Ecological Diversity and Floristic Composition of Woody Vegetation through Six Ecosystems in Zalingei Locality, Darfur State- Sudan.

This work aims to study some quantitative ecological characteristics of the woody plants in Zalingei Locality, Central Darfur State- Sudan. 6 sites: 3 in hill slopes and 3 in plains; were selected depending on differ topography and soil types. Quantitative data were collected according to the standard methods. The data was used to assess the floristic composition and dominance of species in each site, diversity and similarities between the sites using different methods. The results reveal the presence of 33 species inside sampled plots with relative differences between sites. Four species are dominating the studied area; Acacia senegal in site 1 and 4 in the low hill slopes, Albizia amara in site 3 in stony hill slope, Dichrostachys cinerea in sites 2 and 5 in plains and Acacia nilotica in site 6 in a sedentary plain. Species density is high in the area with varying amounts between sites. Four sites (1, 3, 5 and 6) recorded high diversity values. Site 4 recorded medium diversity values and site 2 recorded the lowest values. The percentage similarity between the sites is relatively high (68.29 – 77.77%). Signs of vegetation destruction were evident in sites 2 and 6. Conservation of the area is vital.
