Let the invasions begin

As Beijing prepared to welcome athletes and spectators to the Olympic Games, a quieter and much less welcome influx was already under way.

According to a new study by Washington State University ecologist Richard Mack and four Chinese colleagues, China’s explosive economic growth and ambitious public-works projects have allowed non-native species of plants, insects, and other organisms to spread throughout the country and inflict more than $14 billion of damage on the nation’s economy—and the Olympic Games could provide an opportunity for even more biological invaders.

Mack and his co-authors combed through trade and economic data to discover that China’s economic boom has been … » More …

Flames in Our Forest: Disaster or Renewal?

Forest fires have been much in the news. Beginning with the Yellowstone fires in 1988, the West has lived through a series of intense fire years. In 2000, the federal government spent nearly $1.6 billion fighting fires. But over the same period there has been a discordant message: fires, we are told, shaped the forests and the wildlife that inhabit them; fires are, in fact, necessary to the continued existence of many species of plants and animals. Smokey the Bear’s message of fire’s destructive nature, his plea on behalf of other woodland creatures that “fires destroy more than trees,” has lost its venerable certainty.

Mimicking Nature's Fire: Restoring Fire-Prone Forests in the West

Forest health has been much in the news. It is a powerful metaphor—but one of uncertain and ambiguous content. Congress has used it to avoid environmental assessments of logging; opponents of logging have often portrayed it as a smokescreen. Mimicking Nature’s Fire is in part a guide to this debate. Stephen Arno (’65 For.), a forest ecologist, and Carl E. Fiedler, a silviculturist, have combined their talents to argue for “restoration forestry,” an approach that seeks to reestablish “an approximation of historical structure and ecological processes to tree communities that were in the past shaped by distinctive patterns of fire.” The book is divided into … » More …

It came from outer space

The dust on your mantelpiece may be more interesting than it appears at first swipe. Some of it may be from outer space. While that may not make much difference to your dust rag, some feel that extraterrestrial dust might help explain the cyclical nature of the Earth’s climate, says Ed Brook, assistant professor of geology and environmental science at Washington State University’s Vancouver campus.

Brook and his collaborators have developed a method to measure the extraterrestrial dust found in the ice cores taken at Vostok, Antarctica. It involves filtering the dust out of the ice core, a process that takes four days per sample, … » More …
