Spiders of protected areas of northeastern India are poorly documented. Grasslands are among the most dynamic ecosystems for species survival over time. We report through the present study the assemblage of spiders for their diversity and abundance in two kinds of grasslands of Kaziranga National Park, Assam, India. Through active search, we recorded 63 species, out of which 29 species belonging to 16 genera and 09 families were recorded from the short grasslands, and 50 species belonging to 36 genera and 14 families were recorded from the tall grasslands. Species dominance varied in the two kinds of grasslands having different ecology. The most abundant species, Hippasa agelonides was recorded from the tall grasslands only. The most abundant species in the short grasslands was Tetragnatha mandibulata. The study reports the arthropod fauna from the grasslands of the national park for the first time.
