Detecting aliens: Techniques for managing invasive alien species in the Pacific Islands
summary
Literature review concludes remote sensing is feasible but underused for invasive species management across Pacific islands, with only two published applications applied to management so far. Methods tested are morphology, phenology, structure and texture metrics derived from LiDAR and satellite imagery, DEMs and canopy height models. The Pacific shows the highest invasive species per km globally, islands act as manageable living labs, but uptake stalls from limited internet, uneven infrastructure, high travel costs and loss of local geospatial expertise.
