Twelve amazing Lichen facts...
  • Lichen covers 8% of the landmass on planet earth
  • They inhabit nearly every environment, from polar regions to shallow oceanic areas
  • They have an essential relationship with trees by providing nitrogen 
  • A concentrated area in Russia was managed for timber and lichens and a discovery was made that once a large percentage of lichen were removed, the health of the trees declined rapidly.
  • Lichen was introduced to outer space for 14 days and taken back to earth where the organisms continued to live and flourish. 
  • Some of the oldest lichens are 4500 years old and are still living since the retreat of the last ice age. 
  • Lichens inspired xmas tinsel!
  • Reindeer lichen is 60-70% of their food source!
  • They play a vital role in rock weathering by breaking them down to produce integral minerals for all life on earth!
