“…The outcomes of the current study revealed the detrimental impacts of P. velutina on woody species composition and diversity at the Tshidilamolomo and Mabule sites. Several studies have found that the invasion of Prosopis species has reduced native plant richness and density [ 32 , 40 , 41 , 42 , 43 ]. This suggests that the vigorous and rapid growth of this invasive species, which has reached a large proportional representation, is accountable for the strong impact on native woody plant species along the Molopo River.…”

Invasive alien species represent one of the main threats to biodiversity and species extinction. This is the case for the genus Prosopis, among which Prosopis velutina is the most invasive and common tree species along the Molopo River in the North-West Province, impacting native plant communities. However, its impact on the composition and diversity of native woody species remains poorly investigated in the area. Thus, this study aimed to assess the impact of P. velutina on native woody plant composition and diversity across three sites along the Molopo River. At each site, five quadrats of 20 × 20 m2 were randomly established in invaded and adjacent uninvaded stands. A comparative methodological approach was adopted, and the woody plants in invaded and uninvaded stands with similar site conditions were sampled. The results showed that native woody species density differed significantly (p < 0.05) between invaded and uninvaded stands, except for Bray sites, where there was a marginal difference (p = 0.6). The overall native woody species density decreased by 79.7% in the invaded stand. However, non-metric multidimensional scaling (nMDS) and analysis of similarity (ANOSIM) indicated significant differences in native tree composition between invaded and uninvaded stands at all sites. In all three sites, all ecological indices had significantly lower values in invaded stands compared to uninvaded stands. The decrease in all ecological indices in invaded over uninvaded stands indicated that P. velutina invasion reduced the diversity of native woody plant species. Due to the incessant spread of P. velutina, it may become a long-term dominant species with an increasing impact on the native vegetation. Therefore, the findings of this study call for urgent management and appropriate control measures against the ongoing spread of this invader within the riparian zones of the Molopo River in North-West Province.

“…total N concentrations in soils under P. juliflora were higher than those under open grassland areas. In Afar region of Ethiopia, a study by Shiferaw et al [14] shows that invasion of P. juliflora changed the physicochemical properties in Teru and Yalow Woredas. Several findings show that positive effects of P. juliflora on soil properties overweight the negative ones.…”

This paper aimed to review the effects of P. juliflora (hereafter P. juliflora is represented by P. juliflora) on environmental factors in Ethiopia, management options and take up lessons learned elsewhere, and discuss about utilization and management of P. juliflora. It addresses relevant scientific information based on the evaluation of data collected from different journals, books, manuals, and various reports using the systematic review method. Invasion of P. juliflora had positive effects on soil properties, negative effects on plant diversity, human health, livestock health, and other economic losses. Its negative effects are outweighing its positive effects. The main negative effects of P. juliflora are its biotic factors such as allopathic chemicals and active ingredients such as phenolic compounds that are impairing animals and human beings. Mechanical, chemical, management by utilization, fire, disruption of its phenological stages, and biological control methods are among control methods of the species. However, these control methods have their pros and cons for its management. The review was based on limited research findings and sources because there are limitations in research works regarding P. juliflora and its management. This review is used to know the invasion of P. juliflora and its management options in Ethiopia and other similar tropical countries across the world.
