Critical Study on Characteristics of the Gadoudhé Course Vegetation in the Rural Area of Fabidji (Niger)

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.
