Mangroves form intertidal forests in which red mangrove prop roots, black mangrove pneumatophores, and their associated peat banks serve as the dominant intertidal substrata for other members of the mangrove community. Black mangroves (Avicennia germinans
) and white mangroves (Laguncularia racemosa
) are usually found in association with red mangroves. Segregation of the 3 species does occur, however; with red mangroves typically occupying the lowest intertidal position. Black and white mangroves occur at slightly higher tidal elevations.
