“…Pola sebaran spasial vegetasi yang mengelompok juga berkaitan dengan kondisi habitat yang digambarkan melalui nilai keanekaragaman jenis, dimana semakin tinggi nilai keanekaragaman jenis maka akan semakin tinggi tingkat kestabilan ekosistem (Putra et al, 2019). Hal itu membuat keanekaragaman spesies menjadi tinggi karena didorong oleh proses regenerasi serta suksesi yang tinggi pada habitat yang sesuai (Muis & Arianingsih, 2022;Zhao et al, 2023). Selain itu, terjadinya pola sebaran spasial yang mengelompok memperlihatkan kecenderungan berkumpulnya vegetasi pada habitat yang menguntungkan bagi tumbuhan tersebut.…”

Medicinal plants are included in the Non-Timber Forest Products group, which has a variety of benefits, especially for human life and high economic value. Its existence is abundant in one of the customary forests in Riau Province, Ghimbo Pomuan Customary Forest. For the preservation and planning of medicinal plant management activities, it is necessary to analyze the spatial distribution of medicinal plants and determine the relationship between accessibility factors and the presence of medicinal plants. This research aims to analyzed the spatial distribution pattern of medicinal plants, map the distribution of medicinal plants, and determine the factors that affect spatial distribution based on accessibility factors. This research was conducted between March and November 2023. This study found that Ghimbo Pomuan customary forest has 24 species of plants with a total of 324 medicinal plants.The seven medicinal plants with the highest number are kacip fatimah (Labisia pothoina) 106 individuals, mempening (Lithocarpus spp) 50 individuals, matoa (Pometia pinnata) 34 individuals, pasak bumi (Eurycoma longifolia) 32 individuals, binahong (Andredera cordifolia) 30 individuals, keladi tikus (Typhonium flagelliforme) 19 individuals and bintangur (Clophyllum soulatri) 9 individuals. The spatial distribution pattern of medicinal plants is clustered with the nearest neighbor index NNI 0.58. The most influencing factor is the distance from the river, which is then followed by the distance from the road and the distance from the settlement. The farther from the river, the number of medicinal plants tends to increase, the closer the distance from roads and settlements, the number of medicinal plants increases.

“…Seeds of aquatic plants are necessary for the restoration of the declined population, and re-seeding is an effective method to restore the disappeared vegetation [3]. Furthermore, regeneration from seeds is important for the diversity and composition of plant communities [4]. Consequently, understanding of seed storage methods and germination requirements is very important to conserve them successfully and to restore vegetation.…”

Understanding of seed germination requirements and storage methods is very important to successfully conserve and restore aquatic vegetation. The main question addressed by the research was germination requirements and suitable seed storage methods of Hydrocharis dubia seeds. Furthermore, the water content and respiration rate of H. dubia seeds were studied under different storage conditions. The study found that light and high seed clustering density had a positive effect on germination, while burial had a negative effect. Germination percentages were 60.67 ± 6.11% and 28.40 ± 6.79% in light and dark conditions, respectively. Under clustering densities of 1 and 50, germination percentages were 6.00 ± 2.00% and 59.33 ± 0.67%, respectively. Germination percentages were 50.40 ± 5.00%, 3.20 ± 3.20%, and 0.80 ± 0.80% at depths of 0, 2, and 3 cm, respectively. Oxygen, water level, and substratum had no significant effect on seed germination. Storage method had a significant effect on seed germination, moisture content, and respiration rate. The germination percentages were 64.00 ± 1.67%, 85.20 ± 5.04%, and 92.80 ± 4.27% under the storage conditions of 4 °C-Dry, 4 °C-Wet, and Ambient water temperature-Wet for 2 years, respectively. The seeds had no germination under the storage conditions of Ambient air temperature-Wet and Ambient air temperature-Dry. Overall, the study indicates that seed germination of H. dubia is restricted by light, burial depth, and seed clustering density. Additionally, it was found that H. dubia seeds can be stored in wet environmental conditions at ambient water temperature, similar to seed banks. Specifically, the seeds can be stored in sand and submerged underwater at ambient water temperatures ranging from 4 °C to 25 °C. This study will help with the conservation and restoration of aquatic plants, such as H. dubia.
