“…Man et al (2013) also reported that reduced harvest levels stored significantly more carbon over the 100-year planning horizon as compared to strategies that focused on tree growth rates (Johnson et al 2009). Similar conclusions have also been drawn from boreal forests (Garcia-Gonzalo et al 2007, Man et al 2013, Europe (Fortin et al 2012), and Chile (Swanson 2009), Australia (Ranatunga et al 2008), and other regions.…”

“…A particular challenge, in this regard, is to seek site-specific management options because of the variations among ecosystem types and between the regions and their importance at different temporal scales (e.g., short-term vs. longterm values - Lafortezza et al 2008). Stimulated by these needs, numerous large-scale experiments in the United States (Chen et al 2014) and elsewhere (Garcia-Gonzalo et al 2007, Ranatunga et al 2008, Fortin et al 2012, Man et al 2013) were initiated to manipulate ecosystem structures and compositions. These experiments, unlike conventional approaches in forestry and ecology (Sheriff & He 1997), were designed to mimic natural and human disturbances at large spatial scales and to quantify the ecological responses with sound controls of the manipulations and statistical confidence (i.e., random block design with at least three replications).…”

, ranging from 1.60 to 1.94 Mg ha -1 yr -1 at the NHM plots. Changes in the net AGB growth rate were contributed by different growth rates of live trees and mortality and exhibited clear intra-annual variation during the five sampling periods. We observed a decreasing contribution of Quercus velutina (black oak) AGB (~6%), an increasing trend for Q. alba (white oak), and a stable change for Q. coccinea (scarlet oak) during the study period.

“…Gap models that incorporate management options, e.g. LINKAGES, have been compared to inventory data from four Eucalyptus-dominated plots over a time period of 40 years in terms of biomass and basal area (Ranatunga et al 2008); Seidl et al (2005) used data from two long-term observation sites in Austria to compare simulated and observed growing stock and diameter distribution over a time span of 20 years; and Lasch et al (2005) employed data from one Pinus sylvestris L. stand in Brandenburg (Germany) to evaluate model performance with regard to various measured properties over 61 years.…”

Summary1. The empirical study of forest ecosystem dynamics is difficult because of the longevity of trees. Many types of models were developed to assist with this problem, all of them with advantages and disadvantages. The strengths of gap models are that they are able to simulate forest dynamics under changing climatic conditions and are therefore suitable for exploring future forest dynamics. 2. Most temperate and boreal forests are managed, making it important to incorporate harvesting functions depicting a wide range of silvicultural practices into the models and to test them under different climatic conditions. This is a necessary prerequisite to the application of these models under climatic change scenarios. Most gap models, however, do not feature such submodels, which disqualifies them as decision support tools. 3. We implemented a management submodel in the gap model ForClim that is able to simulate a wide range of cutting and thinning techniques, including continuous cover forestry ('plentering'). We tested the new submodel against long-term data (72-111 years) from eight growth and yield research plots across climatic conditions ranging from warm-dry to cold-wet. 4. Stem numbers were simulated accurately in nearly all cases, basal area showed a good fit on Quercus-dominated plots, but an over ⁄ underestimation on Fagus sylvatica-dominated and Picea abies-dominated plots. The diameter distributions simulated for the time of the most recent inventory did not differ significantly from empirical data except for two cases. Harvested basal area and stem numbers mostly agreed well with empirical data, but showed the same deviation from reality as simulated basal area. 5. Simulations run with an accurate management plan taken from foresters' reports for the plots yielded nearly the same results as those run with a generic management setting. 6. Synthesis and applications. We have demonstrated that (i) the management submodel adequately depicts silvicultural treatments, including continuous cover forestry; (ii) a generic harvesting setting can be substituted for a very detailed one, thus eliminating a major source of uncertainty in assessments of future forest dynamics; and (iii) as the new version of ForClim is able to deal with widely differing current climates, it can be employed with reasonable confidence to simulate future management strategies under climatic change. Overall, this modelling work is a major step towards the use of succession models as decision support tools in forest management.
