An unknown pest is killing the casuarina trees (Casuarina equisetifolia), also known as Australian pines, that have long beautified the streets and avenues of the Guatemalan capital. At least 600 trees, of the 5,000 found throughout the city, are infected by what is presumed to be a species of pine weevil, says Evelyn Reyna, director of the Guatemala City municipal environment department.

In addition to cutting down the diseased trees, the authorities will begin an urban reforestation plan, which involves planting 35,000 trees of various species.
