You may have heard some bad news recently about butterflies. A new report in the journal Science found butterfly populations across the US have plummeted over the last 25 yeas, dropping by 22%. But there are things you can do to help – even if you don’t have a yard.
Jeffrey Glassberg is the founder and president of the North American Butterfly Association, and one of the authors on that paper. Since 1984, he’s been running an annual butterfly count in the region. He says the situation in the New York City region is not good, largely due to a handful of factors, including pesticides, the climate crisis, and habitat loss
He says most people assume if a wild area gets developed, that the butterflies will just move elsewhere. But that's not the case.
"When you build the parking lot and have destroyed that little meadow that was there, the population of butterflies that live in the meadow are now gone from the face of the earth," he said. "So every time you build the parking lot or the houses or the shopping mall, you're decreasing the number of butterflies."
Louise Washer is a co-founder of the nonprofit Pollinator Pathway. She says one way to help is to make sure to buy organic vegetables, so fewer pesticides get used. And help build habitat where butterflies can get food and shelter as they pass through. Even putting just a pot out on a fire escape with a mix of native plants can help.
"You can provide a little way station for butterflies that might be trying to travel across the city," she said. She also recommends that people can volunteer with neighborhood parks and greenspaces, and help push for more native plants and fewer pesticides.
Glassberg said all these little acts add up.
"Will it turn the world around? No. But will it make it maybe a little bit better? Yes," he said. "You know, you can actually do something, make a difference and it will allow you to enjoy the butterflies as well."
Who doesn't want that?
