Instream wood management
Instream wood management involves the realignment, relocation and/or removal of instream large wood (> 0.1 metre in diameter and 1 metre in length). In general, it is strongly encouraged to leave instream wood where it is. Instream large wood should only be managed if it has collected to the extent where it threatens infrastructure, or it is directing flows into an exposed bank causing unacceptable erosion.
The general aim of managing instream large wood should be to manage the risk that it poses rather than its removal. Therefore, the realignment and relocation of instream wood are preferred management methods. The removal of instream wood should be the last resort. In some high risk circumstances removal may be acceptable, especially if it is an introduced species. These species may not provide the same habitat, hydraulic or geomorphic benefit as native timber.
