Sustainable, well-planned, near to nature forest management deals with the production of raw timber. The classical central disciplines are silviculture, forest growth and yield and forest planning supplemented by information on the timber market, storage and bio-energy. Loss events, such as windfall, bark beetle or game damage, present an ever re-occurring challenge to forest personnel. Successful management in avoiding and limiting risks and damage is part of an effective operational strategy.

Bark beetles, beware: The three-toed woodpecker!

Three-toed woodpeckers predominantly prey on bark beetles and play a key role in controlling beetle populations in forests dominated by conifers. Their impact is greatest where they occur year-round and thus also breed there. For this, the average deadwood volume needs to be at least 33 m3 per hectare.

Tree growth on the fast track

Continuous monitoring of growth on experimental forest plots since 1870 – this is a global rarity. Just as fascinating is what this observation has revealed: our trees have been growing faster over the last five decades than they did before.

Forest protection with sessile oak

Sessile oak is a highly desired tree species. However, a few of the many residence found living on the tree are causing problems for it. It is particularly precarious for the tree when early and late defoliators appear together. (6)
Scent detection dogs for the Asian longhorn beetle

Dogs are known to be used for explosive or medical detection or as drug-sniffing dogs. But did you know you can also use them as detection dogs in timber trade? The Austrian Research Centre for Forests (BFW) trains and works with the animals to detect the Asian longhorn beetle and the Citrus longhorn beetle. (8)
Tracking the bark beetles

Bark beetles are capable of causing large-scale damage during mass propagation. With the help of the bark beetle monitoring program, data for scientific research is collected and important information for the forestry praxis is made available. (9)
Chestnut blight: symptoms, biology and management strategies

Chestnut blight is a dangerous fungal disease of chestnut (Castanea) species. Within 30 years it almost completely destroyed the extensive chestnut forests in the USA. Fortunately, the impact of the disease in Europe is less dramatic. (64)
Foreign tree species

Some euphorically endorse non-native tree species while others demonize them. Where in lies the truth? In Europe many foreign tree species have been established for a long time. Is that good or bad? Can all the tree species be lumped together?

Avalanche: foundations for effective protection

An effective avalanche protection depends on many factors: protection forests, protection barriers and an avalanche warning system are important prerequisites for example. This article outlines how avalanches happen and what you can do about them.

Drought in the forest

Forecasts suggest that our native forest trees will face increasing drought stress. How are trees dealing with this and what measures can you take?

Damage caused by drought

Dry cracks and dryness caused by frost are damage symptoms which can occur due to water shortages in the forest. What are the causes and what measures help when the risk is identified?
