Welcome to this online survey which aims to assess the potential impact of invasive alien species management methods on ecosystem services.

The survey is divided into three parts: management methods for crayfish, management methods for aquatic plant species and management methods for terrestrial plant species. Management methods evaluated in this survey were selected based on a preliminary work which only identified best management practices. Methods such as the use of herbicides, biocides or other chemical products were, however, not included for legal reasons.
