Biological Invasions and Ecological Restoration in South Africa

Holmes, P.M.; Esler, K.J.; Gaertner, M.; Geerts, S.; Hall, S.A.; Nsikani, M.M.; Richardson, D.M.; Ruwanza, S. (2020)

This chapter provides an overview of the researchers and research initiatives relevant to invasion science in South Africa over the past 130 years, profiling some of the more recent personalities, particularly those who ...

Effects of exotic guava (Psidium guajava L.) invasion on soil properties in Limpopo, South Africa

Ruwanza, S.; Dondofema, F. (2020)

Many studies in South Africa have examined the impacts of alien plants on ecosystems, but none have assessed the impact of guava (Psidium guajava L.) invasion on soil properties. In this study, soils underneath guava‐invaded ...

Effects of Lantana camara invasion on vegetation diversity and composition in the Vhembe Biosphere Reserve, Limpopo Province of South Africa

Ruwanza, S. (2020)

Although the effects of invasive alien plants on natural ecosystems are widely acknowledged, the effects of specific plant species can be context dependent. The study examined changes in native vegetation diversity and ...

Eucalyptus-camaldulensis in South Africa - past, present, future

Hirsch, H.; Allsopp, M.H.; Canavan, S.; Cheek, M.; Geerts, S.; Geldenhuys, C.J.; Harding, G.; Hurley, B.P.; Jones, W.; Keet, J.H.; Klein, H.; Ruwanza, S.; van Wilgen, B.W.; Wingfield, M.J.; Richardson, D.M. (2020)

Eucalyptus camaldulensis can be seen as an iconic tree of superlatives. It is the eucalypt with the widest native range, and one of the most widely planted eucalypts around the globe. In South Africa, it is the most ...

Lantana camara invasion along road–river interchanges and roadsides in Soutpansberg, Vhembe Biosphere Reserve in South Africa

Ruwanza, S.; Mhlongo, E.S. (2020)

Roads and rivers act as conduits of alien plant invasion; however, little is known regarding the abundance and invasion extent of Lantana camara, an invasive shrub, along road–river interchanges and roadsides in South ...

Medium-term vegetation recovery after removal of invasive Eucalyptus camaldulensis stands along a South African river

Ruwanza, S.; Gaertner, M.; Esler, K.J.; Richardson, D.M. (Elsevier B.V., 2018)

Effective ecological restoration requires detailed monitoring to determine the success achieved through different interventions in achieving objectives. In 2017, we resurveyed riparian sites along the Berg River in the ...

Physical properties of soil in Pine elliottii and Eucalyptus cloeziana plantations in the Vhembe biosphere, Limpopo Province of South Africa

Ntshuxeko, V.E.; Ruwanza, S. (2020)

Plantation establishment using invasive alien plants is common in South Africa, but the effects of these plants on soil physical properties in the Vhembe biosphere is unknown. In this comparative study, soils underneath ...

Secondary invasion and weedy native species dominance after clearing invasive alien plants in South Africa: status quo and prognosis

Nsikani, M.M.; Geerts, S.; Ruwanza, S.; Richardson, D.M. (2020)

Clearing invasive alien plants often facilitates secondary invasion and/or weedy native species dominance instead of native biodiversity recovery. Secondary invasion and/or weedy native species dominance in turn can present ...
