The areas at highest risk were considered to be the habitats of highest conservation importance. These were represented by the Natura 2000 sites, special areas of conservation established under the 1993 EU habitats directive (EEA, 2011), that could be invaded by the common water hyacinth. p. p. vegetation; and (v) constantly flowing Mediterranean rivers with Paspalo– Agrostidion species and hanging curtains of Salix and Populus alba. The area of the Iberian Peninsula at highest risk from the common water hyacinth was identified by overlaying the raster map of the area of potential establishment with a vector map of Natura 2000 sites that are particularly suitable for colonization by common water hyacinth.

Stage 3: Mapping Endangered Areas Before attempting to map an endangered area, it is important to have a clear understanding of economically important loss in terms of the PRA. For producers, as explained above in the section ‘Definitions of critical terms’, economically important loss occurs when the EIL is exceeded. EILs can be expressed in several ways such as the number of pests recorded over a unit of time on traps or the proportion of plants infected with a disease. When the EIL is exceeded for a crop pest, an intervention such as treating the crop with a plant protection product gives greater financial benefits than the cost of the treatment.
