    Yes, a reminder to “walk lightly on the earth”. Thank you.

    Thanks for using Go Botany. Those of us involved with NEWFS on a variety of levels are very proud of it. I just discovered after a recent trip to Alberta that that I could find “presence” of plants in Canadian provinces. And, Daniel, I snuck into BC by accident on a trip to Emerald Lake. I still have your neck of the woods on my bucket list.

    Fascinating! I love these sorts of “Then and Now” photographs, especially of lichens. Thanks for this one and all you do.

    Thanks so much for sharing this. For me it is easiest to compare the pale gray lichens at left center of both photos, (on the rock which is furthest back). They have grown enough to coalesce – slow compared to most macrolichens, but fast compared to 0.03mm/year measured for some crusts on Baffin Island. Some large slow growing lichens must be many thousands of years old.

    Possibly of interest are some photos which I made at 7 year intervals (also had problem with shift of perspective) – https://www.flickr.com/photos/29750062@N06/33217830904/in/photostream/

    I saw this the other day on my phone and didn’t really have time to comment during the week. I really like the way you get the message across here, Daniel. It is delivered subtlety, yet powerfully in a lead-by-example sort of way. Nicely done.

    And while I do enjoy large, flashy inflorescences I do appreciate that BPOTD features some microflora and some unusual perspectives on occasion. I am a definite fan.
