Forest Canopy Research
Studying forest canopies is an ideal application for field spectroradiometers. Examples of research projects in evaluating forest canopy characteristics include:
- Environmental research using leaf reflectance
- Canopy architecture and nutrient concentration
- Discrimination and identification of different plant species within a heterogeneous canopy for species mapping
- Nitrogen cycling and whole canopy photosynthetic capacity
- Herb and moss biomass studies in closed canopy environments
- Leaf morphology, leaf distribution, leaf allocation, leaf orientation
- Forest canopy moisture content and forest fire risk
- Measurement of vegetation for chlorophyll, lignin, cellulose, hemi-cellulose and nitrogen
Because it is non-destructive, spectroscopy is a popular tool for remote sensing applications like canopy research. Measurement and analysis won’t change or affect the sample in any way, no chemicals or hazardous materials are used, measurements are very fast, and several different vegetation characteristics can be gleaned from a single scan. And, SPECTRAL EVOLUTION’S portable agricultural spectrometers and spectroradiometers are designed for easy use in the field, with rugged construction, light weight, and reliable operation.
Spectral signatures of materials are defined by reflectance or absorption as a function of wavelength. NIR spectroscopy measures the reflectance of infrared light wavelengths for samples and the shapes of the leaf/vegetation spectra correspond to important characteristics, including species identification, health, stress, infestation, pollution, climate change, drought, fertilization, and more – all from a single scan.
The spectra collected can be analyzed using a range of third party analysis and chemometric packages, including GRAMS, The Spectral Geologist (TSG), and others. SPECTRAL EVOLUTION’S DARWin SP Data Acquisition software saves your spectra as ASCII files for use with analysis software.
