The construction of toll roads in Indonesia significantly changes land use, highlighting the need for effective environmental management. A major concern is the loss of endemic habitats, which can lead to biodiversity extinction. This research analyzes the diversity and conservation status of flora and fauna in the affected area, using vegetation analysis for flora and the point count method for fauna. The results of the vegetation analysis indicate that the species composition includes 12 species from the Fabaceae family, 7 species from Asteraceae, and 5 species from Moraceae. The highest Importance Value Index in the tree stratum is attributed to Swietenia macrophylla. The highest flora diversity index is found in the herbaceous stratum (H’ = 3.25), while the diversity indices for other groups are as follows: dragonflies (H’ = 1.24), Lepidoptera (H’ = 3.26), avifauna (H’ = 2.25), and herpetofauna (H’ = 2.07). Regarding the conservation status of flora taxa, Dalbergia latifolia and Swietenia macrophylla are classified as vulnerable, while Tectona grandis is considered endangered. In the Lepidoptera group, Spalgis epius and Mycalesis horsfieldii are categorized as endangered, while Euploea mulciber and Orsotriaena medus are vulnerable. Rubigula dispar and Acridotheres javanicus are classified as vulnerable species within the avifauna group. Although the construction of the toll road will involve clearing part of the forest that includes Tectona grandis and its associated fauna, this impact is deemed manageable because no species require specialized habitats. For reforestation efforts, it is recommended to plant Ficus spp., Swietenia macrophylla, Dalbergia latifolia, and Tectona grandis.
