Neochetina feed almost exclusively on the highly vigorous water hyacinth (Eichhornia spp.).
In India, the eagle is also threatened by the spread of water hyacinth (Eichhornia spp.) which spread over lakes and make finding prey difficult.
They preserve various threatened plants of Bourgogne, and also contain a range of tropical and sub-tropical genera such as Psilotum and Lycopodium, tropical aquatics such as Eichhornia and Salvinia, carnivorous plants including Sarracenia and Darlingtonia, and epiphytes including Bromeliaceae and Orchidaceae.
