守护美国瑰宝 Protecting America's treasures

红杉国家公园与州立公园

110年来，美国最杰出的户外课堂始终向人们开放，供大家探索。8月25日，美国国家公园管理局迎来其守护美国自然与文化瑰宝一个多世纪的纪念日。1916年，伍德罗·威尔逊总统签署《组织法》使其成为法律，该机构由此成立；如今，它负责管理全美数百座公园、纪念地、海滨和历史遗址。由护林员带领的项目、家庭活动和教育活动邀请游客亲近那些塑造了国家公园体系的景观与故事。

今天的图片展示了加利福尼亚州北部的红木国家与州立公园，阳光照亮了一条蜿蜒穿行于地球上一些最高树木之间的小径。高耸的海岸红杉矗立在由蕨类植物和苔藓组成的葱郁林下植被之上，营造出一片既古老又充满生机的森林。这些林地是一个支撑着多种野生动物和数百年古树的生态系统的一部分，展现了美国国家公园管理局世世代代协助保护的自然奇观，也让游客有机会漫步于这些活着的巨树之下，体验一片独一无二的景观。

Anniversary of National Park Service

For 110 years, America's greatest outdoor classroom has been open for exploration. On August 25, the National Park Service marks over a century of protecting the nation's natural and cultural treasures. Established in 1916 when President Woodrow Wilson signed the Organic Act into law, the agency now cares for hundreds of parks, monuments, seashores, and historic sites across the country. Ranger-led programs, family activities, and educational events invite visitors to connect with the landscapes and stories that define the national park system.

Today's image shows Redwood National and State Parks in northern California, where sunlight illuminates a trail winding among some of the tallest trees on Earth. Towering coast redwoods rise above a lush understory of ferns and mosses, creating a forest that feels both ancient and alive. Part of an ecosystem supporting diverse wildlife and centuries-old trees, these groves showcase the natural wonders the National Park Service has helped protect for generations, offering visitors the chance to walk beneath living giants and experience a landscape unlike any other.
