Abstract

This technical guidance offers the data specification to assess the pro rata value for the eligibility of permanent grassland with scattered ineligible features. It involves a systematic approach to be used during LPIS creation and upkeep processes and a sporadic approach to be used in absence of delineation instruments. The systematic approach involves delineating permanent grassland land cover classes with a known and reliable distribution of their scattered ineligible features. For each land cover class, the pro rata category is precisely determined and with it, the class’ eligibility rate. The reference area for all reference parcels with such land cover class is calculated by summing up all the contributing land cover classes inside their perimeter. The sporadic approach assesses the grassland percentage directly on a (reference or agricultural) parcel. The result is reclassified into one of the two pro rata categories and used ot calculate the maximum eligible area. Both approaches require a reliable and precise assessment of the profusion of grass and herbaceous fodder. This inevitably must be customized to meet the local needs and conditions and both the assessment method and its individual application must be documented.
