Morphology

treeline = tree + line (semi-transparent) = tree + line

Composed of 'tree' + 'line' with the sense 'boundary of tree growth' which is a technical/ecological extension not immediately obvious to all learners.

Etymology

The word treeline is made of tree and line, so imagine a 'line' on a mountain that shows the 'highest place' where trees can grow. That's why being above the treeline means you are above the place where trees can live.
