摘要

Dinerstein等人为扭转灾难性生物多样性损失和稳定气候所需的保护区提出了一个空间明确的全球框架。安大略省(加拿大)在“全球安全网”中脱颖而出,成为实现这些目标的关键管辖区,因为该省拥有大量无路土地和陆地生态系统中的高碳储量。与此同时,在安大略省,特别是在遥远的北方,开发未经管理的土地用于资源开采的压力越来越大。在这里,我们从GSN中提取数据,以确定和计算安大略省目标区域的面积范围,并严格审查结果的准确性和对保护的影响。我们表明,当纳入特定地区的数据时,安大略省甚至比GSN中显示的更重要,尤其是在森林和开阔泥炭地的碳储量方面。此外,GSN中使用的生物多样性指标仅部分反映了安大略省的保护机会,官方承认的土著土地范围大大低估了原住民在保护中的作用。尽管存在这些局限性,但我们的分析表明,安大略省在影响全球生物多样性和气候轨迹方面发挥着巨大作用。

Safety Net Ontario: Ontario’s outsized role in the “Global Safety Net” for climate and biodiversity
Dinerstein et al. present a spatially explicit global framework for protected areas needed to reverse catastrophic biodiversity losses and stabilize climate. The Province of Ontario (Canada) stands out in this “Global Safety Net (GSN)” as a critical jurisdiction for meeting those goals, because of both the large extent of roadless lands and high carbon storage in terrestrial ecosystems. Simultaneously, pressure is increasing to develop unmanaged lands in Ontario, particularly in the Far North, for resource extraction. Here, we extract data from the GSN to identify and calculate the areal extent of target regions present in Ontario and critically review the results in terms of accuracy and implications for conservation. We show that when region-specific data are incorporated, Ontario is even more significant than what is shown in the GSN, especially in terms of carbon stocks in forested and open peatlands. Additionally, the biodiversity metrics used in the GSN only partially capture opportunities for conservation in Ontario, and the officially recognized extent of Indigenous lands vastly underestimates the role of First Nations in conservation. Despite these limitations, our analyses indicate that Ontario plays an outsized role in terms of its potential to impact the trajectories both of biodiversity and climate globally.
