Paper Abstract

Forest damages in Canada have been observed to occur since the mid-1970's. Current hypotheses that attempt to explain forest declines implicate the effects of acid deposition, excess sulfur and nitrogen deposition, and elevated concentration of ozone and carbon dioxide on forest soils and nutrition as major contributors. Forest protection requires information about the pH of precipitation and aquatic ground water/soil systems along with the characterization of chemical toxicants distribution in the forest environment. Present analytical techniques for toxic chemical compounds are not well suited for field measurements. Current methods require collection of samples in the field and subsequent analysis in the laboratory. The paper discusses the possibility of applying fiber optic sensing networks for constant monitoring of pH and input/output balance of forest ecosystems to overcome most of the limitations of current methods for characterizing the distribution of chemical toxicants in the forest environment. The idea of such networks is based on sensors which couple fluorescence measurement with optical fibers offering not only a good precision and reliability but direct compatibility with fiber optic telemetry, optical data transmission systems, and optical multiplexing technology.
