How do people put animals at risk?

By destroying their habitats and hunting them

Wildlife S.O.S: Are animals at risk?

Soils Southeast Asia, on balance, has a higher proportion of relatively fertile soils than most tropical regions, and soil erosion is less severe than elsewhere. Much of the region, however, is covered by tropical soils that generally are quite poor in nutrients. Often the profusion of plant life is more related to heat and moisture than to soil quality, even though these climatic conditions intensify both chemical weathering and the rate of bacterial action that usually improve soil fertility. Once the vegetation cover is removed, the supply of humus quickly disappears. In addition, the often heavy rainfall leaches the soils of their soluble nutrients, hastens erosion, and damages the soil texture. The leaching process in part results in laterites of reddish clay that contain hydroxides of iron and alumina. Laterite soils are common in parts of Myanmar, Thailand, and Vietnam and also occur in the islands of the Sunda Shelf, notably Borneo. The most fertile soils occur in regions of volcanic activity, where the ejecta is chemically alkaline or neutral. Such soils are found in parts of Sumatra and much of Java in Indonesia. The alluvial soils of the river valleys also are highly fertile and are intensively cultivated. Climate All of Southeast Asia falls within the warm, humid tropics, and its climate generally can be characterized as monsoonal (i.e., marked by wet and dry periods). Changing seasons are more associated with rainfall than with temperature variations. There is, however, a high degree of climatic complexity within the region. Temperatures Regional temperatures at or near sea level remain fairly constant throughout the year, although monthly averages tend to vary more with increasing latitude. Thus, with the exception of northern Vietnam, annual average temperatures are close to 80 °F (27 °C). Increasing elevation acts to decrease average temperatures, and such locations as the Cameron Highlands in peninsular Malaysia and Baguio in the Philippines have become popular tourist destinations in part because of their relatively cooler climates. Proximity to the sea also tends to moderate temperatures. Precipitation Much of Southeast Asia receives more than 60 inches (1,500 millimeters) of rainfall annually, and many areas commonly receive double and even triple that amount. The rainfall pattern is distinctly affected by two prevailing air currents: the northeast (or dry) monsoon and the southwest (or wet) monsoon. The northeast monsoon occurs roughly from November to March and brings relatively dry, cool air and little precipitation to the mainland. As the southwestward-flowing air passes over the warmer sea, it gradually warms and gathers moisture. Precipitation is especially heavy where the airstream is forced to rise over mountains or encounters a landmass. The east coast of peninsular Malaysia, the Philippines, and parts of eastern Indonesia receive the heaviest rains during this period. The southwest monsoon prevails from May to September, when the air current reverses and the dominant flow is to the northeast. The mainland receives the bulk of its rainfall during this period. Over much of the southern Malay Peninsula and insular Southeast Asia there is little or no prolonged dry season. This is especially marked in much of the equatorial region and along the east coast of the Philippines. While the dry and wet monsoons are important in explaining rainfall patterns, so too are such factors as relief, land and sea breezes, convectional overturning and cyclonic disturbances. These factors often are combined with monsoonal effects to produce highly variable rainfall patterns over relatively short distances. While many of the cyclonic disturbances produce only moderate rainfall, others mature into tropical storms—called cyclones in the Indian Ocean and typhoons in the Pacific—that bring heavy rains and destruction to the areas over which they pass. The Philippines are particularly affected by these storms. Plant life Tropical forests in Southeast Asia Tropical forests in Southeast Asia The seasonal nature and pattern of Southeast Asia’s rainfall, as well as the region’s physiography, have strongly affected the development of natural vegetation. The hot, humid climate and enormous variety of habitats have given rise to an abundance and diversity of vegetative forms unlike that in any other area of the world. Much of the natural vegetation has been modified by human action, although large areas of relatively untouched land still can be found. The vegetation can be grouped into two broad categories: the tropical-evergreen forests of the equatorial lowlands and the open type of tropical-deciduous, or “monsoon,” forests in areas of seasonal drought. The evergreen forests are characterized by multiple stories of vegetation, consisting of a variety of trees and plants. Although a large diversity of tree species is found in these forests, members of the Dipterocarpaceae family account for roughly half of the varieties. Deciduous forests are found in eastern Indonesia and those parts of the mainland where annual rainfall does not exceed 80 inches. Just as in the equatorial forest, a wide variety of species is normally the rule. Certain species, such as teak, have become highly valued commercially. Teak is found in parts of Indonesia, Myanmar, Thailand, and Laos. In addition to these two basic types of vegetation, other regional patterns reflect topography. Especially noteworthy are coastal and highland plant communities. Mangrove belts, of which there are more than 30 varieties, occur where silt is deposited in coastal areas. Upland forests dominated by maples, oaks, and magnolias are found especially on mainland mountain slopes. Human activity has been rapidly altering the stands of virgin forest in Southeast Asia. Most deforestation results from removal for fuelwood and clearing for agriculture and grazing. Although only a relatively small portion of the total land area has been permanently cleared for cultivation—e.g., in Java (Indonesia) and western Luzon (the Philippines)—in some areas shifting cultivation has brought about the replacement of virgin forest with secondary growth. In addition, nearly all countries have commercial logging industries; notable are those in Indonesia, Malaysia, Thailand, and Myanmar. A growing problem has been illegal logging. Thus, timber harvesting has come to contribute significantly to deforestation. Programs in social forestry and reforestation have yet to halt the rapid denuding of the landscape. Animal life Southeast Asia is situated where two major divisions of the world’s fauna meet. The region itself constitutes the eastern half of what is called the Oriental, or Indian, zoogeographic region (part of the much larger realm of Megagaea). Bordering along the south and east is the Australian zoogeographic region, and the eastern portion of insular Southeast Asia—Celebes (Sulawesi), the Moluccas, and the Lesser Sunda Islands—constitutes a transition zone between these two faunal regions. a classroom in Brazil More From Britannica education: Southeast Asia Southeast Asia is notable, therefore, for a considerable diversity of wildlife throughout the region. These differences are especially striking between the species of the eastern and western fringes as well as between those of the archipelagic south and the mainland north. The differences stem largely from the isolation, over varying lengths of geologic time, of species following their migration from the Asian continent. In addition, the tropical rain forests in many parts of the region, with their great diversity of vegetation, have made possible the development of complex communities of animals that fill specialized ecological niches. Especially numerous are arboreal and flying creatures. orangutans orangutansOrangutans (Pongo pygmaeus) in Sumatra, Indonesia. The distinction between the two faunal regions is best depicted by their mammal populations. In general, Australia is inhabited largely by marsupials (pouched mammals) and monotremes (egg-laying mammals), while Southeast Asia contains placental mammals and such hybrid species as the bandicoot of eastern Indonesia. Small mammals such as monkeys and shrews are the most numerous, while in many areas the larger mammals have been pushed into more remote areas and national preserves. Bears, gibbons, elephants, deer, civets, and pigs are found in both mainland and insular Southeast Asia, as are diminishing numbers of tigers. The Malayan tapir, a relative of the rhinoceros, is native to the Malay Peninsula and Sumatra, while the tarsier is found in the Philippines and parts of Indonesia. A number of rare endemic species are found in Indonesia and East (insular) Malaysia, including the Sumatran and Javan rhinoceros, the orangutan, the anoa (a dwarf buffalo), the babirusa (a wild swine), and the palm civet. As the pace of development accelerates and populations continue to expand in Southeast Asia, concern has increased regarding the impact of human activity on the region’s environment. A significant portion of Southeast Asia, however, has not changed greatly and remains an unaltered home to wildlife. The nations of the region, with only few exceptions, have become aware of the need to maintain forest cover not only to prevent soil erosion but to preserve the diversity of flora and fauna. Indonesia, for example, has created an extensive system of national parks and preserves for this purpose. Even so, such species as the Javan rhinoceros face extinction, with only a handful of the animals remaining in western Java

WHAT DOES THE WORLD GAIN WHEN WE PROTECT TIGERS? Tigers are one of the world’s most recognized animals. Throughout history they can be seen in cultural traditions across Asia, as well as in brand images and logos the world over. But while they might be omnipresent across our cultural landscape, their actual existence in the wild has been dramatically reduced to only a few pockets of their historical range. Wild tigers are now found in just 10 countries, their historical range shrunk by over 95%.er / WWF-US If tigers completely disappeared, we’d be losing so much more than an iconic species… Protecting water sources for millions of people Tiger habitats overlap nine of Asia’s most important watersheds which supply water to more than 800 million people. Protecting these tiger forests is the most cost-effective way to prevent droughts, reduce flooding, and limit the impacts of climate change. Protected Areas are proven to reduce deforestation and across Asia tigers are the driving force behind creating and effectively managing protected areas. For example, India recently declared its 51st Tiger Reserve, Srivilliputhur Megamalai, in southern India and this new protected area will safeguard more than 1,000km2 of key river habitat. Lose tigers, and lose entire forests Here in Cambodia, where I photographed the country’s last wild tiger in November 2007, tiger spirits were used by indigenous communities to help regulate the management of forests and wildlife. Harvesting of valuable plants was only permitted in certain times of the year and only after the tiger spirits had been appeased. Failure to adhere would result in wild tigers stalking you in the forest. However, with the extinction of the tiger the spirits have vanished, and the forests become an open free-for-all.aysia / Lau Ching Fong Protecting tigers also protects a multitude of other species Tiger-protected areas save much of Asia’s amazing wildlife. Take, for example, India’s Manas Tiger Reserve in Assam where tiger populations are increasing. In addition to tigers the grasslands and forests of Manas Tiger Reserve support the only viable global population of the world’s smallest, and rarest pig –pygmy hog – and, my personal favorite, the Bengal florican. This critically endangered gamebird, which I studied for my doctorate, finds a mate with an elaborate display involving males shooting themselves into the sky before plummeting down kicking their legs as if riding a bicycle. Without tigers, these and many more species would not be as well protected. A cultural and spiritual icon for millions There are plenty of examples of mythical animals, such as the unicorn, and extinct creatures, like the dodo and dinosaurs, which remain part of international consciousness. Tigers are a global phenomenon, but unless conservation is successful, they will only be known in zoos or in cultural media. A world without tigers would be economically and spiritually a much poorer place. Let us continue focusing our efforts towards doubling wild tigers and ensuring that this species does not become a vanished cultural icon.

Camera traps Technology is being used more and more in film and photography, For example, wildlife photographers sometimes use camera traps. When a photographer uses a camera frap the camera is hidden; for example, in a tree or on the ground so the animals cannot see it. When an animal moves near the camera, the camera is furned on and it takes a photo or a short film. Sometimes the camera is fixed onto an animal so it can take a film as the animal moves. The film then helps us to leam much more about the animal's life. Photo engineers of National Geographic design camera traps to help photographers hide cameras, for example in birds nests or on the ocean floor. They've designed camera traps for National Geographic photographers like Steve Winter, who takes photos of wild animals such as tigers, leopards, jaguars and bears. The camera trops are set up so that the animal looks straight into the camera. Steve thinks that if people see good photos of wild animals, they'll understand more about the animals and want to protect them. Photo engineers have to design cameras that will not break when they're being used in places like jungles or the ocean. Sometimes photographers use small remote-controlled cars to carry cameras. Technology is improving all of the time and helping photographers to take amazing photos. Thanks to the technology of camera traps, we can all see the world in new and interesting ways.
