Land use change in tropical regions has been characterized from forest to agriculture land or
grasslands. After this, the modified environment reduce theirs nutrients and then it is abandoned
by the farmers, like a bush old area (Acahual). The Acahual can be an important recovering area
for the future of the Forest dynamic. Comparisons between natural Forest habitats and disturbed
systems help us to gain insight into mechanisms leading to diversity changes by studying the
changes in habitat characteristics. The objective of this study was to know the effect of land use
change in macrofauna of soil (>2mm). We hypothesis that total macrofauna and every taxa
groups (Blattodea, Coleoptera, Diptera, Oligochaeta, Diplura, Hemiptera, Isoptera, Aranea,
Diplopoda, Hymenoptera, Isopoda, Miriapoda) will decrease in this order: Forest > Acahual >
Agriculture land > Grassland. The study area was in the mountain regions of Tabasco state in
Mexico (17° 30?N - 18° 30?N and 91° 00?W - 94° 00?W). Three different sites were selected with
two replicate each one: Forest-Agriculture (F-A), Forest-Grassland (F-G) and Forest-Acahual
(F-A). Three transect of 75m long with nine monoliths (four monoliths in the Forest, one in the
border and four in the modified ecosystem) were installed; the size of monolith was of 25 x 25 x
30 cm (TSBF, Anderson and Ingram, 1993) with a total of 54 monoliths per site. The soil
macrofauna of soil were divided in two layer: first layer from 0-10 cm and second from 10-30
cm. The abundance of macrofauna of soil in Forest was 1.3 times larger than the sum of the
modified environments. The first layer was significant higher in Forest (26.5 ± 3.6 individuals m-
2), Acahual (30.9 ± 7 individuals m-2) and Grassland (9.6 ± 2.1 individuals m-2) than the second
layer. Forest (20.0 ± 2.22 individuals m-2) and Acahual (23.3 ± 4.17 individuals m-2) were
significant larger than Grassland (7.7 ± 1.4 individuals m-2) and Agriculture land (9.9 ± 1.5
individuals m-2). The Acahual was larger (e.g. Coleoptera, Hemiptera, Aranea and Diplopoda)
than Forest and not significant differences (Blattodea, Oligochaeta, Isoptera, Hymenoptera and
Myriapoda) with the Forest. Therefore, the Acahual has an important function to restore the
original abundance of fauna. MenosLand use change in tropical regions has been characterized from forest to agriculture land or
