The International Union for Conservation of Nature added the migratory monarch to its 'red list' for the first time.
endemic to North America has been categorized as an endangered species by the International Union for Conservation of Nature.The monarch's native population has shrunk between 22% and 72% over the past decade. Its decline is largely due to climate change, deforestation and pesticide use, which kills the milkweed the monarchs feed on, the IUCN said Thursday after adding the butterfly to its "red list" of threatened species for the first time.
Eastern monarchs sometimes travel more than 3,000 miles, heading north to places in the U.S. and Canada for the summer and south to Mexico for the winter. Western monarch often fly shorter distances and overwinter in California.The western monarch is at the greatest risk of extinction, the IUCN said, with its population declining from as many as 10 million in the 1980s to less than 2,000 last year.
“It is difficult to watch monarch butterflies and their extraordinary migration teeter on the edge of collapse, but there are signs of hope," said Anna Walker, a member of the IUCN SSC Butterfly and Moth Specialist Group.From planting native milkweed and reducing pesticide use to supporting the protection of overwintering sites and contributing to community science, we all have a role to play in making sure this iconic insect makes a full recovery,” Walker added in a statement.
