The tiger is a rare animal that is essential to the variety and health of an ecosystem. At the top of the food chain, it is a top predator. As a result, the existence of tigers in the forest is a sign that the ecology is healthy. Tiger conservation in forests safeguards a variety of other species habitats. a b c d e f g Goodrich, J.; Wibisono, H.; Miquelle, D.; Lynam, A.J; Sanderson, E.; Chapman, S.; Gray, T.N.E.; Chanchani, P. & Harihar, A.

But this ratio might change if the tigress is with cubs who have started feeding on the meat. A tigress raring her cubs might have to hunt 2 times in 10 days.

Panthera tigris trinilensis lived about 1.2million years ago and is known from fossils excavated near Trinil in Java. [36] The Wanhsien, Ngandong, Trinil, and Japanese tigers became extinct in prehistoric times. [37] Tigers reached India and northern Asia in the late Pleistocene, reaching eastern Beringia, Japan, and Sakhalin. Some fossil skulls are morphologically distinct from lion skulls, which could indicate tiger presence in Alaska during the last glacial period, about 100,000 years ago. [38] In 2016, an estimate of a global wild tiger population of approximately 3,890 individuals was presented during the Third Asia Ministerial Conference on Tiger Conservation. [133] [134] The WWF subsequently declared that the world's count of wild tigers had risen for the first time in a century. [135] Tiger on a Tree" follows the life of a tiger. It starts off with showing a tiger who is on shore, and seems like he is in little bit of a rush. As he is running off somewhere, he needs to pass some obstacles. The first one is the ocean. The desperate tiger has to be bold enough to go across. Then as he keeps on running, he passes a deer. The deer, who becomes frightened, also flees. While the tiger runs, he finds a tree. Without any hesitation, he climbs it! At this point of the story, nobody knows why the tiger has to keep on running, until a man with a net shows up. He yells out that the tiger is on the tree, and then a group of other people show up. They all grab onto the net and traps the tiger. The poor and desperate tiger does not know what to do. Will he get caught? If so, what will become of him? You can feel the tiger's emotions. McDougal, Charles (1977). The Face of the Tiger. London: Rivington Books and André Deutsch. pp.63–76.

The Tiger Species Survival Plan has condemned the breeding of white tigers, alleging they are of mixed ancestry and of unknown lineage. The genes responsible for white colouration are represented by 0.001% of the population. The disproportionate growth in numbers of white tigers points to inbreeding among homozygous recessive individuals. This would lead to inbreeding depression and loss of genetic variability. [71]
