Nitrogen emissions and atmospheric deposition are globally significant with the potential
to alter ecosystem nutrient balance, provoking changes in vegetation composition.
Shifts in plant biochemistry are good indicators of nitrogen pollution and have been
used to monitor vegetation health. Fourier transform-infrared (FT-IR) spectroscopy has
previously been shown to be a rapid and relatively inexpensive method for evaluating
leaf biochemistry. In the present study, FT-IR spectra were collected from Galium saxatile
samples taken from sites across the United Kingdom. Spectral changes in the tissue
samples were correlated with a gradient of N deposition using partial least squares
regression analysis. We show that FT-IR analysis of G. saxatile leaf tissue is an effective
way to evaluate nitrogen deposition across the entire UK landscape.
