The soil-litter system is the natural habitat for a great variety of organisms, which differ in size
and metabolism and perform various ecosystem services and are involved in key functions in
both natural and tillage systems. The objective of our study was to determine the distribution of
meso and macrofaunal communities in soil and litter with time in four land cover: Acacia
auriculiformis, Mimosa caesalpiniifolia, pasture and naturally secondary forest, as a model for a
self sustaining system. To evaluate the degree of soil fauna responses to forestry plantations
(tillage), the index V (indices of change) was used: V = (2DFP / DFP + DNF)-1, where: DFP =
density of soil fauna in forestry plantations and DNF = density of soil fauna in natural forest (NF).
The index V ranges from -1 (organisms occurring only under NF) to +1 (organisms occurring
only under DFP) and with 0 indicating equal density under both forestry plantations and natural
forest systems. All categories of inhibition or stimulation of soil fauna growth were found in all
sites. Inhibition or stimulation of organisms was influenced by season and soil components (soil
and litter). In general, forestry systems contain approximately more than 50% of stimulated
organisms. In drier season inhibit and stimulated organisms were similar in soil of forestry systems
and more than 50% of organisms in litter were stimulated. In rainy season about 50% of organisms
in litter and more than 50% in soil were stimulated. The forestry systems have a beneficial effect
on the soil and litter faunal communities, and could be considered as a conservation system for
soil fauna.
