Trees providing non-timber forest products (NTFPs) are valuable forest resources, and their management can support conservation objectives. We analyzed the abundance of tree species providing NTFPs, recognized by local H’mong people, in both the strictly protected core zone and the low-intensity forest use buffer zone in north-western Vietnam. We identified 249 tree species, of which 48% were classified as NTFP species. The abundance of 35% of the NTFP tree species was significantly correlated with footpaths, indicating an influence of human activity. A multiple logistic regression model indicates that using NTFP trees for food, medicine, and root harvesting, increases the probability of an NTFP tree absence in the buffer zone. In contrast, the high density of species, and collections of fruit, leaf, and resin decrease the probability of an NTFP tree absence in the buffer zone. Further assessment with a logistic model indicated that NTFP use has lower impacts on the tree community than timber use. We think that the parameterized models will enable comparisons of different situations and forest types and be particularly helpful in evaluating potential changes in tree communities over time.

Non Timber Forest Products

Repong Damar is a form of hereditary since the days of the Dutch colonial government owned by the Krui Lampung people in the West Coast. Repong damar functions as a buffer zone in the Bukit Barisan Selatan National Park. The flagship product from Non-Timber Forest Products (NTFPs) in Indonesia found in Krui Pesisir Barat is Damar Mata cat (Shorea javanica). The management and use of resin repong can cause various types of plants. Damar reong found in the Regency of Pesisir Barat has very important benefits for life, and therefore it is necessary to act as a preservation effort for this repong damar to remain sustainable and continue to grow. One of the efforts made is to analyze the diversity of tree species that are in the resin dunk. This study aims to determine the diversity of tree species in the Central Pongir Pongon Repong Pahmungan and Tenumbang Pekon Coastal Equipment and to compare the diversity of tree species in the Central Pekon Pahmungan and South Pekon Tenumbang Pekon Coastal Areas. This research was conducted in August-September 2019 which is located in two locations, namely Tenumbang Pekon, Pesisir Selatan District and Pahmungan Pahmungan Tengah Pesisir Tengah District, Pesisir Barat District. The method used to determine the diversity of tree species using the plot line method where the determination of the plot starting point is done by Systematic sampling with random sampling. Analysis of the data to be used is the relative density (KR), relative frequency (FR), and relative closure area (CR). Importance Value Index (INP) = KR + FR + CR (Indriyanto, 2006). The Diversity Index used is the Shanon Wiener Diversity Index (H '). The results of the research that have been carried out there are 28 species of trees found in Pahonungan Pahmungan, Central Pesisir Tengah and 32 species found in Tenumbang Pekon, Pesisir Selatan District and Diversity of tree species in Pahonungan Pekm Tengah, Pesisir Tengah District, 1.86 and Diversity of tree species in Pekon Tenumbang.

Structured Questionnaire

Les forêts d’Afrique centrale contiennent plusieurs produits d’origine animale et végétale. Les produits d’origine végétale peuvent se distinguer en produits forestiers ligneux et non ligneux. Le présent travail de recherche porte sur l’importance et la gestion durable de quelques Produits Forestiers Non Ligneux (PFNL), notamment l’écorce de trois arbres (Garcinia lucida, Scorodophloeus zenkeri, Alstonia boonei) dans la localité de Ngovayang I. À l’aide d’un questionnaire semi-structuré, les caractéristiques du secteur des PFNL, les stratégies de gestion, ainsi que l’impact de la valorisation des PFNL ont été déterminés. Il ressort des enquêtes que les écorces de ces trois espèces sont connues et utilisées à des fins diverses telles que la consommation, l’automédication et la vente. L’initiation à l’utilisation de l’écorce de ces espèces est liée au sexe et est également fonction de l’âge des enquêtés. Leurs écorces sont approvisionnées sur le marché et vendues en majorité par les hommes. G. lucida et S. zenkeri sont utilisées à des fins nutritionnelles, médicinales et lucratives, tandis qu’Alstonia boonei est utilisée exclusivement à des fins médicinales. Pour des personnes plus jeunes, d’une tranche d’âge comprise entre 15 et 35 ans, l’exploitation de l’écorce de ces trois espèces n’a aucun impact néfaste sur la disponibilité des ressources forestières. S’agissant des personnes âgées de 35 à 65 ans, l’exploitation non contrôlée et l’écorçage anarchique de G. lucida et de S. zenkeri peuvent entrainer leur pénurie et même leur disparition dans cette région. Toutefois, la récolte échelonnée de l’écorce de G. lucida, S. zenkeri et A. boonei est utilisée comme stratégie de gestion de l’écorce de ces arbres dans cette localité.   Central African forests are teemed with several goods of animal and plant origin. Goods of plant origin are forest products and non-timber forest products. This research work focused on the identification and importance of some non-timber forest products (NTFPs), especially the bark of tree species (Garcinia lucida, Scorodophloeus zenkeri and Alstonia boonei) in the locality of Ngovayang I. Using a semi-structured questionnaire, the characteristics of the NTFP sector, management strategies, and the impact of NTFP exploitation were determined in Ngovayang I. Surveys show that the bark of these three species is well known and used for various purposes such as consumption, self-medication and sale. The initiation of the use of the bark of these species is linked to sex and also depends on the age of the respondents. Their bark is supplied on the market and sold mostly by men. G. lucida and S. zenkeri are used for food, medicinal and profit-making purposes, while A. boonei is used exclusively for medicinal purposes. For younger people, aged between 15 and 35 years old, the exploitation of the bark of these three species has no negative impact on forest resources. For old people (35 to 65 years), the uncontrolled exploitation and uncontrolled debarking of G. lucida and S. zenkeri can lead to the shortage and even extinction of these two tree species in the region. However, the planned harvest of the bark of Garcinia lucida, Scorodophloeus zenkeri and Alstonia boonei is used as strategy of management of the bark of these trees in this locality.

Non Timber Forest Products

Non-Timber Forest Products (NTFPs) are the forest products except timber used for various purposes from which economic status of the country can be increased through green growth based economy. The study was conducted in Baghmara Buffer Zone Community Forest for the inventory, to document various uses and find out the preferred NTFPs potential for economic development of Community Forest User Groups. Stratified random sampling was applied in which 50 quadrats of size 25m×20m for trees, 100 subplots of 10m×10m for shrubs and 200 small subplots of 1m×1msize for herbs and climbers were taken. Parameters like density, frequency, abundance, importance value index, diversity index, evenness index and dominance index were calculated to find out the ecological status of NTFPs. Questionnaire survey of 100 households was done for studying different uses and interview with 10 key informants were carried out to identify 10 most preferred NTFPs. Altogether, 109 NTFPs were enumerated. Trewia nudiflora, Clerodendrum viscosum, Imperatacylindrica and Mikania micrantha were dominant tree, shrub, and herb and climber species accordingto Importance value Index (IVI). There is significant difference in density of trees, shrubs, herbs and climbers between different sample quadrats i.e. p value < 0.05. NTFPs found were used for medicine, fodder, food, veterinary, dying, handicrafts, crop management, ornamental, insecticides, construction, beverage, piscicidal, religious and miscellaneous purposes. Calamus tenuis, Curcumalonga, Piper longum, Phyllanthus emblica, Asparagus racemosus, Terminalia bellirica, Terminaliachebula, Bauhinia variegata, Tinospora sinensis and Dryopteris cochleata were ten most preferred Non Timber Forest Products from matrix preference ranking.

Potential Use

Forest is a resources system which has prospective materials to be used for human needs. Local people within everyday life are very dependent on the natural surroundings, as well as the use of nature for human needs tend to increase. The purpose of this research is to do the analysis of vegetation and determine the potential use of non-timber forest products in Kampung Pagai, Airu District, Jayapura. The method used for the analysis of vegetation is the square plot, while the method to figure out the potential of non-timber forest adopts the method developed by Waluyo (2004). The results showed that there are at least 39 species of trees belonging to the 26 families. Regeneration of trees showed the condition which is good based on the diversity of tree species in the Sapling level, especially matoa (Pometia pinnata), kayu besi (Instia bijuga), and various plants of Ficus ssp. The potential uses of non-timber forest are also quite high. Several types of plants can be used as building materials and accessories, medicines, ornaments (including orchids), fruits, and vegetables. Key words: forest, vegetation, non-timber forest product, Airu District, Jayapura.

Baseline Information

Non-timber forest products are non-wooded biological resources derived from both natural and managed forests and other wooded areas. The objective of the study was to perform resource assessment for baseline information on the status and distribution of locally prioritized plant based non-timber forest products in Nuwakot and Sindhupalchok districts of Langtang National Park’s buffer zones. Consultative workshops and forest inventory techniques were applied to collect data. From the consultative workshops 133 species of plants having use value were identifi ed. It was identifi ed that Gaultheria fragrantissima and Edgeworthia gardneri were more potential species for commercial production and utilization. For commercial production and collection of Gaultheria fragrantissima, buffer zone areas of Nuwakot district will be the better place. Similarly, the commercial production and collection of Edgeworthia gardneri will be better in buffer zone areas of Sindhupalchok district.J. Nat. Hist. Mus. Vol. 28, 2014: 102-117

The Village

Non-timber forest products (NTFPs) and some forest tree species are an important source of livelihood to communities. Unfortunately, their potential and uses are much unknown by the population or organization responsible for conservation. It is for this reason that this study was carried out in the village of Minko’o to assess this potential, and to show their importance. A socio-economic survey was carried out in the village and GPS coordinates of the identified NTFPs and forest trees was recorded from the farms/plantations and forest visited. A total of 20 households were surveyed in order to identify the different NTFPs and their utility for the population. Our findings revealed that 50% of the harvest of NTFPs and forest species is done by picking and 45% by collection. Some NTFPs and forest products were known and used by the people. Some of these resources were not known and therefore under exploited. It is the case of Cola (Cola nitida), Soursop (Persea muricata), Akom (Terminalia superba), Mfo (Enantia Chlorantha), Kassimang (Spondias purpurea). Most of NTFPs were grown by the populations and the preferred NTFP was the avocado tree. The forest tree species are mainly used for medicinal purposes. Other trees were used for construction.
