Practising sustainable forestry means managing our forests in a way that meets our needs at present but that does not compromise the ability of future generations to meet their needs. They will rightly expect that their forests and woodlands offer at least the same benefits and opportunities as we enjoy today. To sustain these expectations, […]
Pests and diseases can be carried on plants and trees, seeds, wood and wood products including wooden packaging material and isolated bark. They may also be carried on vehicles and machinery where they have not been properly cleaned and are carrying soil or plant debris. If you intend to export such material out of Great […]
Horse chestnut is an important amenity tree species which has been significantly affected over the past decade by a widespread outbreak of bleeding canker disease. Symptoms include rust-coloured or blackened bleeding cankers on the stem and branches, which can lead to tree mortality. The causal agent of this disease is the pathogenic bacterium Pseudomonas syringae […]
Forests and forest management practices can affect surface water acidification in a number of ways. The primary mechanism is the ability of tree canopies to capture more sulphur and nitrogen pollutants from the atmosphere than other types of vegetation. Pollutant scavenging is expected to have peaked in the 1970s when emissions were greatest and led […]
Direct seeding can be a useful method for creating new woodland on former agricultural sites. However, the success of the technique is variable when it is used to restore conifer plantation sites to native species. Seed predation by small mammals, particularly the wood mouse, has been identified as a factor potentially limiting success. Small mammals […]
The management of forests and woodlands requires an effective road network to provide access for the machinery required to plant and harvest trees and extract timber and wood products. Roads are also used by visitors for access and activities such as cycling and mountain biking. Forest roads and bridges must be constructed so that they […]
Forests and woodlands represent a substantial stock of carbon that is contained in soil, trees and other vegetation. They are a key component of the global carbon cycle and their effective management, at both global and regional scales, is an important mechanism for reducing greenhouse gases in the atmosphere. Understanding what determines the size of […]
Deadwood is a vital component of a properly functioning forest ecosystem. It plays an important role in sustaining biodiversity and in delivering ecosystem services such as soil formation and nutrient cycling. In the UK up to a fifth of woodland species depend on dead or dying trees for all or part of their life cycle […]
The removal of tree stumps and coarse roots from felling sites as a source of woody biomass for bioenergy generation is well established in parts of Europe, and interest has been expressed in replicating this practice in some regions of the UK. Overseas research shows that stump harvesting can pose a risk to sustainable forest […]
The Environmental Change Network (ECN) was established in 1992 to provide a framework for monitoring the effects of a range of environmental drivers on freshwater and terrestrial ecosystems. The Alice Holt ECN site represents the Forestry Commission’s commitment to this long-term collaborative programme. This Research Note reviews data collected at the Alice Holt site over […]
This Technical Note provides guidance on matching harvesting systems to site conditions to reduce the risk of soil damage and water pollution. It updates some previously identified issues and describes some new techniques. Information is provided on site planning, selection of machines, brash mat construction and maintenance, forest road approaches/drainage and roadside stacking.
The aim of this Field Guide is to assist forestry practitioners in making responsible management decisions by providing them with a way to identify soil quickly. This is done via a series of keys aimed at those with little or no experience of soil classification.
Ecological Site Classification (ESC) will help forest managers to select tree species, and to make related decisions based on an appreciation of the ecological potential of sites. The classification focuses on the key factors of site that influence tree growth, and that are important to the rest of the ecosystem. This site-orientated approach to tree […]
This Bulletin describes how foresters can use cultivation to provide a favourable site for tree survival and growth. A guiding principle is to work within the limitations of the site and to appreciate the effects of cultivation upon the microsite and the wider forest environment. The wide range of cultivation techniques now available means that […]
Describes a site classification that provides a sound ecological basis for the sustainable management of forests and resulting timber production, wildlife conservation and other benefits. Applicable to all kinds of woodlands, it incorporates the existing classification of soil types used for many years when selecting silvicultural options. Much of this publication is specific to Grampian […]
