Monitoring and modeling non-native invasive green iguana population response to harvesting on Grand Cayman, Cayman Islands.

Registered hunters harvested over 1.3 million non-native invasive green iguanas () on Grand Cayman between October 2018 and August 2021. We used islandwide post-reproduction survey-based abundance estimates in August 2014-2021 and model-based abundance predictions for August 2022-2030 to assist natural resource managers with reassessment and modification of the harvest strategy due to diminishing returns to hunters paid per green iguana harvested.
