Sphagnum tundra areas. Their northernmost populations lie in the archipelago of Svalbard, Arctic Norway, at 81° N. In the Southern Hemisphere, the largest peat areas are in southern Chile and Argentina, part of the vast Magellanic Moorland ("circa" 44,000 square km). Peat areas are also found in New Zealand and Tasmania. In the Southern Hemisphere, however, peat landscapes may contain many moss species other than "Sphagnum". "Sphagnum" species are also reported from "dripping rocks" in mountainous, subtropical Brazil. As with many other mosses, "Sphagnum" species disperse spores through the wind. The tops of spore capsules are only about 1 cm above
Portlethen Moss have been enhanced by proximity to the sea and natural defensive protection of the moss to impede intruders. From Tacitus accounts of the Roman general Agricola, it is known that the Romans were daunted by Portlethen Moss, Netherley Red Moss, Cookney Moss and other local bogs that hindered travel. This is also evidenced by the Roman Camp of Raedykes having been established immediately south of this cluster of mosses; the Romans not being able to progress further north, turned inland toward Netherley.The Portlethen Moss is near the Grampian Mountains. The ancient Causey Mounth passage specifically connected the Bridge of Dee
