Course: Lichens: Ecology and Identification - HAU

This 2.5 day beginner to intermediate course will introduce you to lichens – the remarkable partnership between fungi and algae.

Lichens are more than just a biological curiosity; they are key players in our ecosystems, serving as indicators of air pollution and ecosystem integrity. This course equips students with the scientific knowledge and practical skills to identify lichen species, understand their life cycles, and appreciate their ecological significance.

This course includes:

• An introduction to lichen ecology and biology.
• Identification of lichens.
• Techniques for field collection and preservation of specimens, as well as introducing recording and surveys.
• Discussion of lichens as environmental indicators.

From the start of 2027, when you purchase this course, a free copy of our Lichens on Twigs Guide will be posted to you. If you already have a copy, why not share it with family, friends, or colleagues.

Central to the course is the application of lichens as bioindicators, a tool for environmental scientists to assess air quality and the impact of pollutants on natural habitats. Learners will engage in field surveys, learning to identify and catalogue lichen diversity within various habitats and use this data to assess air quality and habitat health. This practical work is supported by classroom sessions that provide a theoretical underpinning of the biology and ecology of lichens, including their symbiotic nature, reproductive strategies, and adaptability to different environmental conditions.

By the end of the course, you will be able to:

• Demonstrate an ability to identify a selection of common lichen species using a range of identification resources.
• Critically evaluate the role that lichens have as ecological indicators and their use in indicating air and habitat quality.
• Apply knowledge of lichen biology and ecology to real-world scenarios in environmental monitoring and conservation.
