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 ...
ABSTRACT: Reporting on the state of plant invasions in South Africa
(Elsevier B.V., 2017)
A framework for engaging stakeholders on the management of alien species
(Elsevier Ltd., 2018)
Alien species can have major ecological and socioeconomic impacts in their novel ranges and so effective management actions are needed. However, management can be contentious and create conflicts, especially when stakeholders ...
Non-native species in urban environments: patterns, processes, impacts and challenges
Although urban ecosystems are hotspots for biological invasions, the field of invasion science has given scant attention to invasion dynamics and the challenges facing managers in towns and cities. This paper provides ...
Both complete clearing and thinning of invasive trees lead to short-term recovery of native riparian vegetation in the Western Cape, South Africa.
Questions: Most rivers in the Western Cape Province of South Africa are heavily invaded by alien trees, often resulting in profound changes in biodiversity and ecosystem functioning. Although large-scale management operations ...
Eucalyptus camaldulensis invasion in riparian zones reveals few significant effects on soil physico-chemical properties
(John Wiley & Sons, Ltd., 2015)
Many invasive alien plants alter soil-nutrient regimes of invaded ecosystems, affecting management outcomes. We assessed the effects of Eucalyptus camaldulensis invasions on physical and chemical properties of riparian ...
