Abstract

Has been studied the influence of the laboured, bulldocer scalping plus full subsoiling, in the presence of characteristic species of the mesomediterranean siliceous soils shrubs of “the Andévalo” in Huelva. The study is set in the Council “Cabezas Rubias”, province of Huelva, on a Pinus pinea reforestation, eight years after the bulldocer scalping and subsoiling previous plantation labours, were done, the total shrub cover has been estimated and compared as the addiction of its specific covers in the situations: 1) Grown shrubs after the considered preparatory treatment; 2) Shrubs presence in close areas without reforestation, therefore without any preparatory practice for reforestation. From the statistical analysis, no relation was obtained in the total cover variable with the applied treatment, it can be concluded that the only species which reduces its presence (in a 65.56%) is Cistus ladanifer. The specific cover average representation increases in Erica australis (33.90%), Erica umbellata (84.01%) and in all the flora components from the “Other species” group, composed by Halimium ocymoides, Genista triacanthos and Lavandula stoechas. In this group, Genista triacanthos and Lavandula stoechas didn’t appeared in the testigo shrub, appearing with low representation after the reforestation labours studied.
