The study underscores how habitat loss and other threats along migratory routes contribute significantly to dwindling populations

A new United Nations report released on Monday highlights concerning trends for migratory species worldwide. The report highlights that nearly half of the world’s migratory species are facing declines, attributed to various threats including habitat loss, illegal hunting and fishing, pollution and climate change. According to the report, approximately 44 per cent of migratory species globally are experiencing population decreases, with over a fifth of the nearly 1,200 monitored species at risk of extinction.

The study underscores how habitat loss and other threats along migratory routes contribute significantly to dwindling populations. Drawing upon existing data, including insights from the International Union for Conservation of Nature’s Red List, which assesses the species’ endangered statusthe report provides a comprehensive assessment of the current situation.

During the U.N. meeting, delegates will deliberate on proposals to implement conservation measures, including the potential formal listing of several new species of concern. Notably, representatives from eight South American governments are anticipated to jointly propose the inclusion of two declining Amazon catfish species onto the U.N. treaty’s list of migratory species of concern. The Amazon River basin, the world’s largest freshwater system, is integral to the survival of these species, highlighting the critical importance of habitat preservation.

The urgency for conservation action is underscored by previous commitments made at the 2022 U.N. Biodiversity Conference in Montreal, Canada, where governments pledged to safeguard 30 per cent of the planet’s land and water resources for conservation purposes. As discussions unfold, stakeholders emphasise the need for concerted efforts to protect migratory species and their habitats to mitigate further population declines and safeguard biodiversity.
