Broadleaved trees and shrubs are frequently scarce in upland forests in Britain, and national policy is to increase the proportion of broadleaves because of their value as wildlife habitat. Birches (Betula pubescens Ehrh. and Betula pendula Roth.) are between them adapted to succeed on a wide range of soils and are the commonest native trees […]
If you have questions relating to laboratory analysis, including soil and tree samples, then please read the following frequently asked questions, which will help direct you to the relevant resource.
Milder and wetter winters, followed by increased spring rainfall, are likely to enhance the survival and infection potential of many tree pathogens. Hotter, drier summers leading to drought stress in trees will also increase their susceptibility to disease and expand the distribution range of some pathogens. The increased incidence and severity of diseases caused by Phytophthora species reduces the benefits that trees provide, including climate change mitigation.
The report of Forest Research for the year ending March 1950. The report includes:IntroductionSummary of the year’s workPart 1: Work carried out by Forestry Commission staff:Forest tree seed investigationsExperimental work in the nurseryNursery extension experiments at Radnor forestExperiments in planting on upland heathsPlantations on peatlandsDerelict woodland investigationsProvenance studiesSpacing of oak in plantationsSpacing experiments in conifersStudies […]
On moorland and heathland soils in Great Britain nitrogen deficiency can severely restrict the growth of certain conifer species, including Sitka spruce, the main commercial species. Until the 1970s this was thought to be due solely to competition from heather and was commonly known as ‘heather check’. However, increased planting of Sitka spruce on very […]
This report assesses the distribution of the Welsh peatlands, gives an overview of the likely impacts of peat forming factors and afforested peatland restoration, develops national and field based assessment schemes for the assessment of afforested peatland in Wales viable for restoration, carries out a national GIS assessment identifying potential restoration areas in Wales, tests […]
A multi-partner Europe wide transdisciplinary project to understand the large-scale diversity and distribution of ectomycorrhizal fungi across Europe, taking into account long-term monitoring of environment, climate, soil and geographical variables.
Information on how tree roots and trenching affect structures such as pavements in the urban environment, and practical considerations to greenspace development to reduce damage from tree roots
This bulletin is an account of investigations conducted during a number of years by Dr. G. K. Fraser, of the Department of Forestry, Aberdeen University, into the establishment of timber crops on peat soils in Scotland and particularly under west coast conditions as illustrated at Inverliever on Loch Awe. The investigations recorded in this bulletin […]
Landscaped sites are often seeded with vigorous varieties ot grass and legume species, which, while reducing soil erosion and giving an attractive green appearance, may kill young trees or check their growth. Weeds compete with trees for moisture, nutrients and light; but they can also interfere by releasing toxins, modifying soil and air temperatures, and […]
