Forest management and silviculture in the north  

    – balancing future needs

September 6 – 8, 2011 in Stjørdal, Norway


An international forest research conference organised by IUFRO WP 1.01.01 Boreal forest silviculture and management and the SNS network group Sustainable forest management in northern Fennoscandia (NORFOR). Host organisation is the Norwegian Forest and Landscape Institute.


Boreal forest management and silviculture practises face new challenges in a changing world. The predicted climate change, increasing demands for energy, increasing populations which needs areas for recreation activities, and the importance of the forest ecosystems for maintaining biodiversity and environmental services all influence silviculture and management.

The northern forest ecosystems can play a vital role in mitigating climate change, both by being a significant carbon sink, but also by providing a source of renewable energy. Silviculture aiming at maximising biomass production for energy and carbon sequestration may be one important means to face climate change. However, silvicultural decisions might also have important implications for other services provided by the forests, including biodiversity, recreation, or other types of economic activity such as reindeer husbandry. This raises the question on how to manage and tend our forests to best achieve the right balance between these different, and possibly conflicting, objectives.

A changing climate will influence the duration of the growing season, soil processes and nutrient availability, as well as the risk of injury and calamities by biotic and abiotic factors. This is particularly true in the boreal zone, which most likely will face major changes in climatic conditions during the coming decades. In a warmer climate, insects and pests seem to disperse at a fast pace, posing new or increased problems for forest management. Climate change also creates new challenges for choosing the right species and provenances as well as the best silvicultural methods for regeneration and tending of young stands. Exploring the effects of treatments and management strategies aimed at sustainable biomass production in a changing climate thus remains an important research task.

Forest policies, regulations and certification schemes can also play a large role in how well forests  can contribute to mitigation of climate change or how quickly managers can react to produce the best compromises among wood harvesting, intensive plantations, biomass capture, ecosystem functions and ecological reserves.  Forest policies need to be adjusted to meet intended objectives.

We welcome researchers, managers, students and others interested in the management and silviculture of our boreal forests to discuss silvicultural solutions needed to sustain the range of forest services required by society in a changing world.


Scientific topics


1. Silviculture in the north in times of climate change:

  • Climate change: effects on productivity and carbon sequestration in northern forests.
  • Insects and pathogens in northern forest systems under global warming - consequences for forest production and implications for silviculture.  
  • Cost-effective regeneration, pre-commercial thinning and young stand management to maintain or increase biomass production of northern forest ecosystems.


2. Multifunctional forestry and environmental services:

  • Developing adaptive silvicultural systems to maintain biodiversity values and production levels.
  • Reducing conflicts between wood production and non timber values such as reindeer husbandry, berry production and recreational activities.
  • Implementing coherent forest policy and certification schemes that are consistent with forest productivity, stand management, climate mitigation and biodiversity goals.
