Meet the Treetop Lichen

Lichens contribute such beautiful colors to our redwood forests, growing elegantly on trees, fallen logs, and rocks. Each lichen you see is actually a symbiotic partnership — algae or cyanobacteria wrapped up in a fungal package. Thanks to canopy biologists Rikke Reese Næsborg, Cameron Williams, Marie Antoine, and Stephen Sillett, those of us on the ground now have a  window into the tremendous lichen diversity aloft in the redwood forest canopy! Below are a few close-up portraits and descriptions by Rikke Reese Næsborg of the amazing lichens found in the trees tops of Muir Woods National Monument during BioBlitz 2014.

See photos of the lichens being collected in the Muir Woods canopy by reading last week’s blog post, First Canopy Exploration at Muir Woods.
