Diversity, abundance, and conservation status of woody species in a West African dry forest

This study presents data on woody plant species richness and diversity of an inaccessible dry forest Tula Mountains Woodland (TMW) located in the northeast Nigeria. TMW supports a minimally disturbed mosaic forest-woodland. We sampled 190 plots size 0.01-ha, spaced 50 m apart series line transects. found total 133 belonging to 88 genera 39 families 1.9 ha area total. Out species, 120 were identified level, 113 recorded as trees, shrubs lianas with diameter at breast height (dbh) ≥ 5 cm. Species accumulation curve was non-asymptotic. Fisher's logseries model suggests that communities are represented by high number rare species. Of 46 (38%) lacked evaluation conservation status IUCN. 74 (62%) evaluated 2 listed critically endangered, 3 vulnerable, 69 least concern. In TMW, 27% restricted Sudanian savannah biome, 61% occurred Zambezian biome. serves refugia for native northeastern
