Studies on the function and role of grazing domestic animals in the semi-mountainous regions of Kyushu

2002年，利用GPS对森林中的土地利用和放牧行为进行了监测。这些动物在山上的休息区和低地的饮水点之间移动时吃草。它们每天分别花10%、40%和50%的时间移动、放牧和其他活动。芒草是最受欢迎的植物。2003年，移动饮水点被证明对改变牛的家庭范围是有效的。放牧使林下生物量减少50 ~ 70%，在林下控制中具有较大的节约人力的优势。虽然承载能力在3年内保持较高水平，但建议在放牧季节结束时将动物避开的植物移走。确保高水平的承载能力。随着放牧年限的增加，常绿乔木增加，落叶乔木和草本植物减少。这主要归因于动物对植物选择性的动态变化。对宫崎县Morotsuka村的立地分析表明，大部分木材生产区适合于森林牧区。放牧林内溪水硝酸盐氮浓度虽高于非放牧林内，但远低于自来水（人类饮用）标准。蜈蚣草是一种很有发展前途的草本植物，在东坡上播种最好，在初夏播种，不受氮肥的影响。

In 2002, land use and behavior of cattle grazing in a forest were monitored using a GPS. The animals grazed during moving between a resting area on a hill and a drinking point in lowland. They spent 10, 40 and 50% of day moving, grazing and with other activities, respectively. Miscanthus sinensis was the most preferred plant. In 2003, moving the drinking point was shown to be effective in modifying the home range of cattle. Grazing decreased biomass of undergrowth by 50-70%, showing considerable labor-saving advantage in undergrowth control. Although carrying capacity remained high for 3 years, it was recommended that plants avoided by animals should be removed at the end of grazing season to. ensure a high level of carrying capacity. There was a trend of increasing evergreen trees and decreasing deciduous trees and herbaceous plants with the progression of grazing years. which was mainly attributed to dynamics in plant selectivity by the animals. Site analysis of Morotsuka Village, Miyazaki Prefecture, showed a majority of timber-producing forest areas are suitable for the silvipastoral system. Although nitrate-nitrogen concentration of stream water in the grazing forest was higher than that in the non-grazing forest, the concentration was much lower than the standard for tap water (human drinking). Establishment and development of centipedegrass, a promising herbage species, were best on an eastern slope, with seeding by early summer, and were not affected by nitrogen fertilizer.
