“…On the contrary, hollow trees have for a long time been known among Swedish foresters and biologists as very important for cavity nesting birds and many saproxylic invertebrates (Ehnström and Waldén, 1986;Nilsson and Baranowski, 1994;Ranius and Jansson, 2000). For Turkish conditions, similar results have been found in recent studies (Jansson and Coskun, 2008;Sama et al, 2011;Bergner et al, 2016), but this knowledge is still new and not commonly acknowledged in Turkish society.…”

This paper presents a comparative analysis of expert opinions on forest biodiversity indicators for protected areas, using a questionnaire given to forest experts in Turkey and Sweden. Experts were selected according to whether they had studied or worked in areas related to biodiversity, protected areas and sustainable forest management. A Mann-Whitney U test was used to determine the differences between the opinions of Swedish and Turkish experts regarding the indicators. The experts from both countries considered "endemic species" and "naturalness" as the most important indicators, while "overused species", "forest distribution and regeneration", "carrying capacity in terms of important species of area" and "the existence of different conservation status of protected areas" were considered equally as the least important indicators. The most important difference between the two groups was related to the indicators "dead wood" and "hollow trees", which Swedish experts found more important than their Turkish counterparts. Two other large differences were that the Swedish experts found "litter layer" much more important and Turkish experts instead found "plant species composition" much more important. The differences between the two groups reveal different perspectives regarding the planning and management of protected areas in each respective country.

“…PCA 1 represent forest as a positive factor and crop/urban as a negative factor, and PCA 2 represents crop/urban and semi-natural as explanatory variables different processes of radical transformation of landscapes. First, the Turkish cultural oak woodlands landscape (e.g., Quercus ithaburensis) of key importance for conservation of species dependent on old trees and a European biodiversity hotspot (e.g., Bergner et al 2016) is currently being logged and transformed to production-oriented conifer plantations focusing on Cedrus lebani. Second, in the Scottish hotspot landscape there is an inverse transformation process in which production-oriented conifer plantations (Picea sitchensis) (Mather 2004) are being removed, and regeneration of oak woodlands is enhanced by planting and fencing (see Online Appendix).…”

Context Maintaining functional green infrastructures (GIs) require evidence-based knowledge about historic and current states and trends of representative land cover types. Objectives We address: (1) the long-term loss and transformation of potential natural forest vegetation; (2) the effects of site productivity on permanent forest loss and emergence of traditional cultural landscapes; (3) the current management intensity; and (4) the social-ecological contexts conducive to GI maintenance . Methods We selected 16 case study regions, each with a local hotspot landscape, ranging from intact forest landscapes, via contiguous and fragmented forest covers, to severe forest loss. Quantitative open access data were used to estimate (i) the historic change and (ii) transformation of land covers, and (iii) compare the forest canopy loss from 2000 to 2018. Qualitative narratives about each hotspot landscape were analysed for similarities (iv). Results While the potential natural forest vegetation cover in the 16 case study regions had a mean of 86%, historically it has been reduced to 34%. Higher site productivity coincided with transformation to non-forest land covers. The mean annual forest canopy loss for 2000–2018 ranged from 0.01 to 1.08%. The 16 case studies represented five distinct social-ecological contexts (1) radical transformation of landscapes, (2) abuse of protected area concepts, (3) ancient cultural landscapes (4) multi-functional forests, and (5) intensive even-aged forest management, of which 1 and 4 was most common. Conclusions GIs encompass both forest naturalness and traditional cultural landscapes. Our review of Pan-European regions and landscapes revealed similarities in seemingly different contexts, which can support knowledge production and learning about how to sustain GIs.

“…Old trees can serve birds from small-sized ones like tits and nuthatch to large ones like owls. Recent studies of birds in oak forests in Turkey showed a higher number of secondary cavity nesters in older forest stands in comparison with young (Bergner et al, 2015) and woodpeckers prefer foraging and nesting in larger oaks with deeper bark furrows and a higher amount of dead wood (Bergner et al, 2016). Some of the insect species in the cavities also gain from the bird activities like different materials left by the birds.…”
