The grasslands partly cover two BirdLife International Endemic Bird Areas, the Central Himalayas EBA in western Nepal and the western end of the Assam Plains EBA south of Bhutan. There are three near-endemic bird species including the vulnerable Manipur bush quail (Perdicula manipurensis). The 44 threatened and declining bird species of the grasslands include the Bengal florican (Houbaropsis bengalensis), lesser florican (Sypheotides indica), sarus crane (Grus antigone) and rufous-rumped grassbird (Graminicola bengalensis).
