Figure 4.1 shows a forest’s contribution to the carbon cycle. Trees absorb carbon dioxide through photosynthesis and release it through respiration; the difference is new biomass. Some of this biomass is dropped to the forest floor as litter (foliage, deadwood, etc), which in due course decays and is either released...
Deadwood is a vital component of a properly functioning forest ecosystem. It plays an important role in sustaining biodiversity and in delivering ecosystem services such as soil formation and nutrient cycling. In the UK up to a fifth of woodland species depend on dead or dying trees for all or...
An evaluation of the key issues relating to woodland and the Water Framework Directive
This Practice Guide provides advice to forest managers, practitioners, planners and supervisors, on how forest operations should be planned and managed to protect the water environment.
Forests and forest management practices can affect surface water acidification in a number of ways. The primary mechanism is the ability of tree canopies to capture more sulphur and nitrogen pollutants from the atmosphere than other types of vegetation. Pollutant scavenging is expected to have peaked in the 1970s when...
Impacts of forest operations on archaeological evidence
Analysis of 22 years of water chemistry data from afforested Welsh catchments revealed trends indicative of recovery from acidification
This report assesses the distribution of Welsh peatlands and gives an overview of the likely impacts of peat forming factors and afforested peatland restoration. National and field based assessment schemes are developed for the assessment of afforested peatland in Wales viable for restoration, as well as a national GIS assessment...
Some of what we have worked on this year A major work area at Forest Research this year has been the development of tools, guidance and research into the effects and mitigation of climate change. In 2022, we published the results of our pioneering Storm Damage Assessment, which establishes the...
Environmental factors affecting incidence and distribution of AOD
Try not to sample in the rain – but if samples are wet, pack in kitchen towel All specimens: Send enough specimens to show all stages of the disorder, from apparently healthy to severely damaged tissue. Pack and send soon after collection ensuring that the specimens are not wet and that...
This Research Note summarises recent research on the carbon balances of two forest stands: an upland Sitka spruce plantation in Harwood Forest in the northeast of England, and a lowland deciduous oak plantation in Alice Holt Forest in southeast England.
