Ecology and Management of Invasive Species
Hudsonia conducts detailed studies of the ecological relationships of an invader to other organisms, and develops management approaches that integrate these ecological relationships with site-specific goals and other ecosystem services such as water quality maintenance.
We currently focus on purple loosestrife, common reed (Phragmites) , water-chestnut, and Japanese knotweed. We have prepared a Phragmites Management Sourcebook and we offer a professional workshop on Phragmites ecology and management.
We have also published reviews of the ecology and management of water-chestnut and Japanese knotweed.
