Anssi Ahtikoski, Kari Väätäinen, Perttu Anttila, Juha Laitila, Antti Mutanen, Jari Lindblad, Lauri Sikanen, Johanna Routa. (2024). The effects of the EU’s forest-related policies on harvesting costs in Finland. Silva Fennica vol. 58 no. 3 article id 23018. https://doi.org/10.14214/sf.23018
Keywords: forests; scenario approach; harvesting costs; directives and regulations; EU legislation; structural systems analysis
Highlights: The EU’s forest-related policies set direct and indirect limitations on the harvesting operations and operating environment; The effect on harvesting costs of Directives and Regulations depends on the magnitude of policy implementation; In a high-impact scenario, harvesting costs could increase by as much as 18% from the current level of costs.

Perttu Anttila, Johannes Ojala, Teijo Palander, Kari Väätäinen. (2023). The effect of road characteristics on timber truck driving speed and fuel consumption based on visual interpretation of road database and data from fleet management system. Silva Fennica vol. 56 no. 4 article id 10798. https://doi.org/10.14214/sf.10798
Keywords: fuel consumption; forest roads; CAN bus; forest logistics; greenhouse gas emissions; log truck; road classes
Highlights: Finnish road and pavement classes explain driving speed and fuel consumption of a timber truck; Other significant explanatory variables include the number of road crossings, season, proportion of distance travelled with a loader, and total laden mass of a truck; In the future, higher-resolution tracking data is needed to construct generalisable models for 76-tonne vehicles.

Juha Laitila, Kari Väätäinen. (2020). Productivity of harvesting and clearing of brushwood alongside forest roads. Silva Fennica vol. 54 no. 5 article id 10379. https://doi.org/10.14214/sf.10379
Keywords: logging; energy wood; time study; harwarder; spiral cutter; whole-trees
Highlights: The results can be used as a basis to determine in what kinds of cases brushwood biomass should be recovered and where it should be left to decay; The average volume of harvested brushwood and forwarding distance are the key elements to harvesting productivity with a harwarder; Stump diameter has a strong impact on clearing productivity of brushwood.

Perttu Anttila, Tuomas Nummelin, Kari Väätäinen, Juha Laitila. (2020). The effect of winter weather on timber truck tare weights. Silva Fennica vol. 54 no. 4 article id 10385. https://doi.org/10.14214/sf.10385
Keywords: forestry logistics; payload; tare weight; weather data
Highlights: In a one-year follow-up study of eight timber trucks in Finland, up to 6–12% increase in tare weights was observed in wintertime; Compared with summertime tare weights, the maximum increase varied between 1560 kg and 3100 kg; Potential payload loss was explained by temperature, relative humidity and precipitation.
