2010 SAF elections. We have reprinted the biographical information and campaign statements of the two candidates for SAF vice-president: Mary J. Coulombe, CF, and H. William Rockwell Jr., CF/FCA, as well as the biographical information and campaign statements of those running for seats on the SAF Council. Page 8. Mapping global forest canopy heights with LIDAR, satellite data. Using National Aeronautic and Space Administration satellite data, scientists have produced a first-of-its-kind map that details the height of the world’s forests. Although there are other local- and regional-scale forest canopy maps, the new map is the first that spans the entire globe and is based on one uniform method. Page 13. Field Tech: Webinars serve as educational resources for foresters and their clients. Webinars, or Web-based seminars. These events offer access to expert talks on a range of topics through video or slide presentations and technology demonstrations, as well as a chance to ask questions of the presenters, in most cases, all through your desktop or laptop computer via a high-speed Internet connection. Some webinars let you earn SAF Continuing Forestry Education credits. Page 14. Here’s how to engage absentee owners and part-time residents in Firewise communities. Carbon County, Pennsylvania, has many second and vacation homes, as well as permanent homeowners who have recently moved to forest and shrub lands. Unfortunately, engaging part-time and seasonal owners about the need for ongoing maintenance of a fire-safe home environment has been a challenge.

On August 5, the Tennessee Department of Agriculture announced the discovery of TCD in that state, in the heart of the range of black walnut. With a mortality rate near 100 percent and no known means of controlling infestations, the prognosis for black walnut is dire. “Based on the patterns seen in the West,” said Whitney Cranshaw, a professor of entomology at the University of Colorado, “such a colonization could very possibly develop into an uncontrollable outbreak. This may ultimately have the potential to destroy black walnut in its native range.” Tests at the University of Tennessee– Knoxville have confirmed the presence of the disease. The state’s Department of Agriculture said it would establish a quarantine in Knox County that prohibits the movement of firewood and black walnut nursery stock and limits the movement of black walnut timber and other material

that can spread TCD. Agency personnel have been surveying the area for more infected trees. A spokesperson said the agency would soon assemble an incident management team to assess the infestation and work to prevent its spread. TCD is caused by a fungus, Geosmithia morbida, which is spread by the
walnut twig beetle (Pityophthorus juglandis), an insect native to the United States that is about 1.5 to 1.9 millimeters long, (See “Walnut” page 3)

FSC Forest Certification in China
By Steve Wilent his summer has been an especially active one for threatened and endangered species—or at least for the courts and the agencies responsible for managing them. In the most prominent case, a federal judge ruled on August 5 that the US Fish and Wildlife Service’s 2009 decision to remove gray wolves in Montana and Idaho, but not Wyoming, from Endangered Species Act (ESA) protection was illegal because it applied to a subset of the species, not the en-
tire species, as required by the act. US District Judge Donald Molloy ruled that “The Endangered Species Act does not allow the US Fish & Wildlife Service (USFWS) to list only part of a ‘species’ as endangered, or to protect a listed distinct population segment only in part.... [The act] does not allow a distinct population segment to be subdivided.” The case before Molloy was brought by (See “Species” page 4)

By Ke Dong hina’s economy is growing at a dramatic rate and in the process the country is positioning itself as “the manufacturer of the world,” which is calling for increasing amounts of energy and resources. A greater demand for Forest Stewardship Council (FSC) certified wood products in recent years is driving many Chinese companies to apply for FSC forest certification. Thus, FSC certification is growing quickly in China. Since February 2002, when the first forest in China, Zhejiang Changhua Forest Farm, received its FSC certificate, there have been 44 management units with 1.35 million hectares of forest receiving FSC Forest Management (FM) certificates (through May 2010). Of the 44 certificates in China, one has expired and one was for a FSC demonstration forest near Beijing that does not have commercial timber harvesting. Although interest in FSC certification in China has dramatically increased, significant challenges abound. Meeting FSC’s so(See “China” page 5)
