latest_proportion_wintering_species_above_threshold.Rd
This function calculates the proportion of wintering species within a functional group and OSPAR region, whose latest six year relative abundance mean is above the threshold for that species. The threshold is 0.7 for species laying more than one egg and 0.8 for species laying one egg.
