Small urban centres as launching sites for plant invasions in natural areas: insights from South Africa
Alien species are often first introduced to urban areas, so it is unsurprising that towns and cities are often hotspots for invasions. However, while large cities are usually the first sites of introduction, small towns ...
Alien plants as mediators of ecosystem services and disservices in urban systems: a global view
Urban areas have unique assemblages of species which are governed by novel ecological processes. People living in these environments have specific needs and demands in terms of ecosystem services (ES). Urban ecosystems are ...
The effectiveness of active and passive restoration on recovery of indigenous vegetation in riparian zones in the Western Cape, South Africa: A preliminary assessment
Riparian ecosystems in South Africa's fynbos biome are heavily invaded by alien woody plants. Although largescale clearing of these species is underway, the assumption that native vegetation will self-repair after ...
Invasive plants as drivers of regime shifts: identifying high-priority invaders that alter feedback relationships
(John Wiley & Sons Ltd, 2014)
Aim A major challenge for invasion ecology is to identify high-impact invaders to guide prioritization of management interventions. We argue that species with the potential to cause regime shifts (altered states of ecosystem ...
Biological invasions in the Cape Floristic Region: history, current patterns, impacts, and management challenges
(Oxford University Press, 2015)
The Cape Floristic Region (CFR) is the most invaded terrestrial area in South Africa in terms of: the conspicuous prominence of (mainly woody) invasive plants (Fig 12.1, Plate 12) (Henderson 2007); the area invaded as ...

Impacts of invasive Australian acacias: implications for management and restoration
(Blackwell Publishing Ltd, 2011)
Aim The biophysical impacts of invasive Australian acacias and their effects on ecosystem services are explored and used to develop a framework for improved restoration practices. Location South Africa, Portugal and ...
Effects of alien plants on ecosystem structure and functioning and implications for restoration: Insights from three degraded sites in South African fynbos
(Springer Science+Business Media B.V., 2011)
We investigated the type and extent of degradation at three sites on the Agulhas Plain, South Africa: an old field dominated by the alien grass Pennisetum clandestinum Pers. (kikuyu), an abandoned Eucalyptus plantation, ...
Successional changes on a former tank range in eastern Germany: Does increase of the native grass species Molinia caerulea cause decline of less competitive Drosera species?
(Elsevier GmbH., 2010)
Invasion of natural ecosystems by weedy grasses is often associated with increasing levels of disturbance. However, there is substantial evidence that cessation of disturbance can also lead to plant invasions. This paper ...
