common water hyacinth
Systems Affected (standardized):
Regions(s) present (updated by AB):
It can quickly form dense floating mats of vegetation (populations can double in size in two weeks!). These dense mats restrict light to the underwater environment, reduce the light availability for submersed plants and aquatic invertebrates, and deplete the oxygen levels. Impact outcomes
Damaged ecosystem services
Ecosystem change/ habitat alteration
Negatively impacts agriculture
Negatively impacts tourism
Reduced amenity values
Reduced native biodiversity
Competition - monopolizing resources
Source? likely to be reintroduced:
The high ornamental value of the plant still makes it liable to intentional introductions, especially as the species is up for sale on the internet.
Can quickly form dense floating mats of vegetation which deplete oxygen levels and restrict light for submersed plants and aquatic invertebrates. Intentionally introduced as an ornamental.
