“…The region is characterised as having montane grasslands and ericaceous shrublands, as well as some patches of montane woodlands and moist evergreen forests in lower-lying parts. Additionally, the Chimanimani is part of the Eastern Afromontane Biodiversity Hotspot (Shah et al 2018) and recently it was declared a Biosphere Reserve (United Nations Educational, Scienti c and Cultural Organization (UNESCO) 2022). The physical setting of the phytoregion favours plant diversity with more than 1000 plant species, of which 60 are endemic and are found mostly in the Chimanimani Mountains, Nyanga area, and Chirinda Forest.…”

Biological invasions can have major social-ecological consequences for local communities across the world. However, the dimensions (characteristics, infestation and socio-ecological impacts) of emerging invasive alien plants are often less well known but urgent information is needed to guide policy and management. In light of this, this paper assesses the social-ecological impacts of Vernonathura Polyanthes an emerging invasive alien plant, in a Zimbabwean upland landscape which supports conservation and livelihoods. Informed by exploratory participatory qualitative methodologies we discussed the socio-ecological and economic implications (benefits and impacts) of Vernonathura Polyanthes and how it is managed in the eastern parts of Chimanimani, Zimbabwe. We found that there are nuanced perspectives of this invasive tree among different socio-economic groups in the region who have different experiences of living with Vernonathura polyanthes. Some are embracing it for apiculture, firewood, and ethnomedicine, on the other hand for others the tree is negatively affecting key livelihoods (crop farming, pastoralism and tourism) that are common in the region. Local people also identified that Vernonathura Polyanthes is associated with ecological impacts that include loss of biodiversity, promoting pests and negatively affecting watersheds and associated water security. Mixed experiences on the plant are leading to different management practices, in turn inducing some conflicts among various actors. Based on our findings we suggest more should be done to better manage this invasive plant in the region before negative impacts become too great, particularly in the protected areas in the region.

“…In the last 15 years this has changed to an upsurge in botanical exploration and discovery as reported in Cheek et al (2018c). Since that date Olinia chimanimani T.Shah (Shah et al 2018) from Chimanimani and Eriolaena rulkensii Dorr in the Dombeyaceae (Dorr & Wurdack 2018) from near Pemba in NE Mozambique have been published. The latter is the first time that a member of this genus, previously thought restricted to Asia, has been recognised in continental Africa.…”

Summary Cola cheringoma is described from the limestone gorge forest of the Cheringoma Plateau in Sofala Province of Central Mozambique. Tentatively treated previously as C. clavata Mast., it differs in being restricted to limestone substrate, the leaves drying white-green below (not on sandy soils, drying dark grey-brown). The tepal number of female flowers is 5 (not (5 –) 6), staminode number 5 (not 8), and the indumentum of the outer perianth covers only 50 – 60% of the surface with two distinct hair classes (not 100% coverage with a single hair type). The species is assessed as EN B2ab(iii) using the IUCN 2012 standard due to threats from the low number of locations, quarrying, and habitat modification. The Cola species growing in forest on limestone in tropical Africa are mapped and reviewed with respect to their status as obligate or facultative calcicoles, and with respect to their probable evolutionary origin. Based on morphological characters, adaptation to limestone habitats has probably occurred at least four times in the genus. Forests on limestone are rare and threatened in tropical Africa: only thirteen locations are known with certainty: these occur in Kenya (10 locations), Tanzania (2 locations) and Mozambique (1 location).

Biological invasions can have major social-ecological consequences for rural communities across the world. However, the dimensions (characteristics, infestation and socio-ecological impacts) of emerging invasive alien plants are often less known and urgent information is needed to guide policy and management. In light of this, this paper assesses the social-ecological impacts of Vernonanthura polyanthes, an emerging invasive alien plant found in a Zimbabwean upland landscape which supports conservation and livelihoods. The paper employs qualitative methods—community mapping, time series analysis, and key informant interviews—involving individuals from diverse socio-economic backgrounds, to examine the socio-ecological and economic implications of V. polyanthes and its management in Chimanimani, Zimbabwe. We found that there are nuanced perspectives regarding this invasive alien plant among different socio-economic groups in the region who have different experiences of living with V. polyanthes. Some are embracing it for apiculture, firewood, and ethnomedicine while, on the other hand, some see the tree as negatively affecting key livelihoods (crop farming, pastoralism, and tourism) that are common in the region. Local people also identified that V. polyanthes is associated with ecological impacts that include loss of biodiversity, promoting pests, and negatively affecting watersheds and associated water sources. These mixed experiences concerning the plant are leading to different management practices, in turn inducing some conflicts among various actors. Based on our findings, we suggest more should be done to better manage this invasive alien plant in the region before negative impacts become too great, particularly in protected areas.
