卡纳蓝蝴蝶已从印第安纳沙丘国家公园消失,成为第一个因气候变化而从美国国家公园消失的已知物种。像布伦南一样,全国各地的公园管理员亲眼目睹了气候变化的破坏性影响,包括气温上升、天气模式变化和物种入侵。尽管人们为拯救冰川国家公园的白皮松等物种做出了勇敢的努力,但随着气候危机的加剧,预后仍然不确定,公园管理员们不得不面对他们对这些脆弱生态系统的影响力日益减弱的严酷现实。
Climate Crisis Devastates National Park Ecosystems: Karner Blue Butterfly Vanishes, Glacier's Whitebark Pines Face Extinction
气候危机破坏国家公园生态系统:卡纳蓝蝴蝶消失,冰川白皮松面临灭绝
The ongoing climate crisis is leaving an indelible mark on the pristine landscapes of America's national parks, as rising temperatures and other stressors wreak havoc on delicate ecosystems. One tragic example is the disappearance of the once-abundant Karner blue butterfly from Indiana Dunes National Park, becoming the first known endangered species to be lost from an American national park solely due to global warming.
随着气温上升和其他压力因素对脆弱的生态系统造成严重破坏,持续的气候危机正在美国国家公园的原始景观上留下不可磨灭的印记。一个悲惨的例子是,曾经数量众多的卡纳蓝蝴蝶从印第安纳沙丘国家公园消失,成为第一个仅因全球变暖而从美国国家公园消失的已知濒危物种。
Brennan, the park's former chief of natural resources, shared the heartbreaking news with AFP: "The Karner blue butterfly is now believed to have disappeared entirely from the midwestern US park, a victim of rising temperatures fueled by human activity, among other stressors."
该公园前自然资源主管布伦南向法新社分享了这一令人心碎的消息:“据信卡纳蓝蝴蝶已经从美国中西部公园完全消失,成为人类活动等压力因素导致气温上升的受害者。”
The loss of this beloved butterfly, while devastating, underscores the fragility of these intertwined ecosystems and the interconnectedness of all living organisms. "It's terrifying to know how fragile these systems are, and how interconnected everything is, and how little control we have," Brennan lamented.
这种心爱的蝴蝶的消失虽然具有毁灭性,但也凸显了这些相互交织的生态系统的脆弱性以及所有生物体的相互关联性。布伦南感叹道:“知道这些系统是多么脆弱,一切是多么相互关联,以及我们的控制力是多么少,真是令人恐惧。”
John Gross, of the National Park Service (NPS) climate change response program, echoed Brennan's sentiments, describing the emotional toll the crisis impacts take on park rangers. "Witnessing the crisis impacts is hugely emotional... It's not a career for many people. It's a way of life," he explained.
国家公园管理局 (NPS) 气候变化应对计划的约翰·格罗斯 (John Gross) 呼应了布伦南的观点,描述了危机影响对公园管理员造成的情感损失。 “目睹危机的影响令人非常激动……对许多人来说,这不是一种职业。这是一种生活方式,”他解释道。
Despite the grim reality, hope flickers in the resilience and dedication of park staff, like Dawn LaFleur, a biologist and vegetation program manager at Glacier National Park. LaFleur is tirelessly working to save an at-risk pine species, the whitebark pine, from extinction.
尽管现实严峻,但在公园工作人员的坚韧和奉献精神中,希望依然渺茫,比如冰川国家公园的生物学家兼植被项目经理道恩·拉弗勒尔 (Dawn LaFleur)。拉弗勒尔正在不懈地努力拯救濒临灭绝的松树品种——白皮松。
"Pretty much everything we do is in light of climate change," LaFleur told AFP. While some battles may seem winnable, others have already been lost. The Karner blue butterfly's disappearance serves as a stark reminder of the urgency to mitigate the impacts of climate change.
拉弗勒尔告诉法新社:“我们所做的几乎所有事情都是为了应对气候变化。”虽然有些战斗看似可以获胜,但其他战斗却已经失败。卡纳蓝蝴蝶的消失清楚地提醒人们缓解气候变化影响的紧迫性。
Strenuous efforts to restore the butterfly's habitat proved futile, highlighting the need for accelerated action to build resilience against climate change. "We need models and research on how to make lands more resilient against climate change... We need the ability to remove those stressors faster," Brennan emphasized.
事实证明,恢复蝴蝶栖息地的艰苦努力是徒劳的,这凸显出需要加快行动,增强抵御气候变化的能力。布伦南强调:“我们需要模型和研究如何使土地更能抵御气候变化……我们需要更快地消除这些压力源的能力。”
In Glacier National Park, the whitebark pine faces a dual threat from an invasive fungus and drought caused by early snowmelts and changing weather patterns. The dwindling pine population not only provides sustenance for wildlife, including grizzly bears and Clark's nutcrackers, but also plays a critical role in maintaining the park's ecosystem.
在冰川国家公园,白皮松面临着入侵真菌和早期融雪和天气模式变化引起的干旱的双重威胁。日益减少的松树数量不仅为灰熊和克拉克胡桃夹子等野生动物提供了食物,而且在维护公园的生态系统方面也发挥着关键作用。
For over two decades, thousands of whitebark pines have been laboriously replanted in Glacier National Park, despite the challenging mountainous terrain. "The more we spend in these environments, we realize how fragile they are in terms of the changes being wrought by climate change," LaFleur reflected.
二十多年来,尽管山区地形充满挑战,但冰川国家公园仍费力地重新种植了数千棵白皮松。拉弗勒尔反思道:“我们在这些环境上花费的钱越多,我们就会意识到它们在气候变化造成的变化方面是多么脆弱。”
Despite the overwhelming challenges, LaFleur remains steadfast in her hope to save the pines. "We can't change how hot and dry it gets in the summer now, for extended periods of time, we can't control that," she said with a resolute tone. "So it's more coming up with solutions to be able to adapt and direct our resources... to be able to really address what things we have control over and make a difference that way."
尽管面临巨大的挑战,拉弗勒尔仍然坚定地希望拯救松树。 “我们无法改变现在夏天的炎热和干燥程度,在很长一段时间内,我们无法控制它,”她语气坚决地说。 “因此,更多的是提出能够适应和指导我们的资源的解决方案......能够真正解决我们可以控制的事情并以这种方式产生影响。”
The plight of the Karner blue butterfly and the whitebark pine in Glacier National Park serve as a stark wake-up call, highlighting the urgent need to address the climate crisis and protect the delicate balance of our natural world for future generations.
冰川国家公园卡纳蓝蝴蝶和白皮松的困境敲响了警钟,凸显了解决气候危机和为子孙后代保护自然世界微妙平衡的迫切需要。
