RECENT ACTIVITIES & PUBLICATIONS:

The Silviculture Working Group (SWG) has conducted meetings annually. Activities of the group over the last two years have focused on building our membership and defining our terms of reference and mission. Activities over the next four years will focus on publicizing the work of the NAFC SWG to increase the accessibility of knowledge, facilitate its input into the policy process and to highlight the potential of silviculture to increase the value of forest commodities now and in the future.

  • 2006 - 2008: Activities for the next biennium will focus on building the profile of the Silviculture Working Group and the NAFC. This will be done through organizing a Workshop in Mexico to publicize the work of the WG and highlight the potential of silviculture to increase the value of forest commodities now and in the future. In addition we plan to update the Web Site to include pertinent information on the issues and challenges facing silviculture in North America both now and in the future.

    We will also explore the possibility of starting an international project linking long term silviculture research sites in Canada , the USA and Mexico to increase the accessibility of knowledge and facilitate its input into the policy process.
  • 2005 - 2006: Our mission statement was revised to make it more responsive to recent trends in international forestry: To develop and disseminate knowledge and technology on silviculture strategies and practices for North American Forests to improve the quality of human life.

    With the addition of three new members, a scoping session was undertaken to explore possible future collaborative projects and deliverables. The following opportunities were identified and work is in progress:

    • Workshop on the Evolution of Mexican silviculture and future directions (2007/08)
    • Web site update (2006-2008)
    • Statement of SWG common issues and scope (2006-2007)
    • Assist in planning for the 2006-07 joint meeting of the Genetics and Silviculture Working groups
  • 2004-2005: Terms of reference of the group were expanded from tropical silviculture alone to include temperate forest silviculture to foster Canadian and US participation in the group.

    With the addition of new members and the election of a new Chair, a scoping session was undertaken to explore possible future collaborative projects and deliverables and to identify opportunities. The following tasks were completed:

    • Presented results of last two meetings for Board of Alternates (BOA) Meeting in Veracruz next week
    • Prepared an outline for a manuscript entitled “ Synthesis of silvicultural issues in the sustainable management of mountain forests in Canada , Mexico and USA .”
    • Sought new members for the Silviculture Working Group to strengthen representation on issues in temperate forest silviculture.
    • Assisted in planning for the 2005-06 joint meeting of the Genetics and Silviculture Working groups
