Digital charting technique for monitoring rangeland vegetation cover at local scale.

摘要: Changes in agro-pastoral production systems affect the livelihoods and development of rural communities. Thus it is important for planners policy makers to be able document land or ecosystem conditions trends relation managerial actions at specific locations. Quantification parameters that are used condition trend assessment has been difficult, time consuming expensive resulting very few locations worldwide with detailed records. We report monitoring techniques can local scales, speed up collection, processing storage indicators agroecosystem health. By coupling digital photography, differential global positioning technologies, information collected accessory devices computer software applied a strict protocol enabled rapid sampling recording geographic position (latitude/longitude) quadrates (1 25 m) vegetation, litter soil parameters. If vegetative species visually distinctive, plants also identified. Repeated measurements over same provide regarding environmental rate change. Coupling our scale landscape remote sensing data such as satellite high altitude aerial we have complete picture vegetation dynamics system change, which facilitates interpretation. © 2010 Friends Science Publishers
