70厘米的碎片，使国内采集地的木材碎片体积和生物量比自然采集地少40%。假设在测量的强度下，国内采伐在穿过所研究的森林类型的国家森林道路系统两侧的森林中延伸25米，那么该森林类型的死木储量和整个州的所有权减少了68.8万立方米或16.1万吨。国内采伐可能会损害生物多样性价值，减少依赖砍伐原木的物种的栖息地，并减少森林碳储量。建议国内采伐者获得许可证，从有适当森林实践计划的地区收集薪材。
Summary Domestic fuelwood harvesters illegally reduced coarse (≥10-cm diameter) downed woody debris stocks in Tasmanian mature dry eucalypt forests, 27–34 m tall, by 96.9 m3 ha−1 or 22.7 t ha−1. There was no effect of domestic harvesting on quantities of dead trees or live trees. Few dead trees were encountered in natural (unharvested) sites. Domestic harvesters preferentially removed debris <70 cm in diameter, leaving domestically harvested sites with 40% less volume and biomass of downed woody debris than natural sites. Assuming domestic harvesting, at the measured intensity, extends 25 m into forests either side of the state forest road system that passes through the studied forest type, dead wood stocks in that forest type and tenure throughout the state have been reduced by 688 000 m3 or 161 000 t. Domestic harvesting potentially damages biodiversity values, diminishes habitat available for species dependent on fallen logs and reduces forest carbon stocks. Domestic harvesters are advised to obtain licences to collect fuelwood from areas with an appropriate forest practices plan.
