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 type, intensity and cycle of […]
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 may appear on any site, […]
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, this is only possible if filled […]

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 often strikingly different in appearance.
A review of known and suspected factors affecting the development of shake defects in native oaks. Produce guidance for growers and policy makers 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.
The Native Woodland Survey of Scotland (NWSS), carried out between 2006 and 2013 has provided the first authoritative picture of Scotland’s native woodlands. It used field survey to identify the location, type, extent, composition and condition of all native and nearly native woods, as well as woods planted on ancient woodland sites (PAWS).
