What is another word for the treeline?
Pronunciation: [ðə tɹˈiːla͡ɪn] (IPA) 
The treeline is a natural boundary that separates the lower altitudes from the higher elevations, where the forest thins out and eventually gives way to alpine tundra. This line can be referred to as the timberline, tree limit, or tree boundary. In certain regions, where the trees are sparse, it is known as the bushline or forest edge. Other terms commonly used to describe the treeline include vegetation line, montane boundary, timber belt, and alpine woodland. These various synonyms all refer to the same natural occurrence, where the climate and terrain become too harsh for trees to grow, thus creating a distinct border between different ecological zones.
