While the southern interior of the Dingus Tundra was too hostile for Canarpines, the more northern area presented them an opportunity to thrive since competiton was relatively limited in terms of trees. This would lead to the evolution of the Canarfir, by far the largest species of Canarflora with adaptations to a cold climate. The most noticeable differences from their ancestor is the fact the Canarfir females are relatively small, being less than half the size of their ancestor with a reduced trunk and shorter branches. This helps reduce their overall surface areas and so the flora loses less heat to the cold environment around them. The wing branches, which are still supported by a well developed skeleton like the rest of their bodies, have become much more fluffy and the individual "feathers" are covered in a waxy cuticle to provide extra resistance from the cold. The root system is still extensive to get as much nutrients as they can from the tundra soil the species tends to live in, although it is shorter than their ancestors to retain more heat. Female Canarfirs still have their ovaries that release spores from their ancestral mouth which is surrounded by the beak flower. The male Canarfirs have made some minor changes to live in a frigid environment, such as being larger and fluffier with a shorter foot that is also covered in fluff to provide insulation and lose less cellular heat to the cold. The semi-developed skeleton helps support their bodies and provides muscle attachments while they hunt the few small organisms that live in the area such as male Polar Canarshrubs though they will not pass up carrion when the opportunity arises. They still land on the beak flowers of the female Canarfirs, which will result in the females developing spores in their oviducts before eventually vomiting them out. The spores will be carried by the wind until they land somewhere else and become a new Canarfir, though males will emerge from the ground early on and take to the air. Much like their ancestors, the Canarfirs have a tolerance for radiation, since certain groups of fauna in the region are radioactive. While the Canarfirs thrive in the northern areas of the Dingus Tundra, they also live in the colder southern areas of the Dingus Forest though they are not as common since competition is more abundant in that area.
