Herbaceous forage variability in an arid pastoral region of Kenya: importance of topographic and rainfall gradients.

摘要: Temporal and spatial variabilities in rainfall, herbaceous production biomass were studied over a 4-year period topographically diverse, arid pastoral region of northwest Kenya. A significant relation between rainfall primary was found, this applied manner that considered topographic variation its influence on the region. Primary responses to occurred as pulses rapidly attenuated dry seasons progressed. The combination temporal variability forage is for nomadic pastoralists who move along gradients wet seasons. Dry areas at low elevations produce available only short time, which explains use drier early season. Quantitative analyses relationships topography, are needed determine appropriate densities diverse regions.
