Due to Covid-19 we have had to cancel courses from March to 1st August, we hope you will find an event later in the year that you can attend.

The Malham Tarn area is rich in lichen species, occurring on rocks, trees, and soil, allowing the beginner to form a useful and informative collection of material. Methods of collection and examination will be explained and carried out.

Gain confidence in using simple identification keys and chemical tests, and obtain an understanding of their biology and impact on the landscape.

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 organisms, 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.
Some prior knowledge of the subject will be assumed, though beginners or those new to learning about lichens are welcome.

We anticipate that this course will run with between 4 and 40 participants.

Tutor: Allan Pentecost

Allan Pentecost has published 30 research papers on lichens, including Malham Tarn Lichen Flora. He is particularly interested in the growth of these organisms, their relationship with the substratum - and the nature of the symbiosis. As a freshwater biologist by training, he has a particular interest 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.
