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).

World Series Vol. 34 - Forest Landscape Restoration as a Key Component of Climate Change Mitigation and Adaptation

Drawing on state-of-the art scientific knowledge through analysis of restoration case studies and review of scientific literature, IUFRO scientists developed a framework to demonstrate how forest landscape restoration (FLR) can contribute to climate change mitigation and adaptation. One of the major results of this study was the identification and detailed description of the many different ways in which FLR contributes to both mitigating climate effects and helping ecosystems and society to adapt to adverse effects of a changing climate. In addition, this work contributed a stoplight tool aimed at better presenting complex restoration initiatives, and how they may contribute to climate change mitigation and adaptation and vice-versa, in a specific local context.

Feasibility Study for a Peer Review of the Bonn Challenge

Recognizing the need for large-scale restoration to counter forest degradation and improve vital ecosystem functions and services, international initiatives have set various targets for improving forest ecosystems. These include the Bonn Challenge, launched in 2011, that set an ambitious target to restore 150 million ha of deforested and degraded land by 2020. Pledges under the Bonn Challenge are commitments to improve land management practices in such a way as to increase demonstrably the flow of a number of ecosystem goods and services. These pledges thus far, have been rather loosely defined, with significant scope for improvement of both the design of the pledges and the subsequent review of these pledges. A group of IUFRO scientists undertook a review of options for a peer review process to assist in the validation and follow up of pledges under the Bonn Challenge. We analysed and evaluated the potential for a systematic peer review process to assess pledges; this was a feasibility study and not the outline of a peer review process itself. We proposed four objectives for peer reviews that may be applied together or individually to any given project or pledge. These are: a) ensuring that the projects/pledges really are undertaking FLR and demonstrating a case beyond “business as usual”, b) confirming that the project is designed well, efficient, effective, and sustainable, c) providing recommendations and/or a roadmap to achieve pledge status (or to qualify as FLR projects), and lastly, d) lesson learning.
