Harmonia+ is a first-line risk assessment scheme for potentially invasive species. It present a series of questions concerning an organism, the answers of which need to be provided by one or more assessors. Harmonia+ is described in full here http://ias.biodiversity.be/harmoniaplus. Additional information is described by D'hondt et al. (manuscript).
You can simply run the following protocol to perform assessments. However, if you want to store your assessments within our system, and further find, use or change them, you have to register and login.
In some cases, the Belgian Biodiversity Platform facilitates multi-expert assessments. Experts are invited to take part in panels and are assigned to specific group assessments.
