Diversity of types pterodhopita in the campus Universitas Sumatera Utara

Abstract

Forests in Indonesia that have high biodiversity, including one of them is the type of fern. The characteristic of Indonesian tropical rainforests is that they have high rainfall so that they strongly support the existence of this type of fern. In general, ferns like humid habitat conditions. The purpose of this study was to determine the types of ferns around the campus Sumatera Utara. The method of this research is by roaming, namely exploring each location that can represent the location where there is the most vegetation. The number of types of ferns found on the campus of the Universitas Sumatera Utara is 20 types. There are 9 families in the research location, including the polypodiaceae family as much as 35%, Pteridaceae (20%), Thelypteridaceae (15%), Nephrolepidaceae (10%), Aspleniaceae (10%), Athyriaceae (5%), Dryopteridaceae (5 %) and Blechnaceae (5%). There are 13 types that grow epiphytic and 7 that live terrestrially. The host trees for epiphytic ferns include Swietenia mahagoni, Elaeis guineensis, Gmelina arborea, Samanea saman and Paraserianthes falcataria.

Species diversity, richness, and conservation status of Pteridophyta in the karst ecosystem of Donorejo Forest, Kaligesing, Purworejo, Indonesia

“…In comparison, the types of Pteridophyta that live in lithophytes or rock crevices are A. capillus-veneris and C. interruptus, which are also found to live terrestrially while the rest live terrestrially. Rambey et al (2021) state that Pteridophytes with terrestrial habitats are more commonly found in karst areas than in urban areas. The existence of epiphytic Pteridophytes ecologically acts as a habitat for several types of insects.…”
