Parrot’s feather: Mechanical excavation
Overall effectiveness category No evidence found (no assessment)
Number of studies: 0
Background information and definitions
Mechanical excavation can be used for digging sediment-rooted plants such as parrot’s feather. Harvesting and digging using excavators, while not species-specific, can achieve considerable reduction of rooted floating-leaved, submerged and emergent plants in narrow waterbodies such as ponds, channels and small rivers (Hussner et al. 2017). The interventions ‘Mechanical harvesting or cutting’ discusses the mechanical harvesting or cutting of parrot’s feather. The use of water-jet ventilation and suction dredging are respectively discussed in ‘Removal using water jets’ and ‘Suction dredging and diver-assisted suction removal’. The use of manual harvesting to control parrot’s feather is discussed in ‘Manual harvesting (hand-weeding)’.
