Abstract

Mount Merbabu National Park is a conservation area with a high diversity of unique flora and fauna. The purpose of this study was an inventory of Plantae Divisio of Pteridophyta in Mount Merbabu National Park, Selo, Boyolali Regency. The method used wes exploration with a zoning system, namely the utilization zone and the core zone. The results were analyzed descriptively on characteristics, habitus, benefits, and distribution. Based on the results of the study, it was found that the diversity of Pteridophyta was 41 species in 2 classes and 14 families. Pteridophyta in 2 classes, namely Lycopodiinae and Filicinae. The species included in the Lycopodiinae were Class are Lycopodium clavatum and Huperzia squarrosa. Other species belong to the Class Filicinae.

The benefits of Pteridophyta include ornamental plants, growing media, various kinds of traditional medicine, and a mixture of organic fertilizers. The spread of Pteridophyta is in a place where the higher it is, the Pteridophyta is, the less the number of Pteridophyta is. Pteridophyta in Sabana with an altitude of 2,571 masl, there was only one species, namely Pteridium aquillinum.
