A study of the natural regeneration of woodyspecies under isolated bushes in a sector of northeast of Ibera Macrosystem ispresented. The aim of the study was to evaluate the nurse effect of shrubs andstructural parameters of regeneration. We show that the presence of isolatedshrubs is fundamental to establish regeneration and that Ilex dumosa var. guaranina, Miconia chamissois, and Ocotea lancifolia promoted theirabundance and richness. The regeneration involved 21 species, but was mainlystructured by Miconia chamissois,Ilex dumosa var. guaranina, Citronella gongonha, and Myrsine parvula. The resultsindicate that Ilex dumosa var.guaranina was the most abundant solitaryspecies and one of the best to regenerate under these conditions. While thisshrub may constitute the initial stage in the formation of more or less largeforests fragments, we suggest that the abundance of Ilex dumosa var. guaranina in this kind of primary woodysuccession prompted the expression ?ka?a mirĩ? (the incipient forest), a guaraniname of this species.
