Join Richard Todd, an enthusiastic amateur lichenologist, as we explore the estate in search of different forms of lichen. This ‘Beginner's Guide to Lichens’ promises to introduce you to all three basic growth forms: flat/crusty (crustose), leaf-like (foliose) and bushy(fruticose), as they are found in the environment. Lichens are fascinating and complex organisms. They’re not plants, but are a composite organism made up of a fungus and either an algae or cyanobacteria. The two components exist in a symbiotic relationship – both receiving benefit from the arrangement. Lichens are found in almost every habitat on earth, and can live on most surfaces, including wood, concrete, trees, walls and rocks as we’ll demonstrate during the walk. We will also be able to observe some of the methods lichens use to reproduce. Lichens are valuable members of ecosystems, providing food and shelter for both vertebrates and invertebrates so we’ll consider their role in the ecosystem as we go.
Richard is an enthusiastic amateur lichenologist, who discovered lichens whilst volunteering at Burnham Beeches National Nature Reserve over three years ago. His passion for these amazing organisms has been increasing ever since. Also joining us on the day will be local ecologist Martin Woolner. All proceeds will be donated to Wild Maidenhead.
Format of the Day:
9.30 am Welcome and Illustrated Talk – Introducing Lichens.
10 am Estate Walk searching for examples of lichens in different habitats.
11.30 am Refreshments, Q and A, and further information on the ecology of lichens and what lichen can do for us!
Please bring a hand lens or magnifying glass if you have one.
This walk covers uneven ground so it may not be suitable for those with mobility issues. We recommend sturdy footwear.
