Background information and definitions
This section considers the effects of different cutting/mowing frequencies, 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 frequencies (e.g. 1 vs 2 cuts/year) but with the same intensity and with at least some overlap in the timing of disturbance (e.g. summer vs summer + winter). For this action, “reduction” includes stopping disturbance altogether. However, studies comparing areas that remain uncut to areas that become cut, at any frequency, are not summarized as evidence for this action.
Related actions: Reduce frequency of vegetation harvest, including studies of cutting where vegetation is removed; Reduce intensity of cutting/mowing; Change season/timing of cutting/mowing; Cut/mow herbaceous plants to maintain or restore disturbance; Use cutting/mowing to control problematic herbaceous plants.
