There's not much wild life in a highland climate due to the extreme temperatures and elevations. Only animals like mountain lions, snow leopards, cattle/cow and little insects.
how about are there any vegetation in the highland climate zone
The Vegetation for the Highland climate is very little but there is some. There are no trees above the Tree line.
