UNEP Reported Nearly Half of Migratory Species Under a Key UN Treaty are in Decline
A Sobering Assessment
In January 2024, the UN Environment Programme (UNEP) released a report showing that nearly half of migratory species under its treaty are in decline, with one in five facing extinction. These include birds, fish, and mammals that cross borders, linking ecosystems worldwide.
Why Migratory Species Matter
Migratory species are ecological connectors. Birds pollinate plants and control pests, fish sustain food chains, and mammals maintain ecosystem balance. Their decline signals systemic stress across habitats.
Drivers of Decline
Habitat loss, overfishing, pollution, and climate change are the main culprits. Infrastructure like dams and roads blocks migration routes, while warming oceans disrupt feeding grounds.
Global Implications
Because migratory species cross borders, conservation requires international cooperation. The report urged nations to strengthen treaties, expand protected areas, and reduce threats like plastic pollution and unsustainable fishing.
Looking Ahead
The report is a wake‑up call. Protecting migratory species is not just about biodiversity—it’s about sustaining ecosystems that humans rely on.
