Seagrasses are globally important ecosystems, but their extent is decreasing due to human activities and climate change. The condition of intertidal seagrasses on Efate Island in Vanuatu is complex, with seagrasses near Port Vila facing more challenges due to higher levels of nitrogen and suspended solid content in the water.
Seagrasses are globally important, but their extent is decreasing due to the impact of human activities and changing climatic conditions. Seagrass meadows provide vital services, but their condition and distribution are not yet well known, particularly in many small tropical Pacific islands. In 2018, observations and samples were collected from intertidal seagrasses of Efate Island, Vanuatu (South Pacific). Observations included canopy height, percentage cover, growth rate and species variety. Water quality samples were also collected in some locations. Our seagrass metrics suggested more challenging conditions for the seagrasses near Port Vila, the main urban area in the island, where water quality analyses indicated higher levels of dissolved inorganic nitrogen and suspended solids.
