We know underwater animals can cover huge distances across the sea. New research reveals underwater plants are no exception.
Research led by Edith Cowan University found sea grass can ‘hitchhike’ across the sea for hundreds or even thousands of kilometres. This means that damaged or lost habitats can be repopulated from other areas. The research found sea grass move on the surface of the ocean via currents, in the water column along with sediments on the sea floor by growing like a lawn and expanding over time or through consumption and transport by animals.
Re-vegetation and propagation are especially important to safeguard habitats against the effects of climate change. Lead researcher Dr. Kathryn McMahon says the spread of sea grass through seeds is the most promising way to repair damaged habitats but further research and investigation is required.
