Deforestation is down in the Mexican forest that is the winter home of the Monarch butterfly, and scientists also hope to see a rebound in the annual migration after it fell to historic lows last year, an expert said Thursday.
Omar Vidal of the World Wildlife Fund said two to three times more Monarchs may arrive this year, compared to last year.
"The data from the United States indicates a light recovery," Vidal said. "They are calculating that we can expect at least double the number and perhaps triple."
Last year, the Monarch population dropped to the lowest level since . . .
