Abstract

The carrying capacity (CC) of three grasslands differing in vegetation composition and biotic stress (fire and grazing) in Bundelkhand region (Uttar Pradesh, India) was assessed. Average carrying capacity, which express the ability of range unit to support adequately a constant number of grazing animals for a definite period without deteriorating its structure and function with respect to grazing value has been calculated on year-long basis. Dry sub-humid tropical grassland could carry 3.75 cow units ha⁻¹ yr⁻¹ as compared to 1.09 and 1.96 cow units ha¹ yr⁻¹ at the temperate and alpine sites respectively. The higher carrying capacity at all sites was found with controlled grazing. Excessive grazing affected the CC adversely. Fire treatment also enhanced the CC of the grassland. Controlled grazing, firing and a reduction in livestock population are recommended to sustain the carrying capacity of the grasslands in Bundelkhand region.
