Scientists have underlined that the increasing abundance of roe deer appears to be having an impact on woodlands. Indeed, official data collected from the 35 sites of the United Kingdom have shown an apparent relationship between increasing roe deer density and a decrease in shrub diversity and cover. More importantly, research and findings have laid emphasis on the fact that overgrazing by deer had a knock-on effect that undermined woodland ecologies. In addition to this scientific researchers have mentioned that deers often have specific impacts on vulnerable habitat as well as agriculture and forestry specially since the animals tend to range over large areas and need to be managed on a landscape scale, with collaboration between landowners. It is crucial to note that ecologists have warned that the threat from deer to woodlands consist of a number of factors - a reduction in the growth and density of saplings, bark damage and a change in the composition of under-storey vegetation. In-depth research have demonstrated that there are more than 74, 000 roe deers which are killed every year...

Major-General Sir Newton James Moore KCMG (17 May 1870 28 October 1936), was the eighth Premier of Western Australia and a member of the House of Commons of the United Kingdom from 1918 to 1932. Newton Moore was born in Fremantle, Western Australia, son of James Moore, auctioneer and later mayor of Bunbury, and Elizabeth Dawson, schoolteacher. He was educated at Arthur Street Primary School in Bunbury before attending Prince Alfred College in Adelaide, South Australia. In 1886 he was apprenticed as a surveyor to Alexander Forrest. After qualifying in 1894, he worked as a contract surveyor in and around the Bunbury area. In April 1898 he married Isabella Lowrie, sister of William Lowrie. In 1899 Moore was elected to the Bunbury Municipal Council, and was Mayor of Bunbury from 1900 to 1904. In 1903 he was also a member of the Royal Commission on Forestry, and during 1904 and 1905 he was President of the Municipal Association of Western Australia.

The International Energy Agency Bioenergy Agreement was initiated as the Forestry Energy Agreement in 1978. It was expanded in 1986 to form the Bioenergy Agreement. Since that time the Agreement has thrived with some fifteen countries (Austria, Belgium, Canada, Denmark, Finland, Italy, Japan, Netherlands, New Zealand, Norway, Sweden, Switzerland, United Kingdom, United States and the CEC) currently being signatories. The objective of the Agreement is to establish increased programme and project cooperation between the participants in the field of bioenergy. The environmental consequences of intensive forest harvesting have been the subject of intense interest for the Agreement from its initiation. This interest was formulated as a Cooperative Project under the Forestry Energy Agreement in 1984. It developed further under each of the subsequent three-year Tasks of the Bioenergy Agreement (Task III, Activity 3 'Nutritional consequences of intensive forest harvesting on site productivity', Task VI, Activity 6 'Environmental impacts of harvesting' and more recently Task IX, Activity 4 'Environmental impacts of intensive harvesting'. The work has been supported by five main countries from within the Bioenergy Agreement: Canada, New Zealand, Sweden, UK, and USA. The continued work has resulted in a significant network of scientists work ing together towards a common objective - that of generating a better under standing of the processes involved in nutrient cycling and the development of management regimes which will maintain or enhance long term site productivity.
The economics of forestry has always fascinated me as one of the most brain-taxing cases in economics. As an investment forestry is different from many other projects as it has unusually long gestation periods. For example, in the United Kingdom it takes over 40 years to grow coniferous and over 100 years for deciduous timber. These long gestation periods make it very clear how import ant are the magnitude of the discount rate and the method of discounting in the evaluation of investment projects. Any errors in these will misguide investors in forestry one way or the other. In addition, forestry redistributes income between gener ations. Its long gestation periods make it obvious that more than one generation will be involved in any venture. When we plant trees we know that the bulk of the benefits will be captured by future generations. Conversely, when we fell trees we reap the benefit of projects which were established in the past, mostly by generations who are long gone. So far most economists have devoted their time and energy to analysing income distribution in an intragenerational context, and this is a very sensitive and controversial issue. After all, most revolutions have taken place because of the uneven income distribution which was oppressive for the majority. Forestry helps us to study the case from the viewpoint of different generations. Forestry necessitates estimating timber prices a long time ahead.
Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.
It has been increasingly recognized that trees and vegetation in urban areas provide a number of ecological services beyond beautifying cities. The purpose of urban forestry is to use trees and natural habitat patches to ameliorate negative environmental impacts of cities and to contribute to the creation of more livable, ecological sustainable 'co-cities'. Ecology, Planning, and Management of Urban Forests takes an international approach to sharing knowledge about the management of urban forests that has been learned through studies in many different regions. This allows the reader to evaluate methods and management that are appropriate for particular geographic, environmental and socio-political contexts. Urban forests are also approached on regional and landscape scales to encompass more natural environments in and around cities, rather than within arbitrary municipal boundaries.
