Monarch butterfly numbers have been brought
low |
Illegal
logging in Mexico's national parks continues to threaten millions of
butterflies, despite a government crackdown, environmentalists
warn.
Mexico's government has taken drastic measures to protect the
butterflies.
It has formed a team of 17 park rangers, armed with assault
rifles and body armour to protect the colonies of Monarch
butterflies in Michoacan state.
In 2004, numbers of the migrating Monarch butterfly plummeted to
100 million - the lowest ever recorded.
The park rangers are there to help protect the winter nesting
grounds of tens of millions of orange and black winged butterflies
from armed gangs of illegal loggers in the 56,259-hectare Monarch
Butterfly Biosphere Reserve.
Despite facing hefty jail sentences, environmentalists say the
loggers have continued unabated.
"The illegal logging has actually accelerated in the last 4 to 5
years," said Professor Lincoln Brower, a biologist and leading
expert on the Monarch butterfly.
'Ruthless trade'
After several flights over the area, Professor Brower says he's
angered at the vast empty zones, clearly visible from the air.
"I'm just appalled by the failure of the local authorities and
the federal government to cooperate to put these illegal loggers out
of business," he said.

In a country
where kidnappings and car-jackings are run of the mill, the illegal
timber trade is equally ruthless. Gangs are frequently armed and
work at night to avoid detection.
Mexico's environment ministry estimates the country's highland
fir forests have shrunk by half since 1968, despite massive planting
operations.
In 2004, butterfly numbers plummeted to around 100 million, the
lowest ever recorded. This season, WWF says numbers have tripled
this season, but still no where near the numbers - possibly ten
times this - seen in the mid 1990s.
Logging has been the main source of income for many generations,
and while some communities have turned their hand to 'butterfly
tourism', many others feel cheated.
"The environmentalists have pushed the government, but... we have
no other way of making a living," said Homero Gomez, spokesperson
for Rosario, a village which is host to the most monarchs and
tourists each year.
International pressure
But Jose Alvarez, head of the Michoacan Reforestation Fund - a
group which has helped villagers plant more than 480,000 trees this
year alone, says this is a near-sighted argument.
"If this (logging) continues, we won't have any butterflies,
there won't be any water and there won't be any villages, the trees
are the basis for everything that is living in this area," he said.
The
Michoacan Reforestation Fund is working closely with Professor
Brower and scientists from the US space agency (Nasa) on an aerial
reconnaissance programme to try to understand which parts of the
forest are critical for the Monarchs, and where those areas are in
relation to the trends in logging activity.
Professor Brower says these recent reconnaissance flights have
confirmed what has baffled scientists for years: the monarch
butterflies have been journeying 5,000km from Canada and the US, and
returning to exactly the same over-wintering sites in Mexico for the
past 25 years.
He says international pressure is what is needed to help save,
not only the butterflies, but the entire ecosystem.
The Monarch has become a symbol of cross border co-operation with
the US, but some scientists fear it could become a symbol of a
common failure to protect the environment.
