被人类遗忘的森林 Our forgotten forests

Mangrove Conservation Day

Although we think of forests as trees on land, some of the most important trees grow in water, or more precisely marshland. Mangrove forests, like this one in Saloum Delta National Park in Senegal, are vital components of the world's coastal ecosystems. Mangroves survive where no other trees can, in salty, low-oxygen coastal waters exposed to tides and storms. They grow up to 30 feet high primarily in tropical and subtropical regions and are able to store vast amounts of carbon, making them crucial to moderating our climate. Mangroves also act as nurseries for fish and aquatic life. And with their complex interwoven root system, they protect coastlines from erosion. Today we join the UN in shining a light on the necessity and fragility of mangroves: July 26 is the International Day for the Conservation of the Mangrove Ecosystem.

The Saloum Delta is part of a UNESCO World Heritage Site, and a sterling example of the biodiversity of marshlands. These shallow, brackish channels contain about 200 islands and islets and support all kinds of marine life and birds. Dolphins and caimans swim in its creeks. Monkeys, warthogs, buffaloes, rhinos, and giraffes roam the savanna farther inland. The park biosphere includes salt flats, estuaries, and of course mangrove forests. Humans have also long inhabited this delta, fishing its waters and cultivating shellfish from giant mounds. For as long as 2,500 years, people have flourished off the bounty of this delta, a bounty made possible by the sturdy mangrove, the bedrock for these marshes, and the keepers of our coastlines.

热带,陆地与海洋热情相拥 In the tropics, land greets sea warmly

International Day of the Tropics

Only in the tropics do forests grow in salt water. Take this forest of mangrove trees in Phang Nga Bay in southern Thailand, one of the largest and best preserved mangrove forests in the country. Adapted to thrive in coastal marshes and swamps, mangroves can filter saltwater and withstand strong coastal storms. Virtually all mangrove forests and all species of mangrove grow only in the tropical regions of the world. They are protectors of the coastlines, acting as a buffer against storms and floods.

Today and on every June 29, we join the United Nations in marking the International Day of the Tropics, a moment to focus on the unique beauty of this region of the world and the challenges it faces. The tropics are roughly defined as the area above and below the equator between the Tropic of Cancer and the Tropic of Capricorn. By 2050, the UN estimates the tropics will be home to most of the humans on Earth, and two-thirds of the world's children. It is also the poorest part of our world and the most vulnerable to global warming.

Phang Nga Bay on the Andaman Sea is one of the most treasured and visited sites in Thailand. The south-facing bay is about 150 square miles in size, and contains numerous limestone islets, tower karsts, cliffs, caves, and lagoons. At its mouth is the tourist mecca of Phuket island. Much of the bay is protected as the Ao Phang Nga National Park, created in 1981 by royal decree. The most famous landmark in the park is probably Ko Tapu, a tall cylindrical rock that is narrower at its base than at its top. It was featured in the 1974 James Bond movie 'The Man with the Golden Gun,' and has since been dubbed 'James Bond Island.' The real star of Phang Nga, however, is the mangrove. Resilient, wondrous, and beautiful, mangroves are an apt metaphor for the tropics they inhabit.




安达曼海上的攀牙湾是泰国最珍贵的景点之一。朝南的海湾面积约150平方英里,包含许多石灰岩小、塔式岩溶、悬崖洞穴和泻口是普吉岛的旅游圣地。该湾的大部分地区被保护为1981年根据皇家法令创建的敖攀牙国家公园公园中最著名的地标可能是Ko Tapu,这是一种高大的圆柱形岩石,底部比顶部窄。它曾出现在1974年詹姆斯·邦德的电影《金枪侠》中,后来被称为“詹姆斯·邦德岛”然而,攀牙岛真正的明星是红树林。红树林富有弹性、奇妙而美丽,是它们所居住热带的恰当隐喻

The 'dancing trees' of Sumba Island

On the northern coast of Indonesia's Sumba Island, a stand of mangrove trees appears to dip and sway to summon another dreamy sunrise. Walakiri Beach is gently sloped, so it's easy for a visitor to walk out into the knee-deep water to examine the extraordinary transitional zone of a mangrove ecosystem. Mangroves thrive here at the boundary between land and sea, growing in coastal salt water and low-oxygen conditions where other trees would quickly die. Their complex root systems filter out the salt and form a strong natural defense against storm surges, rising sea levels, and coastal erosion. Mangroves also create aquatic nursery habitats that support a highly diverse range of juvenile fish and crustaceans.

But despite their critical role in maintaining healthy oceans and coastlines, mangroves are disappearing fast, several times faster than forests on land. The United Nations estimates that the world has lost half its mangrove coverage in just the last 40 years. To raise awareness of the importance of mangrove ecosystems and to promote solutions for their sustainable management and conservation, the UN has declared that July 26 is International Day for the Conservation of the Mangrove Ecosystem. We'll dance to that.

How Quảng Ngãi got its grove back

Could these humble rows of trees prevent a natural disaster? The Vietnamese government hopes so. Mangrove forests like Bàu Cá Cái in coastal Vietnam's Quảng Ngãi Province are an important shield against destructive typhoons that rock the coast each year. Unfortunately, mangrove trees have been depleted over the years by population growth, climate change, and increased use of waters for fish farming. Plantings at Bàu Cá Cái—outlined by bamboo frames to create the neat patterns seen here—have been part of a major initiative to regenerate nearly 10,000 acres of mangrove forest around the country.
