rehevöityä

Rehevöityä is a Finnish verb that describes a process of becoming overgrown, luxuriant, or eutrophic. It is often used in ecological contexts to refer to the enrichment of a body of water with nutrients, leading to excessive growth of algae and aquatic plants. This can result in decreased oxygen levels, which negatively impacts fish and other aquatic life. The term can also be applied to terrestrial environments, where it might describe an area of land becoming excessively fertile and densely vegetated. The underlying concept is one of increased biological productivity and density, often due to an influx of nutrients or favorable growing conditions. When a body of water is described as "rehevöitynyt," it suggests it has undergone this process of becoming overly rich and productive, potentially leading to a decline in biodiversity or water quality. The opposite of revehityä is often described as a state of being oligotrophic or nutrient-poor.
