FRM 512 (Forest Protection and Conservation): Tree Diseases Affecting Forest Tree Species
Ten Tree diseases affecting forest tree species A) Common name: Root rot disease Botanical name: Cochliobolus sativus. Literature review: Root rot disease is a disease that attacks the roots of trees growing in wet or damp soil. Prolonged exposure to excess water causes waterlogging, which interferes with aeration of the roots, leading to low oxygenation and decay. Causative Agent: Phytophthora spp. Particularly species P.cinnamomi. Others include Pythium, Rhizoctonia and Fusarium..... B) C...
Parameters of Trucks and Loads in the Transport of Scots Pine Wood Biomass Depending on the Season and Moisture Content of the Load
Abstract: Transport of wood biomass is one of the key operations in forestry and in the wood industry. An important part is the transport of shredded wood, where the most common forms are chips and sawdust. The aim of the research was to present the variability of the total weight of trucks (gross vehicle weight, GVW), the weight of the empty trucks (tare), and loads of chips and sawdust in different periods of the year. Changes in specific parameters were analyzed: GVW; tare weight; trailer...
Spatial Distribution of Forest Reserves and Sawmills in Oyo State, Nigeria
Abstract Geographic Information System (GIS) is a veritable tool for spatial analysis in forestry. The proximity to forest reserves has been considered one of the major factors affecting the spatial distribution of wood based industries. However, information on number of sawmills and spatial distribution of both the forest reserves and sawmill in Oyo Sate is lacking. Hence, this study employed GIS to develop spatial distribution map of forest reserves and sawmills in Oyo State, Nigeria. The ...
What are Forest Reserves and Why Are They Important
Forest reserves are portions of state lands where commercial harvesting of wood products is excluded in order to capture elements of biodiversity that can be missing from sustainably harvested sites. Small (patch) reserves will conserve sensitive, localized resources such as steep slopes, fragile soils, and habitat for certain rare species that benefit from intact forest canopies. Large (matrix) reserves will represent the diversity of relatively un-fragmented forest landscapes remaining in M...
Manual on Introduction to Forest Roads and Considerations for Reduced Impact Logging
Foreword The renewable nature of forests can be conserved indefinitely provided stakeholders act responsibly their interventions in forest resources. One vital and critical aspect of forest management, whatever the objective of management, is the construction of roads and trails. The harvesting of timber in particular leads to a higher density of roads (km/ha) and in addition skid trails at the rate of about 1- 2.5km/100ha; roads are essential for conveying production inputs (machines, fuel,...
The Use of Audiovisuals for Effective Learning Among Various Stakeholders in the Development and Utilisation of Onigambari Forest Reserve, Ibadan, Oyo State
Everybody communicates in one way or the other. It is important in every society to exchange meanings What then is Communication? Communication is a continuous, never-ending means of transferring or passing on messages (ideas, innovations, skills, knowledge or practices from a source to the ultimate users in order to modify the behaviour or reaction of receivers in the desired direction. Questions to Ask Before Communication Takes Place Is the communication to an expert or a general aud...
Write Out the Per Capita Income of 5 Developed and 5 Developing Countries Over the Past 5 Years
ASSIGNMENT Write out the per capita income of 5 developed and 5 developing countries over the past 5 years. --- The primary factor used to distinguish developed countries from developing countries is the Gross Domestic Product (GDP). Per capita is the tally of all the goods and services produced in a country in one year, expressed in U.S. dollars. GDP is calculated by dividing a country’s GDP by its population. For example, a small country with a GDP of $1 billion and a population of 50,0...
