SERVICES
Lichens are all around you, but it takes a bit of help to see them clearly.
Aspen Ecology is dedicated to helping people understand, record, conserve and enjoy lichens.
Whether you’re restoring nature, looking after land, planning a new development, or teaching or learning about biodiversity, it’s vital to appreciate the beauty of lichens and to value the important ecological role they play.

Lichen Surveys
Lichens are neglected and under-recorded biodiversity. Let Aspen Ecology help you examine your site for lichens, whether to update old data, monitor significant species or – perhaps more likely – conduct your first lichen survey.

Lichen Consultancy
Lichens are an ecologically fundamental species group. From nature-recovery work and biodiversity conservation, to land management and development planning, let Aspen Ecology help you take the value of lichens into account.

Lichen Training
Lichens are unusual organisms that demand specialist study. Whether a devoted amateur naturalist or a professional ecologist, let Aspen Ecology guide you and your team towards a fuller understanding of lichens and their habits.

Lichen Education
Lichens are curiously beautiful, and quite simply unique on Earth. Let Aspen Ecology lead a lichen talk, walk, webinar, workshop or course for your organisation or school, and participants won’t look at lichens the same way again.
THE ASPEN
Lichens have a special love of aspen trees.
Aspen Ecology honours the aspen, Populus tremula, one of the first trees to colonise Britain after the Ice Age. Its mild and multi-textured bark offers varied micro-habitats for lichens, and it hosts more species than perhaps any other British tree. Aspen can still be found across Britain, but it’s an uncommon tree in a country of lost forests. Like the lichens that love it, aspen is neglected biodiversity.

OUTREACH
Take advantage of our public lichen outreach.
Aspen Ecology’s lichen education is often available to the public through nature charities, or through our own workshops and courses. Upcoming opportunities include:
LICHEN WORKSHOP
ANGLIAN MICROSCOPY GROUP & SUFFOLK NATURALISTS’ SOCIETY
Tiny lichens hold secrets, and anyone can learn how to reveal them with microscopes! Seeing a lichen under a stereomicroscope for the first time is like descending to the surface of a new planet. Examining lichens at high magnification puts the lichen symbiosis on show: a partnership between completely different organisms that’s unique on Earth. This one-day workshop will introduce both lichens and lichen microscopy. Lichen or microscope beginners welcome.
17 MAY 2025
Crowfield Village Hall, Crowfield, Suffolk
LICHEN WORKSHOP
Understanding and appreciating lichens
SUFFOLK WILDLIFE TRUST
Lichens are probably the most fascinating yet overlooked life-forms in the natural world. In this half-day workshop, Anthony Speca will bring the compelling world of lichens out of the background. We’ll begin with an enjoyable and stimulating introduction to lichens, and then we’ll head out into Carlton Marshes Nature Reserve to observe lichens ‘in the wild’!

SWT Carlton Marshes, Carlton Colville, Suffolk
LICHEN COURSE
FIELD STUDIES COUNCIL
Lichens could be the poster child for neglected biodiversity. Even though they’re all around us, few people really notice them. But we should! Lichens aren’t just strange and beautiful, they also play an outsized ecological role. What’s more, they’re unique on Earth. This two-day course will cover all the lichen basics, including plenty of time observing lichens outdoors. You’ll build a solid understanding of lichens, and you’ll be equipped with the skills and knowledge to look more deeply into the lichens all around you.
21-22 JUNE 2025
FSC Flatford Mill, East Bergholt, Essex
FIELD NOTES AND NEWS
Follow our work and learn about the lichens we see.
Lichens are symbiotic organisms, and lichenology is a community activity. We believe in sharing field notes about the lichens we see. Keep up with our notes and news, and learn lichens with us.
TESTIMONIALS
Discover lichens with Aspen Ecology.
We do our best to make the hidden, complex and remarkable world of lichens visible, manageable and enjoyable. Here’s what others say about our work.

It was a pleasure working with Anthony for our Help Nature Thrive citizen science project. His knowledge, enthusiasm and passion for lichens was infectious: our citizen scientists left with smiles on their faces, inspired to spread the word about incredible lichens! Our biodiversity team also will benefit from the new species records collected on the surveys, with some species previously unrecorded in our central parks.
Gemma Hindi, The Royal Parks

Thank you very much for all your generous work and your very thorough report on the lichens of Gallows Field. It is really appreciated and helpful.
Jane Hamilton, Dunwich Town Trust

Anthony’s expertise, and knowledge of teaching, meant that our students were fully engaged and inquisitive throughout the whole of the ‘lichenology day’ that he delivered for us. The knowledge they gained went far beyond what they would learn as part of their curriculum, and I hope that some may even consider a career involving lichens! A massive thank you for a brilliant, engaging and informative day.
Dr Natalia Wharton, Hobart High School

[Lichens for Absolute Beginners] was a brilliant course, really informative and engaging. Thank you so much for your time, energy and enthusiasm 🙂
