Coal mining has caused large-scale disturbance on over 1.5 million acres in Appalachia. Invasive, non-native autumn olive was historically planted on former coalfields and now impedes reclamation efforts. Read about studies conducted by Virginia Tech on managing autumn olive and restoring native hardwoods.Read More

This review of the human dimensions of invasive woody plants investigates the history and purposes of introductions, people's perceptions of alien and invasive species and the impact of invasives on human activities.Read More
The ability to predict plant invasions and detect them early in the process are important considerations for invasive plant management. While agencies and landowners typically take the approach of on-the-ground searches and some may utilize habitat suitability models, these tools may not facilitate detection of incipient infestations when the species is unknown. A team set out to develop a method to identify where to look for a new invader to assist managers in focusing search efforts to areas more prone to invasion.Read More
Canada thistle can cause greater than 50% yield loss in small grain crops, but little is known about production losses when the weed invades pasture and wildlands. Change in grass, forb, and woody species production from Canada thistle infestations was evaluated in two separate studies in North Dakota.Read More

Is it possible to predict which nonnative plant species will become invasive weeds and when? Authors explore challenges related to developing invasion curves for plants using herbarium data. The goal is to better position herbaria and researchers to assist natural resource managers in prioritizing needs, supporting management decisions and developing prevention and monitoring programs.

This article describes how the impact of weedy plants can linger for years. Newly established invasive populations don’t produce the same level of lingering legacy effects as those that are long established, making early eradication imperative. READ THE FULL ABSTRACT.

Results of a regional study, to evaluate the effect of several herbicides on cool- and warm-season native grass species establishment, showed that Milestone specialty herbicide can safely be used to control susceptible invasive plants preceding grass species establishment. READ MORE
