Abstract

Vegetations in post-agriculture forests (PAF) have the potential to absorb carbon dioxide and store it in to the form of biomass. However, information on carbon stocks in post-agriculture secondary forest in Papua, Indonesia still needs to be available. This study aimed to analyze the density of vegetation and its relationship to the carbon stock of aboveground vegetation biomass on PAF in the lowland of Manokwari, West Papua. This study was conducted on PAF aged 4 and 7 years using a one-factor, completely randomized design. Carbon stock is calculated using an allometric equation based on a diameter at breast height of 1.30 m (dbh ≥5cm). The results showed that 60% of the relative density of trees on the two PAF’s was composed by Premna odorata, Piper aduncum, and Macaranga tanarius. Carbon stocks on PAF aged 4 and 7 years reach 550 kg/ha and 140 kg/ha respectively. There is an increase in aboveground biomass and carbon stock with relative tree density and, tree diameter, which is significantly affected by the age of the PAF (P<0,002). The low carbon stock on PAF aged four years indicates that there has been a significant decrease in soil fertility after several years of cultivation by the local Papuan community. Therefore, there must be a difference in land use management between natural secondary forest and post-agriculture forest.

Abstract

Water availability in Mount Ciremai National Parks (MCNP) is influenced by sustainability of the vegetation. Therefore, tree regeneration around the water springs area needs to be investigated to maintain the sustainability of water springs ecosystem in the future. The purpose of this study was to analyzed and identify natural seedlings of tree regeneration around the water springs area Seda Block MCNP. The collections of vegetation and abiotic data was carried out on 9 sample plots measuring 3 m × 3 m which is purposively placed around water springs. Result show that vegetation in water springs dominate by seedlings Ficus sp., Ficus hemsleyana, and Trevesia sundaica. Shannon-Weiner diversity index in this location was moderate, but evenness and dominance index classified as high and low, respectively. Overall, seedling of trees dominated by orthodox seed-type and shade tolerant plant. The vegetation in this study dominated by plants categorized least concern (LC) based on IUCN red list. Microclimatic of study site affects 58.89% on abundance and distribution of tree seedlings. Therefore, the springs are in the Seda Block MCNP needs to be conserved and maintain its natural vegetation.

Abstract

Exploration studies of ferns in Papua Indonesia are still limited, while habitat pressure is increasing due to massive development. The purpose of this study was to quickly explore potential habitats of ferns in several areas in Manokwari Regency, West Papua Province. Direct observation methods and fern collections were carried out without observation plots. The ferns collected were unique and rare ferns. Samples from the collection were then carefully observed and made into sketches to facilitate the description process. Taking research location points and measuring environmental parameters were also carried out in areas where ferns were found. The results of the study showed that there was a diversity of habitat types, environmental conditions and how ferns grew. 10 types of ferns were found from four observation locations. The ten ferns were Psilotum nudum, Psilotum complanatum, Microsorum diversifolium, Nephrolepis biserrata, Blechnum orientale, Lycopodium cernuum, Lycopodium phlegmaria, Selaginella wildenowii, Stenochlaena palustris, and Lygodium microphyllum. Rare species tend to be less abundant, while cosmopolitan and potentially invasive species are very abundant. Literature studies show that more than 80% of the fern species that have been successfully inventoried have the potential to be medicinal plants. Based on the results of this initial study, quantitative ecological studies and bioprospection of ferns in Manokwari, West Papua still need to be carried out as an effort to conserve ferns Keywords: habitat exploration; Psilotum; Lycopodium; fern bioprospecting

Abstract

Using synthetic pesticides has polluted the environment, so efforts are needed to find alternative natural pesticides from plants. This study examines plant species with potential as botanical pesticides in Bowi Subur Village, Masni District, Manokwari Regency. The research method used is descriptive, with a sampling technique combining plot line transects, and it was conducted along 13 transects corresponding to the housing areas in Bowi Subur Village. The plants were documented, and relevant literature was reviewed. The inventory results identified 46 plant species from 25 families with pesticidal properties. Of these, 35 species are used for pest control, seven for disease management, and one for weed control. Additionally, three plant species were found to be effective for both pest and disease control. Most parts used for pesticide purposes are leaves, accounting for 19 plant species. We conclude that most species of plants used as natural pesticides are cultivated plants. Therefore, wild plants with potential for botanical pesticides are essential for further study their properties.

Abstract

Pressure on coastal water conditions in Manokwari caused by human activities can affect the morphometric adaptation of seagrass plants, one of which is Halophila ovalis. The study aimed to analyze the morphometric differences of Halophila ovalis caused by differences in environmental factors on several coastal areas in Manokwari. A total of 20 samples of H. ovalis were taken from each of the beaches studied and then four morphological characters were measured. Morphometric data of H. ovalis between locations were analyzed using analysis of variance (ANOVA), then continued with non-multidimensional scaling (NMDS) analysis. The results showed that there were changes in the morphometrics of H. ovalis from the four research locations. Specifically, it was found that the H. ovalis with the most different morphology came from Rendani Beach. NMDS analysis shows that the morphometrics of H. ovalis on Rendani Beach are separate from  from Yenkarwar, Wosi and Saubeba Beaches. The NMDS model was explain 74.19% of the morphometric diversity influenced by environmental parameters such as water temperature, substrate conditions, pH, salinity, and dissolved oxygen levels. We concluded that there had been morphometric changes in the seagrass H. ovalis in several coastal waters in Manokwari.

Abstract

This study aimed to explore the use of plants as traditional medicine by indigenous Papuans in the Arfak Mountains. The local population residing in the villages of the Arfak Mountains primarily consists of the Arfak tribes, including the Hatam, Sough, and Meyah. These communities have traditionally relied on local plants to address various health issues. The research employed a descriptive method, incorporating interviews and direct field surveys. Respondents were selected based on their extensive knowledge of medicinal plant use. The results revealed that 20 plant species are utilized by the local population to treat a range of health conditions. These include coughs, colds, fevers, flatulence, itching, boils, malaria, external wounds, hypertension, body aches, internal pain, lumps, fertility issues, facilitation of childbirth, and ailments attributed to witchcraft. Some plants are used individually, while others are combined with different plants. Processing methods include mashing, boiling, or squeezing to extract the liquid. Utilization methods involve drinking, chewing and swallowing the juice, or applying it to affected areas. The plant parts used include leaves, stems, tubers, and flowers.

Abstract

Knowledge of competition at the plant community level is useful as a basis for studying competition aspects in a broader scope. One of the simplest things is understory competition due to differences in tree canopy cover. The purpose of this study was to describe the role of shade trees on competition and understory community structure. A total of 6 plots measuring 1 m × 1 m were made under stands of Ficus calosa, Ficus benjamina, and Terminalia catappa trees (Location 1 and Location 2), while 3 other plots of the same size were made under stands of Hevea brasiliensis trees (Location 3). Structure, composition and diversity were studied using vegetation analysis techniques. The results showed that Locations 1 and 2 were dominated by Phytolacca americana and Asystasia gangetica, while Location 3 was dominated by Axonopus compressus and Asystasia gangetica. Further analysis showed outlier data from the three locations indicated an abundant number of individuals of Phytolacca americana and Asystasia gangetica, and Axonopus compressus. All of these dominant species are invasive. Regression analysis shows that the projection of increasing canopy cover causes an increase in the density of certain species, but not significantly (P >0.05). The higher the dominance index, the smaller the species diversity value. Therefore, it can be concluded that a dominant species is usually competitive and can change the distribution structure and diversity of understory plants under different tree canopies.

Abstract

The shifting cultivation system is an integral part of the local culture of the Papuan people in Indonesia, persisting to this day. This study investigates the relationship between vegetation abundance and soil chemical composition in former plantation lands of varying ages in Papua, Indonesia. Three sites with distinct fallow periods - 5 years (BK-5), 10 years (BK-10), and 15 years (BK-15) - were analyzed. Multivariate analysis was employed to model the combination of dominant vegetation density and soil physical and chemical characteristics. The results revealed that the BK-5 site exhibited poor soil quality, characterized by acidic pH and low organic carbon and nitrogen content. In contrast, the BK-10 and BK-15 sites demonstrated improved soil fertility. The multivariate analysis highlighted distinct differences in vegetation composition and soil nutrient parameters among the sites, with specific plant species associated with particular soil conditions. The study confirms that older former plantation lands tend to have higher soil fertility, suggesting that short fallow periods may be insufficient for optimal soil fertility restoration. These findings underscore the importance of considering the age of former plantation lands and the role of vegetation in shaping soil conditions. This research provides valuable insights into the ecological recovery of post-agricultural landscapes in Papua.
