Above the treetops.
The altitude of timberline varies around the globe. The two main factors are latitude and global climate patterns. Near the poles, the timberline is at sea level. The generally colder temperatures, extremely harsh winters, and lack of overhead sunlight prevent trees from growing in these regions. As you near the equator, the altitude of timberline increases. The highest known timberline is around 16000 feet. Generally warmer climates, less extreme seasonal shifts, and more overhead sunlight allow trees to survive at higher altitudes in the tropics. Even at the same latitude, timberlines may vary. As a general rule, the timberline on the western slope of a mountain range in the United States will be higher than the timberline on the eastern slope due to increased precipitation as warm moist air is pushed up by the mountains. The drier climates found on the eastern slopes of the same ranges are not as conducive to tree growth. Long term climate shift will gradually move timberlines, but this takes a very, very long time. Seeds from trees will often lay dormant for years before even sprouting, and take many more years to grow into an appreciable "tree," especially at extremely high altitudes. A warm or cold shift for a few decades will not have a noticeable impact, but over the course of several centuries, the line may shift a little.
The subalpine forest is found just below timberline. It is characterized by coniferous trees such as spruce, fir, and pine, adapted to cold temperatures and poor soil conditions at higher elevations. This type of forest often transitions into alpine tundra as elevation increases.
found in cold regions, mostly north of the Arctic Circle (Arctic tundra) or above the timberline on high mountains (alpine tundra).
The permanently frozen ground in the northern latitudes is called permafrost. The layer closest to the surface that thaws during the summer is also part of the permafrost, but is called the active layer. Permafrost is a major feature of the tundra biome.In physical geography, tundra is a biome where the tree growth is hindered by low temperatures and short growing seasons. The term tundra comes from Kildin Sami tūndâr, which means "uplands, treeless mountain tract." There are two types of tundra: Arctic tundra (which also occurs in Antarctica) and alpine tundra. In tundra, the vegetation is composed of dwarf shrubs, sedges and grasses, mosses, and lichens. Scattered trees grow in some tundra. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline.

Can a timberline be found in nebraska?
A timberline is an imaginary line where trees do not grow.
Timberline Twister was created in 1983.
Timberline Lodge was created in 1935.

I just used timberline in a sentence
The timberline is the highest elevation on a mountain that trees can grow.
The timberline usually refers to the point at which trees are no longer found on mountainsides. In general, there is very little vegetation above the timberline.
Trees grow at a certain temperature and have trouble above a certain level. That is called the timberline. It turns to grass or gravel at the timberline.
Timberline Secondary School was created in 1997.
It is the timberline.
