Use of data and technology to grow and harvest more wood

TECH4EFFECT is a collaborative research project to increase access to wood resources. Data and knowledge based management will enable more efficient silviculture and harvesting, but also reduction of soil and environmental impact from forest operations with the TECH4EFFECT benchmarking system.

The strategic objective of TECH4EFFECT is to improve the efficiency of European forest management by enabling a data-driven knowledge-based revolution of the European forest sector while also providing key incremental improvements in technology. The TECH4EFFECT (Knowledge and Technologies for Effective Wood Procurement) project recently published a new animation video: https://youtu.be/54DDLTon7rg

The TECH4EFFECT project has received funding under the Horizon2020 BBI (Bio-Based-Industries) programme by the European Union. The TECH4EFFECT project objectives are relevant also for the Northern Periphery regions and GREBE partner countries.

Finnish roundwood harvests to a record level in 2016

The total amount of roundwood removed from Finnish forests for the forest industry or energy production was 70 million cubic metres in 2016. The figure was a new record and more than two million cubic metres higher than during the previous year.

According to statistics by the Natural Resources Institute Finland (Luke), a total of 62.1 million cubic metres of roundwood were harvested for export or for the production of forest industry products. Of this volume, sawlogs accounted for 26.3 million cubic metres and pulpwood for 35.8 million cubic metres. The total volume increased by 3.3 million cubic metres or six per cent on the previous year. The industrial roundwood removals exceeded the annual average of the previous ten-year period by 9 million cubic metres or 17%.

A total of 8.2 million cubic metres of stemwood were harvested to be used as wood chips in heat and power plants or as fuelwood in residential housing. The volume decreased by 11% on the previous year, but was eight per cent higher than the average of the previous ten-year period. In addition to stemwood, logging residues and stumps were harvested from forests for energy production, totalling slightly less than three million cubic metres.

Volumes of wood to be used as wood chips are now recorded in the statistics on the basis of information reported by harvesting organisations, while in previous years the statistics were based on consumption volumes. This means that the information relating to the area where the forests are located and the right time, similarly to industrial roundwood, says Senior Statistician Jukka Torvelainen of the Natural Resources Institute Finland (Luke).

Total roundwood removals 70 million cubic metres, more than 85% of the maximum sustainable felling potential

The forest land used for wood production has close to 2,200 million cubic metres of roundwood. Luke estimates based on the results of the National Forest Inventory 11 that 81 million cubic metres of stemwood can be harvested in a sustainable way annually in this decade. Of this volume, 70 million cubic metres or approximately 87% were harvested in 2016. However, there was considerable regional variation in the utilisation rate of felling potential. Roundwood removals exceeded the estimated annual felling potential in many regions in Southeast Finland and in Häme. The utilisation rate for spruce was higher than that for other tree species, says Torvelainen.

Roundwood drain increased to 86 million cubic metres

The total annual drain is the combination of roundwood removals, logging residue left in the forest and naturally dead trees left in the forest. In 2016, the latter two totalled just over 15 million cubic metres, causing the annual drain to reach almost 86 million cubic metres. The volume was four per cent higher than during the previous year.

The annual increment of growing stock totals approximately 110 million cubic metres. It thus exceeded removals and natural drain by almost 25 million cubic metres even last year.” (Luke News)

Winter climate change might have a negative effect on forest growth and productivity

luke-08-12-2016

“According to an experiment conducted in Luke, denser snowpack or lack of snow cover due to warmer winters could have a major impact on forest ecosystems. Winter climate change might have a negative effect on forest growth and productivity that could partially counteract the positive growth effects predicted due to increasing summer time temperatures.

Winter warming is expected to affect snow cover in boreal forests by increasing ground ice encasement, snow compaction or even events of complete lack of snow cover. Of these predicted changes ice encasement appeared to be the most harmful winter conditions to Scots pine and Norway spruce seedlings. These effects could influence forest regeneration with important implications for boreal forest ecology and the associated economy such as forest regeneration costs. (…)” (Luke News)
