Modern pollen–vegetation relationships and human indicator taxa at high elevation human-impacted areas of the Bale Mountains, Ethiopia
Understanding the relationships between modern pollen assemblages and vegetation patterns is fundamental for reconstructing past landscapes and assessing anthropogenic impacts in ecologically sensitive high-altitude ecosystems. While previous studies in Ethiopia’s Bale Mountains explored paleo-reconstruction, quantitative approaches remain limited. This study quantifies pollen–vegetation relationships using transfer factors (TF), evaluates ecolog…
The new Garba Guracha palynological sequence
In the context of the DFG-funded project ‘Mountain Exile Hypothesis’ (FOR2358) we retrieved a 15.5 m long sediment core from Garba Guracha (GG) (Bale Mountains National Park, Ethiopia – BMNP) during February 2017. A 16,000 year record of 62 pollen samples has been previously produced from GG by Umer et al. (2007). In this data paper, we present a new palynological and macrocharcoal record, with 259 pollen and 1301 charcoal samples covering the la…

Ecological stability during the LGM and the mid-Holocene in the Alpine Steppes of Tibet?
Arid and Alpine ecosystems are known for extreme environmental changes during the Late Quaternary. We hypothesize that the world's largest Alpine arid ecosystem however, the Alpine Steppes of the Tibetan highlands, remained ecologically stable during the LGM and the mid-Holocene. This hypothesis is tested by distributional range of plant species, plant life forms and rate of endemism. The set of character species has a precipitation gradient betw…
Early human impact in the forest ecotone of southern High Asia (Hindu Kush, Himalaya)
The vegetation of the treeline ecotone of the southern declivity of arid High Asia (Hindu Kush, northern areas of Pakistan; Himalaya, northern central Nepal) is dominated by hedgehog-like open dwarf shrublands of thorny cushions. Since climatically sensitive ecotones are always also sensitive to human impact, the question arises whether the current lack of forests is a result of the Subboreal climate decline or of human impact. Due to inadequate …
Geo-ecological transect studies in northeast Tibet (Qinghai, China) reveal human-made mid- Holocene environmental changes in the upper Yellow River catchment changing forest to grassland
Author: Miehe, G. et al.; Genre: Journal Article; Finally published : 2008; Keywords: fire ecology, global change, China, Tibet; Title: Geo-ecological transect studies in northeast Tibet (Qinghai, China) reveal human-made mid- Holocene environmental changes in the upper Yellow River catchment changing forest to grassland
Status and Dynamics of the Kobresia pygmaea Ecosystem on the Tibetan Plateau
This paper provides information about the distribution, structure, and ecology of the world's largest alpine ecosystem, the Kobresia pygmaea pastures in the southeastern Tibetan plateau. The environmental importance of these Cyperaceae mats derives from the extremely firm turf, which protects large surfaces against erosion, including the headwaters of the Huang He, Yangtze, Mekong, Salween, and Brahmaputra. The emphasis of the present article is …
Highest Treeline in the Northern Hemisphere Found in Southern Tibet
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 …

Impact of Grazing Livestock and Distance from Water Source on Soil Fertility in Southern Mongolia
The impact of livestock grazing on soil nutrients and vegetation parameters was studied in dry montane steppes of southern Mongolia in order to assess the risk of habitat degradation. Data were collected along transects radiating away from permanent water sources. Dung unit density counts revealed gradients of livestock activity, but utilization belts around water sources overlapped, indicating that pastoral land use affects the entire landscape.…
Sacred Forests in Tibet
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 many parts of southern Tibet, even where there is no high groundwater table or irrigation. This was discovered and proven in a Sino–German research project launched in 1997. The project made an inventory of forest relics, correlated residual tree stands with cl…

The Significance of Fire for Afroalpine Ericaceous Vegetation
This paper presents results from studies in 4 mountain regions in East Africa, 2 in Ethiopia (Simen Mountains, Bale Mountains), and 2 in Uganda (Rwenzori Mountains, Mount Elgon). The focus is on the ericaceous vegetation that forms the (upper) treeline ecotone at all sites. There is little evidence for climatic control of the patchy appearance of this belt in all afroalpine environments. Since traces of former fires were observed in all ranges, r…

High Altitude Forests in the Jugal Himal (Eastern Central Nepal). Forest Types and Human Impact
Die Vegetationskarte der Khumbu Himal (Mt. Everest-Südabdachung) 1
The map was surveyed between August and November 1982 and drafted in the scale of 1: 25,000. The differentiation of vegetation units was undertaken by physiognomic criteria. The vegetation of the cloud forest belt is quasinatural on the shady slopes (Betula utilis and evergreen Rhododendron-woodlands) and mostly anthropogenic on the sunny slopes, which are widely used for winter grazing, because here the snow melts within a few days, whereas the …
