Species diversity, richness, and conservation status of Pteridophyta in the karst ecosystem of Donorejo Forest, Kaligesing, Purworejo, Indonesia. Intl J Trop Drylands 7: 16-25. Pteridophyta is often used as an environmental bioindicator. It can be found anywhere because of its cosmopolite ability. Karst ecosystem is one type of Pteridophyta habitat and roles as a pioneer plant. This study aims to determine Pteridophyta's biodiversity and conservation status in Donorejo Forest, Kaligesing, Purworejo, Central Java, Indonesia. The data collection of Pteridophyta species was carried out by survey method. Furthermore, the species found were analyzed using the Shannon-Wiener species Diversity Index (H'), Margalef Species Richness Index (Dmg), and Evenness Species Index (E). The research found 1387 individuals from 14 families and 34 species. Then, from the analysis that has been carried out using the calculation of tree indices, the following results are obtained; Shanon-Wiener Index (H') = 2.53, Margalef Species Richness Index (Dmg) = 4.56, Evenness Species Index (E) = 0.72. Selaginella plana (Desv. ex Poir.) is the most dominant in the area. From its conservation status, there are two species in LC (Least Concern) under IUCN conservation status, namely Pteris vittata L. and Sphaeropteris glauca (Blume) R.M.Tryon., while the rest are in NE status (Not Evaluated). Moreover, the CITES found one species under Appendix II status, S. glauca. Those biodiversity indices showed that Donorejo Forest has a stable, productive, and complex ecosystem with moderate biodiversity, a high value for Margalef Species Richness Index (Dmg), and an Evenness Species Index (E). At the same time, it faces threats from dominant species and local community activity. This study result can be used for diversity assessment, especially karst land ecosystems, and for further research to make the appropriate conservation strategy.

Ecotourism development as a community-based conservation effort in Ayah Mangrove Forest, Kebumen, Central Java, Indonesia. Asian J For 7: 37-44. The mangrove ecosystem is a transition ecosystem between terrestrial and marine zones affected by tidal waves, water inundation, and high saline water and soil. Mangrove forest plays an important role in physical, ecological and socio-economic aspects. One potential function of mangrove forests from the socio-economic aspect is ecotourism. Ayah Mangrove Forest in Ayah Village, Kebumen District, Central Java Province, Indonesia, has the potential to be developed as a mangrove-based ecotourism area that combines the objective of income generation and mangrove conservation. This research was conducted to examine the conservation and ecotourism efforts by the people of Ayah Village and to assess the local community's perception of the development of mangrove-based ecotourism. The research was conducted in November 2022. Primary data were collected using field observation and interviews with 100 respondents aged 17-60 years using the snowball sampling method, while secondary data were collected using a literature review. The results showed that efforts to protect the Ayah Mangrove Forest area included establishing zones for protection, rehabilitation, and utilization of the mangrove forest. There are also mangrove rehabilitation efforts that involve the community in the form of the establishment of nurseries, mangrove planting, and maintenance of planted seedlings. The local community also carry out garbage cleaning program and public outreach. Besides the conservation aspect, Ayah Mangrove Forest is also utilized for ecotourism objects that generate income for the local community by selling tickets, boats, foods, beverages and souvenirs, tour guides, and parking attendants. Most of the local community has good perceptions and agreed on the development of Ayah Mangrove Forest as an ecotourism area. They are willing to be involved in ecotourism planning and development activities. The community agreed to participate in tour guide activities, selling souvenirs, providing homestays, and participating in ecotourism counseling. Most of the local community has also agreed to form a mangrove conservation community to maintain the sustainability of mangrove forest ecotourism. Nonetheless, support from the government is required, especially in the promotion and rehabilitation programs in the ecotourism development of Ayah Mangrove Forest.
