As in many other countries in the tropics, hundreds of alien species have entered to Ethiopia, intentionally and unintentionally. The country has a long history of introduction of alien species of plants and animals, especially those that were found to be productive elsewhere and offered potential economic benefits to the country.
Studies to identify the threats of invasive plants in Ethiopia have been limited in scope, less insightful, and not sufficiently coordinated. Insufficient resources played major role in this respect. Thus, activities were focusing on problems associated with agriculture and human activity whereas, their threats to the natural ecosystems left aside.
Distribution of IAS
