Purwodadi Botanic Garden (KR Purwodadi) is an ex situ conservation institution for dry climate lowland plants aiming at saving and protecting biodiversity from extinction. In supporting ex situ conservation efforts, plant exploration activities in their natural habitat need to be carried out. Alas Purwo National Park has a lowland forest area with abundant plant diversity. In addition to functioning as a conservation forest, this area is also a natural and religious tourist attraction, so it is likely to undergo ecosystem damage. Therefore, this plant diversity study with the activity of plants exploration and collection was carried out for the purpose of ex situ conservation in KR Purwodadi. This study was conducted in August to September 2019 using an explorative method. A total of 24 species were obtained, of which 8 species were not yet cultivated by KR Purwodadi. Besides, there were 5 species included in the IUCN red list, namely Aglaonema simplex, Brucea javanica, Cycas rumphii, Melanolepis multiglandulosa, and Musa acuminata. This study has increased the number of plant collections in KR Purwodadi and contribute positively to the comprehensiveness of plant species data in Alas Purwo National Park.

<p class="IsiAbstrakIndo"><span lang="EN-GB">Mount Seblat, as part a of Kerinci Seblat National Park (KSNP), is a pristine and natural mountain, particularly from disturbances and destructions by human activities. Nevertheless, the richness of biological resources especially plant diversity.in this area has not been more explored. The purpose of this study was to conduct an inventory of plant diversity and to determine the plant species composition. The inventory activities were conducted by plants collection along the ascent route. The results were then be maintained through ex situ conservation method in Cibodas Botanical Garden (CBG). The study was conducted by exploratory method, from Seblat Ulu Village (641 m asl) up to altitude of 1,037 m asl. There were 18 points of plant sample observation with an area of 5 x 5 square meters per point. Plant collection obtained 380 specimens. Five groups of most collected plants were Lauraceae (18 species), Rubiaceae (8 species), Anacardiaceae (6 species), Annonaceae (5 species), and Fagaceae (4 species). In order to enrich the plants collection as well as conduct the ex situ conservation effort, plants from Orchidaceae were also collected which resulted in 33 species. These results were an important initial inventory of plant diversity of Mount Seblat, considering that there was no record as well as very limited current information. When the environment disturbance tends to increase, this information may act as a reference and an initial database to develop plants conservation effort and strategy in the future.</span></p>

Abstract. Rachmat HH, Fambayun RA, Yulita KS, Susilowati A. 2020. Ex-situ conservation and management of dipterocarps genetic resources through seedlings collections and nursery establishment. Biodiversitas 21: 556-563. Dipterocarpaceae is a pantropical tree family that spread throughout Asia, including Indonesia. Dipterocarps species are highly valued for their timber. However, their existence is threatened due to illegal logging, forest degradation, and land conversion, result in population reduction in their natural habitat. Conservation nursery is one of germplasm conservation concepts that contain a living collection of endangered, commercially valuable, and multi-purpose tree species. Related to this nursery concept, Forest Research and Development Agency (FORDA) collaborated with Komatsu established a KoFCo nursery (Komatsu- FORDA Conservation Nursery). The establishment of this nursery was by field collection of dipterocarps species as targeted species, followed by sowing and acclimatization for seed and wildings, vegetative propagation using the KOFFCO cutting system, and nursing (watering, weeding, fertilizing, and soil change). At present, the KoFCo nursery has ca. 13,000 individuals of nine genera of dipterocarps seedlings originated from fifteen provinces in Indonesia. Of these, 76 species (68%) are categorized as threatened based on the IUCN red-list category and criteria. Hence, more than 60% of these threatened species were conserved and well-managed through KoFCo nursery. Seedlings collection and KoFCo nursery, therefore, play a vital role and support in ex-situ conservation effort and management of dipterocarps genetic resources.

Abstract: The threats to the plant biodiversity become more advance along with rapid degradation of the natural habitat. Plants preservation needs accompaniment between in-situ and ex-situ conservation altogether. The ex-situ plant conservation plays more important roles in order to help conserve threatened plant species. Cibodas Botanic Garden (CBG) is a government institution which has the main assignment on ex-situ plant conservation, especially tropical mountainous plants. In the last decade, CBG has conducted exploration and plants collection in order to retrieve them from the destructive pressures in their habitat. This study aimed to asses the CBG’s contribution to ex-situ plant conservation through the addition number of planted plants and to describe the important value to conservation. The study conducted through a quantitative descriptive method, based on data inventory of the newly planted plant in the garden from 2008 to 2018. This also assessed the increasing collection of each year and descriptively explaining the background data, species variety, and their conservation status. The results described that the additional number was 473 specimens and the average increase was 43 specimens per-year. These originated from exploration and plants collection 248 specimens, donation 217 specimens, self-propagation seven specimens, and one specimen from seeds exchange. The most planted was Nepenthaceae with 84 specimens, secondly Phillantaceae with 21 specimens, and Lauraceae 15 specimens. There were 116 species (152 specimens) which have conservation status. These expected to be a comprehensive description of the CBG’s plant collection and meaningful for the conservation efforts in general.Keywords: ex-situ plant conservation; garden collection; Cibodas Botanic Garden (CBG)

Citropsis articulata is a medicinal plant that is increasingly threatened by unsustainable methods of harvesting and habitat degradation. Owing to the fact that this plant species is highly utilized for herbal medicine and is currently restricted to a few forest reserves in Uganda, this has significant implications for ex situ conservation. Therefore, the aim of this study was to assess how physiographical factors influence the occurrence and distribution of C. articulata in the three forest reserves in Uganda, namely, Budongo, Mabira, and Kibale National Park. The study was carried out in 15 compartmental sites in each of the three forests. In each compartmental site, 4 plots of 60 m × 60 m were systematically established, and within each plot, 4 subplots each of size 20 m × 20 m were randomly setup. A total of 240 subplots were assessed for occurrence of Citropsis articulata in each forest. The results indicated a significant ( p < 0.05 ) variation in the density of C. articulata with the highest recorded in Kibale National Park. Citropsis articulata generally occurred at moderate altitudinal landscapes (overall elevation = 1200.0 ± 20.73 m) with soils that are moderately acidic (overall pH = 5.7 ± 0.10), low in salinity (overall salinity = 84.0 ± 3.84 mg/l), and moderate levels of macro- and micronutrients. Citropsis articulata was generally associated with plant communities dominated by canopy tree species of genera such as Chryosphyllum, Celtis, Markhamia, Cynometra, Lasiodiscus, Trilepisium, Funtumia, and Diospyros, thus suggesting that C. articulata is a shade-tolerant species. Establishing the ecological requirements of this plant species among other things informs the potential for ex situ production of this plant. This will not only provide alternative sources of plant harvest but also go a long way in relieving the current harvest pressures exerted on the conserved wild populations of this plant species.

In this study, we observed the flowering phenology, breeding system, pollination and seed germination of four species of Calligonum (C. calliphysa, C. rubicundum, C. densum and C. ebinuricum) in the Turpan Eremophytes Botanic Garden, China. Our results showed that the species had overlapping flowering phenologies and were pollinated by similar pollination agents. Their breeding systems were self-compatible, and with signs of outbreeding, but not of hybridization with each other; the main isolation mechanism was post-zygotic isolation and they also had high seed germination rates. Therefore, they are suited to ex situ conservation in the Turpan Eremophytes Botanic Garden, and can supply sufficient seeds for renewal populations and the conservation of germplasm resources. Furthermore, these results provide theoretical support for the construction of a national germplasm resource garden of Calligonum, and for the introduction to the garden of other eremophyteplants and their conservation.

Seeds are the most effective and thriving propagation material of Salacia. As part of ex-situ conservation programme, four highly sought Salacia species, viz., Salacia brunoniana Wight & Arn., Salacia fruticosa Wall. Salacia malabarica Gamble and Salacia oblonga Wall. through fruit, seed and seedling characterization was carried out. For this, phenology and morphology of fruits and seeds with reference to polymorphism were documented. Effect of fresh and desiccated moisture content especially that of critical moisture were tested to understand the extent of viability of seeds. Since, these species became threatened in their natural habitat; attempts were made to standardize their seed germination characters and seedlings were raised. Seedling characters along with seedling vigour were documented up to 6 leaf stage and also an identification key was made based on their seedling characters which would aid in the demarcation of the species at their juvenile stage.

The endangered alpine plant Aconitum heterophyllum was conserved under ex situ conditions (greenhouse and open) of Palampur by overcoming seed dormancy and plant establishment through hot water treatment (40–60 °C for 30–120 s) of seeds. High seed germination (88 and 76%) was obtained when seeds were treated with hot water at 45 and 50 °C for 90 s. Correlation studies also revealed that treatment enhanced vegetative growth and reproductive yield of the plants. The total alkaloid content of the roots and rhizomes of the plants growing under ex situ conditions was lower than the ones collected from the natural habitat in the 1-year-old plants. However, in the 2-year-old plants, it was almost at par with the ones collected from nature. The life cycle of the plants growing under ex situ conditions also did not vary largely from the plants growing under in situ conditions. Therefore, the present study indicates the successful adaptation of A. heterophyllum plants in conditions other than their natural habitat and hence its potential for sustainable commercialization.
