“…The higher iv in M than in S plots after the second thinning could be related to a fertility decrease because of nutrient loss in the highest thinning intensity. In the study site, the main nutrient limiting Scots pine growth appears to be phosphorus (Primicia et al, 2014), whose reserves are susceptible to overexploitation (Blanco et al, 2005). In this context, we suggest that the decrease in soil fertility is mainly due to a reduction in litterfall after thinning.…”

Prescriptions for forest thinning in high-productive Scots pine stands following the economic criteria and adapted to our region (exploitation cycle of 80 years, first thinning at 20-25 years, rotation length of 10 years, removal of 30% of the basal area; Río & Montero, 2001;Puertas, 2003) could indeed result in a significant net phosphorus loss in the study site at the long term (Blanco et al, 2005). Current forest thinning practices applied on surrounding similar stands should be consequently verified from an ecological perspective at the long term.…”

Aim of the study: We analysed the effects of thinning intensity and canopy type on Scots pine growth and stand dynamics in a mixed Scots pine-beech forest.Area of the study: Western Pyrenees. Material and methods:Three thinning intensities were applied in 1999 (0, 20 and 30% basal area removed) and 2009 (0, 20 and 40%) on 9 plots. Within each plot, pure pine and mixed pine-beech patches are distinguished. All pine trees were inventoried in 1999, 2009 and 2014. The effects of treatments on the tree and stand structure variables (density, basal area, stand and tree volume), on the periodic annual increment in basal area and stand and tree volume, and on mortality rates, were analysed using linear mixed effects models.Main Results: The enhancement of tree growth was mainly noticeable after the second thinning. Growth rates following thinning were similar or higher in the moderate than in the severe thinning. Periodic stand volume annual increments were higher in the thinned than in the unthinned plots, but no differences were observed between the thinned treatments. We observed an increase in the differences of the Tree volume annual increment between canopy types (mixed < pure) over time in the unthinned plots, as beech crowns developed. Research highlights: Moderate thinning is suggested as an appropriate forest practice at early pine age in these mixed forests, since it produced higher tree growth rates than the severe thinning and it counteracted the negative effect of beech on pine growth observed in the unthinned plots.

“…However, for actual forest management in Central Europe, which ensures sustainability of wood harvests, wood and nutrient exports may not be the most relevant indicators for stand-level intensity. In fact, presently, the harvest yield is generally lower than the average increment (German Federal Ministry of Food 2006; Ciais et al 2008), and soil fertility does not decrease even without fertilization on many sites if whole tree harvests are not conducted (Blanco et al 2005;Meiwes et al 2008;Saarsalmi et al 2010).…”

How to quantify forest management intensity in Central European forests

Existing approaches for the assessment of forest management intensity lack a widely accepted, purely quantitative measure for ranking a set of forest stands along a gradient of management intensity. We have developed a silvicultural management intensity indicator (SMI) which combines three main characteristics of a given stand: tree species, stand age and aboveground, living and dead wooden biomass. Data on these three factors are used as input to represent the risk of stand loss, which is a function of tree species and stand age, and stand density, which is a function of the silvicultural regime, stand age and tree species. Consequently, the indicator consists of a risk component (SMI r ) and a density component (SMI d ). We used SMI to rank traditional management of the main Central European tree species: Norway spruce (Picea abies [Karst.] L.), European beech (Fagus sylvatica L.), Scots pine (Pinus sylvestris L.), and oak (Quercus robur L. and Quercus petraea L.). By analysing SMI over their whole rotation period, we found the following ranking of management intensity: oak\beech\pine(spruce. Additionally, we quantified the SMI of actual research plots of the German Biodiversity exploratories, which represent unmanaged and managed forest stands including conifer forests cultivated outside their natural range. SMI not only successfully separate managed from unmanaged forests, but also reflected the variability of forest management and stand properties across the entire sample and within the different management groups. We suggest using SMI to quantify silvicultual management intensity of stands differing in species composition, age, silvicultural system (even-aged vs. uneven-aged), thinning grade and stages of stand conversion from one stand type into another. Using SMI may facilitate the assessment of the impact of forest management intensity on biodiversity in temperate forests.
