Last fall, the results of trapping for the European Grapevine Moth (Lobesia botrana or EGVM) in California were recounted during a conference call for the partners working to eradicate this invasive insect: zero, zero, zero, one moth.
We’ve gone from more than 100,000 EGVM trapped in 2010 to just one in 2014. This success makes the EGVM detection and eradication partnership one of the most effective programs for the Animal and Plant Health Inspection Service (APHIS), the California Department of Food and Agriculture (CDFA), county departments of agriculture, University of California Cooperative Extension (UC Coop), and growers in the last decade.

John Eisemann spends much of his time on the phone or in meetings talking to USDA National Wildlife Research Center (NWRC, Center) partners and stakeholders. As the Technology Transfer Program Manager for the Center, John works with private companies, international groups, and non-governmental organizations to encourage the development and licensing of new wildlife damage management products.
The Federal Technology Transfer Act of 1986 changed how Federal Government research and development entities, like NWRC, do business. The Act allows Federal laboratories and industry to form commercial partnerships that enhance the development of new technologies and move them to the marketplace to meet public and consumer needs.

The Raggeds Wilderness, a nearly 65,000-acre area on the Gunnison and White River National Forests near Paonia, Colorado, is prime elk habitat with herd numbers in the hundreds.
Acres of undisturbed coniferous forests are interspersed with open slopes of wet meadows thick with grasses and sedges, a nutritious diet for elk needing to fatten up for the winter. But houndstongue, a purple-flowered invasive weed that takes root alongside nutritious plants, is toxic to elk. Read more »
Alex Vaisvil, a student intern from Xavier University in Cincinnati, Ohio, lowers a Lindgren multi-funnel trap to lure longhorned beetles from the mid-canopy in the Tongass National Forest. Traps were located in the forest as part of a study to refine woodborer trapping methods in Southeast Alaska. (U.S. Forest Service/Elizabeth Graham)
Non-native longhorned beetles are easily transported around the world in solid wood packing material, arriving in a new location with no natural enemies to control their populations. Across the country, many of these non-native beetles, particularly the Asian longhorned beetle, have killed tens of thousands of hardwood trees, especially in eastern states.
Will these pests ravage trees in Southeast Alaska? U.S. Forest Service specialists are working to determine ways to prevent the kind of devastation they’ve had elsewhere. Read more »
While working for the city of Worland for the Wyoming Game & Fish Department, Rory Karhu, currently a NRCS district conservationist in Park County, spearheaded tamarisk removal along the Gooseberry Creek, a tributary to the Big Horn River. NRCS photo.
It took Dee Hillberry six years before he could get a handle on encroaching and hardy invasive vegetation. Working on two separate properties, he removed tamarisk trees, or salt cedars, from 200 acres along Cottonwood Creek and Russian olive trees from 100 acres along the Big Horn River.
Despite Hillberry’s hard work in Hot Springs County, Wyoming, his efforts in restoring riparian areas were part of a larger endeavor that involved work done in phases over several years, over hundreds of miles, and with numerous partners in the Big Horn River basin. The basin is about 100 miles wide, and so far, more than 13,000 acres of invasive trees have been removed from the riparian area. Read more »

Inner city youth helped protect an ancient forest wilderness in the Siuslaw National Forest by spending a day removing invasive tansy ragwort.
High school students from the Inner City Youth Institute in Portland, Oregon, arrived in the Drift Creek Wilderness near the Alsea River, where Douglas fir and western hemlock make up the largest stand of old-growth rainforest in the Oregon Coast Range.
“We love coming to the Siuslaw,” said institute group leader, Stacey Sowders. “We love this chance to do meaningful work and meet people who are so passionate about what they do.” Read more »
