Pygmy hog of Assam is a grassland indicator

Grassland indicator species are species of plants, animals, or other organisms whose presence, absence, or abundance reflect the condition of grassland ecosystems. They are used to assess the health and quality of these habitats, as well as the effects of environmental changes such as grazing pressure, fire regimes, and human activities.

These species help scientists and land managers evaluate grassland ecosystems and implement conservation strategies tailored to maintain or restore their ecological health.
