Qinngua Valley in Greenland

Iceland has significant ice caps, while Greenland, despite its name, has a small natural forest. The forest is located in the Qinngua Valley, also known as Paradisdalen or "paradise valley". This valley has a borderline sub-arctic climate, with temperatures rising above 10°C in the summer, making it possible for trees to grow. The valley's unique climate is due to its location at the southern tip of the island and the presence of tall mountains that block cold winds from the interior ice cap. Around 300 species of plants grow in this isolated glacial valley, including gray-leaf willows, downy birches, and Greenlandic mountain ash. The latter two species are Old World and New World species that do not natively grow together anywhere else. Despite being a hotspot of biodiversity compared to the rest of Greenland, the valley is still less diverse than most of the world's lands. Norse settlers once lived near the valley, but their exact location is disputed, with some claiming it was the site of Erik the Red's estate, Brattahlíð. However, the consensus is that Brattahlíð was located further northwest at Qassiarsuk. A small Augustinian monastery was also located 12 kilometers north of the valley, by Ketilsfjord.
