This 2018 report by Philip (Pike) Brown, Quentin Paynter, Emilia Tjernström and Arne Witt contains the results of cost-benefit and cost-effectiveness studies of a variety of invasive species problems in the Comoro and Seychelles Islands, carried out as part of IUCN’s Inva’Ziles project. The study analyses management options for Acacia concinna on Mahé island (Seychelles), Black Rat Rattus rattus in the Vallée de Mai World Heritage Site on Praslin Island (Seychelles), and the shrub Clidemia hirta on Ngazidja Island (Comoros).

During the 2016 World Conservation Congress in Hawai’i, there was a call from the IUCN Invasive Species Specialist Group, the host community in Hawai’i, and experts, protected area managers, representatives of governments and intergovernmental bodies, NGOs and others, for greater action on invasive species. This resulted in the Honolulu Challenge.
In September 2016, project staff Alan Tye, Olivier Hasinger and Kevin Smith organised and participated in several events at the World Conservation Congress (WCC) aimed at furthering Inva’Ziles objectives, especially the global guidance document.
