A 1997 documentary.
There are only about 300 remaining Siberian Tigers in the wild, restricted to a section of far Eastern Russia, near the coast. Wildlife biologists risk life and limb to track the tiger and research its movements and habits. They sedate the animals so the tigers can be measured and collared. One Russian scientist is shown raising two tigers which he found orphaned as cubs. He keeps the tigers in a cage, then allows the beasts into a fenced forest-like enclosure. The efforts of these scientists are in contrast to those of poachers, who kill the tigers for their pelts, as well as for body parts to be marketed in traditional Chinese medicine.
From the Nat-Geo site
Siberian (or Amur) tigers are the world's largest cats.
They live primarily in eastern Russia's birch forests, though some exist in China and North Korea. Though their northern climate is far harsher than those of other tigers, these animals have some advantages. Northern forests offer the lowest human density of any tiger habitat, and the most complete ecosystem. The vast woodlands also allow tigers far more room to roam, as Russia's timber industry is currently less extensive than that of many other countries.
Threats to Survival
Tigers are the largest of all wild cats and are renowned for their power and strength. There were once nine tiger subspecies, but three became extinct during the 20th century. Over the last hundred years, hunting and forest destruction have reduced overall tiger populations dramatically. Tigers are hunted as trophies and also for body parts that are used in traditional Chinese medicine. All six remaining tiger subspecies are threatened, and many protection programs are in place. Poaching is a reduced—but still very significant—threat to Siberian tigers.
Tigers live alone and aggressively scent-mark large territories to keep their rivals away. They are powerful hunters that travel many miles to find prey, such as elk and wild boar, on nocturnal hunts. Tigers use their distinctive coats as camouflage (no two have exactly the same stripes) and hunt by stealth. They lie in wait and creep close enough to attack their victims with a quick spring and a fatal pounce. A hungry tiger can eat as much as 60 pounds in one night, though they usually eat less.
Despite their fearsome reputation, most tigers avoid humans; however, a few do become dangerous maneaters. These animals are often sick and unable to hunt normally, or live in areas where their traditional prey has vanished.
Females give birth to litters of two to six cubs, which they raise with little or no help from the male. Cubs cannot hunt until they are 18 months old, and remain with their mothers for two to three years, when they disperse to find their own territory.
