The firefur replaced its ancestor the firecracker tree. Its ancestor was so tall that it kept falling down so it has reduced its size. It still towers over most other flora but won't fall down as easily. Its branches now grow in a pine tree-like formation because of the snow. Like its ancestor it has flammable nuts who only open when burned. While lighting still strikes the trees in the colder alpine regions the lower boreal and rocky biome depend more on wildfires to spread the nuts. They also have re-evolved leaves in the form of photosynthetic needles to hep it collect more sunlight. Its thick armored trunk not only helps keep it protected against fires but structurally supports it so it can grow tall.
