Observation on data availability/gaps

Data is not available. The TNFD identifies species metrics, for population size or extinction risk, as being complementary to ecosystem metrics for assessing changes to the state of nature. PDF is part of measurement of species extinction risk. It is a measure of local extinction, presented as the mean change in species richness, relative to a local reference site, within a known area and time frame. PDF is widely used in Life Cycle Assessment
(LCA) as an ecosystem condition metric. Further information on PDF can also be found here: https://www.biodiversity-metrics.org/uploads/1/2/7/5/127509512/bridging_the_gap_between_biodiversity_footprint_and_biodiversity_state_indicator_metrics_2e.pdf
