Abstract:  Habitat loss, fragmentation, and declining habitat quality have created an extinction debt in boreal forests, which could be partly reversed by deliberately improving the habitat quality in managed areas outside reserves. We studied the effects of green‐tree retention and controlled burning on red‐listed and rare, deadwood‐dependent (saproxylic) beetles in a large‐scale field experiment in eastern Finland. Our factorial study design included 24 sites dominated by Scots pine (Pinus… 

Prescribed fires and retention trees help to conserve beetle diversity in managed boreal forests despite their transient negative effects on some beetle groups

Since the increase in the saproxylics was evident, and the population reductions of other species were transient, it is recommended the controlled burning with reasonable volumes of green‐tree retention to reduce negative effects of forestry on insect diversity.

Burning of Logged Sites to Protect Beetles in Managed Boreal Forests

It is concluded that burning of logged sites and leaving an adequate number of retention trees may be useful in the conservation of disturbance-adapted species and can be used to improve the environmental quality of the matrix surrounding protected areas.

High conservation value forests for burn‐associated saproxylic beetles: an approach for developing sustainable post‐fire salvage logging in boreal forest

Fire‐killed timber is considered as a loss of potential revenues and is thus increasingly salvaged, though not without concerns for biodiversity conservation. Indeed, a large diversity of

Restoration of Young Forests in Eastern Finland: Benefits for Saproxylic Beetles (Coleoptera)

It is suggested that fire could be introduced in neighboring areas in approximately 5-year intervals to maintain populations of the most demanding pyrophilous species and to restore young forests where biodiversity values are initially low.

Restoration of natural legacies of fire in European boreal forests : an experimental approach to the effects on wood-decaying fungi

Effective fire suspension in Fennoscandian boreal forests has caused a number of species to become threatened. To compensate for the negative ecological impacts of fire elimination, prescribed

Wildfire yields a distinct turnover of the beetle community in a semi-natural pine forest in northern Sweden

Background Fires have been an important natural disturbance and pervasive evolutionary force in the boreal biome. Yet, fire suppression has made forest fires rare in the managed landscapes in



Dead trees left in clear-cuts benefit saproxylic Coleoptera adapted to natural disturbances in boreal forest

It is concluded that dead trunks left in the clear-cut areas may host not only generalist saproxylic species but also many beetle species specialized to warm, sun-exposed environments, and such species may not be able to survive in closed forests.

Invertebrates and Boreal Forest Management

Logging has ecological effects on invertebrates in Fennoscandian boreal forest. Especially affected are species associated with micro‐habitats of natural old‐growth forest, such as coarse woody

Immediate effects of fire-severity on soil invertebrates in cut and uncut pine forests

Forest Fragmentation in Fennoscandia: Linking Habitat Requirements of Wood-associated Threatened Species to Landscape and Habitat Changes

Results from current research indicate the need to restore and recreate natural fire-originated early successional stages where the amount of coarse woody debris is high, which is potentially a very effective way to sustain populations of several threatened wood-associated species.

Deforestation and Fire Impact on Edaphic Insect Larvae and Other Macroarthropods

Three sites representative of forest successions in the Lake Duparquet region (situated in the southern part of the boreal forest, Abitibi, PQ, Canada) were chosen for this experiment and the effects of deforestation on the communities of the 3 sites were analyzed.

Extinction Debt of Protected Areas in Developing Landscapes

Abstract:  To conserve biological diversity, protected‐area networks must be based not only on current species distributions but also on the landscape's long‐term capacity to support populations. We

Sampling the rarest: threatened beetles in boreal forest biodiversity inventories

It is suggested that the best alternative in surveying threatened species in boreal forests is a combination of intensive direct searching and trunk window traps, whereas many other standard methods gave relatively poor results.

Extinction debt and species credit in boreal forests: modelling the consequences of different approaches to biodiversity conservation.

It generally pays to concentrate the efforts of improving forest quality at certain areas rather than to spread the same total effort evenly and therefore thinly throughout the entire forest landscape, which would facilitate the migration of target species to the restored forests.
