“…To maintain healthy populations, yew trees require the reduction of canopy density and light competition [3]. Continuous selective thinning with a removal of 30% of the stocking volume was recommended to reduce the competition of beech [4,44]. Most likely due to the cuttings, the Danish population of yew increased from no more than 200 individuals in 1925 to above 2000 in 1998; regular selective cuttings of large beech trees have been applied since the area was protected in 1993 [45].…”

Abstract:The increasing probability of Taxus baccata (L.) decline given climate change brings forth many uncertainties for conservation management decisions. In this article, the authors present the effects of applying regeneration cuttings since the year 2000 on the viability of the understory yew population. By collecting data from a stand located at the centre of the largest population of European yew in Slovakia, containing approximately 160,000 individuals, and analysing tree-ring records from 38 sampled trees, the improved performance of yews, including stem growth, seed production, and number of regenerated individuals, was revealed. Thinning the canopy by removing 15% of the growing stock volume per decade, combined with the subsequent irregular shelterwood cuttings, was assessed as a useful strategy. Moreover, lower radial growth of females compared to males, but simultaneously their similar response to climate, suggests a possible trade-off between reproduction and growth. Release cuttings of up to 30% of the standing volume in the vicinity of the female trees, executed in the rainy summers following warmer winters, and consistent elimination of deer browsing, can further enhance the positive effects of applied cuts on yew viability. Overall, the suggested active measures could be considered as an effective option to preserve the unique biodiversity of calcareous beech-dominated forests in Central Europe.

“…Some studies focus on the conservation of forest species in Europe. Dhar et al (2008), prioritize six conservation strategies of a species of yew Taxus L. Bacata in Austria, using AHP to evaluate them. Romero-Calcerrada and Luque (2006) used an indicator species (Picoides trydactilus) for assessing the biodiversity of a forest of Finland, obtaining functions and habitat suitability maps of this species.…”

ABSTRACT:Multi-criteria analysis in collaborative decision making can provide a useful tool to improve the governance in protected areas with strong conflicts between stakeholders. This paper offers an in-depth review about MCDM methods in protected areas. The analysis considers the topics Land Use, Management, Species, and Zoning and it is based in two dimensions: Methods and Participation. Topics and MCDM methods and Topics and Participation were significantly related and contrasted using a Chisquared test, respectively. We have identified two groups by topics: Zoning and Species use continuous non participative methods and Land Use and Management use discrete methods with increasing participation. KEYWORDS:Collaborative Decision-Making, Multi-criteria analysis, protected areas. Una revisión crítica de la toma de decisiones multi-criterio en áreas protegidas RESUMEN:El análisis multi-criterio para toma de decisiones colaborativa ofrece una herramienta útil para mejorar la gobernanza en áreas protegidas, con fuertes conflictos de intereses entre agentes. Este artículo ofrece una revisión en profundidad sobre métodos MCDM en áreas protegidas. El análisis considera los temas Uso de la tierra, Gestión, Especies y Zonificación, y se basa en dos dimensiones: Mé-todos y Participación. Los Temas y las Técnicas MCDM y los Temas y la Participación están significativamente correlacionados respectivamente según un test Chi-cuadrado. Hemos identificado dos grupos: Especies y Zonificación usan métodos continuos no participativos y Uso de la tierra y Gestión, utilizan métodos discretos donde la participación es creciente. PALABRAS CLAVE:Análisis multi-criterio, áreas protegidas, toma de decisiones colaborativa.

“…The use of preferences expressed for a given set of C&I provide the opportunity for scenario analysis from different stakeholder perspectives (Herath 2004). In particular, such kind of scenario analysis applied is fundamental for attaining consensus and achieving technically defensible policy options (Bojórquez-Tapia et al 2005, Dhar et al 2008.…”

© iForest -Biogeosciences and Forestry Introduction Approaches in community forestry managementCommunity forestry has shifted from traditional participatory, to participatory and collaborative management approaches that integrate local and scientific knowledge (e.g., Walters 1986, Maser 1996, Schreiber et al. 2004. The involvement of stakeholders to manage the forests as community forestry has become a widely accepted participatory management philosophy, along with the sustainability concept. In this regard, the concept of sustainability has become a dominant paradigm for the management of the remaining global forests, particularly tropical forests (Khadka & Vacik 2012). The concept of criteria and indicators (C&I) has produced an increasing number of initiatives, which has contributed to the promotion and achievement of Sustainable Forest Management (SFM), such as monitoring, reporting and management instruments at a global, national and community management level. In its early phase, the International Tropical Timber Organization (ITTO) began to develop C&I sets (ITTO 1992(ITTO , 1993 and as yet, nine eco-regional forestry processes have been established (Wijewardana 2008), involving 149 countries, whose combined forest area equals 97.5 percent of the world's total forest area. Among others, the Pan-European and the Montreal processes for temperate and boreal forests, dry zone Africa process for arid zones forests, the African Timber Organization (ATO) Process; the near east process and the regional initiatives for dry forests in Asia process.The traditional meaning of sustainability in terms of sustained yield was radically expanded (Glück 1995). Sustainable forest management is defined as "stewardship and use of forests and forest land in a way, and at a rate, that maintains their biodiversity, productivity, generation capacity, vitality, and their potential to fulfill now and in the future, relevant ecological, economic, and social functions at local, national, and global levels […]" (MCPFE 1993). However, there exists a wide variety of planning and management approaches which comprise different schools of thought and allow different impacts. Therefore, in community forest management the practical implementation of the planning approaches is often highly debated and a promising approach is hardly identified. In a traditional participatory planning and management approach, goals are set and one management strategy is selected as the optimal one (Linkov et al. 2006). It has been often criticized that in such a setting process information sharing is restricted, stereotypes are reinforced, and that a limited public involvement in the plan development, as well as win-lose solutions, are generally promoted (Friedmann 1973, Susskind & Cruiskshank 1987, Blahna & Yonts'-Shepard 1989, Maser 1996, Wondolleck & Yaffee 2000. Walters (1986) introduced the concept of an evolutionary ("trial and error") approach, which is closely linked to the traditional participatory approach, but starts with a haphazard set of choices ...
