Impacts of logging on the vegetation of the forest management unit (UFA) Ipendja, Likouala Department

The estimation of the impacts of forestry operations, in particular on felling, logging and in timber yards, takes place in the Republic of Congo, more precisely in the Department of LIKOUALA, UFA IPENDJA of the Annual Cup 2020 Plate. its realization, forestry equipment was necessary. The results were processed using Excel 2013 software to achieve the expected results. For 1,149 trees felled, a useful surface area of ​​277,292.05 m2 had to be degraded, or 27.73 ha. The damaged young stems of the future were estimated at 827 stems destroyed during logging operations. These destroyed stems are represented by diameter class (I, II, III, IV, V and VI) and according to species (Main, secondary and others). When the skidding tracks were opened, we recorded 1,610 stems destroyed depending on the type of skidding track. For the main tracks, we observed a workforce of 1193 rods destroyed, while on the secondary skidding tracks we have 25.90% of the rods destroyed, corresponding to a workforce of 417 impacted rods. Five (5) parks are recorded with an average park length of 62.22 m, while 48 m represents the average park width. The impacted area is approximately 2.7 ha. The damage to the residual stand resembles the damage from road construction and the stems were uprooted, broken or debarked. For this operation, an exploitation damage rate of 33.94% on the initial stand for a sample of 1.5 stems / ha.
