Cryptocoryne usteriana

The habitats and sites where this species occurs are threatened by factors which affect all plants occurring in flowing water bodies in the region, notably forest clearance, urbanisation, agricultural intensification and the secondary effects of these factors, particularly increased turbidity, pollution and casual habitat degradation. In particular, two of the sites where this species occurs involve remnant semi-natural habitat between agricultural fields which is very vulnerable to clearance. The species is probably at risk of over-collection.

There are no conservation actions in place specifically for this species and it is not known from any protected areas. There is an urgent need to survey all known populations to derive an up-to-date assessment of the conservation status of known subpopulations, and to confirm the identity of records from adjacent islands.
