This function plots the species latest six year geometric relative abundance mean status against the relative abundance threshold for each OSPAR region, adding trend arrows corresponding to changes in threshold status between a previous and latest six year geometric means.

latest_breeding_assessment_plot_OSPAR_ALL(
  latest.dat = ByRegion.dat.latest.mean,
  previous.dat = ByRegion.dat.previous.mean
)

Arguments

latest.dat

data frame containing species latest six year geometric mean for each region

change.dat

data frame containing species latest six year yearly percentage relative abundance change

Value

latest breeding assessment plot for each species within each OSPAR region

Details

  • above upper relative abundance threshold of 1.3.

  • above species threshold set by number of eggs species lays (threshold 0.7 or 0.8)

  • below species threshold (threshold 0.7 or 0.8)

  • incomplete information

Different arrows in the plot indicate change in threshold status

  • vertical thick arrow pointing down for change from above upper threshold to below species threshold.

  • vertical thin arrow pointing down for either change from above upper threshold to between threshold or between thresholds to below species threshold.

  • vertical thin arrow pointing up for either change from below species threshold to between thresholds or between thresholds to above upper threshold.

  • vertical thick arrow pointing up for change below threshold to above upper threshold.
