ABSTRACT: Traditional and established methods of weed management are outlined, from hand-weeding, to the use of herbicides and biological control. Recent new developments in detection and control methods are introduced, including robotics, microwaves and lasers. Potential roles for the various techniques and management options for forest restoration are then discussed. Robotics could play an important role in accurately detecting and controlling weeds. Low-volume herbicide application, by unmanned aerial vehicles (UAVs) appears particularly suitable. However, integrated weed management, using several methods will probably be required. This should include selection of the most competitive tree species for initial restoration plantings and screening desired tree species for tolerance to herbicides.
