For column 7: Indicate the epidemiological units to be surveyed, indicating its description and unit of measurement. Epidemiological unit is defined as a homogeneous area where the interactions between the pest, the host plants and the abiotic and biotic factors and conditions would result into the same epidemiology, should the pest be present. The epidemiological units are a subdivision of the target population that are homogenous in terms of epidemiology with at least one host plant. In some cases the whole host plant population in a region/area/country might be defined as epidemiological unit. They could be NUTS regions, urban areas, forests, rose gardens or farms, or hectares. The choice shall be justified in the underlying assumptions.
