TL;DR: In this paper, the authors present the implementation of stem volume harmonization by European NFIs, to obtain comparable growing stocks according to five reference definitions, and to compare the different results.
Initial effects of restoring natural forest structures in Estonia
TL;DR: In this article, the authors provide an early evaluation of the effectiveness of different restoration treatments to rehabilitate managed stands in order to increase their naturalness, including gap creation with and without added deadwood, adding deadwood without gaps, gaps plus overburning, and controls.
