1.06.00 - Restoration of degraded sites



Mark Your Calendars for a Virtual Symposium!

Forest Seedling Root Development and Function for Reforestation and Restoration;
online; 19-21 October 2021; 8:00AM to 10:40AM (PDT, UTC-7)
IUFRO Units involved: 1.01.03, 1.06.00 and 3.02.00.

This IUFRO symposium is intended to provide a forum for exchange of ideas related to principles of root development in nursery seedlings and juvenile forest trees. Emphasis will be placed on the development of effective and environmentally sound technologies to optimize seedling quality and promote reforestation and forest restoration operations. Speaker topics will focus on seedling root development in the nursery and in the field. The program is aimed toward an international audience of nursery and forest practitioners, scientists, and educators. Presentations will be of excellent scientific quality while also providing new, useful information which can be readily and widely applied to nursery and forest practices.

The symposium is being organized by Western Forestry and Conservation Association, Purdue University, and USDA Forest Service with support from IUFRO divisions 1.01.03 (Temperate Forest Regeneration), 1.06.00 (Restoration of Degraded Sites), and 3.02.00 (Stand Establishment and Treatment).

About Unit

RG 1.06.00 Restoration of Degraded Sites applies silvicultural knowledge in traditional and innovative ways to overcome deforestation and degradation of forested landscapes. Restoration is understood in the broadest sense, from reclaiming mined land to altering composition or structural complexity of stands and diversity of landscapes. The unit has organized five major international conferences (Denmark 2002; Korea 2007; Spain 2011; and the US, 2014) and several regional meetings.

State of Knowledge

Throughout the boreal and temperate zones, forest restoration efforts attempt to counteract negative effects of conversion to other land use (afforestation and remediation) and disturbance and stress on existing forests (rehabilitation). Appropriate silvicultural practices can be designed for any forest restoration objective. Most common objectives include timber, wildlife habitat for game species, or aesthetics. Increasingly other objectives are considered, including carbon sequestration, biological diversity, non-game mammals and birds, endangered animals and plants, protection of water quality and aquatic resources, and recreation. Plantation forestry remains the most effective approach to restoration of forest cover to large areas, and recent trends toward more complex plantations are explored. Rehabilitation of degraded forests increasingly relies on re-establishing natural disturbance regimes and emphasizes "close-to-nature" approaches to regeneration and stand management.
