“…The studies at regional scales are not included. These include Uuttera et al (1997) from the Ladenso forest inventory area in Russian Karelia, Sirén (1955), Aaltonen 1919and Lassila (1920) in northern Finland, and Zackrisson (1977 in midnorthern Sweden. The following Russian studies also lack information on the exact location: Kazimirov (1971), Zyabchenko (1984) and Volkov (2003).…”

The aim here was to review and summarize the findings of scientific studies concerning the types of forest dynamics which occur in natural forests (i.e. forests with negligible human impact) of boreal Fennoscandia. We conducted a systematic search for relevant studies from selected reference databases, using search terms describing the location, structure and processes, and degree of naturalness of the forest. The studies resulting from these searches were supplemented with other known works that were not indexed in the databases. This procedure yielded a total of 43 studies. The studies were grouped into four types of forest dynamics according to the information presented on the characteristics of the native disturbancesuccession cycle: 1) even-aged stand dynamics driven by stand-replacing disturbances, 2) cohort dynamics driven by partial disturbances, 3) patch dynamics driven by tree mortality at intermediate scales (> 200 m 2 ) and 4) gap dynamics driven by tree mortality at fine scales (< 200 m 2 ). All four dynamic types were reported from both spruce and pine dominated forests, but their commonness differed. Gap dynamics was most commonly reported in spruce forests, and cohort dynamics in pine forests. The studies reviewed provide the best obtainable overall picture of scientific findings concerning the characteristics and variability of the unmanaged boreal forest dynamics in Fennoscandia. The results demonstrate that the unmanaged Fennoscandian forests are characterized by more diverse and complex dynamics than has traditionally been acknowledged.

“…Forest management leads to changes in horizontal and vertical structure [19,27], in dead wood [14,32] and in the species composition [26,36]. Some silvicultural practices can enhance biological diversity in managed forests, such as retaining old trees [31], maintaining adequate levels of dead wood [35], establishing mixed stands [28] or extending rotation lengths [9].…”

-The age structure of forests is one of the most important features for sustainable forest management. In this paper, an age distribution model is proposed which extends the age range in managed Pinus pinea L. forests. The method, termed extended rotation, consists of defining the theoretical global structure formed by several management circles, gradually reducing the area managed through longer rotations. The extended rotation method has been applied to obtain a target age distribution in a Pinus pinea forest. For this age distribution, the timber and pine nut (pine nut) production has been predicted for the next 40 years and compared with the most commonly applied method in Pinus pinea stands, the scattered periodic blocks management system. The application of the extended rotation method leads to a 15% timber yield loss, whereas there is a 10% pine nut production increment and the diversity of the age distribution and the basal area heterogeneity increase in the long term. rotation age / forest management / Pinus pinea / pine nut production / age structure model Résumé -Révolution étendue pour intégrer la production de bois et la production de pignes avec une conservation de la diversité structurelle dans les forêts de Pinus pinea L. La structure des âges des forêts est un des aspects les plus importants pour la gestion forestière durable. Dans cet article, un modèle de distribution par âges qui permettra d'élargir l'intervalle d'âges représenté en forêts aménagées de Pinus pinea L. est proposé. Cette méthode, dénommée « révolution étendue », est basée sur la définition de la structure théorique formée par plusieurs séries de révolutions différentes, et la réduction graduelle simultanée de la surface des séries des plus longues rotations. La méthode de révolution étendue a été appliquée sur une pinède de Pinus pinea afin d'obtenir une structure des âges de référence. Avec cette structure des âges, les productions de bois et de pignon ont été quantifiées pour les prochaines 40 années, et comparées avec la méthode du « groupe bleu ». La méthode de révolution étendue entraîne une réduction de 15 % dans la production de bois, tandis que la production de pignes augmente en 10 % et la diversité de la distribution par âge et l'hétérogénéité de la surface terrière augmentent à long terme. rotation / aménagement forestier / Pinus pinea / production de pignes / modèle de distribution par âge

“…(Tyrrell & Crow, 1994), some studies e.g. (Uuttera et al, 1997) did not suggest diameter distribution to be essentially helpful for describing forest structure, as comparing the diameter distributions from different stands bears some degree of sophistication.…”
