Abstract

Cibodas Botanical Garden (CBG) maintains not only native plant species but also introduced plant species. Some of these have been naturalized from CBG to the adjacent Mt. Gede-Pangrango National Park (GPNP). One of the reported naturalized species is Bartlettina sordida. Understanding species traits will give information for the future management of B. sordida. This research investigates the distribution of B. sordida in the Cibodas hiking trail and studies leaf traits variation of this species along with an altitudinal change in the Cibodas hiking trail. Samples were collected along the Cibodas hiking trail from the entrance gate to the Cibeureum waterfall. At every survey location, we recorded B. sordida occurrences. In the sample plots we also collected leaf samples from detected B. sordida. The leaves were then fixated using the hands-free method to observed stomatal type, density, and size. The leaves were also treated for specific leaf area (SLA) measurements. Stomata size is significantly correlated along the altitudinal gradient. Stomata density is negatively correlated but not significant along the altitudinal gradient. Stomata size is positively correlated with SLA. These traits are related to water-efficient adapting to GPNP climate, which is very different from its natural habitat. The ability to adapt to altitudinal gradient helps B. sordida to dominate the Cibodas hiking trail.

Abstract

Penyebaran Cestrum aurantiacum Lindl. di hutan remnant sekundair Wornojiwo Kebun Raya Cibodas (KRC) dianalisis dalam penelitian ini menggunakan Nearest Neighbor Method. Peranan (korelasi) faktor lingkungan terhadap pola penyebaran C. aurantiacum dibandingkan dengan jenis pohon asli dan dilakukan dengan menggunakan cluster analysis. Faktor-faktor lingkungan yang digunakan dalam cluster analysis ini yaitu: intensitas cahaya, keasaman tanah, kelembapan tanah dan kelembapan udara. Hasil analisis penyebaran menunjukkan bahwa jarak penyebaran C. aurantiacum hampir lima kali lebih besar daripada penyebaran yang diasumsikan terjadi secara acak. Hasil cluster analysis menunjukkan bahwa intensitas cahaya berhubungan secara nyata dengan penyebaran C. aurantiacum di hutan Wornojiwo. Intensitas cahaya rata-rata di plot dengan C. aurantiacum lebih besar dibandingkan dengan plot tanpa C. aurantiacum. Contoh pengaplikasian hasil penelitian ini adalah memprioritaskan eradikasi C. aurantiacum yang ada di pinggir hutan daripada yang ada di bagian tengah. Hasil penelitian ini juga mempertegas pentingnya memelihara tegakan hutan alami untuk memelihara naungan hutan.

Abstract

Cibodas Botanical Garden (CBG) is an ex-situ plant conservation institution, maintaining living collection from various taxa including Rubiaceae. Most of Rubiaceae ornamental plants are introduced species with regard to their attractive characters. However, introduced species of ornamental plants is one of significant global plant invasion pathways. The aims of this research was to conduct inventory study of CBG’s Rubiaceae collection, to determine native and introduced species, and to bring out CBG’s native Rubiaceae potential as ornamental plants. The research was divided into two methods, field study and literature study. Field study was conducted by making inventory of Rubiaceae living collections and plant morphology observations. Literature study was conducted by obtaining data of plant distributions, utilization as ornamental plants, and also comparing domesticated species with CBG’s living collections. Results showed that CBG has collected 20 genera, 50 species and 116 specimens of Rubiaceae as living collections. There are 22 native species, 15 introduced species and 13 species that can not be determined. There are 5 species commonly utilized and cultivated as ornamental plants, 8 species are not known for their aesthetic characters but has potential as ornamental plants. These species are Gardenia pterocalyx Valeton, Hypobathrum frutescens Blume, H. racemosum (Roxb.) Kurz, Mycetia cauliflora Reinw., Pavetta montana Reinw. Ex Blume, Psychotria angulata Korth, P. montana Blume, and Wendlandia densiflora (Blume) DC. This study demonstrated that there is a promising potential from these lesser-known native Rubiaceae species for ornamental use. CBG should conduct more research about native species’s potential as ornamental plants.

Abstract

The study of exotic epiphytes on tree ferns is relatively scarce. Biological invasion of exotic epiphytes may imply negative consequences to native epiphytes and tree ferns, which are important components in tropical mountainous rainforest ecosystems. This study surveyed exotic epiphytes on tree ferns in Cibodas Botanical Gardens (CBG) and adjacent forests next to CBG. The objectives of this study are: a) to conduct inventory study of exotic epiphyte species on tree ferns, b) to examine how different these exotic epiphytes from each other based on their micro-climate preferences, c) to conduct invasive risk assessment of those exotic epiphytes, and d) to model the effect of environmental factors and host (tree ferns) characteristics to the occurrence of exotic epiphytes on tree ferns. We conducted multi-dimensional analysis to examine how different these exotic epiphytes based on their micro-climate parameters. We used Weed Risk Assessment (WRA) framework to estimate the invasion risks of surveyed exotic epiphytes. We performed Bayesian logistic regression to test the correlation between environmental and host characteristics and the occurrence probability of exotics epiphytes on tree ferns. We found 13 exotic epiphyte species on two native tree ferns species (Cyathea junghuhniana and Cyathea contaminans). Multidimensional analysis showed that Axonopus compressus is very different from other exotic epiphytes due to its environmental preferences. Ageratina riparia and Clidemia hirta were exotic epiphytes with the highest invasion risks. Therefore, we suggested that A. riparia and C. hirta are more likely to become invasive and may contribute significant impacts to native ecosystems. Lastly, the presence of Austroeupatorium inulaefolium as exotic epiphytes in tree ferns negatively correlated with the host height. Further study is needed to incorporate biological traits of the exotic epiphytes and more specific environmental parameters such as light chromatic quality in to the exotic epiphyte occurrence model. This study provides evidence for the existences of exotic epiphytes on tree ferns. The result of this study may also indicate that host characteristics and micro-climate factors could play important roles to inhibit the occurrence of exotic epiphytes on tree ferns.

Abstract

BBotanic Gardens cultivates exotic species for the purpose of ornamental plants. Moreover, these exotic species have the probability to escape the garden area and naturalized in adjacent forests. Cibodas Botanical Garden (CBG) is adjacent to four remnant forests: Jalan akar, Bengkel, Lumut, and Wornojiwo forests. There are several reports of naturalized CBG collections in Wornojiwo, thus this study does the inventory of naturalized exotic CBG collections in Cibodas remnant forests and perform Tropical Weed Risk Assessment Protocol (TWRAP) of these species. We found 26 CBG exotic species naturalized in remnant forests and more naturalized exotic species in Lumut and Jalan Akar forests than Wornojiwo and Bengkel forests. We presumed the topographic condition in Bengkel forest inhibit the spread of exotic species, meanwhile Jalan akar forest was located in the center area of CBG therefore holds the greatest number of naturalized exotic species. We found the domination of Chimonobambusa qudrangularis in Wornojiwo forest inhibiting other exotic species growth. The largest figure of the naturalized species belong to the family of Asteraceae, followed by Solanaceae, Marantaceae, Fabaceae, and Acanthaceae. The TWRAP assessment score results of the 81% naturalized species were above 10. Therefore TWRAP can be used as an early screening for botanic gardens exotic species naturalization probability. CBG commits to support the post-2020 biodiversity CBD target, with this inventory CBG can monitor the spread of CBG exotic plant collections that threaten native plant diversity and prevent future spreading of other exotic species.

Abstract

Cibodas Biosphere Reserve, with Gunung Gede Pangrango National Park as the core zone area, has an enormous number of naturalized alien species spread within it. There are 88 alien plant species, and more than 50% are utilized for many purposes. This research documented the utilization of these naturalized alien plant species, particularly for traditional medicine. Data were obtained by interviewing 90 respondents in three locations around Cibodas Biosphere Reserve using questionnaire sheets. The questionnaire used the Index Cultural Significance framework to quantify the value of every species for traditional medicine. The results showed that the community used 41 naturalized alien plant species from 15 families. Asteraceae is the family with the most widely used species and has various medicinal benefits. The most frequently treated health problems are anti-inflammatory, dental and oral health, and fever. ICS value showed that the utilization rate is low, yet these plants have promising properties as sources of natural medicine. Moreover, the utilization of these alien plants can be an option in controlling these species to prevent the invasion of Gunung Gede Pangrango National Park.

Abstract

Preventative management, such as framework-based assessment, considered as the best option for invasive species management. Alternatively, risk assessment can be conducted based on traits of occurred invasive species to build prediction system for invasive risk assessment. This study aimed to test whether trait-based assessment system can differentiate the escaped from non-escaped exotic collections of botanic gardens and to compare the reliability of trait-based versus framework-based risk assessment on differentiating these escaped from non-escaped exotics. In this study, Bayesian logistic regression analysis was conducted to assess the reliability of framework-based and trait-based risk assessment systems. For trait-based system, clear effect of leaf trait, height, and dispersal method to escape probability was detected. For framework-based system, clear effect of Tropical Weed Risk Assessment Protocol on escape probability was detected. Leaf trait, dispersal method and height are reliable predictors for escaped probability of botanic gardens exotic collection. The fact that the reliability of trait-based assessment systems is better than the commonly used framework-based system is the main novel finding in this study. This finding implies that trait-based is better than framework-based for invasive species risk assessment approach in Indonesian botanic gardens. Trait-based assessment also a relevant tool to support management with limited resources to conduct adequate early risk assessment.

Abstract

Miconia crenata is a widely spread species that occurs in multiple ecosystems. However, there is limited information on M. crenata invasion biology, ecology, and anatomy, particularly in the context of mountainous tropical forest and biodiversity management. Therefore, we examined elevation effects upon leaf anatomical structure of exotic invasive M. crenata at Mount Gede-Pangrango National Park (MGPNP). We sampled the leaves at four different elevations i.e., 715 m asl, 800 m asl, 900 m asl, and 1,000 m asl. Cross section leaf anatomy specimens of M. crenata were obtained by using paraffin method and stained with safranin and fast green. This study found that M. crenata leaf anatomy was correlated with elevation shown by changes in leaf tissue thickness and stomata size. Further study is needed of leaf anatomical variation of exotic invasive species along driven by soil properties and the variation across different plant taxa and growth forms. Such studies are important to determine adaptation capacity of invasiveness.

Abstract

Andaliman (Zanthoxylum acanthopodium) is a specialty spice widely found in the Provinces of North Sumatra and Aceh, Indonesia. The fruit is usually used by Batak people in North Sumatra as a food ingredient to cook Batak’s cuisine such as arsik, tombur, and naniura. It is also used as one of the ingredients to make Indonesian spicy sauce called sambal. Andaliman fruit is reported to eliminate the undesirable smell in fish and raw meat. Moreover, it could also reduce total volatile base nitrogen content in fish which helps to prevent spoilage. Furthermore, andaliman has been reported to contain bioactive compounds which act as antioxidant, antimicrobial, anti-inflammatory, anti-aging, anti-acne, and anti-halitosis effects. This review focuses on the botanical aspects of and health potential exhibited by andaliman.
