One of the symbols of biodiversity in Indonesia’s lower montane forest is Petungkriyono. Due to its location adjacent to populated areas, it has an impact on the survival of the local flora and animals in the Petungkriyono forest area. This study aims to provide a preliminary description of the plant and animal species found in the Petungkriyono forest area. A synoptic review method to Petungkriyono biodiversity publications was used in the writing of the article. The study’s findings revealed that the Petungkriyono forest region consisted of 168 species of wildlife and 204 species of plants. Certain species are endemic, while others fall into the IUCN conservation status categories of Vulnerable (VU), Endangered (EN), and Critically Endangered (CR). It is also a certain that a number of species will be added to the CITES Appendix list in 2023 (Appendices I and II). The demands of population expansion and poaching are the current issues, burdening the forest areas that are already there. High biodiversity, stunning scenery, and the presence of indigenous knowledge can all present opportunities for ecotourism. Immediate implementation of conservative measures, such as maximizing current opportunities to preserve biodiversity, is essential
