The IRG is organised in Sections, each with a specific scope. At present there are five Sections that reflect main areas of current importance in wood protection.The Section Leaders (Chair, Vice-chair) are responsible for co-ordinating the activities within their Sections and for encouraging the initiation of new work.
The Scientific Programme Committee (SPC) has the responsibility for co-ordinating the activities between the Sections.Within each Section any Member may make proposals for projects and for Working Parties so long as they have a clearly defined scope and a clearly expressed target date. Working Parties are usually formed around a specific topic such as Physiology of decay. Activities can include research symposia, discussion groups or collaborative research projects. WPs are intended to be easily created or dissolved and serve as a vehicle for bringing IRG members together.
