The study was carried out to evaluate and examine the impact of timber harvesting on residual tree species in Edo State, Nigeria. The reconnaissance survey of the forest reserve was used to identify logging activities in the study. Furthermore, questionnaire was used to retrieve information from fifty (50) professional tree loggers to collect information on the demographic characteristics of the loggers and to know the major causes of damages to the trees and seedlings during felling operations and precautions taken to mitigate such damages. Findings showed that Bosquieaangolensis had the highest frequency among the damaged species. The total volume of damaged trees per hectares was 711.04m3. Results also showed that among the loggers, 7.6% had no formal education, while, 23.7% had over ten years of working experience. It also revealed that the majority of the operators 92.4% still required additional training on effective felling operation. The timber industry has grown beyond the forest regeneration capacity with poor conventional harvesting practices, and unabated degradation of the forest ecosystems during logging operations. The study revealed that major damage is done to the residual trees during the felling and transportation of the targeted tree species. There is  need therefore, for adequate training and or retraining, monitoring, and supervision of effective felling operations to improve their competencies and further decrease the destruction of the ecosystem during logging activities.
