N population size, JPR presence of juveniles, IND number of individuals measured, FLM total number of counted flowers, FRM total number of counted fruits, PS (%) percentage of pollination success, FLN average number of flowers per stem, FLN average number of fruits per stem, SNS average seed number per shoot
^aThis population size for LAKM represents a cluster of a bigger population; the total size is estimated based on the area and field observations
^b“–” = the presence of juveniles in ANTH could not be measured due to dense grass
