Invasive alien plants (IAP) affect rural livelihoods in both positive and negative ways, yet few studies examine how these impacts are distributed across households and contribute to vulnerability. This study assessed Impacts of Lantana camara invasion on livelihoods: Household perceptions from the Kavango Zambezi Transfrontier Conservation Area, Zimbabwe. We conducted 300 household surveys and two focus group discussions with...

Aim We examined differences in the architecture of A frican and A ustralian savanna trees. We sought to attribute variation in tree architecture to current environments, wood density and phylogeny, and thereby elucidate the relative importance of biogeographic idiosyncrasies versus current factors in underpinning architectural differences. Location A frica and A ustralia. Methods We compiled canopy diameters and stem diameters...

Summary We aimed to explore the farm scale effects of three landuse types, communal grazing, wildlife management and commercial cattle farming, on the woody vegetation of a semiarid savanna. Location The study farms were located within a single bioclimatic zone in semiarid savanna, South Africa. Methods The species composition and structure of woody vegetation on three farms of each of three landuse types were sampled. Results...

Woody community phenology was studied in the central lowveld, South Africa, over a twelve month period at three sites along a rainfall gradient, with both toplands and bottomlands sampled at each site. Each month, individual plants, in replicated samples, were scored into a number of categories describing their phenological state. Position on the rainfall gradient influenced: (1) onset and magnitude of leaf emergence, (2) onse...
