Understanding Forest Health with Remote Sensing -Part I – A Review of Spectral Traits, Processes and Remote-Sensing Characteristics.

“Anthropogenic stress and disturbance of forest ecosystems (FES) has been increasing at all scales from local to global. In rapidly changing environments, in-situ terrestrial FES monitoring approaches have made tremendous progress but they are intensive and often integrate subjective indicators for forest health (FH). Remote sensing (RS) bridges the gaps of these limitations, by monitoring indicators of FH on different spatio-temporal scales, and in a cost-effective, rapid, repetitive and objective manner. In this paper, we provide an overview of the definitions of FH, discussing the drivers, processes, stress and adaptation mechanisms of forest plants, and how we can observe...

Linking Earth Observation and taxonomic, structural and functional biodiversity: Local to ecosystem perspectives

Earth observation (EO) techniques may provide a solution to overcome this shortcoming by measuring entities of interest at different spatial and temporal scales. This present paper provides a comprehensive overview of the role of EO to detect, describe, explain, predict and assess biodiversity. 1.Here, we focus on three main aspects related to biodiversity – taxonomic, structural and functional diversity, which integrate different levels of organization – genetic, molecular, individual, species, populations, communities, biomes, ecosystems and landscapes. These characteristics of BD help us to categorise and understand how EO-derived information is linked to BD. Furthermore, they help us to answer...
