资源简介：
As part of the annual partridge spring counts in Flanders, hunters are required to count partridges in all areas that have suitable habitat for partridges (<em>Perdix perdix</em>). Since it is assumed that visibility is around 200 meters, this hexagonal grid with a distance of 400 meters between parallel sides, helps volunteers in choosing observation points.
