Due to its site, the flora is not abundant nor numerous in the Argentinean Patagonia. The following species, mainly trees, are the most common:

Peat Mosses
One of the features of the woods in Ushuaia is the presence of peat mosses (Sphagnum magellanicum) made of vegetation remains, mainly briofitas.

Peat mosses have a tremendous capacity to retain water due to the absorbing properties of the Sphagnum moss. Thus, they become active humidity for the environment.

Among peat mosses, the white peat (from Sphagnum moss) is used as fuel or soil additive. This moss has been commercially traded for more than 150 years and lately the demand for peat to be used as fuel has increased in many countries due to the energy crisis.
