seagrassmiljöer

Seagrass miljöer, also known as seagrass meadows, are underwater ecosystems formed by flowering plants of the family Cymodoceaceae, Hydrocharitaceae, Posidoniaceae, and Zosteraceae. These plants, which are true marine angiosperms, thrive in shallow, sheltered coastal waters and are found in all oceans of the world, except for the polar regions. Seagrasses typically colonize soft, muddy, or sandy substrates.

These meadows are highly productive and play a crucial role in coastal environments. They provide habitat and nursery grounds for a diverse array of marine life, including fish, crustaceans, mollusks, and sea turtles. The dense root systems of seagrasses stabilize the seabed, reducing erosion and improving water clarity by trapping suspended particles. Their blades also absorb excess nutrients from the water, helping to prevent eutrophication and the proliferation of harmful algal blooms.

Seagrass miljöer are sensitive to environmental changes and are threatened by human activities such as coastal development, dredging, pollution, and unsustainable fishing practices. The loss of these vital habitats can have significant negative impacts on biodiversity, fisheries, and coastal protection. Conservation efforts are underway in many regions to protect and restore these valuable underwater ecosystems.
