In the last decade, the population of butterflies has diminished in the colonies of hibernation in Mexico, so I want to know which are the impacts of the deforestation and what other consequences can have.
I found this:
"Overwintering monarchs need forests for protection from the elements, and they need very specific forests at that. The population that breeds east of the Rocky Mountains migrates to mountains in central Mexico, where they can roost in dense stands of oyamel fir trees. Unfortunately, those trees are a valuable resource, and even after the monarch wintering site was designated as a preserve, logging activities continued illegally. In the 20 years from 1986 to 2006, an estimated 10,500 hectares of forest were either lost entirely, or disturbed to a degree that they no longer provided suitable winter cover for the butterflies. Since 2006, the Mexican government has been more vigilant in enforcing the logging ban within the preserve, and thankfully, deforestation has decreased significantly in recent years".
And:
"The number of migrating monarchs is plummeting for a few reasons: widespread loss of a plant called milkweed, which their young rely on for food; extreme climate fluctuations in North America, including freezing temperatures and heavy rain; and deforestation".
I hope this helps :-)
