Treasure Nature

Hi! Welcome to this humble blog. You may want to subscribe to TN's RSS feed for updates. Thanks! :D

As stated in Part 1 and Part 2, there are 34 regions through out the world with rich biodiversity as covered by BiodiversityHotspots.org. We have already tackled nine (9) for the Americas and twelve (12) for Africa, Europe, and Central Asia. The final installment will cover the Asia-Pacific region…

East Melanesian Islands (Bismarck and Admiralty Islands, the Solomon Islands, and the islands of Vanuatu). Excessive logging, mining, and unsustainable farming practices have accelerated habitat loss in these islands, threatening the survival of one of the most remarkable number of endemic species — 3,000 unique species of plants, shrubs, and trees. Faunal diversity isn’t far behind, led by the majestic Solomon  sea-eagle and more than a dozen threatened species of flying fox (large fruit-eating bats).

Himalaya (Northern Pakistan, Nepal, Bhutan and the Northwestern and Northeastern states of India). The hotspot is home to numerous large birds and mammals, including vultures, tigers, elephants, rhinos and wild water buffalo.

Indo-Burma (Eastern Bangladesh, Northeastern India, Myanmar, part of Yunnan Province in China, Laos, Cambodia, Vietnam, Thailand, and part of Peninsular Malaysia). Covering 2 million square kilometers (772,204.317 square miles) of tropical Asia, this immense treasure trove of biodiversity is yet to divulged a lot of secrets. Six large mammal species have been discovered in the last 12 years: the large-antlered muntjac, the Annamite muntjac, the grey-shanked douc, the Annamite striped rabbit, the leaf deer, and the saola. Bird life is also incredibly diverse, holding almost 1,300 different bird species. Sadly, these documented species and possibly a host of others still waiting to be discovered are in danger of being killed-off due to exploitation and habitat loss.

Japan. When we talk about this country, images of bullet-trains, cars, high rises, and other accouterments of modern technology usually comes to mind. However, the islands isolation has harbored Critically Endangered endemic species like the Okinawa woodpecker and the Japanese macaque (snow monkey). There are 46 endemic mammals.

Mountains of Southwest China (Southwest China and a tiny part of Myanmar). These mountains are host to different ecosystems, including the most endemic-rich temperate flora in the whole world. The golden monkey, giant panda, red panda, and a number of pheasants are among the threatened species endemic to this hotspot. Primary threats include Illegal hunting, overgrazing and firewood collection.

New Caledonia (Neighbor of Vanuatu). This small island (smallest of the hotspots) is home to five (5) endemic plant families, containing nearly 2/3 of the world’s Araucaria species, all endemic. Nickel mining, forest destruction, and invasive species threaten it’s biodiversity.

New Zealand. This country is home to a renarkable number of endemic species. None of its mammals, amphibians, or reptiles are found anywhere else in the world. In 700 years of colonization, 50 bird species have gone extinct.

Polynesia-Micronesia. 4,500 islands scattered across the Southern Pacific ocean, it is the epicenter of the Gloab extinction crisis. From the time Europeans arrived there 200 years ago, 25 bird species were eradicated from the face fo the Earth. The spectacular endemic honeycreepers and other forest birds of the Hawaiian Islands are among those that are seriously threatened but still surviving in this hotspot.

Southwest Australia. This hotspot is characterized by high endemism among plants and reptiles.The primary cause of habitat loss in the region has been agricultural expansion, aggravated by extensive fertilizer use. Introuced species like foxes and cats theathen the local fauna.

Sundaland (Southern Thailand, Malaysia, Singapore,  Brunei Darussalam, Western half of Indonesia, and the Nicobar Islands). Only one word can describe the biodiversity of this hotspot, spectacular. The better known of its fauna are all in danger of being wiped-out, led by the orangutang (man of the forest) and 2 species of Southeast Asain rhinoceros. Rubber plantations, oil palm plantations, and pulp production are 3 of the most threathening forces facing biodiversity in the Sundaland Hotspot.

Wallacea (central islands of Indonesia east of Java, Bali, and Borneo, and west of the province of New Guinea and Timor Leste). Flora and fauna species in this hotspot is so diverse, every island needs a Protected Area to safeguard its own species diversity. It is 2nd only to the Tropical Andes for bird endemism but also covers a relatively smaller area. It is threathend by a government-sponsored transmigration program, which aims to move people from urban areas into sparsely populated ones.

Western Ghats and Sri Lanka (the Ghats are in Southern India). The region harbors important populations of Asian elephants, Indian tigers, and the Endangered lion-tailed macaque. Sir Lanka is home to as many as 140 endemic species of amphibians. Freshwater fish endemism is extremely high, with over 140 native species. The region is  faced with a tremendous population pressure.

The Philippines. This archipelago of more than 7,000 islands is acknowledge as one of the word’s most biologically diverse countries. There are 6,000 plant and numerous animal species. Detailing the threatened and endangered species found in this country will take up one long article. Ironically, it is also one the most endangered hotspots with logging, farming, and population growth relentlessly pushing countless species to the verge of extinction.

So that’s 34 remaining biodiversity hotspots. Thirty-four regions of the Earth where most living species of this planet are concentrated. Will that number decrease or remain constant? It depends upon us humans, I guess.
