For more than a century, the core mission of the National Park Service has been preserving the natural heritage of the United States. But now, as the planet warms, transforming ecosystems, the agency is conceding that its traditional goal of absolute conservation is no longer viable in many cases.
The service published an 80-page document that lays out new guidance for park managers in the era of climate change. The document, along with two peer-reviewed papers, is essentially a tool kit for the new world. It aims to help park ecologists and managers confront the fact that, increasingly, they must now actively choose what to save, what to shepherd through radical environmental transformation and what will vanish forever.
“The concept of things going back to some historical fixed condition is really just no longer tenable,” said Patty Glick, a senior scientist for climate adaptation at the National Wildlife Federation and one of the lead authors of the document.
The new research and guidance — which focus on how to plan for worst-case scenarios, decide what species and landscapes to prioritize, and how to assess the risk of relocating those that can’t survive otherwise — represent a kind of “reckoning” for the Park Service, Glick said.
For a profession long tied to maintaining historical precedents, the change is brutal, said Gregor W. Schuurman, a scientist with the climate change response program at the Park Service who helped to write the new guidance.
“It’s bargaining. Nobody wants to do this. We all got in this game, as the Park Service mission says, to ‘conserve unimpaired,’ ” Schuurman said. “But if you can’t do that in the way you thought, you have to see what you can do. There’s often more flexibility there than one imagines.”
The team behind the report kept a low profile during the Trump administration, when the Park Service was at the center of frequent political battles. The day before President Joe Biden’s inauguration, they began publishing their papers, which were years in the making.
The first one, titled “Resist, Accept, Direct,” aims to help park employees triage species and landscapes. In some cases, that will mean giving up long efforts to save them. The second outlines how to assess risks when relocating species. That may be crucial to saving plants and animals that can no longer survive in their natural habitat.
第一篇題為「抗拒，接受，指導」，旨在幫助國家公園職員依照物種和地貌的重要性分類。在某些情況下，那意味放棄長久以來拯救物種和地貌的努力。第二篇介紹如何評估重新安置物種的風險，這對拯救再也無法在天然棲地存活的動植物而言很關鍵。Source article: https://udn.com/news/story/6904/5512192
