Accepted 31 May, 2013 Forest trees are the integral part of human society. Forest trees provide both direct and indirect benefits to humans. The number of products provided by trees worldwide is extensive. The wood, bark, leaves, fruits, seeds and roots of trees yield food, fodder, shelter, medicine, fibre, resin, oils and other numerous products used for subsistence of people living in rural and tribal areas. There is a great international interest in the so-called multipurpose trees, but in practice, virtually all tree species can be used for more than one purpose. In some areas in India, the life and livelihood of the tribes depend on trees, as they provide all the commodities required by them in their day to day life. However, in recent days, there is rapid depletion of forest covers, which results in loss of these valuable trees, thereby affecting the livelihood and culture of the tribes. In this regard, the paper is an attempt to study, based on sustainable development strategy of forest resources, the ethnobotany on multiple uses of tree species by the tribes of Kalahandi District, Orissa, India. The study was carried out during 1998-1999, with four tribal groups named Gonda, Kandha, Kutia Kandha and Shabara, in four community development blocks of the district. The multiple uses of 40 tree species belonging to 22 families were documented. Medicinal and non-medicinal usages were recorded. Key words: Forest trees, ethnobotany, medicinal uses, Kalahandi, tribal. INTRODUCTION It has never been more urgent than now to realize the full for multiple uses.

A total of 103 exotic plant species (99 species of angiosperms and 4 gymnosperms) belonging to 90 genera and 43 families were recorded through transect method from the study area. Among the exotics, tree species constitute the major category (46 species, 21 families) followed by shrubs (33 species, 18 families), herbs (21 species, 17 families) and climbers (3 species, 3 families). Mimosaceae family was represented by maximum (9) exotic plant species followed by Caesalpiniaceae (8), Myrtaceae (8) and Malvaceae (7). Most of the exotic plants were introduced in the eco-park after its establishment. Exotic tree species are given priority as the dominant plantation species in the eco-park area because of their short rotation, wider adaptability and faster growth. A total of 74 tree species (52 native and 22 exotic) belonging to 33 families were recorded through random sampling method in the eco-park.

The annual estimated consumption of traditional fuel is 11.3 million m3 of which dung and farm residues supply 28% in the terai and 18% in the hills.

This is followed by a description of the structure and contents of the present volume and a citation of sources used to compile the present checklist. 1. Forest habitats and ecoregions in Lao PDR 1.1. Forest habitats Forest classifications can be vegetation-related (which implies that the factors used to distinguish forests are the physiognomic or floristic characteristics of the vegetation), biophysically- and climate-related (where broad environmental or geographic characteristics become the distinguishing factors), or management- related (which involves utilizing combinations of vegetation and non-vegetation criteria). These modes of classification are scale-specific: while global-scale classifications are largely based on climatic criteria such as rainfall and temperature, classification systems used at country- or smaller regional-level scales emphasise floristic and physiognomic characteristics as well as physical site factors (Wong, Delang, Schmidt-Vogt, 2007). These latter variables were taken into account by the National Office of Forest Inventory and Planning (NOFIP) when it classified the forests of Lao PDR (Manivong and Sandewall, 1992).

Chemistry Central Journal (2016) 10:48 DOI 10.1186/s13065-016-0197-5 RESEARCH ARTICLE Open Access Anti‑cholinesterases and memory improving effects of Vietnamese Xylia xylocarpa Linh My Thi Lam1, Mai Thanh Thi Nguyen1,6*, Hai Xuan Nguyen1, Phu Hoang Dang1, Nhan Trung Nguyen1, Hung Manh Tran1, Hoa Thi Nguyen2, Nui Minh Nguyen2, Byung Sun Min3, Jeong Ah Kim4, Jae Sue Choi5 and Mao Van Can2* Abstract Background: Alzheimer’s disease (AD) is the most common cause of dementia among the elderly and is character- ized by loss of memory and other cognitive functions. An increase in AChE (a key enzyme in the cholinergic nervous system) levels around β-amyloid plaques and neurofibrillary tangles is a common feature of AD neuropathology. Amnesic effects of scopolamine (acetylcholine receptor antagonist) can be investigated in various behavioral tests such as Morris water maze, object recognition, Y-maze, and passive avoidance. In the scope of this paper, we report the anti-AChE, anti-BChE properties of the isolated compound and the in vivo effects of the methanolic extract of Xylia xylocarpa (MEXX) on scopolamine-induced memory deficit. Results: In further phytochemistry study, a new hopan-type triterpenoid, (3β)-hopan-3-ol-28,22-olide (1), together with twenty known compounds were isolated (2–21). Compound 1, 2, 4, 5, 7–9, and 11–13 exhibited potent acetyl- cholinesterase (AChE) inhibitory activity in a concentration-dependent manner with IC50 values ranging from 54.4 to 94.6 μM. Compound 13 was also shown anti-butyrylcholinesterase (BChE) activity with an IC50 value of 42.7 μM.

    NAT. HIST. BULL. SIAM SOC. 54(2): 239–260, 2006 SAVING A FOREST: THE COMPOSITION AND STRUCTURE OF A DECIDUOUS FOREST UNDER COMMUNITY MANAGEMENT IN NORTHEAST THAILAND Md. Enamul Kabir1 and Edward L. Webb1 ABSTRACT This study investigated the composition and structure of a 560-ha deciduous forest in Northeast Thailand that has been under community protection and management since the 1980s. The site had a long history of timber harvesting for local and regional needs until the 1970s, with strict protection against tree cutting beginning in the late 1980s. We established 31 temporary circular plots in the forest to sample trees≥ 10 cm diameter (dbh) (0.97 ha), saplings 2.5–9.9 cm dbh (0.09 ha), seedlings< 2.5 cm dbh (0.01 ha), and vines/woody climbers. We recorded 97 species in 48 families. Sindora siamensis var. siamensis, Xylia xylocarpa var. kerrii, Erythrophloeum succirubrum, and Bauhinia saccocalyx were the most important species in this forest, and accounted for about 92% of all recorded stems≥ 2.5 cm dbh. Leguminosae, Papilionoideae was the most abundant family in this forest. Species composition and stand structure reflected the forest’s degraded condition from persistent disturbances. However, the forest appeared to be regenerating and the villagers had been able to harvest several non-timber forest products to supplement their livelihoods. We compared species composition and forest structure of Khok Bung Preu forest with other similar forests types in Thailand. Khok Bung Preu was less diverse than forests under protection management in Thailand. Without the initiative of the community leaders, the existing forest would have been converted to agriculture in the 1970s.
