The soil conditions experienced by a growing tree are reproduced under controlled conditions. Fluid distributions with the tree are visualised using magnetic resonance imaging in order to identify stresses and determine if these are linked to drought cracking and shake.
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 […]
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 […]
In this Occasional paper information is given on the application of forest nursery herbicides. Much of this information is based on Forestry Commission trials. A brief description of the types of herbicide is given followed by information on the various herbicides which can be used at the different growth stages of forest nursery stock.Note: This […]
This Note provides information on: identifying whether there are deer present and of which species; deciding whether deer are causing damage; the ways in which deer problems can be prevented and knowing where to go for more advice.
How do contemporary Great British attitudes to urban trees vary between locality, individuals and communities with different socio-demographic backgrounds? Forest Research aims to investigate this through a rapid evidence review, a national questionnaire and a series of focus groups.
