Express PRA for Hygrophila polysperma
The results of this PRA show that Hygrophila polysperma poses a low risk to the endangered area under current climatic projections (very small areas of Turkey, Greece and Algeria are marginally suitable along the Mediterranean coastline) with a moderate uncertainty. Hygrophila polysperma is not naturalised in any natural environment within the EPPO region. The Expert Working Group does not recommend any phytosanitary measures for this species.
The Expert Working Group recommends that the PRA is reviewed every ten years and/or when significant new information (e.g. naturalisation in natural environment of the endangered area or ecological data) becomes available.
