Satellite remote sensing and the management of invasive species

Abstract

This chapter reviews opportunities for satellite remote sensing approaches to support the management of invasive species, starting by providing clear definitions of what invasive species are, in comparison, for example, with alien or exotic species. It provides an overview of sensors and approaches most relevant to the direct tracking of invasive plant species, and then expands this overview to methodologies and satellite-derived variables that can be used to predict the distribution range of invasive plant and animal species. The contribution demonstrates how satellite remote sensing information can ultimately aid optimisation of control mechanisms to prevent further spread and minimise their impacts. The various case studies introduced in this part of the book are used to discuss a number of key principles, such as the importance of the spatial and spectral configuration for reliably determining the distribution and patch sizes of invasive alien plant species; and the importance of taking into account the ecology as well as the morphological and structural features of the target species when trying to identify suitable remote sensing-based monitoring approaches.
