Each fall, millions of Monarch butterflies migrate south from Canada and north U.S.. Most of them stay in Mexico, some stay in California. Year by year, thousands of butterflies come to the same trees and those famous "butterfly trees" can be found in Santa Cruz, Pacific Grove, and Santa Barbara. (The nearest one is in the Natural Bridge State Park in Santa Cruz.)This morning I read from this month's National Geographic that the Mexican forest where these butterflies stayed the winder was heavily destroyed by logging in the past 4 years. To save it, the UNESCO had made the site a World Heritage this year but we didn't know what impact it had already done. Since my last trip to see the butterflies was ten years ago, I decided it's time to pay a visit again.
I did notice the number of butterflies seemed to be much less than what I saw ten years ago. (Ironically, there seemed to be more people coming to see the butterflies than the butterflies themselves.) Will I still see them ten years later? I don't know.
Note: those butterflies tend to stay high on the tree so make sure you bring a telescope with you.
