Assessment of Tree Density, Tree Cover, Species Diversity and Biomass in Semi-arid Human Dominated Landscape Using Large Area Inventory and Remote Sensing Data

It is essential to develop methods for estimating species diversity and biomass in human-dominated mosaic landscapes to minimise uncertainty. The level of detail provided by very high-resolution satellite imagery enables the precise mapping and monitoring of individual trees and tree patches in trees outside forests. This work is the first of its kind and attempts to estimate tree density, tree cover, species diversity, and biomass from a comprehensive survey and very high-resolution remote-sensing data. This research compared the census of the entire tree population over a 900-ha site (local landscape) and a 15,142-ha site (regional landscape) in the Sri Sathya Sai district of Andhra Pradesh. This study mapped 47,054 tree individuals that cover a land area of 1.64
