Avicennia marina
Grey Mangrove
The Avicennia marina, or Grey Mangrove, is a hardy evergreen tree or shrub known for its adaptability to coastal and saline environments. It grows up to 10 metres tall, featuring leathery, grey-green leaves and small, fragrant white flowers. The Grey Mangrove is distinguished by its pneumatophores-vertical root structures that extend above waterlogged soils, aiding in oxygen intake. Its adaptability makes it a cornerstone of coastal ecosystems, providing erosion control and habitat for marine life.
Native to mangrove forests across Africa, Asia, and Australasia, this versatile species is crucial for stabilising shorelines and supporting biodiversity.
