The tree line is the edge of a habitat at which trees are capable of growing and beyond which they are not. It is found at high elevations and high latitudes. Beyond the tree line, trees cannot tolerate the environmental conditions. The tree line is sometimes distinguished from a lower timberline, which is the line below which trees form a forest with a closed canopy.
Temperate rainforests are rainforests with coniferous or broadleaf forests that occur in the temperate zone and receive heavy rain.
Rila is the highest mountain range of Bulgaria, the Balkan Peninsula, and Southeast Europe. It is situated in southwestern Bulgaria and forms part of the Rila–Rhodope Massif. The highest summit is Musala at an elevation of 2,925 m which makes Rila the sixth highest mountain range in Europe after the Caucasus, the Alps, Sierra Nevada, the Pyrenees and Mount Etna, and the highest one between the Alps and the Caucasus. It spans a territory of 2,629 km2 with an average elevation of 1487 m. The mountain is believed to have been named after the river of the same name, which comes from the Old Bulgarian verb "рыти" meaning "to grub".
When the Spanish arrived, they divided Peru into three main regions: the coastal region, that is bounded by the Pacific Ocean; the highlands, that is located on the Andean Heights, and the jungle, that is located on the Amazonian Jungle. But Javier Pulgar Vidal, a geographer who studied the biogeographic reality of the Peruvian territory for a long time, proposed the creation of eight Natural Regions. In 1941, he presented his thesis "Las Ocho Regiones Naturales del Perú" at the III General Assembly of the Pan-American Institute of Geography and History.
The Sierra Nevada subalpine zone refers to a biotic zone below treeline in the Sierra Nevada mountain range of California, United States. This subalpine zone is positioned between the upper montane zone at its lower limit, and tree line at its upper limit.
The Jungfrau-Aletsch protected area is located in south-western Switzerland between the cantons of Bern and Valais. It is a mountainous region in the easternmost side of the Bernese Alps, containing the northern wall of Jungfrau and Eiger, and the largest glaciated area in western Eurasia, comprising the Aletsch Glacier. The Jungfrau-Aletsch protected area is the first World Natural Heritage site in the Alps; it was inscribed in 2001.
Pinyon–juniper woodland, also spelled piñon–juniper woodland, is a biome found mid-elevations in arid regions of the Western United States, characterized by being an open forest dominated by low, bushy, evergreen junipers, pinyon pines, and their associates. At lower elevations, junipers often predominate and trees are spaced widely, bordering on and mingling with grassland or shrubland, but as elevation increases, pinyon pines become common and trees grow closer, forming denser canopies. Historically, pinyon-juniper woodland provided a vital source of fuel and food for indigenous peoples of the American Southwest. The nuts continue to be a traditional indigenous food, and because nut-collecting was also adopted by the Spanish in the 1500s, the nuts are also traditionally harvested by some Hispanic communities.
Cumbres del Ajusco National Park is one of many national parks near Mexico City, DF. The Ajusco is known for its high elevations reaching 3,900 meters (12,795 ft) above sea level and is visible from any part of Mexico city. The park is characterized by pine-oak forests and high mountain grassland. Cumbres del Ajusco means "watered grove peaks", an appropriate name for this mountainous region covered with lush green forest with many flowers due to a fair amount of precipitation. The Balsas and Lerma rivers begin in the heart of the Cumbres del Ajusco.

Central Europe contains several life zones, depending on location and elevation.
The Cuban pine forests are a tropical coniferous forest ecoregion on the Caribbean islands of Cuba and Isla de la Juventud. They cover an area of 6,400 km2 (2,500 sq mi), occurring in separate sections in eastern Cuba and western Cuba and Isla de la Juventud.
The East African montane forests is a montane tropical moist forest ecoregion of eastern Africa. The ecoregion comprises several separate areas above 2000 meters in the mountains of South Sudan, Uganda, Kenya, and Tanzania.
The Southeastern conifer forests are a temperate coniferous forest ecoregion of the southeastern United States. It is the largest conifer forest ecoregion east of the Mississippi River. It is also the southernmost instance of temperate coniferous forest within the Nearctic realm.
The Mount Ilgaz National Park is a protected area established on June 2, 1976 and located on the Ilgaz Mountains at the borderline between Kastamonu Province and Çankırı Province in the western Black Sea Region of Turkey. Natural resources and its potential for recreational activities are the main values of the national park, which stretches over an area of 742.38 ha.
Mixed conifer forest is a vegetation type dominated by a mixture of broadleaf trees and conifers. It is generally located in mountains, below the upper montane vegetation type.

The Northeastern Spain and Southern France Mediterranean forests is a Mediterranean forests, woodlands, and scrub ecoregion in southwestern Europe. It occupies the Mediterranean coastal region of northeastern Spain, Southern France, the Balearic Islands and a small part of Italy.
The Central Afghan Mountains xeric woodlands ecoregion covers the xeric (dry) eastern and southern slopes of the central mountain range of Afghanistan, between the sandy desert to the south and the alpine meadows in the higher, wetter region to the north. Despite the 'woodlands' in the ecoregion name, very little of the territory is forested – less than 1% – but is instead sparse vegetation or herbaceous cover.
