    2018 – Carbon cycle

    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 back to the atmosphere or […]

    Managing deadwood in forests and woodlands

    Lead Author: Jonathan W Humphrey
    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 part of their life cycle […]

    Advice on how to take and package samples

    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 no moisture has been added.  Despatch […]

    A Strategic Assessment of the Afforested Peat Resource in Wales

    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 identifying potential restoration areas in Wales. Field-based assessment are testing by ground truthing a number of sites in Wales and relative costs of afforested peat restoration are provided.
