Abstract :
- Floristic and forest structural analyses were
carried out to determine the impact of charcoal
production in a community-managed forest in southeastern Senegal. The results showed that at present
Missirah Forest shelters 62 species belonging to 18
families and 42 genera. The structural parameters
(diameter at breast height, tree density, stem density,
Lorey height and basal area) were found to be
significantly different among the vegetation types
encountered in Missirah Forest (p < 0.05), and the highest
values was observed in gallery forest. From 2002 to 2013
the species richness decreased whatever the vegetation
type as well as the species evenness. This decrease
observed is confirmed by the trend of Shannon diversity
index. The K-mean of the Importance Value Index (IVI)
identified three classes: species with improved, declined,
and relatively stable IVI. The parameters analysed for the
recovery of the forest with the exception of stem density
showed significant difference after the rotation period
indicating a non-replenishment of the resources. This
study showed that the conditions under which the forest
is managed currently do not constitute a sustainable
response to deforestation and degradation induced by
charcoal production. We recommended a revision of the
management plan and an enforcement of the strict
adherence to the technical prescriptions of the
management plan.
