According to the International Union for Conservation of Nature and Natural Resources (IUCN) Red List of Threatened Species, tigers generally do not require a specific type of shelter. They are mainly found in the forests of tropical Asia, but they have historically been found in colder climate areas.
Tigers are solitary animals and each has a territory or home range that it occupies. The size of this home range depends primarily on the amount of prey that can be found and can vary from 20 square kilometers to over 400 square kilometers. For example, in areas where prey is abundant, an individual tiger's home range is smaller when compared to an area where prey is more scarce. There is no shared overlap between adult male home ranges, but several adult female home ranges may overlap with that of a single male.
