vegetation in the protected areas in Botswana. Phytosociological methods include going to the field to study and collect vegetation data, whereas remote sensing methods involve using satellite imagery to study and map the vegetation. The current study used Google, ScienceDirect, and Web of Science to search for keywords such as phytosociology, remote sensing, national park, game reserve, plant community, classification, mapping, conservation, protected areas, Botswana. English literature published from 2000 to 2020 from peer-reviewed journal articles, books, edited book chapters, electronic academic thesis, and technical reports were selected for review. The full texts of the studies were downloaded, and the information on the study area, study objective, satellite imagery used, and classification type used to map the vegetation was extracted.
