| Abstract: | Ionic fluxes in a semi-mature stand of Sitka spruce (Picea sitchensis (Bong.) Carr.), on a spodosol in eastern Ireland, were monitored over an eight-year period, 1991–1998. The paper focuses on the long-term viability of forests in this region. Input-output balances, proton budgets and critical loads suggest that the long-term sustainability of forests in the region is threatened unless atmospheric emissions of anthropogenic substances can be controlled. |
