Tiger size does not vary with that. Because a single tiger in kaziranga nearly has same habitat and quantity of prey compared to single tiger of other national parks, because it has highest density of tigers in the world. And that is enough to say that they are of same size IMO. Elephant grass IMO does not make herbivores and in turn carnivores huge. Any kind of thick vegetation is enough for herbivores to grow big. And all assam reserves have it in plenty. (04-27-2016, 08:39 PM)parvez Wrote:(04-27-2016, 08:13 PM)Pckts Wrote: Doesn't kaziranga have more elephant grass and water compared to other places in Assam? Elephant grass and water would both possibly contribute to size increase, trekking through rough terrain and wading through water could both contribute to a larger cat. On top of the fact that Kaziranga is the only place on earth to still house Rhino, Elephant, Gaur and Water buffalo, could all contribute to larger sizes compared to others. The rich grass and water is shown to support the largest mammals in India and all in one place, I see no reason why they wouldn't house the largest tigers in assam as well. So you have the highest density of Tigers (only the strongest and largest will survive) with the most vegetation and water (hard trekking and much food for the largest herbivores in India) will all contribute to what I think will be one of the largest Tiger populations in the world. You see the same scenario in Ngorongoro Crater (year round buffalo herds and nutrient rich year round vegetation) as well as the Okovango Delta (watery terrain and tough Trekking) with Lions. Both populations are argued as the largest Lion species in the world as well. (04-27-2016, 09:24 PM)Pckts Wrote:But the camera trap pictures show otherwise.

Some big boys there...
What the heck is around that tigers neck on post #1? If it is a collar, can we find the Dr. who did it and ask some questions on size?
@parvez
Camera traps are very useful when determining ID's and Tiger Density but not useful when determining size. To many factors come into play, no body can tell if a tiger is larger or smaller than another unless the same location's camera traps are used. That would only be useful for determining size for that exact location and nothing more. I do agree on having the help of others who have experience in the areas we are discussing give their 2 cents though, its definitely something you and I are curious about, obviously. I enjoy the discussion, I'm definitely not saying you're wrong and I'm right or vice versa, we're just expressing our opinions on the matter.
Little more on Kaziranga Landscape
ABOUT KAZIRANGA HOME / ABOUT KAZIRANGA  *This image is copyright of its original author Kaziranga is located between latitudes 26°30' N and 26°45' N, and longitudes 93°08' E to 93°36' E within two districts in the Indian state of Assam -the Kaliabor subdivision of Nagaon district and the Bokakhat subdivision of Golaghat district. The park is approximately 40 km (25 mi) in length from east to west, and 13 km (8 mi) in breadth from north to south. Kaziranga covers an area of 378 km2 (146 sq mi), with approximately 51.14 km2 (20 sq mi) lost to erosion in recent years. A total addition of 429 km2 (166 sq mi) along the present boundary of the park has been made and designated with separate national park status to provide extended habitat for increasing the population of wildlife or, as a corridor for safe movement of animals to Karbi Anglong Hills. Elevation ranges from 40 m (131 ft) to 80 m (262 ft). The park area is circumscribed by the Brahmaputra River, which forms the northern and eastern boundaries, and the Mora Diphlu, which forms the southern boundary. Other notable rivers within the park are the Diphlu and Mora Dhansiri. Kaziranga has flat expanses of fertile, alluvial soil formed by erosion and silt deposition by the Brahmaputra. The landscape consists of exposed sandbars, riverine flood-formed lakes known as, beels, (which make up 5% of the surface area), and elevated regions known as, chapories, which provide retreats and shelter for animals during floods. Many artificial chapories have been built with the help of the Indian Army to ensure the safety of the animals.[Kaziranga is one of the largest tracts of protected land in the sub-Himalayan belt, and due to the presence of highly diverse and visible species, has been described as a "biodiversity hotspot"[The park is located in the Indomalaya ecozone, and the dominant biomes of the region are Brahmaputra Valley semi-evergreen forests of the tropical and subtropical moist broadleaf forests biome and a frequently flooded variant of the Terai-Duar savanna and grasslands of the tropical and subtropical grassland, savannas and shrublands biome. Climate of Kaziranga The park experiences three seasons: summer, monsoon, and winter. The winter season, between November and February, is mild and dry, with a mean high of 25 °C (77 °F) and low of 5 °C (41 °F). During this season, beels and nallahs (water channels) dry up. The summer season between March and May is hot, with temperatures reaching a high of 37 °C (99 °F). During this season, animals usually are found near water bodies. The rainy monsoon season lasts from June to September, and is responsible for most of Kaziranga's annual rainfall of 2,220 mm (87 in). During the peak months of July and August, three-fourths of the western region of the park is submerged, due to the rising water level of the Brahmaputra. The flooding causes most animals to migrate to elevated and forested regions outside the southern border of the park, such as the Karbi Hills. However, occasional dry spells create problems as well, such as food shortages for the wildlife in the park.

FLORA & FAUNA HOME / ABOUT KAZIRANGA / FLORA & FAUNA Kaziranga contains significant breeding populations of 35 mammalian species, of which 15 are threatened as per the IUCN Red List (International Union for Conservation of Nature). The park has the distinction of being home to the world's largest population of the Great Indian One-Horned Rhinoceros (1,855),Wild Asiatic Water Buffalo (1,666) and Eastern Swamp Deer (468). Significant populations of large herbivores include elephants (1,940), gaur (30) and sambar (58). Small herbivores include the Indian Muntjac, wild boar, and hog deer.
 *This image is copyright of its original author Kaziranga is one of the few wild breeding areas outside Africa for multiple species of large cats, such as Indian Tigers and Leopards. Kaziranga was declared a Tiger Reserve in 2006 and has the highest density of tigers in the world (one per five km²), with a population of 86, as per the 2000 census. Other felids include the Jungle Cat, Fishing Cat, and Leopard Cats. Small mammals include the rare Hispid Hare, Indian Gray Mongoose, Small Indian Mongooses, Large Indian Civet, Small Indian Civets, Bengal Fox, Golden Jackal, Sloth Bear, Chinese Pangolin, Indian Pangolins, Hog Badger, Chinese Ferret Badgers, and Particolored flying squirrels. Nine of the 14 primate species found in India occur in the park. Prominent among them are the Assamese Macaque, Capped, Golden Langur, as well as the only ape found in India, the Hoolock Gibbon. Kaziranga's rivers are also home to the endangered Ganges Dolphin.
Kaziranga has been identified by Birdlife International as an Important Bird Area It is home to a variety of migratory birds, water birds, predators, scavengers, and game birds. Birds such as the Lesser White-fronted Goose, Ferruginous Duck, Baer's Pochard duck and Lesser Adjutant, Greater Adjutant, Black-necked Stork, and Asian Openbill stork migrate from Central Asia to the park during winter. Riverine birds include the Blyth's Kingfisher, White-bellied Heron, Dalmatian Pelican, Spot-billed Pelican, Spotted Greenshank, and Black-bellied Tern. Birds of prey include the rare Eastern Imperial, Greater Spotted, White-tailed, Pallas's Fish Eagle, Grey-headed Fish Eagle, and the Lesser Kestrel.
Kaziranga was once home to seven species of vultures, but the vulture population reached near extinction, supposedly by feeding on animal carcasses containing the drug Diclofenac. Only the Indian Vulture, Slender-billed Vulture, and Indian White-rumped Vulture have survived.Game birds include the Swamp Francolin, Bengal Florican, and Pale-capped Pigeon.
Other families of birds inhabiting Kaziranga include the Great Indian Hornbill and Wreathed Hornbill, Old World babblers such as Jerdon’s and Marsh Babblers, weaver birds such as the common Baya Weaver, threatened Finn's Weavers, thrushes such as Hodgson's Bushchat and Old World warblers such as the Bristled Grassbird. Other threatened species include the Black-breasted Parrotbill and the Rufous-vented Prinia.Two of the largest snakes in the world, the Reticulated Python and Rock Python, as well as the longest venomous snake in the world, the King Cobra, inhabit the park. Other snakes found here include the Indian Cobra, Monocled Cobra, Russell's Viper, and the Common Krait. Monitor lizard species found in the park include the Bengal monitor and the Water Monitor. Other reptiles include fifteen species of turtle, such as the endemic Assam Roofed Turtle and one species of tortoise, the Brown Tortoise.42 species of fish are found in the area, including the Tetraodon. Vegetation of Kaziranga National Park Four main types of vegetation exist in the park. These are alluvial inundated grasslands, alluvial savanna woodlands, tropical moist mixed deciduous forests, and tropical semi-evergreen forests. Based on Landsat data for 1986, percent coverage by vegetation is: tall grasses 41%, short grasses 11%, open jungle 29%, swamps 4%, rivers and water bodies 8%, and sand 6%.
There is a difference in altitude between the eastern and western areas of the park, with the western side being at a lower altitude. The western reaches of the park are dominated by grasslands. Tall elephant grass is found on higher ground, while short grasses cover the lower grounds surrounding the beels or flood-created ponds.Annual flooding, grazing by herbivores, and controlled burning maintain and fertilize the grasslands and reeds. Common tall grasses are sugarcanes, spear grass, elephant grass, and the common reed. Numerous forbs are present along with the grasses. Amidst the grasses, providing cover and shade are scattered trees—dominant species including kumbhi, Indian gooseberry, the cotton tree (in savanna woodlands), and elephant apple (in inundated grasslands)]
Thick evergreen forests, near the Kanchanjhuri, Panbari, and Tamulipathar blocks, contain trees such as Aphanamixis polystachya, Talauma hodgsonii, Dillenia indica, Garcinia tinctoria, Ficus rumphii, Cinnamomum bejolghota, and species of Syzygium. Tropical semi-evergreen forests are present near Baguri, Bimali, and Haldibari. Common trees and shrubs are Albizia procera, Duabana grandiflora, Lagerstroemia speciosa, Crateva unilocularis, Sterculia urens, Grewia serrulata, Mallotus philippensis, Bridelia retusa, Aphania rubra, Leea indica, and Leea umbraculifera. There are many different aquatic floras in the lakes and ponds, and along the river shores. The invasive water hyacinth is very common, often choking the water bodies, but it is cleared during destructive floods. Another invasive species, Mimosa invisia, which is toxic to herbivores, was cleared by Kaziranga staff with help from the Wildlife Trust of India in 2005.
Water pollution due to run-off from pesticides from tea gardens, pose a hazard to the ecology of the region.Invasive species such as Mimosa and wild rose have posed a threat to the native plants in the region. To control the growth and irradiation of invasive species, research on biological methods for controlling weeds, manual uprooting and weeding before seed settling are carried out at regular intervals.Grassland management techniques, such as controlled burning, are effected annually to avoid forest fires
The Wildlife wing of the forest department of the Government of Assam, headquartered at Bokakhat, is responsible for the administration and management of Kaziranga.The administrative head of the park is the director, who is a conservator-level officer. A divisional forest officer is the administrative chief executive of the park. He is assisted by two officers with the rank of assistant conservator of forests. The park area is divided into four ranges, overseen by range forest officers. The four ranges are the Burapahar, Baguri, Central, and Eastern. They are headquartered at Ghorakati, Baguri, Kohora, and Agoratoli, respectively. Each range is further sub-divided into beats, headed by a forester, and sub-beats, headed by a forest guard.
