The study on the assessment of the impact of forest operations on vegetation is carried out in the Gouongo Forest Exploitation Unit (UFE) located in Komono District, Lekoumou Department, part of the Southern Forest Sector. The whole of the UFE is covered by the dense rain forest of the Guineo-Congolese region, except for a few rare non-forest areas: savannas, cultural complex, anthropised zones, stream beds and bare ground. The hydrographic network is relatively dense. Unfortunately, harvesting of forest products for the benefit of loggers is often accompanied by direct or indirect environmental impacts, resulting in the modification or disappearance of biodiversity. The methodology recalls the evaluation of the measures of the destroyed areas by counting the number of damaged stems compared to the two operations, in particular the felling and skidding of the woods in the forest. The results of this assessment show that there are differences in the average areas affected by the felling of trees, which is 2383.08m2, resulting in a number of damaged young stems of: 990 broken stems, 112 uprooted stems and 168 debarked trees, ie a total of from 1270 feet. For the skidding operation, the average area destroyed was 33329 m2 with a number of damaged stems of: 372 including 82 uprooted stems, 140 broken stems and 150 stems with bark. It can be seen that the harvest rate at the level of the slaughter is 1.84 feet per hectare in this 2017 Annual AAC. It is thought that if this rate had reached or exceeded the Exploitation standard. Reduced Impact Forest (EFIR) estimated at 2.5 feet per hectare, then damage to vegetation and the number of damaged young stems would still be enormous.     

Key words: logging, slaughter, skidding, vegetation, areas, damaged stems
