A “feeling of ownership” is reflected in the decisions of private forest owners

Social and emotional characteristics may play important roles in influencing the behaviour of private foresters. Owners who have inherited their property may feel a moral obligation to take care of that forest. A Finnish study suggested four types of forest owners, based on in-depth interviews and the theory of psychological ownership. The four types represent various levels of control and identity, based on emotions.

Spruces grow better after early cleaning

Precommercial thinning is usually undertaken when a stand is 2-4 m tall. Early cleaning – a thinning conducted when the stand is only about 1 m tall – offers an attractive alternative to reduce costs and ease competition on the released crop trees. In a study from Finland, early cleaning was shown to increase mean diameter of the released spruces compared to a control without any treatment.

More moose mean hunters are willing to spend more

The hunting value, expressed as the “willingness to pay” of an average moose hunter, increases with a larger moose population and permitted bag. This was revealed by a survey of Swedish hunters. The average value of moose huntingwas 7000 SEK per hunter. If the moose population doubled from today’s levels, the hunting value would increase by 1000 SEK per hunter. If the population fell to half the current level, the hunting value would decrease by 1300 SEK.

Forest use has a long-term effect on dead wood

It is difficult to determine how humans have affected the structure of the forest from a long-term historical perspective. A study from Karelia took on this challenge by looking at forest structure in relation to distance from abandoned villages. The researchers found that forests close to villages had trees of about 130 years age and contained very little dead wood. The most remote stands, 2-2.5 km from the villages, were generally more than 200 years old and had a diverse dead wood composition.

LiDAR can be used to assess forest road characteristics

Timber transport using long and heavy log trucks requires a good knowledge of the road system and its accessibility. A study in Oregon, USA, used airborne LiDAR data to obtain information about roads. The authors found that the data was good enough to estimate centerlines and grades of the roads, but some caution should be used in estimating horizontal curve radii, particularly on sharp bends.
