Abstract
The study investigates the weed species composition and diversity in the Sunt Forest
Reserve, Khartoum State, Central Sudan. The floristic composition comprises 21 species
from 18 genera and 11 families. The Leguminosae family is the most abundant, with five
weed species, followed by Poaceae with four and Asteraceae with two. Tragus
berteronianus (Poaceae) is the most significant species based on the Importance Value
Index (IVI), with an IVI of 89.53%. Polygala erioptera (Polygalaceae) is the second most
significant, with an IVI of 85.71%, followed by Rorippa indica (Brassicaceae) and
Cyperus squarrosus (Cyperaceae) with IVIs of 80.44% and 72.32%, respectively. The
Shannon-Weiner Diversity Index for the area was 4.206, while the Simpson's Index of
Diversity (1 – D) was 0.05682. These values indicate a relatively high species diversity
compared to other subtropical forests worldwide.
