Large areas of the Atlantic coastal rainforest have been deforested in the past mainly for
agricultural purposes, especially cattle grazing. However, many of these areas are currently underutilized or degraded by overgrazing or intensive use. In the coastal region of Paraná, smallscale buffalo grazing has led to considerable local soil degradation and, with the abandonment of the pastures, the exotic Brachiaria sp. grass spreads and becomes a problem for the restoration of these pastures and for alternative uses, such as palmito (heart-of-palm), native forest regeneration or forestry activities. Therefore, to evaluate the potential of various native tree species in the restoration of these pastures, a trial was established in 2002 at a private reserve of the Sociedade de Proteção da Vida Silvestre (SPVS), near Antonina. The experiment was set up in 4 blocks with 3 replicates and 5 native species, planted in plots of 10 x 16 m. For the present study, two tree species were chosen, both legumes: ingá (Inga sp.) and capororoca (Myrsine sp.). The effect of these treatments on the soil fauna abundance and diversity was investigated using the standard TSBF method (25 x 25 cm blocks) but only in the top-soil horizon
(0-10 cm), due to a high water-table. Two samples were taken per plot, with a total of 18 samples in the Myrsine sp. and 14 in the Inga sp. Four earthworm species were found, two exotic megascolecids, Pontoscolex corethrurus (Müller, 1857), and another yet unidentified ocnerodrilid. Total macrofauna group diversity was higher in the Myrsine (11) than Inga (7) sp. plots, and total abundance was also slightly higher (644 vs. 483 indiv. m-2, respectively). Earthworms represented >80% of total abundance, and P. corethrurus predominated, representing 85% of all collected earthworms (973 individuals, including 33 cocoons). The other most abundant fauna were snails, beetles and Millipedes, representing each <10% of total abundance. Principle components and redundancy analyses showed a separation of the sample sites based mainly on soil moisture and earthworm (especially P. corethrurus) abundance, both of which tended to be larger in
Myrsine sp. plots. MenosLarge areas of the Atlantic coastal rainforest have been deforested in the past mainly for
