Stopping most invasive species of tree in Africa

Researchers propose continual cutting of stumps, application of basal bark herbicide, as well as manual uprooting as the best ways of taming the Prosopis juliflora, a kind of mesquite that has become a menace in Africa.

Experts say these methods have successfully controlled the invasive tree in Ethiopia, Kenya, and Tanzania, and even reported elimination of the herb, according to a new study led by CABI, a non-profit dealing in agricultural and environmental issues.
