The Mudumalai National Park hosts a variety of flora such as the Begonia malabarica, rosewood, coral trees, etc.

The Nilgiri Biosphere Reserve is the first Indian biosphere reserve. Plants and animals confined to a particular area are referred to as the flora and fauna.

Endemic species are the animals and plants found in a specific area.

Endangered species or threatened wild animals in the Waynad Wildlife Sanctuary are the black buck, marsh crocodile, python, etc. Killing or poaching of animals is prohibited in the Waynad Wildlife Sanctuary. The only way to protect these animals from extinction is by increasing awareness. Project Tiger is a government initiative, launched to ensure the survival of the tiger population.

Red Data Book provides the important information about endangered species.

Migration is the seasonal movement of birds at regular intervals of the year to overcome adverse effects of the changing climate. Birds migrate in search of warmer places for egg laying, better shelters and to escape unfavourable conditions. e.g. A number of birds migrate to the Vedanthangal Bird Sanctuary. In other words, when natural habitats are not conducive for breeding, birds move to safer areas to breed, which is called migration. Birds that fly from far-off places to reach a new habitat are known as migratory birds.
