Cefn Conwy

The CEFN Conwy project is designed to enhance the technical knowledge and environmental management skills of farmers in rural Conwy

Invasive Woody Plants in the Tropics
The Invasive Woody Plants in the Tropics research group, based at the University of Wales, Bangor, UK, has undertaken two major field studies in Jamaica and Tanzania, together with a global review of invasions resulting in a comprehensive database, an analysis of common characteristics and recommendations for management and control.
