ABSTRACT
The detection and monitoring of geochemically stressed vegetation in areas of mine tailings, near surface
mineralization, and landfill sites require the use of specialized remote sensing techniques. An understanding
of how vegetation is likely to respond to specific geochemical conditions and how that response is recorded is
fundamental to technique development
In this paper, several case studies are presented. Stressed vegetation at mine tailings sites was detected from
ground and airborne spectral data. Stressed vegetation at some mineralized and landfill sites was only detected
using ground spectral techniques. These observations were supported by detailed soil, geochemical,
biogeochemical, ground and airborne spectral data.
