Multifunctionality and Thresholds of Alpine Grassland on the Tibetan Plateau

Journal of Resources and Ecology, 2020
Ecosystems can simultaneously provide multiple functions and services. Knowledge on the combinations of such multi-dimensional functions is critical for accurately assessing the carrying capacity and implementing sustainable management. However, accurately quantify the multifunctionality of ecosystems remains challenging due to the dependence and close

The ecology of some alpine grasslands

1968
The study of the ecology of the alpine grasslands of New Zealand is in its infancy and one of the lesser-known kinds of grassland is that dominated by the short grass Chionochloa oreophila (Petrie) Zotov. This grass lives near the upper limit of alpine vegetation, usually in hollows where snow lies late into the summer (frontis-piece).

A 5‐year rotational grazing changes the botanical composition of sub‐alpine and alpine grasslands

Applied Vegetation Science, 2018
AbstractAimThe implementation of Grazing Management Plans (GMP), a specific policy and management tool, aimed at enhancing farm productivity while preserving plant diversity, soil and landscape. The GMP are based on rotational grazing systems (RGS) with animal stocking rate adjusted to balance grassland carrying capacity. The aim was to test the 5‐year

On community structure in high alpine grasslands

Vegetatio, 1989
Previously published data on production biology, energy use efficiency, nutrient availability and vulnerability were reinterpreted for the explanation of community processing and structure in high altitude grasslands of the Alps. The final goal of the approach was to present a characterization of these plant communities in generalized terms.

Floristic composition of an alpine grassland in Bandipora, Kashmir

Grassland Science, 2010
AbstractFloristic composition of a high‐altitude alpine grassland, located in Bandipora district of Indian administered Jammu and Kashmir, was investigated. The grassland comprises three broad zones (a) flat valley with only few habitat types, (b) lower slope, and (c) upper slope with diverse habitat types (numerous rock boulders, rock crevices and ...

Machine learning in soil nutrient dynamics of alpine grasslands

Science of The Total Environment
As a terrestrial ecosystem, alpine grasslands feature diverse vegetation types and play key roles in regulating water resources and carbon storage, thus shaping global climate. The dynamics of soil nutrients in this ecosystem, responding to regional climate change, directly impact primary productivity.

Quantitative ecological relationships in the alpine grassland of Lesotho

Proceedings of the Annual Congresses of the Grassland Society of Southern Africa, 1974
A survey, based on 56 000 points at 102 sampling sites in the Tsehlanyane valley of the Oxbow (Madibamatso) Dam catchment in the alpine grassland of Lesotho, indicates that the area is generally in good condition. Physiographic and floristic criteria were measured and the association between pairs of criteria statistically tested. The simple (126 spp.)

Analysing the potential of multispectral sensors to map vegetation parameters in pre-Alpine and Alpine grasslands

2018
Pastures and natural grasslands are an important part of the pre-Alpine and Alpine landscape ranging from intensive grasslands in the lower regions to highly diverse seasonal mountain pastures and specialized natural ecosystems. Despite the economic value and the significant role of plants in grassland carbon (C) and nitrogen (N) cycling, spatially ...

Challenges facing alpine/mountain grasslands

This chapter reviews the main characteristics of grasslands in mountain areas. The challenges for grassland farming are mainly related to topographic features and to productive and socioeconomical issues. These challenges strongly limit management options, which often leave grasslands as the only possible agricultural land use and livestock farming as ...

Grazing pressures of grasshoppers in an alpine tussock grassland

New Zealand Journal of Agricultural Research, 1974
Abstract Behavioural and environmental criteria were used to assess consumption and grazing pressures of a community of three grasshopper species in alpine tussock grassland in the Craigieburn Range, Canterbury, New Zealand. The total consumption of each species and sex was calculated for different age classes (instars) by relating ...
