The influence of forestry on acidification and recovery: Insights from long-term hydrochemical and invertebrate data

Important questions remain as to the most appropriate way to assess biological recovery given the complicated chemical and biological interactions, the often non-linear nature of change, the potential for chemical and biological hysteresis associated with acidification and recovery, and ongoing debates over recovery endpoints. Consequently, the definition of appropriate recovery endpoints required for the management of landuse and freshwaters remains a significant challenge.
