Abstract
Islan Dåno’ (Cocos Island) is an islet of high conservation value located 2.5 km off Guam, USA, in the Western Pacific. It has long been considered free from invasive brown treesnakes (Boiga irregularis; BTS). A recently confirmed breeding population of BTS puts its wildlife populations, including U.S. Endangered Species Act-listed lizard and bird species, at risk. In response, we established Guam’s first volunteer group dedicated to BTS eradication, which we named Friends of Islan Dåno’. We provided training to local volunteer snake searchers and organized regular night searches for BTS on Islan Dåno’. We completed 25 searches between June 2021 and January 2022, which were attended by 89 individual volunteers and removed 14 BTS from the island. This case study provides an example of how public participation can be successfully promoted within the context of a complex multi-agency invasive species eradication project.
