Presentation Abstract

Biodiversity is essential to healthy ecosystem function, influencing as productivity, stability, invasibility and nutrient cycling. Biodiversity loss endangers essential ecosystem services and risks unacceptable environmental consequences. Global biodiversity observations are needed to provide a better understanding of the distribution of biodiversity, to better identify high priority areas for conservation and to help maintain essential ecosystem goods and services. Traditional in situ biodiversity sampling is often limited in time and space and is usually a costly and time-consuming enterprise. Remote sensing offers the potential to observe biodiversity at multiple temporal and spatial scales and has been used to detect plant biodiversity in a range of ecosystems, typically based on relating spectral properties to the distribution of habitat, species or functional groups. Recent years have witnessed the emergence of methods using imaging spectroscopy, which is identified as the ‘only technology’ that can provide detailed spectral information to identify and quantify plant biochemical and structural traits, to assess biodiversity via plant traits or spectral information content. However, questions regarding the complex drivers of plant optical properties and the scale dependence of spectral diversity – biodiversity relationship confound diversity monitoring using remote sensing and must first be better understood before these methods can be operationally applied. In this presentation, I’ll briefly review the history of remote sensing approaches in biodiversity estimation, summarizing the pros and cons of different methods, discuss successes and major gaps of remote sensing of terrestrial plant diversity, and identify a few possible promising future directions. I’ll focus on emerging methods using spectral diversity (optical diversity) as a proxy for terrestrial plant diversity that offer to revolutionize the study of diversity in its different dimensions (phylogenetic, taxonomic, and functional diversity) from remote sensing.
