Abstract: Iroko gall bug, Phytolyma species is a major pest of Milicia excelsa which has hindered the establishment of Milicia plantations in many West African countries. To date, the genus Phytolyma consists of Phytolyma lata (Scot), Phytolyma fusca (Walker) Phytolyma minuta (Hollis) and Phytolyma tuberculata (Alibert). In Nigeria, there is no clear record of the Phytolyma spp found in the country. This has become a major concern due to irregularities in researchers’ report of species pre...
Abstract: Neem tree (Azadirachta indica A. Juss ) is a multipurpose tree widely planted in Sudan. Recently the tree has been singled as a high priority species for natural pesticide this gives it an economic importance. Fresh seeds germinate readily if sown directly after collection but they lose their viability very quickly (4-12 weeks). This study was conducted at the National Tree Seed Centre, Soba-Sudan (June-December 1995) and University of Gezira farm (Dec.94 -Jan.1996). The main objec...
ABSTRACT Assessment of forest diversity, perception of community towards forest and socioeconomic interaction is very important in order to maintain better forest management. This study was carried out to assess indigenous woody species diversity, socio-economic importance of the forests & drivers of degradation & deforestation in Tolitokal forest. Systematic sampling techniques were applied to collect vegetation data. Six transect lines were laid along the gradient and a total of 30 plots ...
A forest is a large area of land covered with trees and bushes. It can also be defined as an area of land with high density of trees or a large expense of land covered with trees and a home for wild animals. All forests are either natural or artificial. The natural forest exists on their own while the artificial ones are established and managed by man. Forests cover about 30 percent of the earth’s surface and contain about 3 trillion trees. They exist in dry, wet, freezing cold, and scorchi...
ABSTRACT This investigation dealt with determination of some properties and suitable uses for four lesser used wood species grown in the Blue Nile State. Four of the secondary wood species which are available in reasonable quantities in Blue Nile State, but are not in common use were selected for this investigation. The selected species comprised: Sterculia setigra (tartar), Acacia polyacantha subsp. campylacantha, (kakamut), Acacia seyal var. seyal (talh) and Diospyros mespiliformis (goghan...
ABSTRACT Economic of Eucalyptus Private Forests Case Study of Nertitei and Zalingei Localities In Central Darfur State This study was conducted during the period 2015 - 2017 in Nertitei and Zalingei localities purposely, because most of the Eucalyptus private forests of the central Darfur state found in those two localities. The overall objective is to study the economic aspects of Eucalyptus private forests while the specific objectives were include: measuring the costs, production, retu...
ABSTRACT Research on markets and marketing of some non-timber forest products (NTFPs) was carried out in selected locations of Osun State. The NTFPs considered are chewing sticks such as Massularia acuminata and bush meat like Thryonomys swinderianus, representing both the flora and fauna aspects of NTFPs, respectively. Five Local Government Areas were randomly selected, namely; Odo-otin, Boripe, Iwo, Irewole and Atakunmosa for the research purpose. A total of 300 questionnaires were administ...
ABSTRACT This study assessed the effects of integrating Gliricidia sepium, rainwater harvesting known as chololo pits and planting times on soil moisture, maize growth and yield in Kongwa District, Dodoma, Tanzania. A factorial experiment was adopted to test the effects of planting times (Early, Normal and Late planting), and CSA practices (Maize monoculture, Gliricida sepium intercropping and intercropping with G. sepium and chololo pits. The planting times were Mid-November to Mid-Decembe...
ABSTRACT On-farm tree planting has been practiced all over the world in order to supplement reserved forests in terms of wood products. On-farm tree planting was a strategy to reduce pressure in the Amani Nature Reserve (ANR), which is biologically important in the Eastern Arc Mountains and globally at large. The objectives of this study were to assess the contribution of on-farm trees in conservation of the biodiversity of ANR. Measurements were taken from total of 135 on-farm plots measuri...
ABSTRACT There is no doubt that REDD+ payments can do many activities that lead to deforestation and forest degradation less attractive. However, countries considering participating in REDD+ mechanism, need information on what it would cost them to reduce emissions from deforestation and forest degradation. This study was delimited to estimate transaction costs of REDD+ project with the Advancing REDD+ in Kolo Hill pilot project in Kondoa District as a case study. Socio-economic and biophys...
ABSTRACT A study was conducted at Meru/Usa forest plantation to determine quality, stocking and yield of Pinus patula and factors influencing them. The Meru/Usa forest plantation compartments were categorized into affected and non – affected by root disease and insect defoliators. Systematic sampling method was used to align transect and plots in the compartment. 198 sample plots of 0.04ha were laid and measurements taken for estimation of stem quality, stocking, basal area and volume. The...
ABSTRACT Forests and water are important Common Pool Resources (CPRs) in the Uluguru Mountains (UMs). Water connects socio-economic groups of different altitudinal zonation namely upstream and downstream with multiple uses and conflicting interests. Researches have been done on ecosystem value, CPRs depletions and the role of socioeconomic incentives in biodiversity conservation but little is known about power relations underlying upstream and downstream CPRs users. This study therefore, was...
ABSTRACT The study was conducted to determine the quantity of timber and extent of illegal timber harvesting in Eastern Arc Mountains. Data were collected using three techniques: desktop review which was used to collect information on timber stocks from two studies in EAMs while socio-economic and ecological surveys were employed to collect information on timber disturbances and timber stocks harvested illegally in NFR. Data analysis involved use of Microsoft excel and Statistical Package fo...
ABSTRACT The main objective of this study was to assess the opportunity costs of REDD+ to the communities of Mufindi District. The specific objectives were, to identify and assess the economic value of alternative land use, the aboveground carbon stock of the sampled forest (Idewa Forest Reserve) under PFM, the profitability of each land use and compare with the REDD+ incentives, and the willingness to accept (WTA) of the communities towards REDD+. Structured and semi structured questionnair...
ABSTRACT Although future increase in timber supply in many countries is expected to come from agroforestry, the problem of on farm timber sawing, physical strain on sawyers caused by “Pitsawing” has to be addressed, to increase timber sawing productivity. This study was aimed at analyzing the productivity and energy expenditure by sawyers when using Traditional Pitsawing Platforms (PSP) and Portable Steel Log Sawing Platforms (PLSP) in agroforestry farms in Kiruweni and Nduweni villages...
