Ulin (Eusideroxylon zwageri) is one of the native plants of Indonesia whose growth is spread in tropical forest, among others in southern Sumatra and Kalimantan. Based on the results of the 1998 Asia Regional Workshop meeting held at the Hanoi (Vietnam) International Union for Conservation of Nature and Natural Resources (IUCN), it was determined that ironwood is on Vulnerable A1cd + 2cd status which means sensitive or is facing a high risk of extinction. Tissue culture is a technique that needs to be applied to overcome the problem of ironwood regeneration initiation. However, the concentrati

The regeneration of many climax species in tropical forest critically depends on adequate seed dispersal and seedling establishment. Here, we report the decreased abundance and increased spatial aggregation of younger trees of the Borneo ironwood ( Eusideroxylon zwageri) in a protected forest in Sabah Malaysia. We observed a high level of seedling herbivory with strong density dependence, likely exacerbated by local aggregation and contributing to the progressively shrinking size distribution. We also note the largely undocumented selective herbivory by sambar deer on E. zwageri seedlings. Thi

The response of tropical trees to the change of light intensity has been reported to be varied among different species. Some reports argued that the growth was increasing parallel to the increasing of light intensity, but other reports mentioned that the sensitivity to the light intensity was depending on the species. Another environmental factor that has been scientifically proven to affect tree growth is humidity. While humidity itself also directly affected by the light intensity in the forest ecosystems. Therefore, it is possible that the growth pattern of trees under different light inten

Abstract Enhancing green open spaces in cities and their buffer areas has gained increasing recognition. While creating a more sustainable, liveable, and comfortable environment, green spaces could also provide an effort for plant domestication and conservation. We consider the potential urban greening and conservation action by planting five tree species consisting of one highly valuable and slow-growing species Eusideroxylon zwageri trees from four different origins and four fast-growing species of Duabanga moluccana, Anthocephalus macrophyllus, Duabanga grandifolia, and kayu papaya at the w

The high conservation status of ironwood (Eusideroxylon zwageri Teijsm & Binn.) causes conservation efforts need to be carried out immediately. Balitek KSDA has carried out ulin conservation efforts by building ulin ex-situ conservation plots in the Samboja KHDTK with seeds from the Sungai Wain, Sangatta and Berau. This study was conducted to evaluate the variation of ironwood plant growth from these three provenances in the Samboja KHDTK. The results showed that the average survival rate of ironwood plant was 79.12% and there were no differences in the three provenances. Plants from Sanga

Abstract Ironwood (Eusideroxylon zwageri) is one of Indonesia’s most economically valuable timber tree species and was listed as Vulnerable in 1998 by the IUCN. To support conservation activities and establish E. zwageri’s plantation, good quality planting stocks should be collected from specific seed sources. Currently, there is only one ironwood seed source in Sumatra that has been registered. This study aimed to assess the potential for an ironwood stand on the KPPN Bulian of the District VIII of PT. Wirakarya Sakti is to be proposed as a seed source. The assessment was conducted on July 20

ABSTRACTBackground: The use of herbal medicinal plants by the community is increasing because the side effects are smaller than chemical-based drugs. One of the medicinal plants is ironwood because of its flavonoid and phenolic compounds which have the potential as antioxidants. Ironwood needs to be known for its toxicity, by performing an oral subchronic toxicity test on the kidneys of wistar rats with urea and creatinine parameters. Objective: Proving that the administration of ironwood bark extract at doses of 524.5 mg/mL, 1151.5 mg/mL, and 1775.5 mg/mL orally for 28 days had no toxic effec
