Whenever I reveal the purpose of my Mexican excursion, to see these overwintering sites, the reaction is generally a baffled “But…Why?” Yes, this may seem like the kind of trip only an entomologist or true nature-nerd could enjoy, but I can promise you that is not the case. Rather, seeing these butterflies in their innumerous masses was one of the most surreal, incredible, and awe-inspiring sights I have ever seen, or ever will see, and I’m willing to bet that would go for just about anyone who laid eyes on them, regardless of interests, background, age, whatever.

Although the forest itself is beautiful, the trek along the winding dirt paths between the towering trees began with disappointment. After a difficult trip just to get to the preserve, we had walked for what seemed like miles without seeing a single butterfly. However, finally, we stumbled across a bittersweet sign of hope laying dead in the path in front of us, a single Monarch Butterfly. Spirits suddenly lifted, we pressed onwards, only to find another dead Monarch, then two more, then ten more, then hundreds more. Suddenly, we saw them, gathered in huge, brown, motionless masses, clinging to the trees so densely you couldn’t see the bark or the pine needles, their numbers so great they bent and even snapped branches as thick as my arm. It reminded me of the way snow bends and breaks tree limbs after a huge snow storm.

As the morning sun began to break through the trees and fall upon the roosting masses, the Monarchs, one by one, opened their wings to the warmth, until, eventually, the tree branches had erupted into bright orange, pulsating carpets of butterflies. They enveloped the trees, filled the sky, and covered the ground. They ran into our faces and landed on our hands. Their numbers were so vast, we could even hear their delicate wings beating all around us. It was truly indescribable, an experience I will never forget for as long as I live. I really can’t do it justice here.

Unfortunately, this natural miracle is considered what is known as an endangered phenomenon, because the trees in the El Rosario Butterfly Preserve and surrounding areas are threatened by illegal logging. Angangueo is a town stricken with poverty and, for some residents, logging is the only means of satisfactory income. Thanks to the establishment of a preserve, logging is also illegal, but it hasn’t stopped the loggers who, willing to do whatever it takes to support their families, do most of their work at night and are frequently armed. Even though government-appointed guards patrol the forests with guns and bulletproof vests, protecting the trees has become a dangerous and difficult business.

A tree is completely covered by Monarch Butterflies, its limbs bending under their weight. Yes, those are all butterflies.

Fortunately, we don’t need to don vigilante masks and stalk the Mexican forests for gun-toting tree poachers in order to help save the Monarch migration. How do we help? Go see it!Tourism can be a major source of income for the residents of Angangeuo, and the more money we can pump into the town through tourism, the less the residents will have to depend on logging, and the more they will make an effort to protect the Monarchs on their own. If you go, you’ll not only help preserve the migration, you’ll also get to see one of the most incredible things you’ll ever see in your life. It’s freaking awesome, I promise you.

If you do eventually make your way to the butterflies, however, be sure to stay on the designated paths to reduce habitat wear and tear.

Anyway, my research brought me to Conservation International, a nonprofit organization that focuses on preserving earth’s biodiversity and natural heritage. Through innovation, campaigning, and business-like functionality and effectiveness, Conservation International aims to save species, conserve habitats, empower local communities with education, and raise awareness. They hope to demonstrate that human societies can and must live harmoniously with nature, and they help faciliate the construction of this relationship on both a local and global scale.

Of the organizations I saw, Conservation International was one of the most impressive and, it seems, effective. It’s also very cool, in terms of what they do, their website, the information they offer, the way they campaign, etc. I recommend browsing the website a bit and seeing what it’s all about. If you like what you see, or perhaps you’re just feeling particularly inspired by the approach of Earth Day (and I hope you are…), there are a number of ways to support the cause. If you’re interested in preserving tropical forests (and you should be, considering the burning of forests accounts for 20% of the world’s carbon emissions and releases more carbon than all cars, trucks, and planes, combined) , which is central to Conservation International’s conservation strategy, consider donating to the Protect an Acre campaign. This campaign gives you the opportunity to donate $15 to buy an acre of tropical forest, protecting the forest, the life it contains, and the people it supports. If you donate, you’ll even get a little recognition on the website, your name attached to a specific acre on a virtual forest grid. I’ve “bought” my acres. Consider helping out and doing the same.
