The expansion of exotic species represents a very significant threat for global biodiversity. In the case of grasslands, the spreading of introduced trees and shrubs causes a huge impact, as they add new life forms to the ecosystem as well as new taxa.

This project focuses on active adaptive management of exotic woody species in one of the last remaining natural grasslands in the south of the province of Buenos Aires, Argentina. The proposal involves creating objective criteria for setting priorities for the species and areas affected, attempting to control these species, and using the information gained from control actions to detect environmental parameters related to the expansion of invasive tree species. At the same time an education programme will be initiated to emphasise the value of native vegetation, and to point out the risks associated with the spread of exotic species.
