This Technical Note provides updated information on methods of grey squirrel control.

Stem straightness is important in determining tree and log value. The ability to make an effective assessment before harvesting is useful for forest managers and practitioners to improve forecasting, planning, marketing and resource use. This Technical Note describes three methods for assessing stem straightness in standing trees: visual assessment, photogrammetric...

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...

Collisions with fences can be a significant source of mortality for woodland birds such as capercaillie and black grouse. The construction of new fencing to protect woodland and trees in habitats supporting these two grouse species should be minimised, and the fences removed as soon as management objectives have been...

The demands for sustainably produced wood as a raw material for a variety of end uses is placing increased pressure on the forest resource in the UK. Knowledge of the timber properties of trees and logs is important to ensure that harvested wood is directed to its most appropriate end...

This Technical Note sets out the procedures for cleaning pesticide applicators and proposes a cleaning regime drawn from current sources of best practice.

Colourants used as dye markers may allow the better targeting of pesticide sprays, and could help to protect operators, as well as reducing overall levels of pesticide use in forestry.

This Technical Note provides guidance on the selection of appropriate spray nozzle(s) for use in the application of pesticides. Influences on selection, such as type of target, weather conditions, pesticide formulation, spray equipment and spray quality, are described.
