Decoding Bryophytes: Earth’s Green Carpet
Meet the Bryophytes
Whilst many of us are familiar with the fungi, bryophytes often go unnoticed. This ancient class of non-vascular plants is made up of three contenders – mosses, liverworts and hornworts. Forming soft green layers upon the forest floor, rocks and tree trunks, these species are vital to building and maintaining a healthy ecosystem. However, due to their size, and subtle morphological features, species recognition has long been a challenge.
Consisting of over 20,000 species, it’s no wonder bryophytes can be hard to differentiate! DNA barcoding allows accurate species-level identification, with only the smallest amount of sample. It opens a new window of opportunity for foragers and scientists alike to delve deeper into the world of bryophytes.

Liverworts, Hornworts and Mosses
These plants thrive where others cannot, colonizing a range of environments from bare rock to lush forest. Bryophytes are involved in primary succession and initiation of ecosystems, so must be hardy enough to survive in challenging conditions – see our earlier blog post on mosses and lichens to learn more about this!
