大沼泽地国家公园

今天是美国湿地月的最后一天，但对湿地生态的关注并不应随之结束。每年 5 月举行的这一全国性活动，旨在让更多人了解湿地这一美国最具生产力的重要生态系统之一。而位于佛罗里达州的大沼泽地国家公园，正是展现湿地力量的典型代表。从空中俯瞰，浅水、锯齿草、红树林与蜿蜒水道共同构成广阔景观，淡水从奥基乔比湖缓缓向南流动，塑造出独特生态环境。

大沼泽地国家公园面积约达 150 万英亩，是美国最大的亚热带荒野地区之一，也是众多鸟类、鱼类、爬行动物以及佛罗里达美洲狮等珍稀物种的重要栖息地。除了维持生物多样性，湿地还在生态系统中发挥着关键作用，例如过滤污染物、储存碳、减缓洪水，并为周边社区提供更洁净的水源。美国湿地月也提醒人们，无论从空中还是地面观察，这些水域景观都值得长期保护与关注。

End of American Wetlands Month

Today is the last day of American Wetlands Month, but don't let that bog you down. Take today to shine a spotlight on wetlands. Held throughout May, this national observance shines a spotlight on wetlands—some of the most productive ecosystems in the United States—and few places show their power quite like Everglades National Park. From above, Florida's iconic wetlands unfold as a vast patchwork of shallow water, sawgrass, mangroves, and winding channels, shaped by freshwater slowly flowing south from Lake Okeechobee.

Covering about 1.5 million acres, the Everglades is the largest subtropical wilderness in the country and a vital refuge for birds, fish, reptiles, and rare species such as the Florida panther. Wetlands also work behind the scenes, filtering pollutants, storing carbon, reducing floods, and helping supply clean water to nearby communities.

American Wetlands Month invites us to appreciate these watery landscapes—from above and on the ground—and recognize why protecting them matters long after May ends.

向树木致敬 A tribute to trees

大沼泽地松林

植树节旨在颂扬树木的无声力量——它们如何稳定生态系统、庇护野生动物、为城市降温，并塑造我们日常生活所依赖的环境。在美国，植树节定于四月的最后一个星期五，这一天鼓励美国以及许多其他国家（日期因生长季节而异）的社区种植、保护和养护各种类型的森林，从社区绿荫到标志性的荒野。

在佛罗里达州的大沼泽地国家公园（联合国教科文组织世界遗产地），高地松林耸立于沼泽和草原之上，共同构成了世界上最大的湿地系统之一。图中可见，阳光普照的火炬松和锯棕榈营造出开阔的林地，与大沼泽地广袤的湿地和红树林形成鲜明对比。在植树节这一天，这样的景观清晰地提醒着我们，树木对于这片非凡的亚热带生态系统的健康和平衡是多么重要。

Arbor Day

Arbor Day celebrates the quiet power of trees—the way they steady ecosystems, shelter wildlife, cool cities, and shape the environments we rely on every day. Observed in the United States on the last Friday in April, the day encourages communities here—and in many other countries, where dates vary according to growing season—to plant, protect, and care for forests of every kind, from neighborhood canopies to iconic wildlands.

In Florida's Everglades National Park, a UNESCO World Heritage Site, elevated pinelands rise above the marshes and prairies that form one of the world's largest wetland systems. Seen here, sunlit slash pines and saw palmetto create open woodlands that contrast sharply with the Everglades' vast wetlands and mangrove forests. On Arbor Day, landscapes like this offer a clear reminder of how essential trees are to the health and balance of this remarkable subtropical ecosystem.

佛罗里达州的生命湿地 Florida's living wetlands

庆祝大沼泽地国家公园成立78周年

在美国的最南端，延展着一片与众不同的自然奇景：大沼泽地。它既不是典型的沼泽，也不是河流，而是一片缓慢流动、浅而宽广的水域，从平坦的草原向南漂移，最终注入佛罗里达湾，它将森林、湿地、红树林与沿海草原连成一个庞大而复杂的亚热带生态网络。栖息着包括短吻鳄、海牛及濒危的佛罗里达美洲狮在内的数百种生物。1947年12月6日，美国设立了大沼泽地国家公园，保护面积超过150万英亩，并首次将保护重点从单一地标转向整体生态系统的保育。

如今日图片所示，蜘蛛网在芦苇间轻盈铺展，细丝在阳光下折射出细碎的光影。如今，大沼泽地已被列入联合国教科文组织世界遗产名录，然而它的生态平衡依旧脆弱：污染、城市开发以及水流改造，持续威胁着这片土地的生机。包括《大沼泽地综合修复计划》在内的重大生态项目，正致力于恢复自然水流、减少污染并限制城市扩张。在这片由湿地与水道交织的生态拼图中，生活着超过 350 种鸟类；美洲鳄与短吻鳄共栖同一片水域；佛罗里达美洲狮则在寂静的走廊间穿行。大沼泽地是一片仍在呼吸的土地。它提醒我们，保护自然，并非让生命静止，而是让它继续流动。

Celebrating 78 years of Everglades National Park

On Florida's southern tip lies one of the United States' most unusual landscapes. The Everglades is not a typical swamp or river. It is a slow, shallow sheet of water that drifts south across flat grasslands toward Florida Bay, linking forests, marshes, mangroves, and coastal prairies. This subtropical wilderness supports hundreds of species, including alligators, manatees, and the endangered Florida panther. On December 6, 1947, the United States established the Everglades National Park, protecting over 1.5 million acres and shifting conservation toward preserving entire ecosystems rather than isolated landmarks.

Spider webs stretch between reeds, catching light in fine reflections in the image featured today. The park is now a UNESCO World Heritage Site, yet its balance remains fragile: pollution, development, and altered water flow still threaten its habitats. Major restoration efforts, including the Comprehensive Everglades Restoration Plan, aim to restore natural water patterns, reduce pollution, and limit urban expansion. Within this mosaic, over 350 bird species live, both American crocodiles and alligators share its waters, and panthers move through its quiet corridors. The Everglades endures as a working landscape, proof that protection means letting life keep moving.

海岸的密码 

国家灯塔日

在GPS尚未为船只导航之前，灯塔就是航海者的重要领航标。每座灯塔都拥有独特的闪光模式，即使在漆黑的夜晚，水手们也能凭此确定自身所处的位置。今天是美国国家灯塔日，正是向这些沿海守护者致敬的良机。1789年，美国国会通过法案，规定所有灯塔由联邦政府统一维护。不论你是历史爱好者、海岸探险者，还是单纯钟爱经典工程建筑的人，这一天都值得你去深入了解灯塔的故事，或与亲朋好友一同参观灯塔。

如同世界上许多灯塔一样，佛罗里达州的加斯帕里拉岛灯塔至今仍屹立于海岸。今日图片中所示的加斯帕里拉岛后方灯塔，有着一段曲折的历史。它最初在特拉华州组装，1927年迁至此地。然而在2014年，这座灯塔被美国海岸警卫队废弃。所幸，这座灯塔在2017年经过修复，2018年再次点亮。如今，它每六秒闪烁一次白光。这两座灯塔均已被列入美国国家史迹名录。灯塔周边区域及其博物馆在特定季节对外开放，向人们讲述这片海域的航运历史。

National Lighthouse Day

Before GPS told ships where to go, lighthouses lit the way—each with its own flash pattern so sailors could figure out where they were, even in total darkness. It's National Lighthouse Day, a perfect excuse to give these coastal workhorses some credit. In 1789, Congress passed a law to make sure all lighthouses were taken care of by the federal government. Whether you're a history buff, coastal explorer, or just into old engineering, today is a great day to learn more about lighthouses or visit one with your friends and family.

Like many lighthouses around the world, Florida's Gasparilla Island Lights still hold their ground. The Gasparilla Island Rear Range Light, seen in today's image, has had quite a journey. Originally assembled in Delaware, it found its forever home here in 1927 but was decommissioned by the Coast Guard in 2014. The lighthouse was restored to its former glory in 2017 and was switched on again in 2018. Today, it blinks white every six seconds. Both lights are listed on the National Register of Historic Places. The lighthouse grounds and museum are open to visitors seasonally, offering insights into the area's shipping past.

彩虹河的清澈拥抱 The clear embrace of Rainbow River

彩虹泉州立公园的彩虹河，佛罗里达州，美国

坐落于佛罗里达州北部墨西哥湾沿岸的，是彩虹泉州立公园。数百年来，这片区域一直作为自然资源，为人类与动物所依赖。穿越公园蜿蜒流淌的彩虹河，正是其中的关键生态要素。河水源自佛罗里达州最大型的泉水之一彩虹泉，其水体汇集自770平方英里的广阔集水区，最终流入威特拉库奇河。

彩虹河清澈见底，全年水温恒定在72华氏度，非常适合游泳与浮潜。公园的历史可以追溯到19世纪80年代末，当时在该地区发现了硬岩磷矿，掀起了一场短暂而热烈的繁荣时期。受磷矿开采推动，一个名为朱丽叶的小型社区迅速在泉水周边发展起来。进入20世纪60年代，该地区逐渐转型为旅游胜地，推出了玻璃底船、单轨列车系统，甚至还有马术表演等游客娱乐项目。如今，游客可以探访这里的观赏花园、瀑布和步道，并近距离观察栖息于此的丰富野生动植物群落，感受这片水域的魅力。

Rainbow River, Rainbow Springs State Park, Florida

Nestled in the northern Gulf Coast of Florida, is Rainbow Springs State Park. This area has served as a natural resource for humans and animals for centuries, with the Rainbow River—flowing through the park—playing a major role. The gently winding waterway is fed by Rainbow Springs, one of Florida's largest springs. The water that bubbles up here comes from a 770-square-mile area and eventually flows into the Withlacoochee River.

The Rainbow River's transparent waters are perfect for swimming and snorkeling, and they maintain a constant temperature of 72°F year-round. The park's history dates to the late 1880s, when hard rock phosphate was discovered in the area, leading to a boomtown era. This period saw the rapid growth of a small community called Juliette near the springs, driven by the phosphate mining industry. During the 1960s, the park emerged as a popular tourist destination, featuring glass-bottom boat rides, a monorail system, and even a rodeo. Today, visitors can explore the ornamental gardens, waterfalls, and walking paths, and enjoy the diverse wildlife that calls Rainbow Springs home.

大沼泽地国家公园，佛罗里达州

我们是否曾设想，从高空俯瞰自身在这片广袤水域中的倒影？佛罗里达州的大沼泽地国家公园是美国最大的热带荒野，面积超过150万英亩。它保护了原始大沼泽地的南部20%，栖息着众多珍稀和濒危物种，包括佛罗里达美洲豹、美洲鳄以及西印度海牛。大沼泽地国家公园被称为“草之河”，其独特的生态系统由从奥基乔比湖缓慢流向佛罗里达湾的河流供养，是热带涉禽的重要繁殖地。这座国家公园不仅是美国的自然瑰宝，也具有重要的国际价值。它被联合国教科文组织列为世界遗产、国际生物圈保护区以及国际重要湿地。

大沼泽地公园在水资源保护与防洪调蓄方面也发挥着至关重要的作用，其湿地系统如同天然过滤器，同时也是抵御风暴侵袭的重要缓冲区。当前，针对大沼泽地的保护与生态修复工作仍在持续推进，涵盖多个方面，包括应对入侵物种、改善水质及保护野生动物栖息地等关键举措。

Everglades National Park, Florida

Wouldn't it be great to see our reflection from above in this vast expanse of water? Everglades National Park, located in Florida, is the largest tropical wilderness in the US, spanning more than 1.5 million acres. It protects the southern 20% of the original Everglades and is home to numerous rare and endangered species, including the Florida panther, American crocodile, and West Indian manatee. Often referred to as the 'River of Grass,' the park's unique ecosystem, fed by a slow-moving river from Lake Okeechobee to Florida Bay, is a significant breeding ground for tropical wading birds. Everglades National Park is not only a national treasure but also an international one, recognized as a World Heritage Site, an International Biosphere Reserve, and a Wetland of International Importance.

The park also plays a crucial role in water conservation and flood control, as its wetlands serve as natural filters and buffers against storms. Efforts to preserve and restore the Everglades are ongoing, with numerous initiatives aimed at combating invasive species, improving water quality, and protecting wildlife habitats.

欢迎来到大沼泽地 'Everglad' to be here

大沼泽地国家公园

90年前的今天，美国通过了一项法案，一个自然瑰宝也由此诞生：大沼泽地国家公园。这个位于佛罗里达州的公园囊括了美国最大的亚热带荒野。它占地150多万英亩，园区里生活着36种受联邦保护以及濒危的野生动物，如温顺的海牛、神秘的佛罗里达美洲豹。在这里，空气中回荡着350多种鸟类的叫声，如秧鹤、食螺鸢，水域中也是生机勃勃，有各种各样的鱼类，如锯盖鱼、红鱼，还有美洲鳄的身影。除了生物多样性之外，该公园还赢得了全球的认可，被联合国教科文组织评为世界遗产、国际生物圈保护区和国际重要湿地。因此，让我们向大沼泽地国家公园致敬！愿它可以继续为我们带来惊喜，并激发我们的好奇心以及欣赏周围野生世界的兴趣。

Everglades National Park marks 90 years

On this day 90 years ago, Congress passed an act that would lead to the creation of one of America's natural gems: Everglades National Park in Florida. It would be another 13 years before enough land was acquired to make the park a reality, but today it encapsulates the largest subtropical wilderness in the US. Spanning more than 1.5 million acres, the park is a lifeline to 36 federally protected and endangered wildlife species, from the gentle manatee to the stealthy Florida panther. Here, the air thrums with the calls of over 350 bird species like limpkins and snail kites, while the waters teem with life including hundreds of species of fish, sea turtles, and American crocodiles. Beyond its biodiversity, the park is celebrated as a UNESCO World Heritage Site, an International Biosphere Reserve, and a Wetland of International Importance. Here's to Everglades National Park—may it continue to inspire wonder, curiosity, and appreciation for the wild world around us.

七英里大桥，佛罗里达州，美国

很久很久以前，佛罗里达州住着一位富有的实业家，名叫亨利·弗拉格勒。他启动了一项艰巨的工程：修建一条连接佛罗里达大陆和基韦斯特的跨海铁路。最终，七英里桥于1912年正式落成，被称为世界第八大奇迹。然而，奇迹并不长久，1935年，这座大桥遭遇飓风从而停止了运营。后来，这座桥被卖给了美国政府，经历重建后摇身一变，成了一条汽车高速公路，于1938年重新开放。

如今，你若到访这座久负盛名的七英里桥，你会发现两座桥：一座是老七英里桥，仅对行人和骑自行车的人开放，另一座是于1982年建成的新七英里桥，用于车辆通行。好莱坞大片《杀人执照》和《真实的谎言》中都曾出现过这座桥的身影。

Overseas Highway, Florida Keys

Once upon a time, there lived a wealthy industrialist, Henry Flagler, who embarked on the herculean task of creating an overseas railway connecting mainland Florida to Key West. When it opened in 1912, it was dubbed the Eighth Wonder of the World. However, the triumph was short-lived. It was hit by a hurricane on Labor Day, 1935 and the railroad discontinued operations. The railway was sold to the US government and rebuilt as an automobile highway, opening in 1938.

These days, the Overseas Highway still stretches about 113 miles through the Florida Keys over 42 bridges, which jump from island to island over the Atlantic Ocean, Florida Bay, and the Gulf of Mexico. Many of the original bridges were replaced in 1982, including the longest, the Seven Mile Bridge pictured in the distance in our homepage image. Drivers crossing the Overseas Highway can still see remnants of some of the old bridges running alongside their replacements, including the Old Seven Mile Bridge, a section of which was renovated for cyclists and pedestrians. An engineering marvel, the ‘highway that goes to sea' has also featured in blockbusters like 'License to Kill' and 'True Lies.'

在一棵秃柏树上吊床露营，佛罗里达州

传统的吊床是由中美洲人发明的，最初是用来在睡觉时保护自己免受危险的昆虫和动物的袭击。如今，吊床是一个用来增添乐趣的工具。由布料、网或绳子等各种各样的材料制作而成的吊床，是旅行者最好的伙伴。在佛罗里达州，秃柏树就是一个挂吊床的绝佳去处。

National Hammock Day

It’s National Hammock Day! A day to slowly unwind while rocking gently from side to side. These days, hammocks are associated with summer relaxation, but they were originally developed by Central Americans to protect them from dangerous insects and animals. Today the hammock is a traveler's best buddy, made from a variety of materials like fabric, netting, or rope. But where best to hang it? Florida boasts some beautiful hammock hang-out spots, like the bald cypress tree pictured on our homepage. Have hammock, will travel and relax. It's just that simple.
