(Ntfp) in Liberia AN ENVIRONMENTAL AND ECONOMIC APPROACH TO THE DEVELOPMENT AND SUSTAINABLE EXPLOITATION OF NON-TIMBER FOREST PRODUCTS (NTFP) IN LIBERIA By LARRY CLARENCE HWANG A dissertation submitted to the Graduate School-New Brunswick Rutgers, The State University of New Jersey In partial fulfillment of the requirements For the degree of Doctor of Philosophy Graduate Program in Plant Biology Written under the direction of James E. Simon And approved by _________________________________________________ _________________________________________________ _________________________________________________ _________________________________________________ New Brunswick, New Jersey October 2017 ABSTRACT OF THE DISSERTATION An Environmental and Economic Approach to the Development and Sustainable Exploitation of Non-Timber Forest Products (NTFP) in Liberia by LARRY C. HWANG Dissertation Director: James E. Simon Forests have historically contributed immensely to influence patterns of social, economic, and environmental development, supporting livelihoods, aiding construction of economic change, and encouraging sustainable growth. The use of NTFP for the livelihood and subsistence of forest community dwellers have long existed in Liberia; with use, collection, and local/regional trade in NTFP still an ongoing activities of rural communities. This study aimed to investigate the environmental and economic approaches that lead to the sustainable management exploitation and development of NTFP in Liberia. Using household information from different socio-economic societies, knowledge based NTFP socioeconomics population, as well as abundance and usefulness of the resources were obtained through the use of ethnobotanical survey on use of NTFP in 82 rural communities within seven counties in Liberia. 1,165 survey participants, with 114 plant species listed as valuable NTFP. The socioeconomic characteristics of 255 local community people provided collection practice information on NTFP, impact and threats due to collection, and their income generation. ii Traditional and environmental sustainable harvesting methods on the collection of two leading NTFPs – Griffonia simplicifolia and Xylopia aethiopica – were conducted and assessed. Results show an environmental sustainable harvesting method that minimizes damage/destruction to plant species and population yet allows for efficient product harvest and yield procurement. Domestic value chain study for three leading NTFP in Liberia: Griffonia (Griffonia simplicifolia), West African Black Pepper (Piper guineense) and Country Spice (Xylopia aethiopica), investigated 140 stakeholders who were mainly agents and subagents through survey interviews to provide comprehensive knowledge on selected NTFP from collection to consumer. Resource inventory of Griffonia simplicifolia in Liberia concentrated on the distribution, abundance and the population structure of Griffonia, thereby providing full ecological inventory information on Griffonia as fundamental for assessing conservation status of wild populations. Enhancing germination of Griffonia simplicifolia seed for forest enrichment was assessed using simple tools for seed germination. Seedlings were also introduced in natural habitat to monitor growth habits of transferred plant into local habitat and found that Griffonia has high survival (92% - 95%) in new habitat. Developing quality standards and new products, physico-chemical characterizations of the Liberian spices were analyzed along with those from Ghana. These qualities could set standards for trading of individual product that are used as spices in Liberia and other West African countries. X. aethiopica seeds were chemically characterized for new product development. iii Dedication To my mother, Mother Nancy E. Masaline, for her untiring and steadfast support throughout my life, instilling in me the virtues of uprightness, integrity, respectability, hardwork, and love that made it possible for me to have reached thus far.

  • Mallotus Glomerulatus (Euphorbiaceae Sensu Stricto), a New Species: Description, Pollen and Phylogenetic Position
    THAI FOR. BULL. (BOT.) 32: 173–178. 2004. Mallotus glomerulatus (Euphorbiaceae sensu stricto), a new species: description, pollen and phylogenetic position PETER C. VAN WELZEN*, RAYMOND W.J.M. VAN DER HAM*& KRISTO K.M. KULJU* INTRODUCTION A field trip by several staff members of the Forest Herbarium in Bangkok (BKF) to Phu Langka National Park in Nakhon Phanom Province resulted in the discovery of an unusual undershrub up to 1.5 m high and with the typical ‘explosively’ dehiscent fruits of Euphorbiaceae. The two plants showed a unique combination of characters: opposite leaves, stellate hairs, two apical, axillary ‘fruiting columns’ (no real inflorescences), smooth carpels, and a single ovule per locule (typical for the Euphorbiaceae s.s.: subfamilies Acalyphoideae, Crotonoideae, and Euphorbioideae). A year later, other staff members of BKF collected the staminate flowers, which were present in shortly peduncled glomerules. This inflorescence type is quite common in subfamily Phyllanthoideae (now often referred to at the family level as Phyllanthaceae), but all representatives of this (sub)family have two ovules per locule. Thus, the presence of glomerules makes the set of characters unique and we consider the unidentified plant to be a new species. The new species resembles the genus Mallotus in having extrafloral nectaries in the form of round or oval glands on the upper leaf surface, stellate hairs and short, terminal pistillate inflorescences reduced to a single flower. In Thailand the latter character is present in M. calocarpus Airy Shaw. The new species also resembles M. calocarpus in the smooth, unarmed fruits, the penninerved (not triplinerved) leaf blade, short staminate inflorescences (though no glomerules in M.

  • The Woods of Liberia
    THE WOODS OF LIBERIA October 1959 No. 2159 UNITED STATES DEPARTMENT OF AGRICULTURE FOREST PRODUCTS LABORATORY FOREST SERVICE MADISON 5, WISCONSIN In Cooperation with the University of Wisconsin THE WOODS OF LIBERIA1 By JEANNETTE M. KRYN, Botanist and E. W. FOBES, Forester Forest Products Laboratory,2 Forest Service U. S. Department of Agriculture - - - - Introduction The forests of Liberia represent a valuable resource to that country-- especially so because they are renewable. Under good management, these forests will continue to supply mankind with products long after mined resources are exhausted. The vast treeless areas elsewhere in Africa give added emphasis to the economic significance of the forests of Liberia and its neighboring countries in West Africa. The mature forests of Liberia are composed entirely of broadleaf or hardwood tree species. These forests probably covered more than 90 percent of the country in the past, but only about one-third is now covered with them. Another one-third is covered with young forests or reproduction referred to as low bush. The mature, or "high," forests are typical of tropical evergreen or rain forests where rainfall exceeds 60 inches per year without pro­ longed dry periods. Certain species of trees in these forests, such as the cotton tree, are deciduous even when growing in the coastal area of heaviest rainfall, which averages about 190 inches per year. Deciduous species become more prevalent as the rainfall decreases in the interior, where the driest areas average about 70 inches per year. 1The information here reported was prepared in cooperation with the International Cooperation Administration. 2 Maintained at Madison, Wis., in cooperation with the University of Wisconsin.

E-mail: [email protected] Received: October 4, 2014 Accepted: October 21, 2014 doi:10.5296/jbls.v6i1.6399 URL: http://dx.doi.org/10.5296/jbls.v6i1.6399 Abstract Okoubaka aubrevillei is the largest parasitic plant known to man. It is a tropical tree species distributed within West and Central Africa. Concerns were drawn to the tree because of its rarity, disjunct distribution in all its native range, paucity of published scientific information and its hemi-parasitic potentials. This article gathered and synthesized all existing scientific information on the tree to provide a solid foundation for further research on the tree. This article provided detailed information on its name etymology, taxonomic history, and geographical distribution including new locations for the tree, ecological significance and behaviour within its range, supported with an updated map illustrating its distribution within West and Central Africa. The possible causes of its rarity in its range were identified and its hemi-parasitic behaviour was hypothesized. In addition, ethnobotanical uses of the tree, symbolism and dendrolatry, and its significance in modern medicine were extensively discussed. The paper concluded with highlights on prospects for immediate conservation, management and research focus areas for the tree species.
