Measuring Bark pH

  • R. Kricke
Part of the NATO Science Series book series (NAIV, volume 7)


In floristic as well as mapping studies applied to, for example, pollution monitoring, bark pH is important not only for the effect it has on the lichen distribution (see [1], and chapters 3 and 4, this volume), but also for the synergistic effect with air pollution, and needs to be measured. Generally, trees with similar ranges of pH-values are comparable regarding their characteristics as phorophytes [4]. Although bark is a solid material and cannot strictly have a pH, bark pH refers to the pH of unbuffered aqueous solution in contact with the bark.
