“…The important message for conservation managers is that habitat management should aim at increasing or at the very least retaining the extent of old forest cover locally. This action might also satisfy the needs of other old forest species as well, since Tengmalm's owls apparently share a common environment with them (Trzcinski et al 1999;Reunanen et al 2002;Schmiegelow and Mönkkönen 2002;Jansson and Andren 2003;Suorsa et al 2005).…”

The loss and fragmentation of forest habitats have been considered to pose a worldwide threat to the viability of forest-dwelling animals, especially to species that occupy old forests. We investigated whether the annual survival of sedentary male Tengmalm's owls Aegolius funereus was associated with the cover of old coniferous forests in Finland. Survival and recapture probabilities varied annually with density changes in populations of the main prey (Microtus voles). When this variation was controlled for, and relationships between survival and proportions of the three different forest age classes (old-growth, middle-aged, and young) were modeled separately, the old-growth model was the most parsimonious. Survival increased with the cover of old forest, although the extent of old forest within owl territories was relatively small (mean approximately 12%, range 2-37%). This association, however, varied among years and appeared especially in years of increasing vole abundance. At such times, old forests may sustain high populations of bank voles Clethrionomys glareolus, shrews and small passerines. In addition, old forests may serve as refuges against large avian predator species, such as Ural owls Strix uralensis and goshawks Accipiter gentilis. Our results suggest that changes in habitat quality created by agriculture and forestry may have the potential to reduce adult survival, an essential component of fitness and population viability.

“…Nevertheless, positive effects on biodiversity have already been detected: changes in breeding bird assemblages have been recently reported for this area of the Apennines (e.g., common treecreper, Certhia familiaris; black woodpecker, Dryocopus martius - Suorsa et al 2005) and attributed to an evident increase in bark feeders directly dependent on the presence of large aging trees (Fantoni 2000, Tellini Florenzano 2004, Martini 2011.…”

© iForest -Biogeosciences and Forestry IntroductionIn the last decades forest management has shifted the focus from wood production to the provision of multiple environmental services and biodiversity conservation. Following this trend the conversion of forest plantations into naturally regenerating and more diverse and complex systems has become one of the aims of the sustainable forest management, often trying to revert a process which had instead transformed vast areas of natural forests into plantations across Europe since the XIX century (Johann 2006, Bolte et al. 2007.Silver fir (Abies alba Mill.) has frequently received attention from foresters and researchers, partly because there has been a long tradition of forest management in central and southeast Europe in areas where the natural share of fir is significant (e.g., Kramer 1992, Brändli 1996, but mainly because of fir's economic, environmental and social significance. Signs of decline in fir presence have also been investigated (e.g., Elling et al. 2009, Ficko et al. 2011). Recently, Volarik & Hedl (2013 suggested that periods of both decline and expansion have underpinned silver fir dynamics. While natural mixed beech-fir forests were largely converted to spruce plantations in central European mountains and in many Alpine areas (Johann 2007, Volarik & Hedl 2013, in the Apennine Mountains (Italy) fir -naturally present in beech dominated mixed hardwood forests -was generally disfavoured by forest exploitation and has become relatively rare (Nocentini 2009). Today silver fir is an important species of five Natura 2000 habitats in the Apennines, three being priority habitats (*): 9130: Asperulo-Fagetum beech forests; 9210*: Apennine beech forests with Taxus and Ilex; 9220*: Apennine beech forests with Abies alba and beech forests with Abies nebrodensis; 9410: Acidophilous Picea forests of the montane to alpine levels (Vaccinio-Piceetea); 9510*: Southern Apennine Abies alba.Fir had often been preserved in small areas around monasteries, such as Vallombrosa and Camaldoli (Tuscan Apennines) where fir cultivation has been documented at least from the XVI century (Senni 1955, Gabbrielli 2003. Since late XVIII century fir planting started in various forests in the Tuscan Apennines, and this trend continued until the middle of the XX century. Most fir plantations are on State property and until the 1970s they were managed following the traditional model based on area regulation methods with clear cutting and 100 year rotation age (Vazzano et al. 2011.In the 1970s and 1980s pure fir stands in the Apennines started showing symptoms which recalled fir decline and dieback observed in central Europe (Larsen 1986, Kandler & Innes 1995, raising some concern about the future of this species. Together with these symptoms, Heterobasidion annosum (later identified as H. abietinum -Niemela & Korhonen 1998) also caused some damage, consisting mainly in the death of individual or small groups of trees (Farina et al. 1990, Barzanti & Capretti 1996, Capretti 1998.At the end ...

“…In the case of our study area, ownership was indeed linked to variance in forest characteristics (DBH, basal area), after accounting for the effects of forest size per se. It is widely known that average DBH, basal area or timber volume have great significance for the occurrence of some species and patterns of interspecific relationships (Pakkala et al 2002;Suorsa et al 2005). Therefore, a forest's biodiversity could be indirectly connected to its ownership structure.…”

The effects of forest patch size and ownership structure on tree stand characteristics in a highly deforested landscape of central Poland

Forest structure is influenced by the origin, history and manner of forest management. All these aspects may affect the occurrence of many forest dwelling organisms. We investigated the simultaneous impact of forest patch size and ownership structure on selected forest characteristics in central Poland. We sampled stand composition, the DBH of particular tree species, basal area, species number and species diversity in all 32 forest patches found in a farmland-dominated area of 150 km 2 . Forest ownership status was linked to patch size: large patches were state-owned and small ones were private. Ownership status also affected the average DBH and basal area of all tree species pooled, with lower DBH and basal area found in private forests. The share of deciduous trees was negatively affected by forest size, while pine was positively affected, which could suggest that forest management and economic interests may be related to this factor. The share of non-native species was higher in state forests. Our results showed that forest patch size could be associated with its ownership status, which is commonly ignored in research on the relationship between forest size and species occurrence. Historical as well as sociological aspects related to private forests in Poland are also presented.
