Abstract:
The Intergovernmental Science-Policy
Platform on Biodiversity and Ecosystem Services
(IPBES) Thematic Assessment Report on Invasive
Alien Species and Their Control presents a “conceptual diagram of management-invasion continuum”, introducing a versatile framework to support
decision-making on the management of biological
invasions. Drawing on an extensive synthesis of current knowledge, this IPBES invasion-management
framework has been developed to broaden the scope
of existing invasion curves—which primarily overlay
generic management objectives onto a sigmoid curve
depicting the expansion of the afected area over
time—and to illustrate the applicability of the concept of efective management at diferent stages of the
biological invasion process. To introduce the IPBES
invasion-management framework to a wider audience,
this paper explains the features of the framework
and defnes the invasion-stage-based management
approaches and the potential outcomes envisaged therein. Refecting the currently limited management
options for biological invasions in marine and other
connected-water systems, unlike in terrestrial and
closed-water systems, the IPBES invasion-management framework clearly distinguishes between these
two groups of systems. For each, it presents management approaches including three key factors that decision-makers should consider concurrently: management objectives, targets, and actions. This framework
supports informed decision-making in the management of biological invasions in all ecosystems.
