摘要本文描述了在捷克共和国苏马瓦国家公园的一个长期废弃的、部分退化的半天然山地牧场中，恢复0.7头牲畜.ha-1的季节性放牧对植被的影响。有非常不均匀的放牧强度内的地方，和放牧偏好的季节变化：牛吃草的大部分时间在生产，但物种贫乏Deschampsia cespitosa草地，但改变了物种丰富的Violion caninae站在夏季中期。一个物种丰富的长喙苔草社区只在本赛季结束时放牧。以狭叶草和苔草为主的贫种草地主要用作休息区。放牧和禁牧均对丛生发草草地物种多样性产生负面影响。土壤种子库中只有少数物种是山地草原群落的特点，和牛粪的目标物种的种子传播也被发现是非常有限的。因此，在这种情况下，放牧和排除放牧可能是有限的价值恢复物种丰富的草地从物种贫乏Deschampsia丛生草地。命名：Oberdofer（1977）为syntaxa; Rothmaler（1995）为taxa，除了Dactylorhiza majalis Reichenb。SSP. turfosa Procházka和早熟禾（Poa subcaerulea Smith）。
Abstract This paper describes the effects of re-establishing seasonal cattle grazing by 0.7 animal.ha−1 on vegetation in a long-term abandoned, and partly degraded, semi-natural mountain pasture in the Šumava National Park, Czech Republic. There was very uneven grazing intensity inside the locality, and grazing preference changed during the season: cattle grazed most of the time in productive but species-poor Deschampsia cespitosa swards, but changed to a species-rich Violion caninae stand in the middle of the summer. A species-rich Carex rostrata community was only grazed at the end of the season. Species-poor swards dominated by Nardus stricta and Carex brizoides were mainly used as resting areas. Both grazing and excluding from grazing had a negative effect on species diversity of the Deschampsia cespitosa swards. The soil seed bank contained only few species that are characteristic of mountain grassland communities, and seed dispersal of the target species by cattle dung was also found to be very limited. Thus both grazing and exclusion from grazing are probably of limited value for the restoration of species-rich grasslands from species-poor Deschampsia cespitosa swards in this case. Nomenclature: Oberdofer (1977) for syntaxa; Rothmaler (1995) for taxa, except for Dactylorhiza majalis Reichenb. ssp. turfosa Procházka and Poa subcaerulea Smith.
