Ecology and Reproductive Biology of Calotropis procera (Aiton) W.T in some parts of Mopani District Limpopo Province. . .https://univendspace.univen.ac.za/handle/11602/3021MSc (Botany)Department of Biological SciencesPlant species play a crucial role in maintaining the normal functioning of various ecosystems. However, native species often face decline or extinction due to alien species' invasion and its detrimental impact. One such invasive species, the widespread shrub or medium-sized tree Calotropis procera (Aiton) W.T., is encroaching upon several villages and roadside areas in the Limpopo Province of South Africa, where it has been classified as an invasive species. This shrub, ranging from 2.5 to 6 meters in height, has proliferated across various regions of South Africa. This study was conducted in six villages within the Mopani District, Limpopo Province, to investigate the ecology and reproductive biology of Calotropis procera (Aiton) W.T. The findings of this study are critical for devising strategies to manage or eradicate these invasive species in affected areas. Researchers observed and counted the number of Calotropis procera (Aiton) W.T plants alongside roads and villages, measuring the distances between these plants and their nearest neighboring species to assess potential competition. The present study also involved monitoring the phenological patterns of Calotropis procera (Aiton) W.T, including the timing of flower, fruit, and seed production, as well as seed dispersal mechanisms. This information is vital for determining the optimal periods for eradication or control efforts. The distribution pattern of Calotropis procera (Aiton) W.T. was analyzed using the Clark and Evans (1954) method, and phenological data were collected through photographic documentation at each site. The extensive spread of Calotropis procera (Aiton) W.T. is attributed to its prolific seed production, wind-dispersed seeds, and stress tolerance, enabling it to thrive in various environments. The study suggests the best time to remove Calotropis procera (Aiton) W.T. plants is between February and April before they produce fruits. Understanding the impact of Calotropis procera (Aiton) W.T. on the local ecosystem is essential for developing effective management strategies. Overall, this study provides a comprehensive understanding of Calotropis procera (Aiton) W.T.'s ecology and reproductive biology and offers valuable insights into potential strategies for managing and eradicating this invasive plant species.1 online resource (viii, 62 leaves): color illustrations, color mapsenUniversity of VendaCalotropis procera (Aiton) W.
