Yuzammi. 2018. The diversity of aroids (Araceae) in Bogor Botanic Gardens, Indonesia: Collection, conservation and utilization. Biodiversitas 19: 140-152. Bogor Botanic Gardens is an ex-situ conservation centre, covering an area of 87 ha, with 12,376 plant specimens, collected from Indonesia and other tropical countries throughout the world. One of the richest collections in the Gardens comprises members of the aroid family (Araceae). The aroids are planted in several garden beds as well as in the nursery. They have been collected from the time of the Dutch era until now. These collections were obtained from botanical explorations throughout the forests of Indonesia and through seed exchange with botanic gardens around the world. Several of the Bogor aroid collections represent ‘living types’, such as Scindapsus splendidus Alderw., Scindapsus mamilliferus Alderw. and Epipremnum falcifolium Engl. These have survived in the garden from the time of their collection up until the present day. There are many aroid collections in the Gardens that have potentialities not widely recognised. The aim of this study is to reveal the diversity of aroids species in the Bogor Botanic Gardens, their scientific value, their conservation status, and their potential as ornamental plants, medicinal plants and food. The methods of the research include direct observation in the garden and nursery collections, analysis of the Gardens’ long-term registration database, as well as herbarium studies in both the Herbarium Bogoriense and the Gardens’own herbarium. A total of 130 species of aroids belonging to 36 genera have been cultivated in the Bogor Botanic Gardens. It is estimated that the gardens has 29% of the total number of genera in the world (21 genera are native to Indonesia). The aroid collection consists of terrestrial plants, aquatic plants and climbing plants (61 species, 12 species and 57 species, respectively). Amorphophallus paeoniifolius has developed further as a food plant. Genera such as Aglaonema, Alocasia, Apoballis, Rhaphidophora and Scindapsus have long been used as ornamental plants. Futhermore, some Homalomena species can be extracted for essential oils, while Epipremnum pinnatum has application in the treatment of cancer. Descriptions of some endemic, rare and high value species are discussed in this paper.

Amborella trichopoda Baill., the most ancestral angiosperm, has been successfully cultivated in the Botanic Gardens of the University of Bonn in Germany (BG Bonn) for more than a decade. The distribution of this plant – limited to the South Pacific island of New Caledonia – and its cultivation has so far only been achieved in a few botanic gardens. This paper provides details about the cultivation and propagation of Amborella, and information on its cultivation in botanic gardens around the world. The authors propose that the collections of this plant in botanic gardens could be used to establish ex situ conservation collections.

Study Case

Delphinium fissum subsp. sordidum is a restricted endemic subspecies whose core distribution is located in the central-western Iberian Peninsula with a disjunct subpopulation in Sierra Mágina (Jaén Province). This article reports a detailed study of its current distribution, population size and structure, and the threats that it faces. Phytosociological analysis shows two main plant communities where D. fissum subsp. sordidum develops: Quercion pyrenaicae and Quercion broteroi. According to the most recent IUCN categories and criteria, the conservation status of D. fissum subsp. sordidum is “Endangered” (EN) in Castile and Leon. We propose the creation of a Plant Micro-Reserve (PMR) in an enclave with high geological, ecological and conservation values. Medium-long term and individualized monitoring programs are required for all distribution range of Delphinium fissum subsp. sordidum. An overall Recovery Plan for the subspecies should be considered and implemented, including in-situ and ex-situ conservation measures that guarantee its protection, conservation and recovery.

The Acharya Jagadish Chandra Bose Indian Botanic Garden (AJCBIBG) previously known as Indian Botanic Garden, Howrah, is a historic old garden. This botanic garden has a special position among all the botanic gardens that the world having. In earlier time this garden witnessed as the centre of plant introduction. Till then AJCBIBG served as a centre for ex-situ conservation of many RET species collected from different parts of the globe. The rich and diverse floristic wealth of this garden makes it unique and very special. AJCBIBG is a living repository of 1377 species of plants (excluding herbs). The garden abode a rich herbaceous flora due to its congenial climate. However, records on the herbaceous plants dwelling in AJCBIBG are very scanty. Taking this into account the present study aimed at enlisting the herbaceous flora of the garden. A checklist of plants belonging to various families has been provided in this communication.

Nepenthes Khasiana

Ex-situ conservation is an important key in the management of rare, endangered and threatened (RET) plant species and its effectiveness depends on several factors. Maintenance of viable germplasm and its subsequent propagation plays an important role in long term conservation of many RET species. Nepenthes khasiana is a rare and gravely threatened species in the wild due to over-collection and other threats. The species needs urgent in-situ and ex-situ conservation. Development of easy to propagate techniques would pave faster multiplication for its use of educational, medicinal and horticultural purpose. In the present paper, successful propagation technique of Nepenthes khasiana through seeds is demonstrated along with detailed information on precautions to be taken during the adoption of the techniques.

Abstract The conservation status of the five genera and 11 species of palm endemic to the Mascarene Islands (Mauritius, La Réunion and Rodriques) are reviewed. All species are threatened with extinction; nine taxa are classified as Critically Endangered and four as Endangered on the 2000 IUCN Red List. Two taxa survive as single wild specimens (Hyophorbe amaricaulis and Dictyosperma album var. conjugatum); an additional seven taxa have wild populations of 100 or fewer. Although the historical phase of large-scale forest clearance has passed, the remaining palm populations in the Mascarenes are under threat from the effects of population fragmentation, invasive plants and animals, and high levels of seed predation that prevent natural regeneration. The advantages of in situ management for the recovery of these palm populations are discussed. Without a long-term conservation programme, utilising both in situ and ex situ management, extinction of wild populations will occur.

Abstract The infectious chytrid fungus Batrachochytrium salamandrivorans (Bsal) has been responsible for severe population declines of salamander populations in Europe. Serious population declines and loss of urodelan diversity may occur if appropriate action is not taken to mitigate against the further spread and impact of Bsal. We provide an overview of several potential mitigation methods, and describe their possible advantages and limitations. We conclude that long-term, context-dependent, multi-faceted approaches are needed to successfully mitigate adverse effects of Bsal, and that these approaches should be initiated pre-arrival of the pathogen. The establishment of ex situ assurance colonies, or management units, for species threatened with extinction, should be considered as soon as possible. While ex situ conservation and preventive measures aimed at improving biosecurity by limiting amphibian trade may be implemented quickly, major challenges that lie ahead are in designing in situ disease containment and mitigation post-arrival and in increasing public awareness.

AbstractOver the last few decades botanic gardens worldwide have been encouraged to adopt complementary measures for the conservation of plant species from their own regions, combining in situ conservation efforts with ex situ methods, both in cultivation and in storage. This integrated approach is particularly important for botanic gardens in the tropics, which face the challenge of conserving a highly diverse and often threatened flora. We gathered information on the occurrence of threatened species in the natural vegetation reserves of 21 Brazilian botanic gardens. The data were collected from herbarium records in the database of the National Centre for Flora Conservation, and from the available plant inventories of these reserves. The results indicate that 148 species from the List of Threatened Species of Brazilian Flora are recorded as having been collected in the reserves. Of these, 51 species were maintained in the living collections of 18 botanic gardens and 83 species were recorded in federally protected areas. The occurrence of threatened species in the reserves of botanic gardens highlights the scientific value of these areas, as well as their biological, social and cultural importance for conservation. The results may be used to inform the planning of integrated conservation strategies for threatened species.
