The Argentine National Parks Service organized a workshop from 2-4 May in Calafate, Santa Cruz Province to advance a national strategy for invasive species. Organizers from the National Conservation Office lead participants from throughout the country’s regional scientific offices in progressing the formation of a national agenda that will complement similar efforts being advanced by the National Secretary of Environment and Sustainable Development. The event permitted authorities from diverse parts of Argentina to come together and recognize common threats and plan methodologies that will allow them to more effectively deal with the problem of introduced and invasive flora and fauna.
