Abstract

Mangrove vegetation generally grows to form a zoning starting from a beach to a view of meters inland. Mangrove zoning consists of Avicennia plant species that face directly toward the sea and behind or on the edge of the Avicennia plant. There is the Riophora plant. Towards the mainland, there are Bruguiera plants and, finally, the Ceriops plant which grows and interacts with small bushes. Each type of Mangrove plant has a level; the first is the seedling level, the second is the sapling level, the third is the pole level, and the fourth is the tree level. This study aims to analyze the Mangrove Vegetation Community in Bunaken Nation Park, Teling Village, using a descriptive survey method and constructing three transects, which are transected measuring 10×10 m2, 5×5 m2, and 2×2 m2. The result on each transect shows that in Bunaken National Park, Teling Village, there were types of Mangrove Vegetation Communities, namely Avicennia plant species with a total of 129, Rhizophora plant species with a capacity of 122 and Bruguiera plant species with a total of 91, where each plant type it has levels with different numbers.

Abstract

Ferns (Pteridophyta) are spore-forming cormophytes that can live in a variety of habitats both as epiphytes, terrestrial and aquatic. In the forest area of Noongan Village, many potentials play an important role in developing forest ecosystems. One such potential is ferns. The results of the study were eight types of ferns in the forest area of Noongan village which were divided into two plots of 50x50 meters at different heights, namely plot I at an altitude of 610 masl with a total of 380 ferns with the percentage: Paku Garuda (Pteridium aquilinium) 0.20 %, Elephant fern (Angiopetris avecta Hoofm) 0.01%, Red rane fern (Selaginella australis) 0.01%, Paku Kikir (Stenosomia Sp.) 0.14%, Ferret fern (Nephrolepis biserrataSchott.) 0, 21%, cecerenean fern (Nephrolepis falcata) 0.16%, suplir fern (Adiantum.) 0.12%, andam fern (Dicranopetris linearis) 0.12%. And plot II at an altitude of 869 meters above sea level with a total of 179 ferns with a percentage of: Garuda fern (Pteridium aquilinium) 0.21%, elephant fern (Angiopetris avectaHoofm) 0.01%, miserly fern (Stenosomia Sp.) 0, 17%, Paku harupat (Nephrolepis biserrate Schott.) 0.21%, Paku cecerenean (Nephrolepis falcata) 0.15%, Suplir (Adiantum.) 0.10%, Paku andam (Dicranopetris linearis) 0.12%. In the plot I, the types and number of ferns were higher than the types and numbers of ferns in plot II. No red fern (Selaginella australis) was found in plot II. And the plant species Paku Harupat (Nephrolepis biserrata Schott). The red fern has the highest number, and the red fern (Selaginella australis.) has the least amount. The difference in altitude greatly affects the surrounding environment. So that these differences greatly affect the number of types and numbers of ferns
