Dissipation of Picloram from Vegetation of Semiarid Rangelands
Weed Science, 1971About 25 ppm of 4-amino-3,5,6-trichloropicolinic acid (picloram) usually were detected on grass, primarily buffalograss (Buchloe dactyloides(Nutt.) Engelm.) and blue grama (Bouteloua gracilisWilld.exHBK LagexGriffiths), immediately after application of 0.28 kg/ha picloram + 0.28 kg/ha (2,4,5-trichlorophenoxy)acetic acid (2,4,5-T) in northwest Texas ...

Rangeland vegetation — hydrologic interactions
1988Hydrologic 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 attributes and their application to the management of Australian rangelands
1988This 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 ...

Vegetation management of Chenopod rangelands in South Australia
The Rangeland Journal, 1984In 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.

Vegetation-soil relationships on arid and semiarid rangelands
1988Vegetation-soil relationships on rangelands, or any other lands must include all ecosystem components. That soil is a function of climate, organisms, topography, parent materials, and time establishes the basic model. Rangeland plant community distribution and species composition are known to be related to specific soil properties such as soil climate (

On the ground estimation of vegetation cover in Australian rangelands
International Journal of Remote Sensing, 1998A 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.

Climate-grazing interactions in Mongolian rangeland vegetation
2022Rangelands 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.

Interrill erosion and roughness parameters of vegetation in rangelands
CATENA, 2017Abstract In recent decades, the micro-region of Paraiba state, Brazil, has been undergoing the process of replacing its native coverage by crops, mainly pastures for grazing. This land use change has led to the detachment of soil due to the water erosion.

Evaluation and Determination of Rangeland Vegetation in Kayseri Province
2014Meralar hayvan varlığımızın temel beslenme kaynaklarından biridir. Buna ilaveten meralar, su kaynağı olmaları, biyoçeşitliliğe sahip bulunmaları ve rekreasyon alanı olarak değerlendirilmeleri açısından önemlidir. Mera alanlarının ıslahı ve yönetimi için mevcut durumun belirlenmesi gereklidir.
