PI: Urban Nilsson
Testing the effects of several clearcut treatments on the growth of birch. One site per experimental park.
[ID: 272] Degerfors - Establishment of a new stand managed with precisely added nutrient load
PI: Fredrik Sjödin
Summary This trial aims to monitor effects of a specific and precisely added nutritive load (arginine) in the establishment of a new generation plantlings. The trial also aims to repeat the same load yearly after establishment to see growth effects. The trial is set up as parcels of pine, spruce and birch both in mixtures and monoculture. Nutrition management, growth and survival of common species in monocultures and in mixed stands. Established 2020-06 Also see in same trial series location Fredrika, Västerbotten and Asa, Småland.

[ID: 174] Birch spruce replacement
PI: Emma Holmström
The purpose of the experiment is to have long term measurements of growth and stand development of the two species in monoculture vs mixture. The first treatments are initiated after regeneration on sites with planted Norway spruce and naturally regenerated birch where the two species are within the same average heights. First treatment is a pre-commercial thinning aiming for stand composition in four different levels : Every block is divided in four treatments with 100 % Norway spruce (NS), 100 % Birch, mixture 33 % NS and 66 % Birch, mixture 66 % NS and 33 % birch.
[ID: 119] Natural regeneration of birch in northern and mid Sweden
PI: Felicia Lidman
Study of birch seedling germination depending on soil moisture, different soil scarification intensities, time since soil scarification and seed rain. Layout: Natural regeneration and seeding of Birch in different combinations of soil scarification and soil moisture. 3 different soil preparations and 3 different soil moisture classes are monitored: - Dry, mesic moist. - Bare mineral soil, mixture with org.m. and and mineral soil and a control. Location: 108 plots outside Vindeln (Buberget and Pompej) and 108 plots outside Tierp (Tierp and Dragongate). one plot was 1 x 1.5 m.
