Mangrove forests are the habitat of various organisms, including Ferns plants. Ferns plants as plant communities in biodiversity have important ecological functions in the mangrove forest ecosystem. The objectives of the study were (1) to know the index of the diversity of Ferns plants (pteridophyta), (2) to determine the type of Ferns plant found in the mangrove forest of Wonorejo Surabaya, (3) to know the environmental parakeet of mangrove forest of Wonorejo Surabaya as the place of life of Ferns plant (pteridophyta). The research was conducted from March 2018 - June 2018 in Wonorejo mangrove Surabaya. This type of research is descriptive skin to obtain information about the diversity of Ferns plant species in terms of sporangium type, habitat and environmental factors that may affect. Samples were obtained from 5x5m plot of land at 5 research stations. The method used in this study is the method cruse with direct observation and explore each point of the location that can represent the types of ecosystems or vegetation in the area under study. The result shows that the diversity of Ferns plant species in the mangrove forest of Wonorejo Surabaya is said to be low in terms of diversity index because there are only 3 types of Ferns plants that consist of pteridaceae family, with Acrostichum aerum species, Acrostichum speciosum and Pytirogramma calomelanos. This is due to environmental factors that are less suitable as a place of life of Ferns plants such as habitat, temperature, humidity, light intensity and wind speed. The benefit of this research is to go to the ecosystem that is suitable with Ferns plant by adding the habitat for Ferns plant to live. © 2020 Published under licence by IOP Publishing Ltd.
