Illegal Loggers Cut Into Core Of Mexico's Forest Preserves For Monarch Butterflies - NYT

[hatrack]

Illegal loggers have chopped their way deep into unique forest reserves in a mountain range in central Mexico where millions of monarch butterflies from eastern North America roost for the winter, according to researchers who posted satellite photographs of the area on a NASA Web site Wednesday evening.

Forests of oyamel fir trees in Michoacán and Mexico States have for thousands of years been a winter haven for the resplendent orange and black butterflies, the most famous “charismatic megafauna” of the insect world, said Lincoln P. Brower, a professor emeritus of biology at Sweet Briar College in Virginia, who has studied the butterflies and their shrinking winter habitat for decades.

The images, posted online at earthobservatory.nasa.gov, show fresh clear-cutting in an area that held large butterfly colonies last year, as seen in aerial surveys, said Daniel Slayback, a geographer based at the NASA Goddard Space Flight Center in Greenbelt, Md., who has been tracking the butterfly wintering grounds with Dr. Brower. The images were taken by the commercial Ikonos satellite for the Monarch Butterfly Sanctuary Foundation, a group with which Dr. Brower is associated.

“There are a number of sawmills around the area that are busy eating away at the forest,” Dr. Slayback said. “These are organized groups that go in armed sometimes. This is wholesale clear-cutting.” The photographs show that cutting is taking place inside a protected “core zone” established by presidential decree in November 2000, according to the NASA Web page.

1. Mexico needs help against these profiteering goons

I was down there last summer and had a long visit with our Mayan guide. A bunch of the Maya have appealed to Greenpeace to get help publicizing the fact that the oil bidness is zeroed in on the area of the Yucatan where the underground rivers run and are accessible via the cenotes. The Maya don't want the oil companies polluting the cenotes.

3. Damn, I knew this would happen sooner or later. One vulnerable habitat ...

is all it takes to wipe out a species.

People always say something like "why don't the butterflies go someplace else?", not knowing -- or not caring -- that the butterflies are following instincts evolved millenia ago, and not likely to change on a time scale of less than decades, if not longer. Species can adapt to habitat changes over time, but not if it is too abrupt, like clear-cutting.
