Constructing Standard Invasion Curves from Herbarium Data—Toward Increased Predictability of Plant Invasions

by Pedro M. Antunes and Brandon Schamp. Invasive Plant Science and Management, 10(4):293-303. 2017.


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.

Best Management Practices for Preventing the Spread of Invasive Plants is a 42-minute training video designed for land managers and those who manage road or utility corridors, which can be key pathways for the spread of invasive plants. The video summarizes key content from our BMP manuals on the same topic. We cover ways to prevent the movement of invasive plant propagules, the importance of minimizing soil and vegetation disturbance, the need to incorporate prevention practices into project planning, and how promoting awareness within our organization can enhance prevention.

Weed Seed Dispersal by Vehicles

Weed Seed Dispersal by Vehicles
Understanding weed seed transport by vehicles is important to help direct prevention activities (wash stations, road closures, public education, etc.) to reduce weed seed dispersal along trails and roads. Studies conducted by Montana State University measured the number and type of seeds picked up by vehicles and the distance seeds were transported.Read More
