In this paper, we tested the use of active and passive sensor fusion for relating forest fire history to landscape spatial patterns. Principal Components Analysis (PCA) was implemented to combine Landsat Thematic Mapper (TM) and Shuttle Imaging Radar (SIR-C) data from October 1994. Resulting PCs were converted to landscape patch maps. Plots with known fire history were delineated using a fire a...

The USA has about 336 Mha of grazing lands of which rangelands account for 48%. Changes in rangeland soil C can occur in response to a wide range of management and environmental factors. Grazing, fire, and fertilization have been shown to affect soil C storage in rangelands, as has converting marginal croplands into grasslands. Carbon losses due to soil erosion can influence soil C storage on r...

The occurrence of short-interval, severe wildfires are increasing drastically at a global scale, and appear as novel phenomenon in areas where fire historically returns large time lapses. In forest ecosystems, these events induce drastic changes population dynamics, which could dramatically impact species diversity. Here, we studied the effect on diversity recent (SISF), occurred rapid successi...

Rangelands play a critical role in the global carbon cycle. However, the eco-physiological mechanisms associated with the effects of grazing on leaf photosynthesis and soil respiration remain poorly understood. To examine the impacts of grazing on leaf photosynthesis and soil respiration, we measured the photosynthetic parameters of the dominant species (Trifolium repens) and the soil respirati...

People in the rural, communal areas of South Africa rely on live fuel wood for more than 90% of their energy requirements. Using airborne lidar from the Carnegie Airborne Observatory (CAO) we compared tree canopy cover and height distributions between communal landscapes with heavy utilization to fully protected public and private reserves in the Lowveld of South Africa. Rangelands and fields i...

_______________________________________ The 11 papers in this document address issues and needs in the development and stewardship of Central Asia rangelands, and identify directions for future work. With its vast rangelands and numerous pastoral populations, Central Asia is a region of increasing importance to rangeland scientists, managers, and pastoral development specialists. Five of the pa...

The survival of the extensive livestock system, practice for most farmers in industry Ghana depends heavily on natural pastures as forage resource. To efficiently use rangelands, knowledge species composition, especially that poisonous plants is essential. Documented scanty; documentation and dissemination resource would enable a wider access benefit to stakeholders. A study was conducted with ...
