Background information and definitions
This section considers the effects of different disturbance intensities, when the lower intensity may be suitable to conserve the target vegetation. Different plant species have differing tolerance to disturbance, so the frequency and intensity of disturbance can affect the plant community composition (Connell 1978).
To be summarized as evidence for this action, studies must have compared cutting/mowing at different intensities (e.g. the proportion of the vegetation that is cut) but with the same frequency and with at least some overlap in the timing of disturbance (e.g. summer vs summer + winter). Note that studies comparing areas that remain uncut to areas that become cut, at any intensity, are not summarized as evidence for this action.
Related actions: Reduce intensity of vegetation harvest, including studies of cutting where vegetation is removed (freshwater marshes – brackish/salt marshes – freshwater swamps – brackish/saline swamps); Reduce frequency of cutting/mowing (freshwater marshes – brackish/salt marshes); Change season/timing of cutting/mowing (freshwater marshes – brackish/salt marshes); Cut/mow herbaceous plants to maintain or restore disturbance (freshwater marshes – brackish/salt marshes); Use cutting/mowing to control problematic herbaceous plants (freshwater marshes – brackish/salt marshes – freshwater swamps – brackish/saline swamps).
