Background information and definitions
Disturbance can clear dominant plants (including trees and shrubs), maintain light availability and control nutrient levels – and may maintain vegetation in a desirable and/or species-rich state (Hall et al. 2008; Middleton 2013). Therefore, conservationists sometimes want to actively restore disturbance where it has ceased, or maintain disturbance at a site where it would otherwise be lost.
Large trees and shrubs may need to be managed by cutting individual plants, stems or branches with loppers, saws or chainsaws. These actions are the focus of this section. Afterwards, regrowth of trees and shrubs may be managed by grazing, mowing or herbicide (effects covered elsewhere in synopsis).
Related actions: Use cutting to control problematic large trees/shrubs, whose success is not linked to a change in disturbance regime; Cut/remove/thin forest plantations; Cut/mow herbaceous plants (or small woody plants) to maintain or restore disturbance.
