Plant Health controls apply to a wide range of wood products, including woodchip. These controls are in place to prevent the spread of pests and pathogens that would be ecologically and economically damaging if introduced to Great Britain (GB). Import regulations are tree species specific, and may vary according to...

This revised Guide sets out the obligations which apply to port authorities and others responsible for the points of entry in Great Britain where controlled wood, wood products or other goods which are accompanied by wooden packaging are landed. The Guide gives advice on the facilities needed, not only to...

This Field Guide provides guidance on the control of volume to be removed when marking a thinning and a guide to thinning yields. There are four sections: the first describes the yield class system and how yield class is assessed in a stand. The second covers thinning practice, including the...

Quantification of volume and wood properties affecting timber production in four minor species in GB.

Shake (internal splitting of the wood in a growing tree) is believed to affect and devalue around one-fifth of British oak crops. There is currently no fully reliable method to identify the defect in standing trees, or to predict vulnerable sites and stands without local knowledge and historical data. Shake...

The Picts: a learning resource for teachers of Curriculum for Excellence Level 2.

How effective is imbibition-drying- separation? European silver fir (Abies alba Mill.) produces good seed crops every three to five years, but these crops often have a high proportion of empty seeds. In many tree species, the empty and insect-infested seeds are removed during processing and cleaning of seed lots. However,...

The ability to accurately identify tree and shrub seedlings is invaluable to anyone with an interest in forests and woodlands and it is fundamental to practical woodland management. However, identifying seedlings in their first year of growth is not as straightforward as identifying adult trees and shrubs, as they are...

A review of known and suspected factors affecting the development of shake defects in native oaks. Produce guidance for growers and policymakers to enable an understanding of why the defect occurs, how to minimise risks in current stands, and how to avoid higher risk sites for new planting.
