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.
This one-day course is designed to introduce lichens to naturalists and students (sixth form and undergraduate) – including those whose appetites have been whetted by participation in the OPAL air pollution survey. No previous knowledge is assumed.
The day will focus on identifying lichens, explaining what lichens are and how they can be distinguished in the field.
At the end of the day, participants can expect to feel confident in the naming of a range of common species, have a small collection of reference specimens, and have sufficient background for projects using lichens as bioindicators of environmental conditions.
The Malham Tarn area is rich in lichen species. Over 300 have been recorded within just three miles of the Field
Centre. There is a Field Studies Council publication listing them and providing descriptions of their ecology.
Excursions will be on foot from the Field Centre and will not be arduous (two km).
A British Lichen Society course.
We anticipate that this course will run with between 5 and 20 participants.
Tutor: Allan PentecostAllan 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.
