Lichens in the Dales: An Introductory Course

Start to identify lichens on this introductory lichen identification course. The Malham Tarn area is rich in lichen species, over 300 having been collected within five miles of the Field Centre. A wide range of forms is present, occurring on rocks, trees and soil, allowing the beginner to assemble a useful and informative collection of material.

The nature of the lichens and methods used to study them in the field and at home will be explained. Methods of collection and examination will be provided and local collections from the field will be returned to the Field Centre for further study. This will include the close observation of the symbiosis and reproduction of lichens.

At the end of the course, participants should be able to identify lichens as distinct from other lower plants, and place them approximately in their morphological group or family. They should also acquire confidence in using simple identification keys and chemical tests and obtain an understanding of their biology and impact on the landscape.

This is a course for beginners or those with little experience with lichens, though the more experienced are also welcome.

Allan Pentecost has published 30 research papers on lichens, including Malham Tarn Lichen Flora. He is particularly interested in the growth of these plants, their relationship with the substratum - and the nature of the symbiosis. As a freshwater biologist by training, he is interested especially in those lichens occurring in or near water, and those containing blue-green algae. He has been visiting and collecting in the Malham Tarn area for over 30 years.
