Monarch Butterflies In Peril
Once common throughout North America, monarch butterflies now face extinction due to pesticide use, climate change, sprawl, and logging in their habitat.
Monarchs are divided into two populations separated by the Rocky Mountains: eastern and western. A few weeks ago the yearly count of eastern monarch butterflies, which spend the winter in Mexico, revealed a more than 80% decline over the past two decades.
In recent years the western population of monarchs has suffered an almost total collapse, with fewer than 2,000 of them counted this winter. A new study published in Science named climate change as the main cause of widespread butterfly declines across the western United States.
This is why the Center is fighting for Endangered Species Act protection for monarchs. And why, this week, we and more than 80 other groups called on Congress to provide $100 million yearly to conserve them.
