Research Examines Barriers to Grazing for National Forest Management

Targeted grazing – using livestock to intentionally manage vegetation – can excel at treating large patches of edible invasive plants and can also create fuel breaks to reduce wildfire risk. So why don’t U.S. Forest Service staff use it more often to manage national forests? That’s the question Briana Swette, a postdoctoral fellow working with Dr. Kelly Hopping at Boise State University, wanted to answer.

Wyoming Imagines a Future with Invasive Annual Grasses Under Control

In science fiction, the silent-invasion plot is well worn. An alien species slowly takes over its target land, stealthily replacing the native population until the invasion is complete. In the movies, a plucky band of scientists and citizens grow wise to the threat and fight back, but it’s often too late. It’s not science fiction when it’s actually happening, as it is Wyoming. The invaders there are invasive annual grasses like cheatgrass, medusahead and ventenata – but the scientists and citizens are fighting back.

Plant Risk Evaluator Tool Helps Identify Potentially Problematic Plants

The easiest pest to manage is the one that’s not there. That’s why prevention and avoidance are first two principles of integrated pest management’s “PAMS Approach,” with monitoring and suppression following behind. It’s also the rationale behind the Plant Risk Evaluator Tool, an online database to evaluate the potential for ornamental and horticultural plants to become invasive weeds in different areas and environments.

Exploring a Fiery Method for Replacing Invasive Grasses

In California and throughout the West, land managers face huge challenges on huge acreage. Threats include invasive annual grasses, drier summers and changing fire regimes. To combat this combined threat, UC Davis researchers are testing a burn-and-replant method as a combined solution.

Work Group Aims to Make New Endangered Species Rules Workable

“If it’s so complex that it’s impossible, then no one wins.”

That was the key takeaway from a recent two-day workshop in Vancouver, Washington about implementing new U.S. Environmental Protection Agency pesticide-use rules to protect endangered and threatened species.

Managing Correctional Facility Mosquitoes Now, Acquiring Skills for Later

There have always been mosquitoes in the wetlands northwest of Salt Lake City, Utah, but few human until the opening of the Utah State Correctional Facility brought more than 4,000 new warm bodies to the area for the mosquitoes to feed on. Now, with Western IPM Center support, efforts are under way to control the mosquitoes and train inmates for jobs in vector control.

Understanding Hawaii’s Ungulate Issues

Hooved mammals – ungulates in scientific parlance – aren’t native to the archipelago but have been brought to the islands over the past centuries. Now, population explosions of wild pigs, feral sheep and goats, big-horned mouflon sheep and axis and black-tailed deer are altering ecosystems, affecting fisheries, imperiling agriculture and causing economic harm. New research aims to document how much damage those non-native ungulates are doing – the first step in understanding what could or should be done about it.

Chasing Knotweed on One River: 20 Years of Lessons Learned

Forks, Washington’s sits nestled in North America’s only temperate rainforest. Nearby rivers, fed by melting glaciers high in the Olympic mountains, are home to five species of wild salmon and hundreds of other species of native wildlife. But, like too many other landscapes in too many other places, Forks is threatened by non-native, invasive plants that can fundamentally alter the ecosystem at the expense of the region’s native plants and animals.

Hoping a Tiny Wasp Has a Huge Impact in Controlling Spotted Wing Drosophilia

As South Korean imports go, Ganaspis brasiliensis will never have the popular cachet of pop sensations BTS or TV dramas like Squid Game, but for small fruit growers the tiny wasp might become the biggest superstar of all. That’s because Ganaspis brasiliensis is a parasitic wasp that lays eggs into the larvae of the spotted-wing drosophila fruit fly, an invasive insect that’s been plaguing growers of small fruit and berries since it was accidentally introduced into the mainland United States in 2008.

A Humble Hedgerow Serves Pollinators and Beneficial Insects

In an expansive field of organically grown blueberries at Humbug Farms in Independence, Oregon, the most interesting rows aren’t blueberries at all. Instead, they are carefully chosen rows of (mostly) native flowering shrubs that provide food for wild bees and habitat for beneficial insects. Hurray for the humble hedgerow.

Targeted Grazing Can Reduce Communities’ Vulnerability to Wildfire

With the West in a state of permanent drought and under constant threat of wildfires, it’s more important than ever for land managers to control undesirable vegetation. For fire-prone communities scattered throughout the West’s tinder-dry hills and woods, it can be a matter of life and death. One tool that can help manage vegetation is grazing.

During wildfires, crew use bulldozers to cut firebreaks to remove vegetation and prevent the fire from spreading. It’s effective firefighting, but those bulldozer lines can have lasting impacts on the recovery of vegetation afterward. This video examines new research that is measuring those impacts and developing mitigations.

Grassland Restoration Effects on Native Bees and Spiders

Throughout the West, many native grasslands have been degraded – overgrazed, overtilled, burned or overrun by invasive weeds like Medusahead or cheatgrass. While many restoration efforts only look at plant communities or endangered species, this research looked at native spider and bee communities.

Nevada’s state flag has the words “Battle Born” above a silver star and crossed sagebrush sprays, celebrating its creation during the American Civil War. Battle born is also a pretty good description of the efforts of many people working for state, federal and local agencies to keep invasive weeds in check in Nevada’s challenging landscapes. Here’s a look.

Decoding Chemical Communications to Control Insects

University of California, Riverside chemical ecologist Jocelyn Millar identifies the chemical signals insects use to communicate, then synthesizes versions of them to help monitor, trap or disrupt their activities. Lygus bug is just one of dozens of species Millar and his team are working on. The common thread is that they all communicate chemically, and decoding those chemical signals can create new ways to control those species where they are pests.

Alaska In Photos: America’s Arctic Agriculture

Alaska is huge, remote and still largely pristine. It’s 2.3 times the size of Texas, with a population of just 738,000 people and 175,000 moose. While small, the state’s ag industry is important. Ornamentals, aquaculture, potatoes and cattle are top crops, and home-based and small-scale production help improve food security. Here’s a little of what we saw and learned on a recent visit.

Utah in Photos: Managing Pests in a Unique State

Utah is one of the most urbanized states in the nation, with 90 percent of the population living on just 1.1 percent of the land. It’s also the second driest state, averaging less than 10 inches of rainfall a year, and has alkaline soils with low organic matter. It’s a challenging environment to farm in. Keeping invasive pests out of Utah – and minimizing the damage they cause once they arrive – is a major focus.

New Mexico in Photos: Loving the Land of Enchantment

In New Mexico, the chile pepper is king. Hay is grown on 40 times the acreage and pecans rack up nearly 4.5 times the farm sales, but you don’t see either of those crops on the “Welcome to New Mexico” signs as you drive into the state. You see red and green chile peppers. Chile isn’t a crop, it’s culture. Like Florida citrus and Idaho potatoes, New Mexico’s identity is tied to a crop.

Hill-Climbing Cows May Bring Big Benefits to Western Rangeland and Ranchers

Conventional wisdom says cows don’t go up steep slopes. They don’t climb hills and don’t travel very far from water. But some cows never got that memo, and researchers are looking into whether naturally hill-climbing cows can provide production and environmental benefits in the rugged West.

Colorado Battling Emerald Ash Borer with Coordination and Cooperation

In Boulder, Colorado, Assistant Forester Kendra Nash was marking a dead tree for removal, when her spray-painted “X” crossed a D-shaped exit hole characteristic of the insect. The September 2013 discovery was the first in Colorado of the invasive beetle that’s killed tens of millions of trees since first being detected in Michigan in 2002. Here’s what’s happened since.

A section of the front page of a brochure titled "Early Detection and Rapid Response (EDRR) for New Plant Invaders."

Early Detection Combats Weed Invaders

Managing invasive weeds is a lot like planning a military defense. It’s easier to defeat a small number of invaders than a large army. It’s easier to respond to a limited incursion than fight a multi-front battle. And having an early warning system can make all the difference. In the fight against invasive weeds in Montana, early detection and rapid response is a key strategy for keeping some of the West’s worst weeds from gaining a foothold in the state.
