Based on theories of ecological heritage, agricultural geography, and time geography, and applying landscape visual analysis, this study purports to investigate the transformation of a cattle grazing farm into pasture landscape during the past 100 years in Yangmingshan National Park. It intends to identify the general backgrounds, social needs, and economics of the farm in terms of the farm’s main functions, owner’s values, and maintenance factors, etc. for different time period. It also analyzes the current resources for and practicality of maintaining the herd of buffalos in the National Park for landscape purpose. In traditional society of Taiwan Water buffalo was the main livestock bred by all rural households. Before 1934, however, cattle consigning farms managed by professional herdsmen with special equipments had appeared in Yangmingshan area. Their task was to take care of the water buffalos for households in northern Taiwan during the slack period of the year. In 1934 the ruling Japanese government established “Talingka Cattle Farm” in this area as the first public owned but private operated business. The model has survived to this day. At its peak “Talingka Cattle Farm” was comprised of three sub-farms to handle 1,700 buffalos with pasture area totaling 1,000 hectors. Since 1960s, as results of declined agriculture industry and mechanization of farming, cattle rearing in Taiwan was a practice of the past. Yangmingshan National Park was established in 1985, and the cattle farm near Chingteingang in the Park has been kept. Buffalos and grass land in the farm have become the most frequented tour spot in Yangmingshan second only to Yangmin Park. After the pass of Pasturage Law in 1998, this area has been restricted to raising no more than 39 water buffalos, only a few of which now come from farm households as retired cattle. After the 2002 incident of tourist injury by a buffalo at Chingteingang, whether to keep the farm functioning has become a dilemma for the Taipei Farmers’ Association and Yangmingshan National Park. Henceforth, this study, after identifying “Chingteingang Landscape Cattle Farm” as a suitable ecological heritage of pasture, proposes the idea of establishing the “Water Buffalos Eco-Museum” to appeal for a sustainable ecological development of this pasturage.
