"In 1875, trillions of Rocky Mountain locusts gathered and began migrating
across the western United States in search of food. The enormous swarm covered
an area larger than California. Three decades later, these grasshoppers were
extinct.
This fate is all too common for migratory species. Their journeys can make them
especially vulnerable to hunting or fishing. They may move between countries,
meaning protecting the species in one jurisdiction isn’t enough. And it’s hard
for us to even know if they’re in trouble.
Today, we get a global glimpse of how migratory species are faring, in the
first-ever stocktake produced by the United Nations Convention on the
Conservation of Migratory Species. The report shows falling populations in
close to half (44%) the 1,189 species tracked by the convention. The problem is
much worse underwater – 90% of migratory fish species are threatened with
extinction.
Their decline is not inevitable. After all, the migratory humpback whale was
headed for rapid extinction – until we stopped whaling."
