In Britain, the sweet chestnut, Castanea sativa, is at the northern limit of its distribution, and as a forest tree it is of importance in the southern half of England only. So far, in Britain, it has not been seriously affected by disease, however, it is a serious matter that Chestnut Blight, which has ravaged […]
This Bulletin provides an update to the original bulletin from 1937. Spring frosts add considerably to the difficulties of establishing young plantations. Investigations which the Imperial Forestry Institute had been carrying out for the Forestry Commission since 1929 were already yielding interesting results when the great May frosts of 1935 occurred.
Part 1 of this Bulletin to brings together all the manuscripts dealing with studies on the biology and forest relations of the pine shoot moth, Evetria buoliana Schiff. Further data have been collected on the distribution of the moth in East Anglia and on the results of recent experimental control studies, which are given in […]
This bulletin contains an account of investigations on the roots of young trees carried out over a series of years for the Forestry Commission by Dr. E. V. Laing of the Department of Forestry, Aberdeen University. Special attention has been paid to the association of fungi (mycorrhiza) with roots and to the development and action […]
This Bulletin discusses the importance of nursery practice and the current methods employed. Only coniferous species are dealt with; broadleaved trees occupy a relatively small area in the new plantations. The bulletin shows that important improvements can be obtained by attention to tilth conditions (largely governed by the time of sowing), by treatment of the […]
This Bulletin discusses beetles which attack timber. They belong to various families of the order Coleoptera of which four groups may be recognised – longicom beetles (Cerambycidae), pin-hole borers (Scolytidae and Platypodidae), powder-post beetles (Bostrychidae and Lyctidae) and furniture beetles (Anobiidae). The objective of this bulletin is to describe the insects and the damage done […]
This Bulletin deals with bark-beetles, a group of insects which is closely connected with forestry practice. It is the outcome of several years’ work and of first-hand study of the beetles both in the laboratory and in the field. The purpose of the Bulletin is to give an account of those bark-beetles which occur in […]
This Bulletin provides information on the life-cycle of the silver fir chermes in Britain, as well as information on the relationship between the insect and its host tree, the silver fir, to ascertain how far the chermes was responsible for the death of the tree. The Bulletin also presents certain information collected by the author […]
The fungus phomopsis pseudotsugce, which has from time to time been known under different names, has a wide distribution in Britain and also occurs on the continent of Europe. It may attack both the green and the blue Douglas firs, the European and Japanese larches and abies grandis among the silver firs. It is possible […]
This bulletin embodies the results of an investigation into the life history of Chermes (Gillettea) cooleyi Gillette, an American species of the family Chermesidae, which has made its appearance upon the Douglas fir in this country. The insect Chermes cooleyi lives partly on the Douglas fir and partly on the Sitka spruce. It is not […]
A survey was started in May 1919, by the Interim Forest Authority, to ascertain the forest insect conditions in the British Isles, with special reference to felled areas and recently formed plantations. The main object of the survey was to determine the location, extent, and nature of the chief forest insect outbreaks and to decide […]
