    Species with Declining Populations (Terrestrial)

    Tracks the proportion of land-based species experiencing reductions in population numbers. This indicator is crucial for assessing the resilience and overall health of terrestrial ecosystems, as it underscores the severity of biodiversity loss across different habitats. Elevated values indicate intense environmental stressors, including habitat fragmentation, climate change, invasive species introduction, and overexploitation, all contributing significantly to the downward trends in species populations.

    Monitoring this metric is vital for effectively targeting conservation efforts. It helps identify species that are most at risk and in need of immediate protective measures to halt and reverse population declines. This information drives the creation of focused conservation actions, such as enhancing habitat connectivity, enforcing stricter wildlife protection laws, and promoting sustainable land management practices. These initiatives are fundamental to bolstering the populations of declining species, aiming to restore ecological balance and ensure the preservation of terrestrial biodiversity.

    The higher the score, the better the country ranks for this parameter.

    The table is sorted from the highest score to the lowest:

    Source and Calculation

    Shapefiles of terrestrial species’ extent of occurrence are sourced from the IUCN Red List, BirdLife International, and the Global Assessment of Reptile Distributions Initiative and are used to create country lists of terrestrial species. Global Red List assessments are sourced from the IUCN Red List. A minimum score is given to a country that has 50% or more of its species assessed as declining.

    *Different sources offer varying data, as datasets may be subject to changes due to recent updates and revisions.
