In the aquatic environment, Azolla
Herbaceous genera are characteristic of non-forested swamps; among them are Hydrocotyle (Apiaceae), Pistia (Araceae), Eichornia (Pontederiaceae) and Azolla
(Salviniaceae) (Kalliola et al, 1991; Richards, 1996).
Rothfels' project is to understand the symbiotic relationship between aquatic ferns of the genus Azolla
and the microbiome housed within the chambers of its leaves, which provides the fern with extraordinary nitrogen-fixation abilities and the ability to remediate water contaminated with high concentrations of heavy metals and other toxins.
At present, almost all sheltered open-water areas in the south-eastern and eastern basins are covered with a dense floating mat of Azolla
, which has penetrated also deep into the Phragmites stands.
is a voracious grower and, if left unchecked, could cover the surface of the canal with a thick mat, reducing light and oxygen levels in the water and causing problems for boats and anglers.
Pryer launched a six-week campaign last month to raise $15,000 to decipher the DNA of a fast-growing aquatic fern called azolla
If you are buying plants for your pond, make sure to avoid the five following non-native invasive species that since April 6 this year are now banned: Azolla
filiculoides (water fern); Myriophyllum aquaticum (Parrot's fern); Hydrocotyle ranunculoides (floating pennywort); Ludwigia grandiflora (water primrose); Crassula helmsii (New Zealand pygmyweed).

Similarly the capacity of vascular aquatic plants to assimilate nutrients from polluted waters is well recognized viz, duckweed and Azolla
offer potential alternatives for treating sewage.
, an aquatic fern, which when added to cow fodder increases milk yields and using worms to make compost to fertilize crops, are a huge hit.
Radulovich and his colleagues also see potential in aquatic plants such as azolla
, water hyacinth and alligator weed.
