Invasive species and the global strategy for plant conservation: how close has Brazil come to achieving Target 10?

Abstract

Target 10 of the Global Strategy for Plant Conservation establishes that "Effective management plans are in place to prevent new biological invasions and to manage important areas for plant diversity that are invaded" by 2020. The rationale for the target is that invasive alien species are a major threat to native plants, and thus should be excluded from areas reserved for the conservation of plant species, especially when endemic and/or threatened. In Brazil, although most management plans report the presence of invasive alien species and the need for management in federal protected areas, there are only a very limited number of management plans implemented. The national strategy on invasive alien species, published as CONABIO Resolution 05/2009, has not been implemented, so progress on policies and legislation focused on invasive alien species at the federal level has been slow. In order to reach an effective development of public policies in Brazil, federal environmental agencies must function as focal points and be in charge of coordinating actions aimed at (1) identifying priority areas for preventing and managing biological invasions, and (2) managing invasive alien species and reduce their impacts.
