Africa is home to globally important biodiversity.Straddling the equator and extending temperate latitudes (at 37°N 34°S; not including oceanic islands such as Marion Prince Edward), continent accommodates a variety of ecosystems biomes, tropical forests, savanna montane grasslands, deserts, Mediterranean-type (Olson et al., 2011;Linder, 2014).The has remained relatively stable in Cenozoic period (66 2.5 million years ago, Ma), despite dramatic geological events, shifting coastlines, volcanism formation rift valley (Couvreur 2021).Africa rich diversity vascular plants, with over 65 000 species recorded on its surrounding (Qian 2021).This equates approximately 18.5% plant (Antonelli 2023).However, efforts catalogue African composition are uneven, certain regions (e.g.tropical east central Africa) being well catalogued others (e.g.Sudan) barely explored (Marshal 2016).At same time, increased ecological evolutionary research points varied patterns diversification assembly flora; however, there lack wider consolidation disparate knowledge.This Special Issue aims bring together pan-African build holistic synthesis knowledge ecology evolution plants.

Nigeria is one of the most floristic rich countries on continent Africa due to variation in climate, which favors growth several species. Sadly, its biodiversity threatened world mainly deforestation and various forms unsustainable land use patterns, are human activities. However, these anthropogenic activities more prevalent Nigeria's northern savanna zone (NSZ). In this study, we present first regional Conservation assessments Red Listing tree species Northern Savanna Zone (NSZ) according International Union for Nature (IUCN) criteria categories. We recorded 31 as utilized region region. For assessments, provided fundamental taxonomic information each species, their local names, uses. This study extent occurrence, area occupancy, population size trend, a description habitats, ecological requirements; discussion threats affecting habitats. further also inform conservation actions research needed ensure future sustainable Overall, about 97% taxa were evaluated (41% Endangered, 31% critically endangered, 24% Vulnerable, 4% Least Concerned). Based this, recommend adoption risk status develop sound strategies measures management flora inundated
