In the 1990s, a few hundred million monarchs made the 5,000-kilometre (3,100-mile) journey from breeding sites across the eastern United States and Canada to their overwintering grounds in Mexico.

Their numbers are in decline and now, just tens of millions make this journey. Researchers, conservationists and community scientists are working at both ends of the butterflies’ journey to try to understand the reasons for the decline. Loss of breeding habitats in the USA is one of their research priorities.
