This study on the characteristics of
the vegetation (herbaceous and woody) Gadoudhé course was
conducted in the rural area of Fabidji (Niger). Within 126 plots that have been set through 4 transects.
Aligned quadrat points method allowed
taking an inventory of the herbaceous. The herbaceous
biomass was evaluated by the method of the full
harvest. After making the list of woody species, the measures on dendrometric
parameters were
conducted. The regeneration of the species has been
appreciated by the count of live and dead
discards. 37 were inventoried. Among these 27 species
are herbaceous plants. The most represented
families of grasses are the Poaceae, Fabaceae,
Amaranthaceae and the Convolvulaceae. Residual
biomass is 471.1 kg DM/ha of « qualified » fodder. What
gives an estimated carrying capacity to 0.041 TLU/ha/year?
As for the wood, they are represented by 10 species,
especially represented by the Combretaceae. The
structure of the settlement shows average individuals of height and diameter.
Basal area was evaluated to 0.01 m2/ha at a
density of 13.75 individuals per hectare. The regeneration of seeding presents a density of releases per
hectare 1020.91.
The results obtained highlight the need to think about
a layout of the route to ensure its sustainability.
