Review of studies on motor-manual felling productivity in eucalypt stands

AbstractGlobally, about 20 million ha of land area is occupied by plantations Eucalyptus . Motor-manual tree harvest-ing techniques (using chainsaws) are still applied in eucalypt plantations, especially difficult terrains or for large- sized trees where mechanised felling may not be an effective and safe possible option to apply. There little information available on motor-manual stands. This article reviewed literature the productivity felling. The results were classified into four regions, including Africa, Asia/Oceania, America Europe. Results international studies indicate that main factors impacting include diameter at breast height (DBH), travelling distance trees, understory density terrain slope. Operator experience also plays a key role operations. range reported varied from 0.6 m 3 /PMH 0 48.9 different regions. provides recommendations improving productivity, which can provide guide sustainable harvesting planning purposes.
