Invasive alien / exotic species (IAS) are one of the major global threat that contributing to plant extinctions. Interestingly, there are also many exotic species that are threatened with extinction that are housed in Botanical Gardes throughout the world. We defined threatened species as plant species with Red List IUCN category of VU (vulnerable)...
Botanic Gardens cultivatesexotic species for the purpose of ornamental plants. Moreover, theseexotic 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 naturaliz...
Participants in scientific conferences have been traveling to the cities of conference venues. These mobilizations left carbon footprints due to carbon dioxide (CO2) emissions generated from the scientists' transportation to their conference venue. This study looks at the carbon footprint of scientists who attended scientific biodiversity conferenc...
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 o...
Castanopsis argentea (Blume) A.DC., commonly known as saninten, is an endangered evergreen tree species native to Sumatra and Java Islands, Indonesia. This study was carried out to assess the genetic diversity of C. argentea in Mount Gede Pangrango National Park (MGPNP) based on random amplified polymorphic DNA markers.

More than 80 potentially invasive plant species have spread throughout the Cibodas Biosphere Reserve, Indonesia. Recently, research has shown that the surrounding community utilizes more than 50% of these species. Although this utilization provides social and economic benefits, it threatens the Cibodas Biosphere Reserve core zone ecologically. Ther...
Exotic plant invasion is one of the major causes of species extinction. In many contexts, mountainous forests are the last refuge for native species. There are several inventory studies conducted in mountainous and tropical forests in Indonesia. However, there are no studies yet on the factors that explain the abundance and richness of surveyed nat...
A primary objective of botanical gardens is to conserve threatened plant species from different regions and countries. However, such ex-situ conservation practices for exotic plant species may pose a significant plant invasion risks. In this study, we predict the naturalization probability of exotic threatened plant species of Cibodas Botanical Gar...

Assessing the utilization of naturalized alien plant species by community to inform its management strategy: A case study in Cibodas Biosphere Reserve, West Java, Indonesia. Biodiversitas 22: 2579-2588. Alien plant species can have two side effects, either positively in terms of the utilization of these spe...
The plant collections in a botanic garden were not only gathered from the native country, but also were introduced and sometimes carried invasiveness traits. Therefore, Indonesian botanic gardens, including Cibodas Botanic Gardens (CBG), need to carry out risk assessment of invasiveness based on plant traits. This research aims to analyze the consi...
1. The establishment of new botanic gardens in tropical regions highlights a need for weed risk assessment tools suitable for tropical ecosystems. The relevance of plant traits for invasion into tropical rainforests has not been well studied.
2. Working in and around four botanic gardens in Indonesia where 590 alien species have been planted, we es...

It is also used as one of the ingredients to make Indonesian spicy sauce called sam...
Dipterocarpaceae are globally important tree family due to its conservation status.
Most of Dipterocarpaceae in Java are distributed in lowland area. However, several species
exist in higher altitude such as Gede Pangrango National Park (GPNP) area. All
Dipterocarpaceae species in GPNP are vulnerable or endangered based on IUCN Red List
status. Dip...
Knowledge of community structures and capacity to differentiate invasive from non-invasive species are essential for invasive species management. Specific Leaf Area (SLA) is a potential proxy to differentiate invasive from non-invasive species. This study aims to identify the relationship between Important Value Index (IVI) with SLA of Asteraceae s...
Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research sp...
CBG’s plant collection managed and displayed in the garden based on the taxonomic classification system and thematic system. Plant collection that managed as a thematic system displayed and managed as a thematic garden. The aim of this study is to conduct an inventory study of CBG medicinal thematic garden collections and to do a literature study a...
Knowledge of community structures is one of the essential preventive efforts towards spread of invasive species that important to do. This study aims to describe the community structure of Asteraceae family based on shade characteristics at Cibodas Botanical Garden. The community structure data were obtained by measuring the extent of leaf cover an...
Andaliman ((Zanthoxyllum acanthopodium DC.) is well-known as unique Bataknese culinary herb in North Sumatra. In Indonesia, this species only naturally occurs in the northern part of Sumatra, that are Aceh and North Sumatra. Andaliman is an important species from economic, cultural, and conservation perspectives, particularly for North Tapanuli are...

Andaliman (Zanthoxylum acanthopodium) is an important species in North Sumatra, Indonesia either from conservation, economy, or socio-cultural point of views. Z. acanthopodium is known as plant species diffi...
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 different...
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...
Detecting exotic plant species is essential for invasive species management. By accounting for factors likely to affect species’ detection rates (e.g. survey conditions, observer experience), detectability models can help choose search methods and allocate search effort. Integrating information on species’ traits can refine detectability models, an...

Line transect distance sampling lay out.
Black circles represent individuals of exotic species and dashed arrows show their perpendicular distance to the transect. Surveys were conducted from the border of the botanic gardens towards the native rainforest interior. Only detections within 10 m of the transect line were recorded. The number of transe...

Quantitative analysis on exotic invasive species decision making in Indonesian botanic gardens (Cibodas Botanic Gardens)
Botanical gardens are considered as part of tropical invasion pathway. The extent of management effort to
minimise plant invasion may be determined by the attitude of people managing botanical gardens. Social
aspect may become a hindrance for invasive species management because people may like invasive species for
certain reasons. Thus, there is a...
