Datça peninsula has a limited water budget due to its geographical structure. Although many studies have been carried out to protect water resources, no study has been conducted on some specific plant species' excessive water consumption for the Datça region. The study identifies and evaluates the negative impacts of Tamarix spp (Tamaracaceae) across the coastal landscapes of Datça. As an invasive alien species, initially used as a short-term solution to flooding and increasing soil nutrients, Tamarix spp has more adversities than the anticipations held during its introduction. Tamarix plant has compromised several ecosystems hence rendering it an extremely repulsive plant that requires termination. The study utilized literature to garner relevant information regarding the topic and its associates with the ecological systems and the overall environment. The study points out that Tamarix is responsible for water scarcity, species displacement, fire hazards, inhospitality of riparian areas, and altered soil systems. Further, the study argues that control measures have been adopted to terminate and reduce the risks of Tamarix. Overall, this study underlines the requirement of lowering the depletion rate of the underground freshwater source by preventing the excessive water consumption of future threat, Tamarix parviflora trees, which start from the coastal regions and spread to the inner areas of Datça.
