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

Abstract

Riparian vegetation plays a crucial role in maintaining aquatic ecosystem stability by acting as a natural buffer against anthropogenic pollution and erosion. This study analyzed the composition, structure, and ecological functions of riparian vegetation in Lake Tondano, North Sulawesi, Indonesia, with emphasis on pollutant filtration and sediment stabilization. Field surveys were conducted from May to August 2025 at ten riparian stations surrounding Lake Tondano (4,638 ha). Vegetation sampling used a stratified line transect method with fifty plots of varying sizes according to vegetation strata. Quantitative analysis included relative abundance, frequency, dominance, Importance Value Index (IVI), and the Shannon–Wiener diversity index (H’). Ecological functions were assessed through correlations between vegetation structure and reported nutrient and sediment reduction efficiencies from tropical riparian studies. A total of fifteen dominant riparian species were identified, mainly from the families Poaceae and Cyperaceae. Cyperus papyrus (IVI = 21.81%) and Metroxylon sagu (IVI = 29.65%) functioned as key ecological species, while Ficus septica showed the highest IVI (90.83%), indicating strong structural dominance. The Shannon–Wiener diversity index (H’ = 2.65) reflects moderate to high diversity. Riparian vegetation was estimated to reduce nutrient loads by 40–60% and erosion by 30–50%, highlighting its importance for ecosystem-based lake management.
