在私人土地内留出保护区可能是加强生物多样性友好景观的关键。这种保护战略在公共土地保护不力的高度受威胁地区,如巴西塞拉多,应该特别有效。巴西的《原生植被保护法》将保留区纳入了私人财产范围,但尚未对其与保护的相关性进行评估。我们评估私人土地是否有助于塞拉多的生物多样性,塞拉多是全球生物多样性保护的优先事项和粮食生产的主要地区,土地使用冲突往往与保护目标不一致。我们确定,私人保护区容纳了14.5%的受威胁的脊椎动物物种范围,这增加到25%时,考虑到剩余的原生栖息地的分布。此外,私人保护区的空间扩展使大量物种受益。私人保护地的生态恢复将提高这一保护系统的效益,特别是在塞拉多东南部,那里是一个大型经济中心,面临着热点威胁。
Areas set aside for conservation within private lands may be key to enhancing biodiversity-friendly landscapes. This conservation strategy should be especially effective in highly threatened regions that are poorly protected by public lands, such as the Brazilian Cerrado. Brazil’s Native Vegetation Protection Law has included set-aside areas within private properties, but their relevance to conservation has not been evaluated. We assess whether private lands are contributing to biodiversity in the Cerrado, a global biodiversity conservation priority and major region for food production, where land use conflicts are often at odds with conservation objectives. We determined that private protected areas accommodate up to 14.5% of threatened vertebrate species ranges, which increases to 25% when considering the distribution of remaining native habitat. Moreover, the spatial spread of private protected areas benefits a large number of species. Ecological restoration of private protected lands would improve the benefits of this protection system, especially in the Southeastern Cerrado, where a large economic hub meets a threat hotspot.
