Kalle Kemppainen, Kalle Kärhä, Juha Laitila, Antti Sairanen, Ville Kankaanhuhta, Heli Viiri, Heli Peltola. (2025). Evaluation of the productivity and costs of excavator-based mechanized tree planting in Finland based on automated data collection. Silva Fennica vol. 59 no. 1 article id 25004. https://doi.org/10.14214/sf.25004
Keywords: site preparation; cost-efficiency; mechanization; forest regeneration; planting machine; site selection
Highlights: With proper site selection and competent machine operators, it is possible to achieve a higher productivity than 200 seedlings per operating hour in excavator-based mechanized planting; The hectare-based regeneration costs from excavator-based mechanized planting can be 3% lower than those of conventional manual planting chains; The most cost-efficient planting chain was a continuously advancing mounder combined with manual planting.

Back Tomas Ersson, Lars-Göran Sundblad, Jussi Manner. (2022). Cost analysis of seedling supply systems adapted for mechanized tree planting: a case study from southern Sweden. Silva Fennica vol. 56 no. 2 article id 10663. https://doi.org/10.14214/sf.10663
Keywords: logistics; silviculture; reforestation; tree planting machine; containerized seedling; seedling handling; system analysis
Highlights: The total cost of cardboard box concepts that increase the productivity of tree planting machines is higher than of the cultivation tray system (5–49% in the basic scenario); Increasing the boxes’ packing densities and/or the planting machines’ hourly cost increases the boxes’ cost-competitiveness; Packing density is a key factor in achieving highly cost-efficient seedling supply systems for mechanized tree planting.

Tiina Laine, Kalle Kärhä, Antti Hynönen. (2016). A survey of the Finnish mechanized tree-planting industry in 2013 and its success factors. Silva Fennica vol. 50 no. 2 article id 1323. https://doi.org/10.14214/sf.1323
Keywords: regeneration; boreal; forestry; silviculture; mechanization; planting machines; critical success factors (CSFs)
Highlights: In 2013, 31 planting machines were operated by 22 businesses and planted 4.7 million seedlings on 2663 hectares in Finland; Critical success factors included expertise of planting machine operators, high quality planting, adequate amount of work, stoniness, and removal of slash; Growth of the industry will depend on improved cost-efficiency, appropriate worksites, marketing, development of planting machines.

Back Tomas Ersson, Urban Bergsten, Ola Lindroos. (2014). Reloading mechanized tree planting devices faster using a seedling tray carousel. Silva Fennica vol. 48 no. 2 article id 1064. https://doi.org/10.14214/sf.1064
Keywords: productivity; cost analysis; seedling feed; silviculture; time study; tree planting machine; containerized seedling
Highlights: Seedling reloading onto the Bracke Planter crane-mounted planting device was twice as fast with the MagMat tray-wise-loaded carousel as today’s seedling-wise-loaded carousel; Tray-wise reloading combined with deplugging seedlings from suitable cultivation trays has the potential to be an efficient and robust way to feed seedlings on any type of tree planting machine.
