Community Awareness of Invasive Alien Plant Species in Ngorongoro, Manyara, and Tarangire Conservation Areas

Invasive alien species are a major driver of biodiversity loss, despite global, regional, and domestic efforts to address them. This study aims to assess community awareness and engagement in combating invasive alien plant species in Tanzania, using a cross-sectional questionnaire survey of 208 respondents. Eight villages around Ngorongoro, Tarangire, and Manyara ecosystems were surveyed using questionnaires to gather information on awareness of Invasive Alien Plant Species presence, affected areas, means of spread, harmful effects, and community involvement. Results show that over 65% of respondents were aware of Invasive Alien Plant Species, with impacts observed on farms and grazing lands. However, there was limited knowledge about specific harmful effects. Community involvement in combating Invasive Alien Plant Species was lacking, with minimal direct engagement from authorities and stakeholders. Control methods primarily involved burning and cutting, while biological and chemical approaches were less favored. The study underscores the need for enhanced community involvement and recommends greater collaboration between stakeholders to effectively manage Invasive Alien Plant Species and mitigate their impacts on ecosystems.
