Capacity and capability of remote sensing to inform invasive plant species management in the Pacific Islands region

Conservation Biology, Volume 39, Issue 1, February 2025.
Abstract The Pacific Islands region is home to several of the world's biodiversity hotspots, yet its unique flora and fauna are under threat because of biological invasions. These invasions are likely to proliferate as human activity increases and large‐scale natural disturbances unfold, exacerbated by climate change. Remote sensing data and techniques
