Occurrences of the two invasive plant species were sampled using an android-based application and a GPS (Global Positioning System) device. using occurrence data, then applied a species distribution model to identify where suitable habitats occur under current and projected climatic scenarios under Representative Climate Pathways (R) 2.6 and 8.5. This study mapped the current distribution of Acacia reficiens and Opuntia spp. Invasive species, however, threaten this biodiversity. Habitat heterogeneity has led to a diverse number of plants and animals. Kenya is composed of diverse geographic regions and is heavily impacted by climatic variability. Effective policies are therefore needed to prevent an increase in the significant negative impacts caused by IAS including those that have a limited distribution. The most applied methods of managing Opuntia are mechanical and chemical methods that are unsustainable and labour-intensive at large scale. Introduction pathways are largely intentional for ornamental purposes but unintentional at a local scale through escape from gardens and natural dispersal. Invasion is mainly attributed to changes in land use and consequent land degradation. These species have the same habitat preferences, physiological traits, negative impacts, introduction pathways and management options. Seven invasive species of Opuntia are present in the country with the most abundant (O. This paper, therefore, provides an overview of the interacting factors that influence its invasion in Kenya in terms of species diversity, pathways of introduction, negative impacts and the effectiveness of regulations and control measures. However, comprehensive information on the status of invasion in the country is lacking, which is crucial for developing strategies for prevention and management. Opuntia (prickly pear cactus) is one of the most widespread and naturalized in the arid and semi-arid areas of Kenya, with extreme effects on rural livelihoods and the environment.

Invasive alien species (IAS) are among the leading threats to biodiversity, food security and human well-being.
