A review on the identification and assessment of the aggressive plant species environmental hazard in water ecosystems (case study: Water hyacinth)

The invasion of non-native species is the biggest threat to biodiversity in the world, which plays a major role in global change. In the present study have been reported some adverse effects of non-native specie on the the sensitive and fragile ecosystem and the current methods have been mentioned the assessing risks of these effects on the environment. For this purpose, a wealth of valuable content has been gathered through a number of online and library searches. Firstly, an overview of the environmental risk assessment approach for the invasive species has been presented to an aquatic ecosystem. Then, the most important undesirable effects can accommodate the common invasive species of Water hyacinth in aquatic ecosystem, as well as the process of assessing the environmental risk to this particular species in a simple and scientific language. Studies have shown that a series of social, economic and health factors, along with ecological parameters, can be effective in identifying species and environmental impacts on sensitive, native and sensitive habitats.
