La Reunion tuvo como objetivos principales: presentar un balance de lo que han sido las experiencias y resultados de investigacion en silvicultura de bosques naturales en los tropicos americanos y discutir sobre los factores que condujeron al exito o fracaso en la aplicacion de los varios metodos probados en diferentes tipos de bosque y condiciones socioeconomicas; discutir los aspectos biologico-ecologicos y tecnico-economicos criticos para la planificacion, diseno y aplicacion exitosa de la silvicultura en el manejo de bosques naturales; identificar y priorizar la investigacion silvicultural necesaria para el manejo de bosques naturales, atendiendo a las diferencias biofisicas y socioeconomicas de la region y las nuevas tendencias en el manejo de los bosques naturales; y definir mecanismos que contribuyan a mejorar la aplicacion y transferencia de resultados de la investigacion en este campo. |

Earthworm biostructures are widely accepted for their distinctiveness in term of soil structure,
organic matter availability or biological activities. However, while the determinism of earthworm
activities has been investigated since a long time, only few studies have reported data on the
spatial distribution of earthworm biostructures according to agricultural practices.
Therefore, many soil profiles corresponding to conventional tillage (CT) and no-tillage treatment
(NT) were thinly sketched according to the typology of soil morphologic features (physicogenic
and biogenic facies). Then, GIS tool were used (i) to quantify the areas of biostructures according
to the depth, (ii) to qualify the size and the shape of the facies (iii) and to detect their preferential
orientation.
This study showed that the area of biogenic facies clearly differed between 0 and 25cm, with the
significant highest value for NT treatment (25 to 35%) vs 10% for CT treatment. On the other
hand, the percent of biogenic facies that decreased gradually below 25cm did not differ
significantly between the agricultural treatments.
Facies of bioturbation was composed by a major part of cast aggregates assembling (B3),
dominated by welded casts (B3i), while the facies B1 (burrows) never exceeded 1% of the soil
profile.
The size of B3 facies could reach 80cm², but most of them (80%) were ranged between 4 and
20cm². In addition, the shape of the facies B3 appeared frequently circular, even if a contortioned
shape characterized often the welded casts assembling (B3i). In No-Tillage treatment, the impact
on earthworm activities of past ploughing was noticed by the oblique orientation for many facies
B3i between 10 and 25cm.
Our study showed that earthworm activities under the constraint of soil agricultural practices are
