"We are witnessing a massive environmental catastrophe" in southern Chile, Accion Ecologica chief Luis Mariano Rendon told AFP yesterday from Mexico.
"There have been whole species lost, such as the Araucaria araucana (monkey puzzle tree). They are trees that take hundreds of years to reach maturity. So this is a practically irreparable loss for current generations."
The trees, a distant relative of better known pine, are considered sacred by indigenous Mapuche people.
Fires in the country's south have ravaged more than 9,100 acres of forest, and have been contained but not put out entirely, firefighters said.
There are still 25 active fires, potentially threatening Conguillio National Park.
