Natural Areas

Here are some of the IPM projects, innovations and research benefitting natural areas in the West. Projects listed here are not necessarily funded by the Western IPM Center.

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.



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.



Montana in Photos: Defending the Last Best Place

The state that calls itself "The Last Best Place" has a lot to protect from pests: vast fields of wheat and barley driving its agriculture sector, miles of mountains, forests and rangeland forming an outdoor paradise, and clear rivers and lakes at the upper end of the North American watershed. Here's a look.



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.



Alaska In Photos: America's Arctic Agriculture

Alaska is huge, diverse, 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 and diversity. Here's a little of what we saw and learned on a recent visit.



VIDEO: Learning about Insects in Anchorage

Anchorage-area sixth graders learn about forest insect ecology during the 43rd annual Outdoor Week at the Bureau of Land Management's Campbell Creek Science Center.



VIDEO: Controlling Invasive Species on Wyoming's Snake River

The Teton County Weed & Pest District's Snake River Project helps keep invasive weeds from getting established in the Snake River corridor in western Wyoming. Here's a look at one part of that effort. 



VIDEO: Battling Bird Cherry in Anchorage

European bird cherry, also known as the May Day tree, is one of the most pervasive invasive species in Anchorage, Alaska. Here's how it got there, and what folks are now doing to get rid of it.



VIDEO: Biocontrol on Montana's National Bison Range

Biocontrol helps the National Bison Range in Montana manage invasive weeds. Here's how they do it - and you can too.



VIDEO: Gold Spotted Oak Borer, or GSOB, in Irvine Regional Park

Weir Canyon in the Irvine Regional Park is the only known infestation of gold spotted oak borer in Orange County - and land managers are working hard to protect the park and keep the destructive beetle from spreading.



VIDEO: Gold Spotted Oak Borer, or GSOB, in Southern California

The gold spotted oak borer is a tiny beetle causing huge damage in Southern California. It infests the region's towering oak species - coast live oak and canyon live oak - and can kill a centuries-old tree in just a year or two.

This video follows the beetle from San Diego to Los Angeles counties to see what damage it's doing and what many fear may come next.



Gold Spotted Oak Borer Threatens Oak Woodlands and Ecosystems across Southern California

From San Diego County to Los Angeles County, oak trees are dying rapidly, killed by a tiny beetle called the gold spotted oak borer. In areas where the invasive pest has become established, it’s killing 80 to 90 percent of the mature oaks – a dieback that’s fundamentally changing the landscape and the ecosystem the oaks support.



South American Palm Weevil

The South American palm weevil is a serious palm pest in its native range in Mexico, Central and South America. It is highly likely that the insect has established permanent populations in southern San Diego County in an area that ranges, at least, from San Ysidro to Chula Vista. 



Embracing Functional Agricultural Biodiversity to Tap into Nature's Services

Bringing natural diversity to a farm can help boost production and benefit the bottom line. The concept is called functional agricultural biodiversity, and a work group in Oregon is helping Pacific Northwest farmers and conservationists know what plants to incorporate, insects to encourage and habitat to install to maximize their natural benefits.



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.



IPM in Montana

Montana is known as "The Last Best Place." An outdoor paradise, and home to wheat, barley and pulse crop production, Montana actively promotes integrated pest management to protect its agriculture and natural areas.



Coconut Rhinoceros Beetle

In 2015, the Invasive Species Insects Subgroup focused on coconut rhinoceros beetle, an invasive insect spreading across the Pacific. In March 2015, a work group gathered after the Hawaiian Entomological Society meeting to share the latest information and research on the beetle.



IPM in Utah

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, has alkaline soils and the risk of drought is high every year. These factors drive Utah's cropping systems - and drive the way IPM programs are developed and delivered.



Grazing Guidelines for Noxious Weed Control

Researchers, ranchers, and land managers know that livestock grazing can be a valuable and selective noxious-weed management tool, and this guide summarizes all the effective techniques.



Toolkit for Assessing IPM Outcomes and Impacts

The Western IPM Center’s IPM Adoption and Impacts Assessment Work Group, a collection of natural and social scientists from across the country, created online resources showing IPM researchers how to conduct basic impact assessments.



IPM in New Mexico

Like many states, some of the biggest IPM challenges facing New Mexico are being caused by newly arrived invasive pests, including the Bagrada bug and spotted wing Drosophila. Here's a look at the current state of IPM in New Mexico, and some of the IPM research going on there.



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.



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.



Montana Develops Weed Seedling Guide for the Northern Great Plains

Rapid and accurate identification of weeds at the seedling stage can save producers and land managers time and money but most weed identification guides only provide information about the mature stage of the plants. Not this one.



New Guide Helps Land Managers Control Medusahead

As an ecosystem-transformer species, medusahead is among the worst weeds. Not only does it compete for resources with more desirable species, but it changes ecosystem function to favor its own survival at the expense of the entire ecosystem.
