Grazing at near-natural stocking rates is increasingly rare, whereas abandonment and overgrazing is common, despite both leading to loss of threatened species. Here, we evaluate a biodiversity-promotion strategy of a beef-producing company involving livestock grazing for conservation. Using field surveys, a national biodiversity map, and farmer interviews, we evaluate the conservation potential of farmers committing to a conservation grazing scheme. Most farmers practiced summer grazing, and-contrary to their pledge-primarily grazed areas of low conservation value, and with stocking rates far above carrying capacity. We conclude that a conservation grazing beef brand will only have real value for threatened species if committed to, and held accountable to, a scientifically informed grazing scheme. Our results point to rural traditions, legal regulations, and economic incentives as factors obstructing of a beneficial grazing practice. Hence, the results of this study call for a critical and scientifically informed approach to future land-sharing policies.
以接近自然的载畜率放牧越来越罕见，而弃牧和过度放牧却很常见，尽管这两种情况都会导致濒危物种的减少。在此，我们评估了一家牛肉生产公司为促进生物多样性而实施的一项涉及为保护目的而进行牲畜放牧的策略。通过实地调查、国家生物多样性地图和农民访谈，我们评估了参与保护放牧计划的农民的保护潜力。大多数农民进行夏季放牧，并且与他们的承诺相反，他们主要在保护价值较低的地区放牧，且载畜率远远高于承载能力。我们得出结论，一个保护放牧牛肉品牌只有在致力于并对科学合理的放牧计划负责的情况下，才会对濒危物种具有真正的价值。我们的研究结果表明，农村传统、法律法规和经济激励措施是阻碍有益放牧实践的因素。因此，本研究结果呼吁对未来的土地共享政策采取批判性的、基于科学的方法。
