In a comparative study we investigated woodpecker abundance in forest landscapes with different proportion of native pine forest and spruce plantations in western Norway. In 100 circular study plots of 100 ha each we recorded 38 white-backed –Dendrocopos leucotos, 22 grey-headed –Picus canus, 13 great spotted –Dendrocopos major, 6 green –Picus viridis, and 2 lesser spotted –Dendrocopos minor woodpeckers in the breeding season. The mean number of recorded woodpecker species peaked at 20–40… Expand

Woodpeckers in Western Norway: the White-backed Woodpecker is still the most common species
The pine-dominated forests of Western Norway have been found to harbour viable populations of woodpeckers, including the highly specialized White-backed Woodpecker Dendrocopos leucotos. The aim ofExpand
Effects of non-native spruce plantations on small mammal communities in subarctic birch forests
TLDR
Seasonal small mammal population abundances in spruce plantations with four birch forest varieties are contrasted, indicating that growth rates in the reproductive season were more influenced than winter declines, and managingSpruce plantations to maintain a mix of different tree species and high spatial heterogeneity will reduce the negative impacts on the small mammal community.

Suitability of Poplar Plantations for a Cavity-Nesting Specialist, the Lesser Spotted Woodpecker Dendrocopos minor, in the Mediterranean Mosaic Landscape
Abstract. Monocultures of even-aged trees in short rotation are a forest system of low ecological complexity that has been described as unsuitable for the establishment of stable populations ofExpand
The white-backed woodpecker: umbrella species for forest conservation planning?
TLDR
Considering its indicator value, its specialised habitat requirements and its potential as a communication tool, using the white-backed woodpecker as an umbrella species may provide a coarse filter for the conservation of several other deciduous forest species. Expand
Specialised woodpeckers and naturalness in hemiboreal forests - Deriving quantitative targets for conservation planning
In many parts of the world’s forests, intensive management has resulted in habitat loss for several species. Among these, specialised woodpeckers (Aves: Picidae) have been affected negatively due toExpand
Retention of native vegetation within the plantation matrix improves its conservation value for a generalist woodpecker
The suitability of plantation monocultures for the conservation of forest animals is an issue under continous debate. The adaptability of forest dwellers and the forest management regime seem to playExpand
Capacity of older plantations to host bird assemblages of naturally-regenerated conifer forests: A test at stand and landscape levels
TLDR
Older spruce plantations did not provide suitable habitat for some species, mainly cavity nesters, and mature, naturally-regenerated forest patches are essential components of intensively-managed forest landscapes to maintain rich forest bird assemblages. Expand

Scale-Dependent Responses of Predators and Their Prey to Spruce Plantations in Subarctic Birch Forests in Winter
TLDR
Predators and prey were spatially and temporally related at the 2 smallest scales in a manner that may be explained by year- and standspecific snow conditions affecting the predator—prey interactions within the community. Expand
Snag abundance and species composition in a managed forest landscape in central Japan composed of Larix kaempferi plantations and secondary broadleaf forests.
TLDR
Snag species that were positively correlated with stand age were the main species in secondary broadleaf forests in this area, and long-rotation plantations are useful for retaining snags compared to standard- rotation plantations. Expand

Effects on avian diversity of introducing spruce Picea spp. plantations in the native pine Pinus sylvestris forests of western Norway
TLDR
It is argued that, when mixing two habitat types A and B, the ratio of these habitats that maximize avian diversity depends on the ratios of species confined to habitat A andB, as well as the number of species favoured by the mixture of A and A. Expand
Woodpecker assemblages in natural and managed boreal and hemiboreal forest: a review
TLDR
There is a close connection between the degree of specialization of woodpeckers, the changes in forests and recent population trends, and woodpecker species as a group are in conflict with intensive forest management. Expand
Increasing insect abundance by killing deciduous trees: a method of improving the food situation for endangered woodpeckers
TLDR
Notching, in general, seemed to create good foraging trees in the short-term whereas girdling produced trees of a longer-term value, and a combination of the two methods is suggested to improve the local food situation for the white-backed woodpecker. Expand
The effect of habitat loss on a deciduous forest specialist species: the White-backed Woodpecker (Dendrocopos leucotos)
TLDR
This study extends earlier analyses concerning range contraction and explores whether there exists a threshold in the amount of suitable habitat below which the species will not persist, and if there is a nonlinear decline in population size as suitable habitat in the forest landscape is reduced.

Population contraction of the white-backed woodpecker Dendrocopos leucotos in Finland as a consequence of habitat alteration
TLDR
The population decline of the white-backed woodpecker Dendrocopos leucotos in Finland is presented and factors affecting this decrease are analysed and a network of deciduous forests favoured by the Woodpecker has been proposed. Expand
