as an Output of a zonal-statistics calculation I get points representing the lowest points in each polygon. (the Polygons represent Dolines)

Points

How can i reduce the number of Points per Polygon to one? it doesn't matter which of the Points as they all represent the same value. In the Attribute-table of the Point feature class the ID of the Polygons is already added.
