You're very welcome :-) We've got another couple of films on the incredible woodland lichen we have in the UK that you may like to watch: th-cam.com/video/AEc263aQ1rQ/w-d-xo.html - The Chemical, Medicinal and Biofluorescent Properties of Lichen th-cam.com/video/YnyxpY8V-GI-/w-d-xo.html The Amazing World of Lichen
That was a great introduction, thank you! When the fungus in a lichen reproduces, do the fungus spores contain within them the symbiotic partner, or do they somehow meet up again, and re-combine once the fungus starts growing in a new location? Any recommended reading?
Great question! So, no the fungal spores disperse independently of the photobiont ... its not very clearly understood how the spores find their partner in the wild ... one idea is that the spores manage to 'steal' photobiont cells from other lichens or lichen propagules. By propagules I mean the vegetative reproduction structures (typically soredia -- powdery bits -- or isidia -- peggy bits) that lichens produce asexually, which will contain parts of both fungus and photobiont. These aren't spores, but they must often be a more reliable form of dispersal, since they are quite widespread throughout the group. My favourite introductory work on lichens is this book by William Purvis books.google.co.uk/books/about/LICHENS_PB.html?id=mAhuQgAACAAJ&redir_esc=y Cheers, Joe
animistix wow! That is amazing, and it poses more questions than it answers! Can this fungus survive without its photobiont? What sort of explanations have been given for how such symbiotic relationships began? Can the fungus accidentally pick up a different photibiont? And if so, is it called a different Lichen? Thanks for the book recommendation. I have managed to find a copy and ordered it. Hopefully it will begin to answer some of my questions! You may well have ignited a life-long interest.
I have a feeling the photobiont cells are dispersed by rain, they probably originated in the sea as all life did and first made it onto land that way. By eroding and consuming rocks, lichens produce a kind of primitive soil that mosses can colonise. When the moss dies it decomposes and enriches the soil further. Lichen are probably the origin of soil itself... what are they for? They're the reason there's life on the land at all!
Very interesting, how old could a typical lichen be? I’m interested to know how long the types take to grow, and if once picked off they can regrow in the same place? I’ve never picked them, and I wonder if some loss can be attributed to them being picked for souvenirs, hobbies and craft etc.

Tom Stenning I’m diving into this one, www.amazon.com/gp/product/0300082495/ref=ppx_yo_dt_b_asin_image_o00_s00?ie=UTF8&psc=1, available on Amazon. I’ve already got the companion book, Keys to Lichens of North America by Irwin M. Brodo.
Glad you liked it. We've released a three part series over the past few months specifically on lichen in the UK's temperate rain forests, presented by our great friend April Windle.

I have a Juniper bonsai and live in Northern California. I recently went to Lassen national park and found some lichen all on the trees and ground. I though it would be cool to get some and put it on my bonsai and I’m not sure if it will damage it because I’m not a wiz with these kinda things or even a beginner. I just really don’t want this to murder my bonsai so do you think it would be fine to spread it across the soil. I’ve watched videos and never really gotten a very straight answer and herd some things like it pathogens can infect your soil.
Great video man, it’s not easy describing something that we all don’t completely understand entirely yet. A great ancient use of lichens was extracting dye from them, Tyrian purple was the most sought after colour back in old times. Peace.
Peace indeed. The collection and processing of cudbear (Ochrolechis sp.) for dyes was a very large industry in 18th and 19th Century Scotland www.scottisharchivesforschools.org/naturalScotland/Cudbear.asp
Nice video! I would add that lichens have also been very important - and continue to be - as one of the first colonizers of land. Lichen on stone, e.g., eventually generate cracks in the stone, meaning that it breaks it down into nutrients that fall into the soil and may thus be taken up by other lifeforms.
Very interesting thank you! I know that dry lichen makes a good tinder in winter conditions for fire lightning! ( flash tinder with ferro rod) best wishes 👍🏽👍🏽
Probably only in a crisis! I'm told that the first nations peoples of NW America used to eat Bryoria (which looks like horesehair). It's not very appetising looking , and I think it was only really eaten in hard times!
Love the channel and the content. You should really consider changing your profile picture. It looks a bit dull and outdated.. Keep up with the amazing videos!
This was amazingly well done. You can see a true passion for lichen.
Thanks for your support!
Thank you for the type of video that Woodlands TV does best = fascinating and educational.
What a great passionate teacher!
A favourite of mine are Lichens 😍 what a fantastic video, top marks Joe!
Succint but thorough. Thanks for the introduction!

Great video. Information was clear and covered various topics such as anatomy, and roles they play in the ecosystem. Thank you.

I'm sold, could anyone recommend any good books on lichens? Either of the field guide or reference variety.

Great channel to geek out on :)

awesome overview!!!!! Thank you so much for making this :)
Nice one, love these short films 👍
Very interesting.
The music in the beginning is amazing.
what is that sweet little magnifier called? gotta get me one
Its called a hand lens or loupe. You want one with LED illumination. Search for LED loupe on ebay.
What sorts of hand lenses do you recommend? Does the lens include an integrated light source?
Thanks for this. Ive only just started to get an interest and this was a helpful vid. Thanks
Cool vid....Love your stuff kick on love it
I have a honeylocust tree in my yard that is absolutely covered in lichen. Every bit of the bark has a thin layer of lichen.
Awesome👏👏👍👍. Thank u so much for making such video
Thank You💖🧡💛💚💙💜

This was very nice
Very good ty.
Great vid thx
Cheers mate.
Are they edible?.
A real eye opener thank you.

Thanks for this suggestion C O we have taken it!
WoodlandsTV It’s beautiful! I love it :)
I liche it!
Effective
I think my pet snail likes to eat lichen. Sticks look oddly clean after a few days...and the snail seems happy.
Thank you woodlands James Corden
Model train layout trees!
God I love lichens
Lichen subscribe!
Whats the point of...... lol. Well done
The way he pronounces it, I keep thinking of werewolves lol
caribou eat lichen, so there is that
