The Rocky Mountain Research Station covers woodlands to desert ecoysystems from Montana to Arizona and New Mexico. Their invasive species working group has several websites of interest:

The Northern Research Station covers the 22 northeastern states from Maine to Minnesota, and West Virginia to Maryland. Invasive Species research in this region focuses on:

  • Alien Forest Pest Explorer is a portal that can be used to generate customized maps of pest distributions, including predicted future range expansion, historical damage and forest susceptibility. Currently, the Explorer contains data for 72 forest pests in the eastern US. Plans are underway to include data from other pests as well as selected invasive plants.
  • SILVAH is a silvicultural planning tool provides a format for recording presence absence and frequency data about several NNIS that are important mixed hardwood forests of the east. SILVAH flags the presence of such species and encourages users to investigate treatment options for NNIS before undertaking the silvicultural treatments that SILVAH recommends.
  • A tool for tracing the movement of an invasive insect using stable isotopes
  • Technical Innovations to Reduce Impacts of Invasive Plants in Short Rotation plantations
  • Fungus Collections at the Center for Forest Mycology Research are located at the Forest Products Laboratory in Madison, Wisconsin. The climate-controlled mycological herbarium houses more than 70,000 preserved specimens, collected since the mid-1800s. The culture collection contains more than 12,000 living isolates of 1,500 species. Details for the entire culture collection and about 25,000 herbarium specimens have been entered into an electronic database to aid information search and retrieval.
  • Tropical Forest Mycology

The Pacific Southwest Research Station covers California, Hawaii and the US-affiliated Pacific Islands. Research at PSW focuses on:

  • Sudden Oak Death, a disease caused by the introduced water mold Phytophthora ramorum
  • Invasive fish — introduced trout and other species have caused major changes in abundance and distribution of native fish, amphibians, zooplankton, and benthic invertebrates.
  • Invasive plant control — scientists at the U.S. Forest Service's Institute of Pacific Islands Forestry and colleagues in Brazil and Florida have been conducting rigorous research to develop a biological means of stopping strawberry guava's growth and spread.

The Pacific Northwest Research Station covers Oregon, Washington and Alaska.

  • The Western Wildland Environmental Threat Assessment Center develops scientific information and science-based applications, tools and technologies for policymakers, resource owners/managers/planners, regulatory agencies, communities and public so they can characterize, assess, and manage effects of important ecological disturbances and environmental changes-with particular focus on threats to ecosystem conditions and services that are valued by society.

The Southern Research Stationserves the 13 Southern States from Texas to Florida and Virginia with a research emphasis on forest threats.

  • The Eastern Forest Environmental Threat Assessment Center (EFETAC) is an interdisciplinary resource that is actively developing new technology and tools to anticipate and respond to emerging eastern forest threats. Eastern forests are vulnerable to stresses from insects and disease, wildland loss, invasive species, uncharacteristic fire, and climate change. EFETAC helps natural resource managers rapidly detect, identify, and respond to unexpected changes in the Nationís forests by using web-based tools.
  • A Field Guide to Invasive Plants has proved a popular product.
  • Southern Pine Beetles are native pests, but cause high impacts in outbreak years. Research results on SPB were recently synthesized.
