Scope and Objectives

Uneven-aged forest management is practiced virtually in all forests of the world with numerous variations in its species composition and stand structures under local ecological, social, and economic constraints. Hence, the definition and practice of uneven-aged forest management is very broad. In addition to the classical single tree selection practices with shade-tolerant tree species, uneven-aged management involve methods that can create multifunctional, semi-natural forests with a high degree of structural complexity.

The conference 'Uneven-aged Forest Management: Alternative Forms, Practices, and Constraints' will provide a platform for scientists and practitioners for the presentation and discussion of ideas, concepts, and research results, and share experience on various themes of this flexible form of forest management.

Uneven-aged forestry alternatives in the boreal forests of Northern Europe will be
demonstrated and subjected to discussions during the field excursions. Earlier conferences on uneven-aged management have been arranged outside boreal forests and thus this new location will provide fresh development and ideas.

Target Audience

Forest scientists, managers, practitioners and all those interested in the principles and alternative forms of uneven-aged forest management.


Themes for the working sessions on uneven-aged forest management include:

  1. Alternative Forms of Uneven-aged Management
  2. Ecology
  3. Regeneration
  4. Growth and Yield
  5. Harvesting
  6. Risks
  7. Economy
  8. Experimentation
  9. Modeling

Confirmed speakers and their tentative themes are

Kjell Andreassen, Norwegian Forest Research Institute, Ås, Norway

  • Growth and yield aspects of uneven-aged silvicultural systems
  • Major constraints in estimation of growth and yield in these

Lars Lundqvist, Swedish University of Agricultural Sciences, Umeå, Sweden

  • Alternative forms and uneven-aged and -sized structures in
    boreal forest management

Douglas A. Maguire, Oregon State University, Corvallis, OR, USA

  • Experimental and modeling approaches and questions
    inresearch on uneven-aged silvicultural systems

Hans-Jürgen Otto, Professor of Forest Ecology and Silviculture, between 1997 and 2001 President of Pro Silva Europe

  • Natural forest dynamics and the evolution of silvicultural
    systems in the ecological context

Tuula Piri, Finnish Forest Research Institute, Vantaa, Finland

  • Ecological risks in uneven-aged forest management
  • Role of root rots and possibilities to their avoidance

Matti Sirén, Finnish Forest Research Institute, Vantaa, Finland

  • Modern harvesting technology in uneven-aged or uneven-sized
    stand structures
  • Economic aspects of harvesting under these conditions

Timo Saksa, Finnish Forest Research Institute, Suonenjoki, Finland

  • Results of, and constraints for regeneration in uneven-aged
    management under boreal conditions

Conference Structure

The conference will be international and interdisciplinary and will be conducted in English. The program will be structured in plenary and concurrent working sessions, including one poster session and a one-day field excursion. Additionally, a 5-day Post-Conference Tour to Northern Finland and Sweden is offered.

Presentations and Proceedings

The conference themes indicate preferred topics for contributed papers, posters, and presentations. Extended abstracts are made available at the beginning of the Conference Selected full papers are to be published after the conference in a special issue of a refereed journal. See Papers and Posters.
