Storms in Mexico Kill Millions of Monarchs

While international Efforts are under way to help keep dwindling Populations of monarch butterflies from disappearing, scientists are raising concerns about how severe weather and a loss of forest habitat at their wintering grounds in Mexico are affecting them.Every year, monarchs Embark on an epic multigenerational migration that takes them Thousands of miles from Canada and the U.S. in search of sites in California and in Mexico. The fir trees in the southern regions offer the shelter and warmth they need to survive the winter.Unfortunately, Reviews These vital forests in Mexico have been threatened by illegal logging, and now storms have destroyed Hundreds of acres of habitat, while severe weather is Believed to have killed an estimated 6.2 million of the iconic Reviews These butterflies."Since the forests provide the microclimate needed for butterflies to survive the winter, illegal logging must be eradicated and degraded areas need to be restored," said Omar Vidal, CEO of World Wildlife Fund (WWF) Mexico. "This would help the monarch butterfly to better adapt to extreme climate events, and Also provide local communities with sustainable economic alternatives."According to WWF, while illegal logging is Believed to have declined over the past year Significantly, habitat degradation is still a problem and now climate change is posing another problem.

Reviews These already fragile butterflies face Reviews their high mortality rates along the route from other threats that range from predators and parasites to a loss of habitat along Reviews their migration path. They travel north in the spring in search of milkweed plants - the only plant that monarchs lay eggs on and caterpillars eat. But Reviews These plants are being destroyed by the herbicide glyphosate, the which is sprayed on fields where genetically modified Roundup-ready corn and soy crops are grown.According to the Xerces Society, in the 1990s, an estimated one billion monarchs made this migration, but over the past 15 years, they've lost millions of acres of habitat and the number of monarchs has steadily dropped by 80 percent, or more by some estimates.The good news is that Reviews These butterflies are not without advocates working to help them recover. Individuals are working in their gardens and communities to improve butterfly habitat. Conservation organisasi are working on other measures, Including seeking endangered species status for monarchs and working on habitat restoration.
