Identifying and categorizing stakeholders for protected area expansion around a national park in Namibia
(2019)Protected areas and adjacent landscapes are increasingly being viewed as integrated. A more general awareness is emerging of the relevance of collectively managed landscapes for conservation and human well-being. In Namibia, ... -
Identifying challenges to building an evidence base for restoration practice
(MPDI AG, Basel, Switzerland, 2015)Global acknowledgement of ecological restoration, as an important tool to complement conservation efforts, requires an effort to increase the effectiveness of restoration interventions. Evidence-based practice is purported ... -
Identifying research questions for the conservation of the Cape Floristic Region
(2019)We conducted a survey among people working in the nature conservation community in an implementation, research or policy capacity to identify research questions that they felt were important for ensuring the conservation ... -
Impact of alien pines on local arbuscular mycorrhizal fungal communities – evidence from two continents
(Federation of European Microbiological Societies, 2016)The introduction of alien plants can influence biodiversity and ecosystems. However, its consequences for soil microbial communities remain poorly understood. We addressed the impact of alien ectomycorrhizal (EcM) pines ... -
The impact of anthropogenically induced degradation on the vegetation and biochemistry of South African palmiet wetlands
(Springer, 2018)There are many different anthropogenic causes of wetland degradation, such as disturbances which affect the physical structure of wetlands, resulting in erosion (altered fire regimes, road and railway building through ... -
The impact of data precision on the effectiveness of alien plant control programmes: a case study from a protected area
(Springer, 2018)Successful long-term invasive alien plant control programmes rely on alien plant distribution and abundance data to assess, prioritise, implement and monitor the efficacy of the programme. Here we assess the impact of data ... -
The impact of pine plantations on fynbos above-ground vegetation and soil seed bank composition
(Elsevier B.V., 2017)Pine plantations and pine invasions have numerous impacts on native ecosystems in the Fynbos biome of South Africa. The severity of these impacts greatly determines the extent of potential ecosystem recovery after the pines ... -
Impact of Prosopis (mesquite) invasion and clearing on vegetation species composition and diversity in semi-arid Nama-Karoo rangeland, South Africa
(Taylor & Francis, 2016)The Nama-Karoo biome occupies 28% of South Africa’s land area. Alien leguminous trees of the genus Prosopis have invaded large tracts of Nama-Karoo rangeland. We evaluated the impact of Prosopis invasion and clearing on ... -
Influence of fire on critically endangered Swartland Shale Renosterveld in the Cape Floristic Region
(International Association for Vegetation Science, 2018)Questions: The degree to which renosterveld shrublands are fire-dependent is currently unclear. To address this issue, the following questions were asked: (1) does smoke stimulate germination of soil-stored seeds in ... -
Ingress of Lantana in dry tropical forest fragments: Edge and shade effects
(2008-01-25)Invasion of native communities by exotic species is considered the second largest threat to global biodiversity. Since the tropics are highly populated, they experience greater pressure of invasive species, as the ... -
Insights into invasion and restoration ecology: Time to collaborate towards a holistic approach to tackle biological invasions
(Creative Commons, 2012)The aim of our study is to provide an integrated framework for the management of alien plant invasions, combining insights and experiences from the fields of invasion and restoration ecology to enable more effective ... -
Integrating multiple perspectives on the human-nature relationship: A reply to Fletcher 2017
(Taylor & Francis Group, LLC, 2019)The concept of “connectedness with nature” is increasingly used in environmental and sustainability discourse. However, this construct has also been critiqued and proponents charged with harboring an ambivalence that ... -
Interdisciplinary and multi-institutional higher learning: reflecting on a South African case study investigating complex and dynamic environmental challenges
(Elsevier B.V., 2016)Complex social-ecological problems need sustained interdisciplinary engagements across multiple disciplines, yet academic offerings continue to reflect disciplinary silos. To address this, a five-year program, within a ... -
Invasion, alien control and restoration: Legacy effects linked to folivorous insects and phylopathogenic fungi
(Ecological Society of Australia, 2016)Invasive alien trees increase native tree stress and may increase attack by herbivores and pathogenic fungi. Alien tree removal should ameliorate such impacts. Here we compared the levels of damage by phylopathogenic fungi ... -
Invasive Australian Acacia seed banks: Size and relationship with stem diameter in the presence of gall-forming biological control agents
(Creative Commons Attribution Licence, 2017)Australian Acacia are invasive in many parts of the world. Despite significant mechanical and biological efforts to control their invasion and spread, soil-stored seed banks prevent their effective and sustained removal. ... -
A landscape-scale assessment of the long-term integrated control of an invasive shrub in South Africa
(Springer Science+Business Media B.V., 2010)The control of invasive alien plants often involves the integration two or more approaches, including mechanical clearing, the application of herbicides, burning, and biological control. More than one species of invasive ... -
A landscape-scale assessment of the long-term integrated control of an invasive shrub in South Africa
(Springer Science+Business, 2009)The control of invasive alien plants often involves the integration two or more approaches, including mechanical clearing, the application of herbicides, burning, and biological control. More than one species of invasive ... -
Linking functional traits to impacts of invasive plant species: a case study.
(Springer, 2015)Our understanding of the link between plant functional traits and ecological impact of invasive alien plant species is fragmentary and the mechanisms leading to impacts are poorly understood. Moreover, current knowledge ... -
Linking research to management:Restoring fynbos riparian vegetation following alien plant invasion
(2008)Following global trends, invasive alien plants are becoming an increasingly large problem in South Africa where growing evidence links invasive alien plant transformation to declines in ecosystem integrity and services. ... -
Links between lateral vegetation zones and river flow
(Springer, 2015)Plant species are known to be distributed on river banks in a sequence of community zones from the water’s edge to the outer riparian area. The interplay between flow and landscape is thought to drive the existence of these ...
