  author={Georg Miehe and Sabine Miehe and J. C. Vogel and Sonam Co and Duo La},
Abstract Three new records of the highest treelines in the northern hemisphere are presented here, based on the definition of a “tree.” The tree species with the highest treeline in the northern hemisphere is Juniperus tibetica Kom. The highest forest stand is located at 4900 m in southeast Tibet. The highest tree stands of Juniperus indica Bertol. in the Himalaya were found in northern Bhutan at 4750 m. Information from such observations is decisive for the development of hypotheses on the… 

An unusually high shrubline on the Tibetan Plateau.

Juniperus trees and shrubs at their upper distributional margins likely experience the highest warming rates of all junipers and are recognized as sensitive ecological indicators of responses of land ecosystems to shifting abiotic and biotic conditions as they are easily relocated over time.

Little change in the fir tree-line position on the southeastern Tibetan Plateau after 200 years of warming.

The warming in the past 200 yr is already having a significant impact on the population density of the trees, but not on the position of the Smith fir tree line, despite warming on the Tibetan Plateau.

Tree-ring evidence of recent abnormal warming on the southeast Tibetan Plateau

We developed four Georgei fir (Abies georgei var. smithii) tree-ring width chronologies at the timberline in the Sygera Mts. in southeast Tibet, China. All individual standard chronologies and a

Treeline dynamics with climate change at the central Nepal Himalaya

Abstract. Treeline shifting in tandem with climate change has widely been reported from various parts of the world. In Nepal, several impacts of climate change on the physical environment have been

An inventory of isolated tree stands surrounded by desert pastures in Southern Tibet (A.R. Xizang, China) revealed more than 50 sites with vigorous trees of Juniperus convallium Rehder & E.H. Wilson

Patterns of floristic and functional diversity in two treeline ecotone sites of Kashmir Himalaya

Globally, the treelines at higher elevations in mountains are reported to be advancing up-slope in response to recent climate warming. However, little is known about the treeline advancement in the

Has tree density increased at alpine treelines on the eastern Tibetan Plateau?

Treeline densification, along with increased growth rates, is considered a primary manifestation of climate warming at alpine treelines. However, treeline densification has typically been inferred

Elevation Pattern in Growth Coherency on the Southeastern Tibetan Plateau

It is concluded that individual heterogeneity and microhabitat diversity are important features for treeline trees that may dampen the growth synchrony in trees and the general expectation of growth convergence among individuals with increasing altitude is not supported.

The Timberline Ecotone in the Himalayan Region : An Ecological Review

T he Himalayan region has the highest and most diverse treeline in the world. Lying between montane forests and alpine vegetation, the alpine timberline is a particularly conspicuous boundary and has

Based on comprehensive evaluations and analyses of existing literature and data sources, a review of geographical and ecological aspects of the upper timberline in the Himalayan mountain system is

An inventory of forest relicts in the pastures of Southern Tibet (Xizang A.R., China)

An inventory of isolated tree stands surrounded by desert pastures in Southern Tibet (A.R. Xizang, China) revealed more than 50 sites with vigorous trees of Juniperus convallium Rehder & E.H. Wilson

Sacred Forests in Tibet

Abstract The treeless desertlike environments of southern Tibet are assumed to be naturally unsuitable for forests. Yet, climatic conditions do allow for the growth of indigenous trees in Lhasa and

Growth, demography and carbon relations of Polylepis trees at the world's highest treeline

Growth, reproductive success and non-structural carbon pools in Polylepis tarapacana Philippi trees were examined across a transect between 4360 and 4810 m altitude on Nevado Sajama, Bolivia, suggesting a direct thermal limitation of tree growth.

Tropical moist Polylepis stands at the treeline in East Bolivia: the effect of elevation on stand microclimate, above- and below-ground structure, and regeneration

Both the marked change in carbon allocation towards the root system, as well as the changes in root morphology with elevation indicate an adaptation to reduced nutrient supply under cold conditions of these Polylepis stands at the treeline in E Bolivia.


Measurements of soil temperature, soil mois- The lack of dense, dwarfed tree stands above ture, and surface temperature were carried out the timberline seems to be a result of natural at different

A world‐wide study of high altitude treeline temperatures

Aim  At a coarse scale, the treelines of the world's mountains seem to follow a common isotherm, but the evidence for this has been indirect so far. Here we aim at underpinning this with facts.
