Young forest stands need care

Soili Haikarainen, Saija Huuskonen and Johanna Routa from the Natural Resources Institute (Luke), Finland, examine the benefits of carrying out juvenile stand management practices to secure the stand’s future, based on a recent research paper published in Forests.

Field trials: Cable-assisted timber harvesting on steep terrain

In cable-assisted timber harvesting forces on the cable are enormous. But how strong exactly are they?

As part of TECH4EFFECT WP3 , Markus Engel and Andreas Mayerhofer (ÖBf – Austrian Federal Forests ) and Thomas Holzfeind from BOKU carried out investigations on winch assisted harvesting machines in the ÖBf forest district Flachau (Austria). They recorded the inclination of the machine during operation on steep terrain using a tilt sensor installed on the winch assisted Valmet 840TX forwarder. At the same time, the tensile forces in the cable were measured with a load shackle. In addition, all activities of the machine were recorded by an action camera, which will be analysed later together with inclination data and the tensile forces. The results are intended to shed light on the tensile forces that occur in the cable of the machine as a function of the work processes and the machine inclination.

First field trials with bucking app

The Bucking App is a software for mobile devices to calculate into which length and parts to cut a tree in terms of revenue during motor-manual harvesting operations. Jointly developed by BOKU, Latschbacher and the Austrian Federal Forests (ÖBf), first field tests were conducted recently in Austria.
