Invasive Plants Field and Reference Guide: An Ecological Perspective of Plant Invaders of Forests and Woodlands (parent document)


There are many field guides available about invasive plants and their identification. The purpose of this particular field guide is to give a scientific synthesis of what is known about the behavior of such species in managed, disturbed, and pristine forested systems in addition to key information for accurate identification. Such information will be helpful when prioritizing research questions and choosing the best control strategies.

Controlling Invasive Plants in Priority Landscapes in Maryland

Nonnative invasive plants are increasing in number of locations and severity, making them one of the toughest long-term land management issues. Invasive plants pose significant threats to ecologic integrity, forest regeneration, water quality, and resilience of native forests. There are now too many nonnative invasive species to control them everywhere, so choosing critical locations and designing effective control treatments are needed for meaningful habitat conservation.

Forest Health Protection

Forest Health Protection programs emphasize protecting the long-term health and sustainability of our forests. Our major responsibilities are to assist the States with implementing their forest health programs and to provide forest health support on National Forests and other Federal lands. Activities include identification and evaluation of insect and disease problems, provision of resource materials and management recommendations in forests and nurseries, training in hazard tree management, and assistance with major forest pest control projects.

Ailanthus treatment

We have over 250 specialists in the areas of forest entomology, forest pathology, invasive plants, pesticide use, survey and monitoring, suppression and control, assessment and applied sciences, and other forest health-related services.

Invasive Plant Partnership Improves New Hampshire’s Coastal Watershed

Seven major river basins drain the more than 1,000 square miles of New Hampshire’s coastal watershed into the Atlantic Ocean. The region includes diverse ecosystems— coastal bays, forests, agricultural lands, tidal rivers, salt marshes, freshwater rivers, and lakes and ponds. This coastal watershed area provides essential habitats for more than 130 rare native species. Invasive species pose a major threat to these delicate and diverse ecosystems. Native plants often cannot compete with invasive plants that displace them after becoming established.
