What is a macrophyte?

A macrophyte is classified as a large aquatic plant that is visible to the naked eye. This category primarily includes vascular plants such as flowering plants (angiosperms) and ferns, along with some non-vascular plants like mosses. They play significant roles in aquatic ecosystems by providing habitat, food, and oxygen for various fish and invertebrate species.

In contrast to microscopic plants or organisms, macrophytes can be crucial indicators of water quality and ecosystem health, as their presence, abundance, and species diversity can reflect the conditions of the aquatic environment. Understanding the role of macrophytes is essential for effective management and conservation of aquatic habitats, especially in the context of herbicide application where control of invasive aquatic plants may be necessary.
