ABSTRACT: The realization of two management inventories in 2003 and 2020 on the
same forest concession made it possible to characterize the floristic
composition and to describe some structural parameters on three sites
established according to the period of exploitation. Due to the change in the
orientation of the lines, it was noted that respectively 82 and 85 species from
the first inventory are not found in the second and inversely. A total of 311
species were identified in 2003, compared to 314 in 2020. The density varies
from 111 to 140 stems/ha for all the individuals, 19 to 25 for the main species
and 15 to 20 for the most exploited species. The decrease in the basal area
between the two phases of 12% for all the species and 13% for the main species
on the site exploited before the first inventory indicates a persistence of the
disturbance for years after logging. It is proposed to supplement the
management plans decisions with annual measures based on more complete
inventories and to ensure the application of reduced impact logging measures.
