Income from non-timber products and services are expected to grow in Norwegian forestry the coming decades. As the forest holdings in Norway are relatively small, formalized cooperation between forest owners is essential to be able to create value from non-timber products and services. Theories of social capital and rural capital are used to create hypothesis on the importance of local networks and business climate. Entrepreneurship theory is used to explain innovation behavior of forest owners. Theories of innovation systems are used to study the importance of institutional factors and actors. We test our theory-based research questions with new survey data on Norwegian forest owner?s experiences with innovation in non-timber products and services. We also present two case-studies from the Agder-Telemark district in Norway where we analyze factors explaining innovation success in non-timber products and services. The forest owners associations play an essential role in facilitating non-timber value-added activities and the article concludes with some recommendations on how these associations could be more effective in promoting innovation in non-timber products and services.

Adaptive traits in Picea abies (Norway spruce) progenies are influenced by the maternal temperatures during seed production. Here, we have extended these studies by testing the effects of maternal photoperiod and temperature on phenology and frost hardiness on progenies. Using eight phytotron rooms, seeds from three unrelated crosses were made in an environmental 2 x 2 factorial combination of long and short days and high and low temperatures. The progenies were then forced to cease growth rapidly at the end of the first growing season. An interactive memory effect was expressed the second growth season. Progenies from high temperature and short days, and from low temperatures and long days, started growth later in spring, ceased shoot growth later in summer, grew taller and were less frost hardy in the autumn than their full siblings from low temperatures and short days, and from high temperatures and long days. Norway spruce has developed a memory mechanism, regulating adaptive plasticity by photoperiod and temperature, which could counteract harmful effects of a rapidly changing climate.
