Background and challenges

Existing models suffer from a lack of ecological realism, from a high level of complexity that makes them hardly usable for applied management problems, and from a relative disconnection from the needs of environmental managers. In other words, although these models have all the ingredients needed for becoming decision-making tools, they remain mainly restricted to the academic sphere and their results have little impact on management.

Resources

To fill this gap, SPABIO builds on a transdisciplinary collaboration between ecologists, economists and wildlife managers in order to:

1. develop a new class of ecologically-realistic, bio-economic models that are directly applicable to IAS management on the field,
2. provide a proof of concept for these new tools using the case of water primrose in the Brière Regional Natural Park,
3. prepare the application of the modelling framework to other IAS problems in various contexts.
