    Species with Declining Populations (Marine)

    Quantifies the proportion of marine species whose numbers are currently decreasing. This statistic is essential for understanding the pressures on marine biodiversity and indicates the health of marine ecosystems. A high percentage points to significant challenges such as overfishing, habitat destruction, pollution, and the impacts of climate change on marine environments.

    Monitoring this metric is critical for directing marine conservation strategies effectively. It identifies species in urgent need of conservation action and helps prioritize areas where interventions can have the most significant impact. Strategies to address these declines often include the enforcement of fishing quotas, the establishment of marine protected areas, and restoration projects for critical habitats like coral reefs and mangroves. These measures are crucial for reversing negative trends and ensuring the sustainability and resilience of marine 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 marine species’ extent of occurrence are sourced from the IUCN Red List, and 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.
