ABSTRACT
Invasive alien species (IAS) are non-native species that cause, or have the potential to cause, harm to the environment, economies, or human health. The threat to biodiversity due to invasive alien species is considered second to that of habitat loss. The focus of the 2 study was on one of the invasive alien plant Datura innoxia. The study was conducted in the City of Windhoek, the capital of Namibia, situated at 22.56°S, 17.09°E. The aim of the research project was to study the distribution, abundance and reproductive status of the invasive alien D. innoxia in the City of Windhoek. The information gathered will contribute to the knowledge and understanding of weedy invasive aliens in the City. Data was collected 121, 25 0000 m 2 grids that were randomly sampled in the City. The City of Windhoek grided map was used to locate the specific grids. The grids were subdivided into sixteen 15625 m 2 plots to ease observations. In each plot, all D. innoxia were recorded including their height, crown width, number of capsules and number of flowers. Within a radius of one-meter, other organisms and plants associated with D. innoxia were also recorded. The presence and absence of other plant species found in the plots were recorded. ArcView 3.2 was used to develop the distribution map and SPSS 15 was used to analyze the data.
