Long-term impacts of increased timber harvests on ecosystem services and biodiversity: A scenario study based on national forest inventory data
2020
Abstract The transition to a climate-neutral economy is expected to increase future timber demands and endanger the multifunctionality of forests. National scenario analyses are needed to determine long-term forest management impacts and support forest policy making in defining guidelines for the sustainable provision of forests’ ecosystem services and biodiversity (ESB). Using national forestry inventory data, the forest management model MASSIMO and a model to estimate harvesting costs, we simulated forest development in Switzerland under five politically relevant timber harvesting scenarios until 2106 (business as usual and four increased timber mobilisation scenarios). Model results were…
The Preservation of Sicilian Forests with Poorly Mechanized Logging Processes
1997
Abstract In the province of Agrigento (Sicily), owing to lack of funds, machinery and permanently employed workers, it is necessary to forecast costs and time required for thinning out about 1500 ha of artificial forest using only chain saws and temporarily employed manpower. This study was made to find out how costs and labour productivity vary with tree species, age, size, forest density, land orography and ground uneveness, in order to decide in which areas the change from artificial to natural forest, by gradually thinning out the non-autochthonous trees, could be done at the least cost. Logging processes have been monitored at nine different test sites of about 1 ha each. The results s…
