 The flora and fauna is extremely varied due to the numerous types of habitat, and includes many species that are otherwise rare in the area.Large numbers of bird species are resident or passage migrants here, including many ducks, geese and waders.The wide range of species is mainly due to Brandon Marsh being one of the few extensive areas of water in the area (accounting for such local rarities as osprey and whooper swan) together with the existence of habitats such as reedbed and woodland in close proximity.
