Diversity and control of invasive plant species: a case study of Uganda Wildlife Conservation Education Centre (UWEC)

Abstract

Alien plant species distribution and population may be affected by topography, soils and climate change. In this study we aimed to examine the distribution of invasive alien species diversity, richness and evenness in terrestrial habitats in UWEC, through documenting an inventory. We carried out survey in 3 strata which had 12 plots each. We established 12 experimental plots in each stratum giving a total of 36 plots. In each plot we recorded species name and abundance. We measured species distribution and found that soil type and grazing animals affected the invasive alien plant species diversity. These results suggest that soil type and grazing power may affect invasive alien plant species diversity in captive centres, which should be considered in the future management of plant invasions. More studies should be undertaken to establish the factors underlying the pattern of invasive alien species at UWEC. This will give a hint on the how best these alien species can be controlled. The study further recommends that an investigative study be undertaken to assess the effectiveness of the control methods that have employed at UWEC and suggested alternative approaches.
