Notes

Abstract: With the basic information of successive measurements on permanent plots in a tropical forest with seasonal flooding, specifically the Caparo forest, Barinas state, parameter values are estimated for the FACET model, an extension of the gap model ZELIG. Much of the effort in this model had focused on the water balance in the soil as a primary constraint on forests. However, the model did not consider waterlogging stress, so in this paper a new tree species response is developed to account for the range of tolerance to this stress. Given the large number of species (89), the most representative species were selected by using the Importance Value Index (IV200), which relates the relative basal area and relative density. The species included were those with higher IV200 in descending order to reach a cumulative 75%. The remaining species were grouped according to light requirements and maximum tree height, considering the palms as a separate group. The results obtained in the simulation of the species basal area show a very good fit with respect to those observed in permanent plots in both levees and depressions, but not in transition areas. As for the various global parameters the results shows that, in general, are within expectations for levees and transition areas but not in depressions where the basal area is lower than observed.
