Rangeland vegetation as wildlife habitat

1988
Managing rangelands as wildlife habitat requires knowledge of both plant ecology and wildlife biology. A common understanding of principles fundamental to both disciplines is also necessary. Furthermore, it should be recognized that vegetation, and wildlife habitat values, can change daily, seasonally, annually, and over longer periods of time.

Relationship Between Pastoralists’ Evaluation of Rangeland State and Vegetation Threshold Changes in Mongolian Rangelands

Environmental Management, 2014
Applying the threshold concept to rangeland management is an important challenge in semi-arid and arid regions. Threshold recognition and prediction is necessary to enable local pastoralists to prevent the occurrence of an undesirable state that would result from unsustainable grazing pressure, but this requires a better understanding of the ...

Tundra vegetation as a rangeland resource

1988
Tundra rangelands comprise about 10% of the earth’s land surface. They provide forage all or part of the year for millions of wild and domestic reindeer and for muskoxen as well as summer range for other domestic ungulates. Arctic tundra habitats are of international significance because of their importance to waterfowl and other migratory bird species.

Remote sensing applications for monitoring rangeland vegetation

Journal of the Grassland Society of Southern Africa, 1991
Remote sensing techniques hold considerable promise for the inventory and monitoring of natural resources on rangelands. A significant lack of information concerning basic spectral characteristics of range vegetation and soils has resulted in a lack of rangeland applications. The parameters of interest for range condition must be identified and a

Climate-grazing interactions in Mongolian rangeland vegetation

2022
Rangelands are the most widespread land-use systems in drylands, where they often represent the only sustainable form of land-use due to the limited water availability. The intensity of the land-use of such rangeland ecosystems in drylands depends to a large extent on the climatic variability in time and space.

Rangeland vegetation — hydrologic interactions

1988
Hydrologic resources are closely tied to an area’s climate and rangelands encompass many different climatic zones. Approximately 40% of the world’s land surface is classified as rangeland, and more than 80% is within arid and semiarid zones. Hydrologic processes are influenced greatly by the kinds and amounts of plants growing on rangelands.

Vegetation management of Chenopod rangelands in South Australia

The Rangeland Journal, 1984
In 1896 the leading South Australian pastoralist Peter Waite specified how the grazing of sheep on chenopod shrublands in South Australia should, in his opinion, be managed. In 1919 George Nicolson put most of Waite's specification into practice on Roopena station near Whyalla, South Australia.

Rangeland vegetation productivity and biomass

1988
Herbage weight or biomass is an important characteristic for range vegetation since it supports directly or indirectly all consumer groups. Plant biomass is also important as a measure of dominance in plant communities. Many methods have been devised to estimate plant biomass, but all have some limitations.

On the ground estimation of vegetation cover in Australian rangelands

International Journal of Remote Sensing, 1998
A number of field techniques were assessed on their reliability for estimating vegetation cover in Australian rangelands. The field sampling was undertaken using visual estimation, line intercepts, a crown cover model, and images acquired from a digital camera. The results from these methods were compared and analysed.

Vegetation attributes and their application to the management of Australian rangelands

1988
This chapter presents the attributes of species and communities in Australian rangelands and describes how these may be used to manipulate vegetation composition towards desired objectives. The characteristics of ephemerals, herbaceous perennials and woody perennials are outlined, including the flux of their populations in relation to variation in ...
