Estimated from habitat loss (LUH2) and the genetic-diversity–area relationship of species with range data. A model-based estimate relevant to the genetic-diversity clause of GBF Goal A and to Target 4. How we got this.
Fill: median (q50) of the joint Monte-Carlo distribution at the selected keys. Hatched: confidence low. Dotted: no estimate in this run.
Both metrics drawn; the selected one is emphasised. Line = median (q50); band = q05–q95 over z draws and species bootstrap (joint Monte Carlo at the years shown).
Dot = median (q50); line = q05–q95; grey bar behind = share of the country's land.
RESOLVE 2017 biomes, labelled “GET-equivalent approximation”. Strata under 5 species show no number.
Same encoding. ▨ = confidence low.
Taxon-specific exponents are not used: the prior is one distribution per metric and marker domain.
(APA/At)z, diversity-weighted. The 30 % line is the Target 3 area target, shown for orientation only; this bar is not a 3.1 value. Black tick = share of land area protected. A habitat-fraction transform: it does not mean diversity is maintained inside reserves — drift continues there.
Population decline → diversity through the same power law. Each stratum has its own species set, n and confidence.
The area lens and this lens estimate the same latent quantity by different routes; their disagreement is a diagnostic, not an error bar.
Each row is a species_country_loss record with its prov_id. Expand (▸) draws the species' own curve and the formula with its numbers substituted. Species without a Red List name show their species_id.
Only countries with rows in this run can be added. Values are not an ordering of countries; coverage and priors differ.
Direct labels at line end; bands hidden when more than three countries are shown.
Countries without rows in this run appear greyed in the table, not on the chart.
Rows for the selected country at the selected keys, in the column order of the national-report indicator table. The indicator is placed under “component, complementary or other national indicators”, never under “headline”. Copy as TSV for consideration as an additional national indicator (decision 15/5, annex I, paragraph 1(e)); use in a national report presupposes validation through national mechanisms (annex I, paragraph 3), which this estimate has not had.
