Community Perceptions on the Transformation of a high-altitude Grassland Through Invasion by Leucosidea sericea at Vuvu, South Africa

We assessed perceptions of Leucosidea sericea, a woody plant that is increasing in density such that it may threaten rangelands among agro-pastoralists whose livelihoods rely on livestock (56%) and crop farming (36%) in Vuvu, Eastern Cape, South Africa. Using semi-structured questionnaires, we asked 198 respondents about the spread of the species in the last few decades, and its impact on the availability of graze for livestock. Responses indicated that L. sericea started spreading in the 1950s, with marked increases in 2011-2020, particularly in the mountainous areas used for grazing as well as by rivers and village residences. Respondents suggested that livestock were the main biological agent of seed dispersal, and livestock ownership had increased dramatically in recent years, with a preference for sheep (a minimum of 120 per household). Overall, respondents indicated that L. sericea encroachment negatively affected their community.
