Insects may respond to biotic (host, vegetative biodiversity, crowding, and nutritional) and abiotic (temperature, humidity, and light) challenges by increasing their metamorphic stages, survival, and rate of reproduction. This study's primary goal was to evaluate the biodiversity (insect and aquatic species) in Vietnam's Bac Kan province.In the province of Bac Kan, insects, and aquatic species were observed in the field for this study.
In all study sites in Bac Kan province (Ba Be Naional Park; Kim Hy Nature Reserve; Nam Xuan Lac Species and Habitat Conservation Area; and Thac Gieng Landscape), 11 insect orders were discovered, and Ba Be National Park had the largest variety of insect species compared to the other three study sites. In all research sites, the Coleoptera is the most abundant order of insects. In the province of Bac Kan, 29 aquatic species were identified for the purpose of species assessments. Although the Bac Kan province's insect and aquatic species are still rated well.
Overall, conservation efforts are still needed to ensure that they will survive in the future. This study will help the decision-maker and policy maker for the conservation and protection of biodiversity in the Bac Kan province.
