In this Information Note volume gains from an old Sitka spruce tree breeding experiment are evaluated, allowing predictions to be made of the likely volume increases which could be expected from modern tested seed orchards and family mixtures.

The silvicultural characteristics of Prunus avium are described, based on a study in which over 40 stands throughout Britain were visited.

An analysis of citizen science hedgehog roadkill data has revealed why, when and where vehicle-hedgehog collisions are most likely to occur. The approach involved a multi-scale habitat suitability model. Suburban areas with mixtures of urban and grassland were found to be roadkill hotspots.

This paper consists of two main parts. The larger part is concerned with new models of wood product demand that have been developed at the Forestry Commission. The rest of the paper then takes these models and, comparing them with future forecasts of UK roundwood production, examines the likely future...

The research described in this Bulletin integrates the main environmental factors influencing the growth of Sitka spruce at high elevations in order to estimate future yield class.

This Bulletin provides the information for specifiers and users to make maximum use of the increasing British resource of softwoods. Its main purpose is to establish the link between requirements for current and potential end-uses and the properties and performance of these commercially important timbers. A guide to the properties...

The aim of this part of the report is to interpret, as far as possible, the results of the 1987 survey of forest health (Bulletin 74) by attempting to establish the cause(s) of the low crown densities and the crown discoloration observed in five of our most important tree species:...

This Bulletin reports on coppice growth and yield in relation to site and various stand characteristics and shows how volume or weight per hectare may be predicted from very simple measurements.

The production and use of tubed conifer seedlings in Britain have been studied between 1968 and 1973 in an extensive research and development programme based initially on Canadian practice. Results from the many nursery and forest experiments are described and form the basis for practical recommendations (see Chapter 6) on...

This publication is a revision of Bulletin 3, ‘Rate of Growth of Conifers in the British Isles’. In this revised work the original tables for European larch, Scots pine and Norway spruce have been retained unaltered, while complete yield tables for Douglas fir and Corsican pine have been added. Further,...

A survey for the collection of statistics as to the rate of growth and production of timber was begun in the summer of 1917, at a time when the large demands for timber required for military purposes and the mining industry were being met mainly from British woods. Extensive fellings...
