WOM21 Acid Sensitive Catchment
Forestry is known to affect the acidification of waters, principally due to the ability of forest canopies to capture more acidic sulphur and nitrogen pollutants from the atmosphere than shorter types of vegetation. As a result, it is important to manage forestry within vulnerable areas to ensure that the problem is not exacerbated and opportunities for improvement are realised.
Areas vulnerable to acidification are defined as the catchments of river and lake water bodies identified by Natural Resources Wales as the water regulatory body, as failing or at risk of failing Good Ecological Status due to acidification. Failing water bodies are those where the acidity of out-flowing waters exceeds the Water Framework Directive chemical standards for pH or Acid Neutralising Capacity.
The UKFS Practice Guide Managing forests in acid sensitive water catchments - Forest Research describes measures that can be taken to minimise adverse impacts. NRW has also published guidance on how it implements this aspect of the standards in Wales - gn001-managing-forests-in-acid-sensitive-water-catchments-in-wales.pdf (cyfoethnaturiol.cymru). New woodland creation proposals in acid sensitive areas should be considered in relation to these guides and actioned accordingly. See GN002 for more detail.
