Impact of invasive alien plants Gutenbergia cordifolia and Tagetes minuta on native taxa in the Ngorongoro crater, Tanzania
Ngondya, Issakwisa; Munishi, Linus (Elsevier, 2021-09)Understanding the ecological impacts of invasive plant species on the native communities and identifying native plant species that co-exist with invasive plants are important for planning the effective control and restoration ... -
Invasive plants: ecological effects, status, management challenges in Tanzania and the way forward
Ngondya, Issakwisa; Treydte, Anna; Ndakidemi, Patrick; Munishi, Linus (Journal of Biodiversity and Environmental Sciences (JBES), 2017-03-31)Over decades invasive plants have been exerting negative pressure on native vascular plant’s and hence devastating the stability and productivity of the receiving ecosystem. These effects are usually irreversible if ... -
Managing invasive plants through a nature-based approach in complex landscapes
Ngondya, Issakwisa; Munishi, Linus (Elsevier Ltd., 2022-02-09)Invasive plants are establishing in many protected areas where use of synthetic herbicides is prohibited. We introduce a nature-based approach (NbA) as an alternative to controlling invasives. The integration of NbA into ... -
