“…This means that in a network of forest patches inside an open land matrix, Hazel Grouse can move over much longer distances than had been detected in agricultural landscapes, but not as far as in continuous forests (Å berg et al 1995, 1996Montadert and Leonard 2006). This observation fits the hypothesis that dispersal is not only a reflection of the physical ability of a species to move, but is also strongly influenced by a species' behavioural response to an apparently hostile habitat (Opdam et al 1984;Dunning et al 1992;Taylor et al 1993).…”

Forest fragmentation has led to a decline in the population of many forest specialists, especially those with limited dispersal abilities. However, some of these species also occur in fragmented forests, and their response to fragmentation is crucial to understand the impact of this process in maintaining forest biodiversity. The objective of this study was to investigate the effects of habitat quality, quantity and configuration on the occurrence of Hazel Grouse as the model species. Studies were performed in the Carpathian Foothills (900 km 2 , 15 % forested). Between 2000 and 2010, Hazel Grouse were detected in 25 out of 53 forest patches with high repeatability over time. Among the indices of habitat quality, the most important factors were the presence of bilberries, clearings and pioneer trees. Greater number and length of valleys also had a positive effect on the occurrence of grouse. All habitat quantity and landscape configuration variables influenced the presence of grouse positively (related to forest connectivity) or negatively (related to forest isolation). Among the explanatory variables considered, habitat quantity and landscape variables were much more important in explaining the occurrence of Hazel Grouse than variables related to habitat quality. The study shows that habitat acreage and its connectivity are crucial for the conservation and management of Hazel Grouse populations in fragmented landscapes, and therefore, it is necessary to sustain wooded corridors between larger forest patches.

Linkages in the Landscape IUCN'S FOREST CONSERVATION PROGRAMMEIUCN's Forest Conservation Programme coordinates and supports the activities of the IUCN Secretariat and members working with forest ecosystems. The goal of forest conservation is achieved through promoting protection, restoration and sustainable use of forest resources, so that forests provide the full potential range of goods and services.The programme makes contributions to policy at various levels and uses field projects to derive lessons to feed into the policy debate. The principles of Caring for the Earth, published jointly by IUCN, WWF and UNEP in 1991, are applied to these projects, which combine the needs of conservation and those of local communities. One major activity is to develop coherent and informed policies on forest conservation in order to advocate the translation of policies into effective actions. IUCN frequently advises major development institutions on forest issues, to ensure that conservation priorities are adequately addressed in their projects and programmes. The Forest Conservation Programme receives generous financial support from the Government of the Netherlands.

“…The plateau has an elongated shape in the north-south direction (46 This culturally transformed habitat type is well represented in this area of Romania, being created in the Middle Ages by the local community in order to increase acorn production and provide sheltered grazing sites for cattle. The size of this wood-pasture is large when compared to other similar habitats studied in Europe, the areas of which average 50 ha (Opdam et al 1984;Bellamy et al 1996;Hansson 1997;Goldberg et al 2007). The thinning of the original forest has led to changes in the humidity regime of the plateau, favouring the penetration of mesophilous meadows with meadow foxtail Alopecurus pratensis and great burnet Sanguisorba officinalis.…”

Ancient oak wood-pasture as a habitat for the endangered tree pipit Anthus trivialis

2009

Ancient wood-pastures are facing a major decline in several European countries. These habitats are of great importance for biodiversity because of their special semi-natural character that increases landscape variability and connectivity. In this paper we examine the habitat preferences of the tree pipit Anthus trivialis in an ancient oak wood-pasture, the Breite Natural Reserve, central Romania, with the aim of identifying the most significant habitat variables correlated with the presence of this species. In this way, we aim to highlight the need for conservation management of both the species and this particular habitat type, which are both declining across Europe. We found that the number of oaks with a diameter at breast height (d.b.h) > 1.27 m (equating to a circumference of 4 m) was the only variable with significant positive effect on the presence of the tree pipit. Shrub cover had significant negative effect on presence. Tree canopy cover, the clumping tendency of trees and distance from forest had no effect on the presence of this species in the study area. Our results show that the habitat requirements for the maintenance of the tree pipit impose the same active management needs as those for the maintenance of the ancient wood-pasture character of the Breite Natural Reserve, namely the control against hornbeam invasion and ensured viability of new oak sapling generations.
