Ecologists are all for it: “For us, the monarch is a convener, it gets people talking about conservation,” Lewis says. “If you can get people to care about monarch conservation and habitat, you will be helping a whole suite of other pollinators too.” And as conservationists in Mexico, the U.S. and Canada scramble to find solutions for the pollinators, finding ways to increase habitat is paramount — scientists say the butterflies need an additional 1.8 billion stems of milkweed on the ground in the U.S. to reach a goal of a monarch population of 225 million by 2020.
