American Bison: A Symbol of Resilience and Conservation

The American bison, often called the buffalo, stands as an iconic symbol of the Great Plains, embodying the resilience of North America's wildlife. Once, these impressive creatures roamed the continent in vast herds, numbering an estimated 30-60 million before European settlement. The bison, North America's largest land mammal, can weigh up to 2,000 pounds, with males standing nearly six feet tall at the shoulder. Their immense size and presence evoke a sense of natural majesty, reflecting the expansive landscapes they inhabit.

Adapted to the extreme conditions of the plains, bison possess physical traits uniquely suited for survival. Their thick, shaggy fur provides insulation against freezing winters, while their dense muscle hump supports their heads, allowing them to plow through heavy snow in search of food. Unlike other grazers that may struggle in winter, bison use their large, powerful heads to sweep aside snow, uncovering the grasses beneath. Their diet consists mainly of grasses and sedges, which are abundant in prairie ecosystems. This grazing behavior is crucial to maintaining the health of grasslands, as it encourages new plant growth and prevents overgrowth that could stifle other species.

Historically, bison held profound significance for Indigenous peoples, who relied on them for sustenance, clothing, shelter, and tools. Every part of the animal was used, highlighting a deep respect and sustainable relationship with the environment. However, the 19th century marked a tragic period for bison, as overhunting and habitat destruction nearly led to their extinction. The U.S. government sanctioned widespread bison killings, partially to weaken Indigenous communities reliant on them, drastically reducing their numbers to only a few hundred by the 1880s.

In the 20th century, dedicated conservation efforts by individuals, Indigenous communities, and organizations like the National Park Service helped revive bison populations. Today, they are protected in national parks and wildlife refuges, symbolizing a triumph of conservation. The American bison's story is one of survival and revival, embodying the enduring spirit of the natural world. Their continued presence enriches North American ecosystems, offering a living testament to the importance of protecting wildlife and preserving cultural heritage.

Wild water buffalo: tamaraw

Tamaraw (Bubalus mindorensis) is a wild water buffalo endemic to the island of Mindoro, Philippines. It is one of the world’s critically endangered species.

Tamaraw is a small buffalo; females have been estimated to weigh approximately 300 kg. It closely resembles the Philippine water buffalo (carabao) except for its massive horns, which grow upward and caudally forming a V.

82% of adult males were lone individuals, while 66% of adult females were either solitary or accompanied by calves. Tamaraw feed primarily on grasses and young bamboo shoots in open grasslands.

The main current threat to the Tamaraw is habitat loss due to farming by resettled and local people. Historically, this species was hunted for both subsistence and sport, which led to a period of drastic decline in numbers of individuals and populations. The introduction of cattle in the past also caused a rinderpest epidemic that contributed to a further decline in numbers.

American bison

Bison are hoofed mammals that have curved horns and a dark brown, shaggy coat. They are distinguished by a shoulder hump. The scientific name for American bison is Bison bison.

The bison’s hump helps support its huge head. The hair on the hump and on the bison’s whole front end is two to five times thicker than the hair on the rear end. The bison also has sharp, curved horn.

Bison bison

Larger than cattle, bison have 14 pairs of ribs compared to the 13 that cattle have. Long before the first Europeans arrived in North America, American bison roamed the continent from Great Slave Lake in what is now Canada to what is now Mexico.

Bison measure about 11 and one-half feet in length. It stands about 6.5 feet (2 meters) tall at the shoulder. It may weigh about 900 kgs. The females are smaller.

American bison prefer grasslands and open prairies. Today the American bison is found mainly in protected areas such as national parks.

They are herbivores. Herbivores are animals that eat plants. Bison eat mostly prairie grasses and plants.

Bos gaurus

Bos gaurus
Bos gaurus one of several species of wild cattle, belonging to the group of wild oxen. In total there are 9 species and 21 subspecies of wild oxen in the world, belonging to four genera.

These is include the Asiatic buffalo, African buffalo, true cattle and bison. The ancestors of wild oxen are known to have evolved in Asia some 20 million years ago.

The gaur, commonly referred as the Indian bison, belongs to the subfamily Bovidae of the order Artiodactyla and is the largest living bovine, confined to the Oriental biogeographic region.

Bos gaurus gaurus (India and Nepal), Bos gaurus readei (Myanmar and Indochina) and Bos gaurus hubbacki (Thailand south of the isthmus of Kra and West Malaysia) are the three commonly recognized subspecies of gaur.

Bos gaurus bull weigh 600-1000 kg and stand 1.6 to 1.9 m at the shoulder, whereas the cows are about 10 cm shorter and weigh about one fourth less than the males.

One of the most striking features of the gaur is the muscular ridge upon its shoulder, which slope down to the middle of the back, ending in an abrupt dip.

This is often referred to as the dorsal ridge and is the result of the extension of the dorsal vertebrae. Both sexes have horns. In the males the horns are especially larger at the base, with more outward swath and curvature at the tips is less.

There is a high, bulging forehead ridge between the horns.

Once common throughout South and Southeast Asia, gaurs now survive only in scattered remnant herds of up to 30 animals in the hill forests of India, Burma, Thailand, Laos, Kampuchea, Vietnam and the Malay Peninsula.

Historically, the largest concentration have coexisted with farmers in areas of shifting cultivation. The animals adjust to disturbed land, and they also adapt to man’s presence if not unduly harassed.

For example gaurs will feed in agriculture fields, along roadsides and near occupied houses. Herds in national parks feed peacefully while tourists stand by. Gaurs in zoos also become quite tame and manageable.
