Montane Forest Fragmentation and its Effects in Diurnal Frugivore Composition in North East Nigeria.

Abstract

Nigerian montane forests are: • satellite populations of many Afromontane endemics. • of a rare dry type, and harbour many threatened plant and animal species. • fall within the Cameroon Mountains Endemic Bird Area. • Forests range in altitude from ca. 1500 m to 2420 m on Gangirwal, Nigeria’s highest mountain. • vary in size from small fragments of less than one hectare, to riverine strips and impressive stands of over 20 km2 [1,2
