Global Report on Migratory Wildlife Health
A new report indicates that 49% of migratory species protected by the UN’s Convention are declining, with 24% facing extinction. The decline in species population has risen by 5% and extinction risk by 2% in the past two years, updating the 2024 State of World’s Migratory Species report.
Species Affected
- Bird Species: Bird flu is contributing to mass mortality.
- Ungulates: Includes species like Wildebeest and Llama.
- Marine Species: Sharks, rays, and turtles are at risk.
- Mongolian Gazelle: Notable decline in mobility from 2002-2021.
Conservation Status Changes
- 26 species have moved to a higher extinction risk category; 18 are migratory shorebirds.
- Improvement noted in species like the Saiga Antelope and Mediterranean Monk Seal.
IUCN Red List and CMS Treaty
The IUCN Red List classifies species based on extinction risk. The CMS is a legally binding treaty since 1979 focusing on conserving migratory animals and their habitats.
Threats Highlighted
- Avian Influenza: H5N1 has caused significant mortality in protected bird species.
- Habitat Threats: Overexploitation, habitat loss, and fragmentation are major threats.
- Infrastructure Impact: Railways, roads, and pipelines threaten migration, especially in Central Asia.
Conclusion
This report emphasizes the urgent need for concerted conservation action. Despite some improvements, many species face increased pressure across their migratory routes.
