Relative to the arrangement of forest ecosystems we focused on stand diversity within particular PRP.…”

“…Zdeněk Vacek, e-mail: vacekz@fld.czu.cz et al 2013) and assumed impacts of climate change still enhance the need of forest stand transformation (Steffen et al 2007;Zalasiewicz et al 2010;Kulla & Sitková 2012). Transformations become part of a broader strategy of climate change mitigation, and other urgent environmental problems of this time such as loss of biological diversity (Thomas et al 2014;Spiecker et al 2004). One of the crucial factors influencing the success of performed forest transformations is the existence of natural regeneration that is more productive and resistant to external environmental impacts in comparison with artificial regeneration (Hasanov et al 2016).…”

“…Mostly, reasons for forest transformation failure are genetically inconvenient reproductive material not sufficiently adapted to conditions of the given environment and unsuitable silvicultural methods and techniques (Godefroid et al 2011;Wenying et al 2013). The reproductive material is very important for transformation because it influences transformation success from both short-term and long-term aspects (Thomas et al 2014). Genetic suitability positively influences not only individual tree populations (Breed et al 2012) but also the general ecosystem function and resistance (Thompson et al 2010;Kettenring et al 2014).…”

The paper deals with development of the natural regeneration of even-aged spruce-beech forests during their transformation to uneven-aged stands with diversified structure at the Jedlový důl area in the Protected Landscape Area Jizerské hory Mts., Czech Republic. Shelterwood management system and free felling policy based on selection principles has been applied there since 1979 with the support of admixed tree species of the natural species composition, especially silver fir (Abies alba Mill.). The research was focuses on structure and development of natural regeneration with the emphasis on ungulate damage and interaction with tree layer from 1979 to 2015. In the course of 36 years, the regeneration structure was diversified towards the close-to-nature tree species composition, spatial and age structure. The number of regeneration recruits increased in average from 941 to 41,669 ind ha -1. During this period share of European beech (Fagus sylvatica L.) significantly (p < 0.01) increased (by 53.6%), while the share of Norway spruce (Picea abies [L.] Karst.) decreased (by 51.5%), such as damage caused by ungulate (by 61.4%) with the highest loses on sycamore maple (Acer pseudoplatanus L.), rowan (Sorbus aucuparia L.) and silver fir. Moreover, the parent trees had a significant negative influence on natural regeneration at smaller spacing (within a 1 -5 m radius from the stem). Both, regeneration potential and effective role of the tree layer during the forest transformation has been confirmed as important prerequisites for ongoing forest transformation.

“…De esta forma, se estarían restaurando sistemas complejos y fomentando la provisión de servicios ecosistémicos a distintas escalas (local a global), lo que es esencial para la adaptación al cambio climático (Harris et al 2006). Para lograr esta adaptación es indispensable considerar también aspectos genéticos, lo que de no ser considerado frecuentemente es causa de fracasos en la restauración (Thomas et al 2014). Por este motivo, Thomas et al (2014) recomiendan a) colectar y propagar germoplasma de tal forma de asegurar una base genética amplia de poblaciones, b) hacer coincidir para un sitio, especies y procedencias con base en condiciones de sitio actuales y futuras, rangos de variación y fuentes de semilla, y c) planificar la restauración a nivel de paisaje para favorecer conectividad e integración entre fragmentos.…”

En definitiva, la silvicultura como eje central del manejo forestal sustentable, está llamada a ser prota-gonista en este nuevo paradigma, como herramienta que incrementa la efectividad de las técnicas de restauración, mezclando técnicas pasivas y activas a nivel de paisaje, y operacionalizando iniciativas de restauración en bosques nativos (Bannister 2015), en forma diferenciada de acuerdo al tipo de bosque a restaurar (figura 2) y las metas o alcances de dicho proceso (figura 1).…”

SUMMARYWhen we apply silviculture in the context of forest restoration, we aim at increasing the biodiversity and structural complexity of degraded and fire-disturbed old-growth forests, secondary forests (degraded and with normal density) and exotic monocultures, in order to improve their ecological functionality and maximize the ecosystem services that they provide. This work aims at: a) providing a conceptual framework on the terminology related to forest restoration; b) highlighting the importance of silviculture as a tool for the restoration of forests; and c) recommending some basic questions that help professionals and technicians linked to forest restoration, to dimension the required efforts to apply restoration. Forest restoration in Chile should be based on a pragmatic and functional paradigm that includes a wide range of options or strategies dealing with transformed or degraded forest ecosystems, including ecological restoration, rehabilitation, reconstruction, replacement and conversion. Depending on the initial state in which the ecosystem is and the target state, some of these options will lead the ecosystem back to its historical state and others only will seek to restore some attributes. In this context, silviculture is the key to enrich the concepts of forest restoration, translating these into strategies, techniques and real practical solutions.Key words: structural attributes, degraded forests, Chile, structural complexity, forest management. RESUMENEn el contexto de la restauración de bosques, la silvicultura tiene como propósito primordial aumentar el nivel de biodiversidad y complejidad estructural en bosques adultos degradados, en bosques secundarios (de densidad normal y degradados), en bosques quemados y en plantaciones, para mejorar su funcionalidad ecológica y, en consecuencia, incrementar los potenciales bienes y servicios ecosistémicos desde estos bosques. Este trabajo tiene por objetivo: a) proporcionar un marco conceptual sobre la terminología relacionada con la restauración de bosques; b) resaltar la importancia de la silvicultura como herramienta para la restauración de bosques templados; y c) recomendar algunas preguntas básicas que ayuden a profesionales y técnicos a dimensionar adecuadamente los esfuerzos requeridos para la restauración. La restauración de bosques en Chile debiera estar basada en un paradigma pragmático y funcional que incluya un amplio rango de opciones o estrategias que tratan con bosques transformados o degradados, tales como restauración ecológica, rehabilitación, reconstrucción, reemplazo y conversión. Algunas de estas opciones llevarán al ecosistema de vuelta a su trayectoria histórica y otras solamente buscarán restaurar algunos atributos, lo que dependerá del estado inicial en el que se encuentra el ecosistema y la meta u objetivo planificado. En este contexto, la silvicultura es clave para enriquecer los conceptos de la restauración de bosques, traduciendo estos en estrategias, técnicas y soluciones prácticas reales.Palabras clave: atributos estruct...
