On this episode we hear from Mongabay's Mexico City-based contributor Martha Pskowski who recently traveled to central Mexico during the winter 'high season' when tourists flock to see monarch butterflies covering the trees. Her fascinating report on threats to monarchs in these overwintering grounds was tempered by cheerful news that the number of monarchs wintering in Mexico is up 144% in 2019. Pskowski spoke with locals who rely on monarch tourism for their livelihoods, and she investigated impacts on the monarchs' habitat from agriculture and a proposed mine.
