Monarch butterflies are in decline largely because of habitat degradation, including in the Monarch Butterfly Biosphere Reserve in the forested mountains of Central Mexico.
Researchers looked at aerial and satellite photography of forest cover in the Reserve over 50 years, assessing the impact of the Reserve’s protective decrees on logging.
They found that implementation of logging bans worked well when the local community was consulted and compensated, and poorly when done without their involvement.
