Predicting invasion dynamics of four alien Pinus species in a highly fragmented semi-arid shrubland in South Africa

The Role of Environmental Factors in Promoting and Limiting Biological Invasions in South Africa

“…Exploring this in more detail for invasive tree species that are also commercially important crops in South Africa, Rouget et al (2002) found that the distribution of invasive stands was largely explained by climatic factors, even when key factors that are known to drive invasions at the landscape scale, such as propagule pressure from plantations and landuse, were included in models. In a study at the landscape scale, Rouget et al (2001) found soil pH to be the most important variable for explaining invasive pine distribution in a highly fragmented semi-arid shrubland. Similarly, Goodall et al (2011) showed that the presence of the herbaceous Pompom Weed in the grasslands of Gauteng Province is affected by environmental factors such as rainfall, topography, and soil texture at large spatial scales.…”

Extreme climate conditions limit seed availability to successfully attain natural regeneration of Pinus pinaster in sandy areas of central Spain

“…Pinus pinaster plantations were established in the southern hemisphere (mainly in South Africa and Australia) where it can escape from plantations and spread into native ecosystems (Rouget et al, 2004). It is for this reason that Pinus pinaster has been considered one of the world's worst invasive tree species (Lowe et al 2004).…”

Local spread of an exotic invader: using remote sensing and spatial analysis to document proliferation of the invasive Asian chestnut gall wasp

“…Hyperspectral images, GPS collected data and GIS have been used to locate and map invasive plants in California (Underwood et al 2003), and combined with spatial regression analysis, to identify the parameters affecting their spread (Dark 2004). Remotely sensed data and GIS have also been used to understand invasions by naturalized horticultural imports (Lemke et al 2011) and woody plants (Rouget et al 2004).…”

Carr. (Clark et al 2012).…”
