The radial growth of altogether 105 trees of spruce, pine, birch, aspen, black alder and rowan, growing in an area subsided due to mining activities in northeast Estonia, was measured. The tree-ring series were cross-dated and averaged according to tree species, and a possible influence of the surface deformation on tree growth was looked for. For the same reason, the annual basal area increment was calculated. It appeared that the subsiding event in 1998 has mostly resulted in an increase rather than a decrease of tree growth.

Key words: Tree-ring width, basal area increment, surface subsidence, mining, NE Estonia
