| Floristic-structural analysis of spontaneous little forests in the J. F. Villarino park (Santa Fe, Argentina). The anthropization process in the Pampean grassland has brought about an increasing presence of trees. In this study we analyzed the structure and composition of little forests which have resulted from the spontaneous multiplication of tree species in the J. F. Villarino Park, in Zavalla, Province of Santa Fe, Argentina. Using a plot sampling method, individuals were counted to determine density per species in the upper and treelets strata. Height and DBH of individuals in the upper stratum were recorded. Abundance-coverage of herbaceous and woody species saplings was estimated in the lower stratum. Soil humidity and ground-level light intensity... |
