Reconstructing 50 years of Opuntia stricta invasion in the Kruger National Park, South Africa: environmental determinants and propagule pressure
Many factors influence the spread dynamics and distribution of invasive alien organisms. Despite progress in unravelling the determinants of invasiveness and invasibility, robust, spatially-explicit predictive models for ...
Risk Assessment of Riparian Plant Invasions into Protected Areas
Protected areas are becoming increasingly isolated. River corridors represent crucial links to the surrounding landscape but are also major conduits for invasion of alien species. We developed a framework to assess the ...
What helps Opuntia stricta invade Kruger National Park South Africa: Baboons or elephants?
(IAVS; Opulus Press Uppsala, 2007)
Question: Is Opuntia stricta more frequent, and its patches larger, under trees suitable for baboon roosting? If so, does it mean that baboons are major dispersal agents and that plants established under these trees are ...
Ornamental plants as invasive aliens: problems and solutions in Kruger National Park, South Africa
(Springer Science+Business Media, LLC, 2008)
The most widespread invasive alien plant species in South Africa’s Kruger National Park (KNP) were either introduced unintentionally along rivers and roads, or intentionally for use as ornamentals. We examine the spatial ...
Defining optimal sampling effort for large-scale monitoring of invasive alien plants: a Bayesian method for estimating abundance and distribution
1. Monitoring the abundance and spatial structure of invasive alien plant populations is important for designing and measuring the efficacy of long-term management strategies. However, methods for monitoring over large ...
National parks impact and pathways database for plants
A database of potential impacts and possible pathways of introduction for alien plants in national parks in South Africa.
Patterns of alien plant distribution in a river landscape following an extreme flood
(Elsevier B.V, 2008)
The availability of suitable patches and gaps in the landscape is a crucial determinant of invasibility for alien plants. The type and arrangement of patches in the landscape may both facilitate and obstruct alien plant ...
Human population density explains alien species richness in protected areas
Understanding the drivers of biological invasions, across taxa and regions, is important for designing appropriate management interventions. However there has been no work that has examined potential drivers of both plant ...
Alien plant invasions in tropical savanna ecosystems: patterns, processes and prospects
Biological invasions affect virtually all ecosystems on earth, but the degree to which different regions and biomes are invaded, and the quality of information from different regions, varies greatly. A large body of ...
Threats to Paradise? Plant Invasions in Protected Areas of the Western Indian Ocean Islands.
(Springer, Dortrecht, 2013)
The islands of the Western Indian Ocean are well known for their unique biodiversity. However, much of the native habitat has been destroyed and the remainder is threatened by invasive alien species. In this review we ...
