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

Description: 

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. Invasive Plants Field and Reference Guide: An Ecological Perspective of Plant Invaders of Forests and Woodlands-master publication.

Pest Alert Browntail Moth NA-PR-04-02

Description: 

Pest Alert - The browntail moth, Euproctis chrysorrhoea, a native of Europe, was first found in North America in Somerville, Massachusetts, in the spring of 1897. Browntail moth caterpillars feed on leaves of many hardwood trees and shrubs. At high population levels, caterpillars may completely defoliate the host. Common host trees and shrubs include apple, oak, cherry, hawthorn, serviceberry, rugosa rose, and bayberry. Browntail moth caterpillar hairs can cause a skin rash on humans similar to that caused by poison ivy.

Implementation and status of biological control of the hemlock woolly adelgid

Description: 

The hemlock woolly adelgid (HWA), Adelges tsugae Annand (Hempitera: Adelgidae), threatens the health and sustainability of the native eastern North American hemlocks, Tsuga canadensis (L.) Carrière and T. caroliniana Engelman. The lineage of HWA that was introduced to the eastern United States came from Japan sometime prior to 1951, and did not co-evolve with eastern North American forest ecosystems (Havill et al. 2006).

Invasive Plants Field and Reference Guide: An Ecological Perspective of Plant Invaders of Forests and Woodlands (supplement 1)

Description: 

Supplement 1 makes the following changes to the original guide, which was published in 2004. Replaces the title page. Corrects and clarifies information in the original guide for two species: Microstegium vimineum(Japanese stiltgrass) and Rosa multiflora (multiflora rose). Replaces the Species List. Adds descriptions with photos for five new species. These species are among a long list of priority species and were selected over others for one key reason. Literature and research on them currently are relatively abundant.
