Plant Invaders of Mid-Atlantic Natural Areas, Field Guide is a portable resource for both novice and expert. This practical book is intended for people interested in maintaining or restoring natural areas - from parks and preserves to residential landscapes. Use this book as an introduction to invasive plants to help you recognize, report, prevent, control and teach others about them. Managing invasive plants is crucial if we want our native plants and animals to thrive. Plant Invaders provides information on 92 aquatic and terrestrial invasive species threatening our region, guidance on control methods, discussion of the effects of climate change on invasive plants, explanations and maps of ecoregions and physiographic provinces, and suggestions for native plant alternatives.

This resolution addresses invasive species management and adds substantial new policy, including: a call to address the destructive relationship between invasive grasses and wildfires; mechanisms to enhance regional invasive species research, planning, and coordination; and recommendations to Congress and federal agencies on improving invasive species management on federal lands and supporting state-led management efforts.

WGA resolutions are in effect for three years and then expire or are renewed. See all current WGA Policy Resolutions.

This policy resolution addresses the management of forest and rangelands in coordination with federal agencies and addresses issues including wildland fire, invasive spaces, and collaborative efforts.

Pollinators are essential to the survival and health of natural ecosystems but are declining worldwide. Because of this, there is urgent need to restore pollinators and the services they provide. One way to address this need is to use pollinator-friendly plants in revegetation projects (roadsides, fire rehabilitation, etc.), but land managers lack information about which plants are best for pollinators. Rocky Mountain Research Station and partners at Montana State University are assessing the pollinator-friendliness of native plant species that are available for revegetation in Montana to produce a guide identifying the best species mixes to support the greatest number of species and abundance of pollinators. This webinar is part of our Science You Can Use series of land-management focused webinars.

Since 2002, forests in the southeastern U.S. have struggled against a disease called laurel wilt. In 18 years, laurel wilt has spread to 11 southeastern states and killed hundreds of millions of trees. A review article by USDA Forest Service scientist Rabiu Olatinwo reflects on the origins and spread of laurel wilt throughout the last several years. Olatinwo, a research plant pathologist at the SRS, published this research with recently retired plant pathologist Stephen Fraedrich and research entomologist Bud Mayfield in the journal Forests.

Watercraft Inspection and Decontamination Programs - Many Western states instituted watercraft inspection and decontamination programs after the discovery of invasive mussels in Lake Mead in 2007. This section provides resources on mandated watercraft inspection and decontamination programs, as well as some non-mandated but state-funded watercraft inspection efforts.

Aquatic Invasive Species Decals - Some U.S. states require that boaters purchase an aquatic invasive species decal (sometimes called a stamp, sticker, or permit) before operating watercraft in that state. Many of these regulations were instituted as a response to the spread of zebra mussels and quagga mussels into the Western U.S. Fees from the purchase of these decals are typically used to fund local aquatic invasive species outreach and prevention activities.

Contains invited papers, short contributions, abstracts, and working group summaries from the Beech Bark Disease Symposium in Saranac Lake, NY, June 16-18, 2004.

The Rapid Response Plan for Management and Control of the Chinese Mitten Crab is intended to guide efforts to mitigate the further introduction and spread of the Chinese mitten crab in the northeastern United States and Canada. Due to the unique challenges of invasive species introductions to marine and coastal ecosystems, the mitten crab and other existing and potential marine invasive species are more difficult and often more costly to manage or control than freshwater aquatic or terrestrial invasive species. This document focuses on the use of early detection and rapid response as a tool to prevent the introduction and spread of Chinese mitten crabs and other crabs belonging to the genus Eriocheir throughout northeastern United States and Atlantic Canada. The primary goal of this plan is to provide information needed to support local, state, and regional efforts to prevent and control the spread of Chinese mitten crabs throughout northeastern United States and Atlantic Canada. For more information on the development of this plan, see Early Detection and Rapid Response Plan for the Invasive Chinese Mitten Crab.

Inspection and decontamination refers to the process of checking all parts of a boat to ensure that it is not carrying any invasive species and appropriately cleaning a boat if it is. This category examines how the relevant management agency implements watercraft inspection and decontamination programs throughout their jurisdiction.

The U.S. Forest Service has developed a number of Regional documents for invasive species management for the Southwestern Region (Region 3). Region 3 covers national forests and grasslands in Arizona and New Mexico along with national grasslands in western Oklahoma and the Texas panhandle.Region 3 covers national forests and grasslands in Arizona and New Mexico along with national grasslands in western Oklahoma and the Texas panhandle.

Climate change is likely to bring dozens of new invasive plants to the Northeast. Despite their invasive tendencies, many of these species are sold as ornamental plants in slightly warmer climates, but are not yet a large part of nursery sales in the Northeast. By avoiding these species, we protect our native ecosystems from future invasive species impacts. We also present alternative native plants that provide similar aesthetics while also supporting biodiversity.

Provides planting recommendations for present and future conditions using native species adapted to both current and future hardiness zones. An estimated 80% of ornamental plants for sale are non-native. This means that the average yard does a poor job of supporting native flora and fauna. By shifting our plantings towards natives, we can dramatically increase the diversity of bees, butterflies, birds and other animals. In contrast, non-native plants do not support local food webs and can become invasive. Native plants increase biodiversity and reduce risks associated with invasive species, which supports resilient ecosystems in the face of climate change.

Biocontrol is an important management tool that utilizes one species (a biocontrol agent) to control another (a target host) and can be an effective approach for controlling populations of invasive species across broad spatial scales. There are growing concerns that mismatches between how biocontrol agents and their hosts respond to climate change could alter the efficacy of current and future biocontrol programs.

The four Regional Integrated Pest Management (IPM) Centers serve as a hub for multi-state partnerships and communication networks, linking researchers, growers, extension educators, commodity organizations, environmental groups, pest control professionals, government agencies and others. The regions include: Northern IPM Center, Southern IPM Center, North Central IPM Center, and the Western IPM Center.

Funded by the USDA National Institute of Food and Agriculture to promote IPM, the Centers also coordinate, enhance, and facilitate the flow of resources and information in integrated pest management on a regional basis, including grants management, data acquisition and sharing, infrastructure development, and the documentation needed to provide accountability for resources used. Each regional center focuses on national efforts while maintaining the regional nature required for effective IPM programs.

Provides a searchable database for various key contacts, coordinators and experts.

One of the WIGL Collaborative’s major initial projects was to research and summarize the existing federal, state and provincial laws and regulations that relate to invasive woody plants. You can use this page to find information about the laws of states or provinces in the Great Lakes Region. You can also use our map tool for an at-a-glance comparison of how the Woody Invasives of the Great Lakes are regulated in the region.
