A seagrass meadow or seagrass bed is an underwater ecosystem formed by seagrasses. Seagrasses are marine (saltwater) plants found in shallow coastal waters and in the brackish waters of estuaries . Seagrasses are flowering plants with stems and long green, grass-like leaves.
An additional threat to seagrass beds is the introduction of non-native species. For seagrass beds worldwide, at least 28 non-native species have become established. Of these invasive species, the majority (64%) have been documented to infer negative effects on the ecosystem. [123]
As of 2010 there were 10 seagrass species at high risk of extinction. While three were considered endangered. With seagrass species loss comes biodiversity loss. This paper studies not only human impact on seagrass beds but also global climate change and how changing environments are impacting seagrasses worldwide (Short, Frederick T. et al ...
Editor’s note: This story is part one of a two-part series on the catastrophic seagrass die-offs plaguing nearly all of Florida’s coastal waters. The die-offs persist, raising the question ...
Seagrasses form extensive beds or meadows, which can be either monospecific (made up of one species) or multispecific (where more than one species co-exist). Seagrass beds make highly diverse and productive ecosystems.
Zostera marina is a flowering vascular plant species as one of many kinds of seagrass, with this species known primarily by the English name of eelgrass with seawrack much less used, and refers to the plant after breaking loose from the submerged wetland soil, and drifting free with ocean current and waves to a coast seashore.
A bill co-sponsored by Rep. Toby Overdorf seems well intentioned, but it wouldn't adequately protect fragile seagrass beds from destruction. Marine 'mitigation banks' aren't answer for protecting ...
However, today seagrass meadows are being damaged by human activities such as pollution from land runoff, fishing boats that drag dredges or trawls across the meadows uprooting the grass, and overfishing which unbalances the ecosystem. Seagrass meadows are currently being destroyed at a rate of about two football fields every hour.
