The variability and variety of plant life which exists on the Earth is known as plant biodiversity. It faces threats from multiple sources such as extraction of resources, climate change, and human-driven disturbances. Remote sensing is a technology that enables the acquisition of information about an object or phenomenon without making physical contact with the object in contrast to in-situ or on-site observation. It uses satellites, drones, and air-based sensors to gather information on a specific object or area. The techniques of remote sensing can be utilized for consistent and multi-temporal analysis of plant biodiversity. This book is a detailed explanation of the various applications of remote sensing techniques with respect to plant biodiversity. It will also provide interesting topics for research, which interested readers can take up. Coherent flow of topics, student-friendly language, and extensive use of examples make this book an invaluable source of knowledge.
