The work documented in this report has two principal objectives: 1) to produce a review of the social, cultural, economic, environmental and biological impacts of biological invasions in Cameroon across a range of sectors, (e.g. agriculture, and conservation) and to document the management responses undertaken to address these impacts, and; 2) to outline methods that could be used to quantify the social, cultural, economic, environmental and biological impact of priority invasive species in Cameroon, with a focus on work in project pilot sites.
