SGGW field trip for silviculture case study

Partners from SGGW visited case study areas for the silvicultural work package (WP2) in the Polanów Forest District to identify most productive silvicultural systems, techniques and technologies and assess them.

This State Forest District is located in the northern part of Poland, with about 91,000 m3 of wood harvested annually, mainly pine, beech, spruce and birch. The field meeting was a great opportunity to interact with the local state foresters and owners of private forest companies. Possibilities of improvements in the efficiency of forest operations with regards to socio-economic changes occurring in Poland were discussed. One of the phenomena that need to be faced is a lack of labour force. Details like comparison of manual thinning (chainsaw and tractor/skidder) and thinning with machinery (forwarder and harvester) from an economic point of view and efficiency in different site conditions were also discussed.

First public deliverable: Identifying and extending key silvicultural systems

The silviculture work package (WP2) focuses on the optimization of the access to wood resources. This goal involves two main aspects:

  1. The evaluation of appropriate silvicultural operations, and
  2. The application of appropriate harvesting techniques – aiming at the promotion of mechanized systems wherever possible.

Appropriate silvicultural measures are principally intended to increase wood production, maintain the biodiversity and resilience but also to enable and facilitate the use of efficient silvicultural and harvesting operations. The development of methods for increasing the wood production and optimizing the interface between harvesting technology and silvicultural procedures is the research emphasis of this work package.

The 51 International Symposium on Forestry Mechanization from 25-27 September 2018 in Madrid has an impressive list of talks from TECH4EFFECT partners, on a wide range of topics. Most of our project is covered in those talks: advances in forestry mechanization, our efficiency portal, fuel efficiency in harvesting, an app for motor-manual bucking and much more. Have a look at the list of TECH4EFFECT-related presentations on our events page!

Field tests: forest road bearing capacity

What´s going on under your truck wheel? BOKU is preparing for field tests in the North of Austria. Special soil sensors have been burried to investigate the impact of harsh weather conditions on forest road bearing capacity. High resolution soil parameters and weather data are captured and transmitted to BOKU for analysis, contributing to work package 3 – harvesting.

Two new partners in TECH4EFFECT!

Confirming the high relevance of research and innovation in TECH4EFFECT, two additional organisations have recently joined the TECH4EFFECT consortium. The Department of Forest Work Science and Engineering from the University of Goettingen (Germany) is continuing the work previously done at Freiburg University on timber harvesting and site impact. The South African Stellenbosch University is a key connection point to the South African forestry sector, especially to provide machine derived data to the efficiency portal and associated research.



Publication: Modifying the settings of CTL timber harvesting machines to reduce fuel consumption and CO2 emissions

Following extensive field trials, LUKE just published results on experiments with Ponsse harvesters:

  • Adjustment of machine settings had an effect on fuel consumption and CO2 emissions.
  • Large energy saving potential in the Nordic and Baltic regions alone:
  • Potential savings may amount to almost 50 million litres of diesel per year.
  • Stem size also had a strong effect on fuel consumption and productivity.
