A Photographic Quadrat Recording Method Employing Image Analysis of Lichens as an Indicator of Environmental Change

  • Chapter

Part of the book series: NATO Science Series ((NAIV,volume 7))

Abstract

  • To assess lichen growth, health and changes in assemblage composition by analysing digital photographic images using freely available image processing software.

  • To evaluate lichen distribution, age, reproductive capcaityand longevity.

  • To assess the impact of anthropogenic activities and of pollutants on lichens.

Rapid advances in computer hardware, digital cameras and image analysis software have allowed comprehensive studies which were impractical a few years ago. Digital photography enables visualisation of images in the field and rapid downloading of images to a computer for growth measurements [2, 4]. Young thalli easily missed in the field may be magnified and future verification of taxa is also possible.
