Info

Na Hang Nature Reserve, Tat Ke Sector 1997 was seen and heard chasing a deer through the forest. The District Rangers Office confirmed this. The stream flowing through Tat Ke village has been overfished using the poison leaf of Momordica cochinchinensis (Family Cucurbitaceae). Only small fish now populate these waters. The Nang and Gam rivers are fished using net and lines and electric methods. Some explosive fishing is reputably still carried out on a small scale although it was not observed. 12.3.4.2 Food and medicine The following products were observed to be taken from the forest during the study period: • Bamboo (Poaceae) shoots were frequently collected during the study period; this was the main season for its harvest. • Polygonum hydropiper (Polygonaceae) is used as a vegetable to stuff bamboo shoots. • Arenga pinnata (Arecaceae) is used by some houses in Lung Pang in the production of rice wine. • The Hmong villagers use Dioscoria alata (Dioscoriaceae) from the forest to supplement their diet when maize reserves are finished. • Tay villagers at Tat Ke collected Scoparia dulsis (Scrophulariaceae) for use as a herbal tea; in addition to domestic use, the herb was dried and sold at Na Hang. • Herbal medicines are still used for snake bites, skin infections, rashes and other minor ailments. Ocimum tomentosus (Lamiaceae) is used in the cure of dermatological problems; Fibraurea tinctoria (Menispermaceae) is used as an antibiotic during the treatment of animal bites and cuts. Alocasia hainanica (Araceae) is used to reduce swelling around cuts and bruises. 12.3.4.3 Timber There is no evidence to suggest clear-cut logging for timber occurs at present. Selective logging does occur on a small scale for domestic use, and is carried out using traditional methods. No chainsaws or heavy machinery are used. The practice is monitored and controlled; permission to log timber for the construction of houses has to be obtained from the district committee beforehand. Species used in the construction of houses include: • Woody plants for the construction of the frame : Markhamia stipulata (Bignoniaceae) Fagraea fragans (Loganiaceae) Erythrophloeum fordii (Fabaceae) Artocarpus heterophyllus (Moraceae) Burretiodendron hsienmu (Tiliaceae) Frontier-Vietnam Environment Research Report 9 48
Na Hang Nature Reserve, Tat Ke Sector 1997 Melia azedarach (Meliaceae) Chukrasia tabularis (Meliaceae) Shorea stellata (Dipterocarpaceae) Garcinia tonkinensis (Clusiaceae) Vatica tonkinensis(Dipterocarpaceae) • For the walls : Bambusa blumeana Gigantochloa laevis Dendrocalamus membranaceus Dendrocalamus latiflorus (all Poaceae) • For the roof : Imperata cylindrica Dendrocalamus patellarus Dendrocalamus membranaceus (all Poaceae) 12.3.4.4 Other Dead wood and bamboo is collected from the forests surrounding the villages and is used as the main source of fuel for cooking. The families interviewed estimated that between 1-2 m 3 were used each month, although this is considered to be an underestimate due to their belief that firewood may be taxed in the near future. Bat guano is collected from local caves and used as fertiliser by some families. 12.3.5 Peoples attitudes to conservation The Tay people of Tat Ke village appear to have the greatest amount of foresight and respect for the reserve, seeing it as an important source of income. They are keen to be involved with any future plans for development. They are concerned about the amount of erosion occuring in the reserve, which is particularly evident along the path from Tat Ke to the Nang River. The Dao appear to have little respect for the reserve, and no idea of its present importance. The village leader had no clear plans for the village although he did express concern over the amount of alcohol the local men were drinking. No mention of the forest or reserve was made. The Hmong lead a very simple lifestyle, and appear content with sufficient food to live on. They are the least affluent of the minorities. They have a strong respect for the ideas of Ho Chi Minh (especially with regards to the environment) although their poverty prevents them from practising these ideals.
