Willows (Salix) such as the crack willow and grey willow form fast growing clumps of dense vegetation often near water as they tolerate flooding.
Willows spread easily as stem fragments are spread by water, and suckers spread locally. Willow replaces native species in riparian sites and forms vast dense (often pure) stands along channels. Causes blockages, flooding and structural changes in waterways.
