In ogni foresta e stata costituita un area di studio permanente di dimensioni variabili fra 0,16 and 1 ha and si and proceduto al censimento della componente arborea viva and al rilievo dei parametri dendrometrici secondo un protocollo unico as discussed by the authors.Abstract:
Lo scopo del lavoro e quello di fornire risultati preliminari su alcune caratteristiche strutturali di boschi appenninici che per la loro complessita strutturale potrebbero essere considerati come esempi di foreste vetuste o potenzialmente tali nella Eco-Regione Mediterranea. Ad oggi per questa Regione i dati di riferimento disponibili sono relativamente scarsi e la definizione di parametri indicatori di vetusta e complicata dalla forte e prolungata, fin da tempi remoti, azione di disturbo da parte dell’uomo. Il presente studio ha preso in considerazione 10 foreste appenniniche, da tempo sottoposte a vincoli di protezione, nelle quali si osservano significative differenze rispetto a popolamenti attivamente gestiti dal punto di vista selvicolturale. In ogni foresta e stata costituita un’area di studio permanente di dimensioni variabili fra 0,16 e 1 ha e si e proceduto al censimento della componente arborea viva e al rilievo dei parametri dendrometrici secondo un protocollo unico. Le caratteristiche dimensionali e strutturali hanno mostrato un’ampia variabilita fra le aree considerate.read more

Living and Dead Aboveground Biomass in Mediterranean Forests: Evidence of Old-Growth Traits in a Quercus pubescens Willd. s.l. Stand
Emilio Badalamenti,Tommaso La Mantia,Giovanni La Mantia,Antonino Cairone,Donato Salvatore La Mela Veca +4 more
TL;DR: As the investigated forest showed some typical old-growth traits, it deserves to be fully protected and could be a permanent monitoring area for studying deadwood and stand dynamics in mature Mediterranean stands.

Does a set-aside conservation strategy help the restoration of old-growth forest attributes and recolonization by saproxylic beetles?
Christophe Bouget,Guillem Parmain,Olivier Gilg,Thierry Noblecourt,Benoit Nusillard,Yoan Paillet,Coryse Pernot,Laurent Larrieu,Frédéric Gosselin +8 more
TL;DR: This study compared structural stand features and saproxylic beetle assemblages in two stand classes – recently harvested stands and long-established reserves, where less or more than 30 years had elapsed since last harvest to argue in favor of permanent strict fixed-location reserves.

Stand structure and plant species diversity in managed and abandoned silver fir mature woodlands
TL;DR: In this article, the authors investigated the use of mixed models to compare deadwood and plant diversity between matched managed and unmanaged pairs of forests, with the hypothesis that their differences were due to direct effect of abandonment.

The influence of forest management on beech (Fagus sylvatica L.) stand structure and genetic diversity
Donatella Paffetti,Davide Travaglini,A. Buonamici,Susanna Nocentini,Giovanni G. Vendramin,Raffaello Giannini,Cristina Vettori +6 more
TL;DR: The old growth forest had a higher spatial structuring of genetic diversity than did the managed stand, and rare markers were lost.

Forest dynamics and disturbance regimes in the Italian Apennines
TL;DR: In this article, the authors introduce the setting under the geological and climatological point of view and review the literature on the interactions between these long-term drivers and the specific, structural, and genetic diversity of these forest communities (e.g., effects of glacial refugia or tectonic/volcanic activity), followed by a brief outline of what little is known about natural disturbance regimes and their range of variability.

Old-growth forests as global carbon sinks.
Sebastiaan Luyssaert,Ernst Detlef Schulze,Annett Börner,Alexander Knohl,Dominik Hessenmöller,Beverly E. Law,Philippe Ciais,John Grace +7 more
TL;DR: The results demonstrate that old-growth forests can continue to accumulate carbon, contrary to the long-standing view that they are carbon neutral, and suggest that 15 per cent of the global forest area, which is currently not considered when offsetting increasing atmospheric carbon dioxide concentrations, provides at least 10 per cent the global net ecosystem productivity.

Coarse woody debris and stand characteristics in mature managed and old-growth boreal mesic forests in southern Finland
TL;DR: It is suggested that the most efficient short-term management strategy to increase structural diversity and old-growth attributes in managed forests would be to apply harvesting methods retaining the old- growth characteristics that already exist in overmature and mature stands.

TL;DR: In this paper, the volume of dead wood in 86 beech forest reserves, covering most of the range of European beech forests, was analyzed and the mean volume was 130 m 3 /ha and the variation among reserves was high, ranging from almost nil to 550 m 3/ha.

Regeneration patterns after intermediate wind disturbance in an old-growth Fagus-Abies forest in southeastern Slovenia
TL;DR: In this article, the authors studied patterns of tree regeneration in relation to canopy structure in a 1ha plot damaged by an intermediate windstorm in 1983 and a 1-ha control plot regulated by small-scale canopy gaps in an old-growth Fagus sylvatica -Abies alba forest, southeastern Slovenia.
