ArticleConservation and utilization of natural orchids using a collaborative action model in the Lore Lindu Biosphere Reserve, Sulawesi, Indonesia
XV World Forestry Congress, 2-6 May 2022

No results found.Lore Lindu National Park (LLNP) as the core zone of the Lore Lindu Biosphere Reserve in Central Sulawesi is home to a unique biodiversity. In the last decade, over exploitation of orchids and illegal timber logging caused a reduction of more than 50% of the orchid population and about 10% of orchids diversity in their natural habitat. Nowadays, there are 31 species remaining and 3 of them are endemic to Sulawesi. In 2015, the LLNP authority (BBTNLL) began conducting research on orchid gardens growing in the National Park. Based on the research results the NP authority has built a conservation model for orchids through the education of pupils by combining ex-situ and in-situ conservation efforts through collaborative action methods to increase public awareness and restocking/restoration of orchids to their natural habitat. The NP authority used the model for conserving orchids for an educational program in cooperation with one local senior high school (SMA). The conservation-based education is carried out in four stages; (i) scoping areas and target locations, (ii) preparation of local content education materials, (iii) orchid conservation education and restocking by taking at least 3 samples per species in pure lines), (iv) replicating the results of conservation education as lessons-learned. The result of the implementation of this model is the establishment of an orchid education project based on a conservation agreement between the NP authority and the SMA. Today, students, but also spontaneously formed women's groups cooperate in protecting, breeding and restocking of orchids. In total, students and women groups have already successfully restored 465 orchid plants. Thus, the local population has made an important contribution to the conservation of the remaining 31 orchid species. Of this amount at least 25% was restored in the natural forest to increase the populations in-situ. Further, two other schools adopted this project as best practice for ecological education. Beside all this, some women gain income by selling breed orchids. Thus, beside a high ecological and conservation value, this initiative of the NP auhority also has an economic value. Key words.

ArticleClimatic and anthropogenic challenges in Sundarban biosphere reserve and plausible roads to sustainability
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The Sundarban Biosphere Reserve (SBR), a UNESCO World Heritage site, is the Indian part of the largest pristine mangrove forest in the lower Gangetic Delta. The core area of SBR is the abode of the majestic Royal Bengal Tiger and the transitional area is heavily populated by 4.37 million people (2011 census), 34 % of whom are below the poverty level with an average monthly income of 62 US$. Our recent surveys reveal that a substantial number of poor and marginal people depend on forest goods - honey, crab, fuelwood, shrimp seed, and river fishing for their sustenance and livelihood. However, driven by the global seafood market and local poverty, there has been a significant increase in the aquaculture land from 3.59% in 1999 to 5.52% of total SBR in 2019, engulfing more than 1000 ha of mangrove forest, 2300 ha of mudflat, and 24000 ha of agricultural land, weakening the coastline at many places. SBR is the seat of frequent tropical cyclones and flood surges. Within the last 15 years, 4 super cyclones with floods have ravaged the landscape affecting the vitality and health of both humans and mangroves. Prawn seed and crab collection using thin nylon dragnets are disastrous for mangrove regeneration and restoration damaging seedlings and several aquatics irrevocably with negative impacts on UN SDG 13, 14, and 15. Adding to it, aquaculture ponds of the SBR can emit almost 5,21,02,87,00,000 micromole CO2 per year (22ton CO2 per hour ≈ 1,92,720 ton CO2 per year). The flourishing of aquaculture ponds at the expense of mangroves, hence, not only results in a one-time loss of sequestered carbon by the pre-existing mangroves over centuries but also a land-use which acts as a steady CO2 emitter. For Sustainable development of the Sundarbans, strict enforcement of the existing forest and coastal legislation coupled with the establishment of the state-of-art hatcheries, and promotion of organic shrimp farming preferably with the mangrove-aquaculture farming model is suggested.

DocumentVariability in the early growth of Parkia timoriana (DC.) Merr. from Mount Makiling Forest Reserve, Luzon, Philippines and its applications in conservation and forest restoration
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.This study evaluated the early growth performance of selected mother trees of Parkia timoriana (Fabaceae) and characterized the suitable environmental (soil and light) factors for the growth of the species. P. timoriana seedlings from different mother trees from the Mount Makiling Forest Reserve (MMFR), Luzon, Philippines were grown in two soil media under greenhouse condition and field trial planted in the University of the Philippines Laguna-Quezon Land Grant (LQLG), where P. timoriana is not occurring naturally and soil and climate differ significantly with the MMFR. Early growth performances in height and ground basal diameter (GBD) or root collar diameter (RCD) both in the greenhouse and field trial plot were measured. Nursery-based performance showed that the average RCD was generally higher in MMFR than LQLG soil but the overall difference was not statistically significant. In contrast, overall average height was consistently higher in LQLG than in MMFR soil, but similar to RCD the difference was not statistically significant. Under different light conditions in the field trial, there was significant difference in mortality, tree height, and GBD. The differences in both the height and GBD may be attributed to the genotype of the mother trees, but height can additionally be attributed to the interaction of the genotype and the different light conditions. Results suggest that P. timoriana can be grown in areas of different soil condition, but it requires partial shade in order to achieve its full growth potential during the early stage of its growth. Hence, P. timoriana when used in reforestation or tree planting projects must consider differences in the early growth response of seedlings according to its genotype as well as light conditions. However, it is highly suggested that growth performances among provenances of P. timoriana and other environmental variables that may affect growth of the species should be looked into.
