The Very Few Plants of Antarctica

Without much soil, Antarctica naturally lacks much plant life. The British Antarctic Survey – which is pretty much the most reliable source of natural-history info on the continent – claims that only two flowering plants can be found on Antarctica, and then only on the peninsula, the area where the Carleton trip will go:

  • Antarctic hair grass (Deschampsia antarctica) and
  • Antarctic pearlwort (Colobanthus quitensis).

Neither is the sort of plant you’d like to have in a pot in your house. Or could, since they thrive in cold, dry, windy places, not your damn living room.

BAS reports that besides those “flowering plants,” Antarctica is home to

around 100 species of mosses, 25 species of liverworts, 300 to 400 species of lichens and 20-odd species of macro-fungi.

Incredibly, some moss and lichens live in rocks in the coldest, dryest parts of the continent. So much for being “lower plant groups,” right? Show me some dumb oak or pine that can do that.

As Antarctica warms, plants are the among the most dangerous invaders – but as you’d expect given humankind’s colossal stupidity, we also brought some invasive species to the continent. For example, Poa pratensis was introduced as part of a study in 1954-1955. It’s since been eradicated.

To prevent this kind of disaster, travelers to Antarctica – even or especially tourists a-larking – have to carefully disinfect themselves before going ashore. Glad to do it!
