Wondering why rock which has been exposed for very long times are only partially covered in lichens, and not entirely covered. I am thinking about Erratics which were deposited by glaciers, and have not moved since. I would expect them to be completely covered in lichens, but they seem to often have spotty lichen coverage. I would expect the coverage to be more encompassing or complete.

In reply to S. H. A. Jack.

Hi S H.A. Jack,
I wrote the lichen section of Earthlife nearly 20 years ago, and I am currently stuck in Cambodia while my library is in Greece so I cannot check the books of the papers. So all I can offer you is the names of the books I owned at that time “Lichens: An Illustrated Guide to British and Irish Species”, by Frank S. Dobson; “Understanding Lichens”, by George Baron; “Lichens”, by Oliver Gilbert and “The Lichen Symbiosis” (Oxford Biology Reader 42), by D.C. Smith

Hello!

Wonderful article, I am writing a paper on different lichen growth rates, I would be very thankful if could you direct me to your sources? Specifically for these facts:

“Rates of growth can vary from 0.5mm per year to 500mm per year.”

“Lichens grow differently at different times in their lives.”

“They grow very slowly, some species more slowly than others.”

Thank you in advance:)

I am a student currently trying to figure out if lichen prefer certain trees more than other. Specifically maple ash and hickory
