Deliberate anthropogenic introductions of exotic trees to NW Europe are not particular new; traces of planting near the castles and monasteries dates back to the late Roman period and early medieval age [1]. The first reforestation and forest culture initiatives in Norway were taken in the 1740s [2-5], and larch plantations in western Norway were established in the 1780s [6]. However, the ideas...

A three-year project, financed by EU, European Regional Developmental Fund, will be carried out in 2011-14 as a collaborative effort with Finnish Forest Research Institute as a main performer, and Eastern Finland University and a commercial company Taimityllilä Oy as partners. Three new researchers are engaged by the project. The aim of the project is to deepen knowhow and develop technology fo...

The demand for bigger, better, faster-growing seedlings has been ever-growing. As a result, forest seedling production is a continually evolving technology in reforestation. Evaluating seedling quality is crucial for understanding seedling development in the nursery, as well as subsequent field growth and survival. Stock quality, however, often is assessed inconsistently and on only a limited b...

Although the evolution of principles, procedures, and predictive abilities related to seedling quality throughout plant production chain (i.e., from seeds sustainable plantations) has been reviewed over past decades in various technical scientific publications, there is still a need develop integrate new efficient practices forest nurseries at planting sites, order improve morphophysiological s...

Supplying mineral nutrients at the proper rate and in the proper balance has a major effect on seedling growth rate but, more importantly, on seedling quality. In addition, mounting concerns about fertilizer pollution are increasing awareness of the benefits of precision fertilization. Because they reflect actual mineral nutrient uptake, plant tissue tests are the best way to monitor a fertiliz...

A study of nursery stock performance was conducted on four sites in the Tongass National Forest in southeastern Alaska: two sites at Fire Cove (Ketchikan Ranger District [R.D.]) and one each at Anita Bay (Wrangell R.D.) and Eight Fathom (Hoonah R.D.). Containerized Sitka spruce seedlings used in the study were grown at USDA Forest Service nurseries in Petersburg, Alaska, and Coeur d'Alene, Idah...
