Zostera marina sp.
Zostera marina, commonly known as eelgrass, is a seagrass species that plays a crucial role in coastal ecosystems.
Common Name: Eelgrass
Scientific Name: Zostera marina
Characteristics: Zostera marina is a submerged aquatic plant with long, ribbon-like leaves. It typically forms dense underwater meadows.
Habitat and Distribution:
Zostera marina is a marine flowering plant that forms extensive underwater meadows in shallow coastal areas. It is found in temperate and subarctic regions of the Northern Hemisphere.
Conservation Status & Threats:
The conservation status of Zostera marina can vary in different regions, but is critically endangered in Portugal according to the EU Red List of Habitats.
Seagrasses, including Zostera marina, face various threats such as habitat destruction due to coastal development, dredging, overfishing, and eutrophication (excessive nutrient input). Climate change and rising sea temperatures can also impact seagrass health.
Ecological Importance:
Eelgrass meadows provide important ecosystem services, including serving as nursery grounds for many fish species and providing habitat for various marine organisms.
They contribute to water quality by stabilising sediments and acting as nutrient sinks.
