[ID: 507] Trial 93 at the former Kronoparken Åheden, also known as trial 2179 at Rödåheden
PI: Fredrik Sjödin
One of the oldest forest trials in Sweden established 1907. Approx. 180 yrs old pine stand (2025). Valueable growth records with long continuity. New data, charts and summary of trial contributed by Björn Elfving 2025-10-29 added to Safedeposit by Fredrik Sjödin 30-10-2025. Added to series BB11 äldre gallringsförsök. https://silvaboreal.com/?p=trial&id=2179 Similar trials. Quote BE. The areas I have had contact with and that fit into this group are, in addition to site 93: site 1 near Lycksele, site 479 near Juktan, site 5 andersön in Storsjön, site 773 near Robertsfors (if it can still be saved from the construction of the Botniabanan; northern Sweden's oldest pine plantation), site 595 north of Norrköping, site 196 NW Vättern (cluster trials, preserve the 3-m cluster).

[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: 210] 7201 Gap trial Kälmyrbränna
PI: Fredrik Sjödin
The aim of this experiment is to study establishment, survival and growth of Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) planted in gaps ofpine dominated forest. Further, the study will also show how the gaps affect the stand increment compared to a stand without gaps. The theory is that the gaps increase incoming light and therefore also the increment.
[ID: 209] 7206 Gap trial Storkåtatjärnsbäcken
PI: Fredrik Sjödin
The aim ofthis experiment is to study establishment, survival and growth of Scots pine (Pinus ,ylvestris) and Norway spruce (Picea abies) planted in gaps of pine dominated forest. Further, the study will also show how the gaps affect the stand increment compared to a stand without gaps. The theory is that the gaps increase incoming light and therefore also the increment.

[ID: 107] Comparison of ecosystem C and N stocks in Norway spruce vs. Scots pine stands throughout Sweden
PI: Róbert Blaško
We are evaluating the performance of Norway spruce vs. Scots pine stands at the sites equally suitable for both species in the experiments at Kulbäcksliden 1028-1029, Flakaträsk 2458, Övra 1061, and Björkheden 1062. The aim is to evaluate how the different species productivity affects C and N stocks of he ecosystem and some of the important C fluxes; soil CO2 efflux and litterfall.

[ID: 77] S696 Holmmyrbrännan
PI: Ulla Nylander
Tree data from 1963-1981. S969 Holmmyrbrännan is a planting experiment on annual seasonal variation with pine with the intention of studying the declining effect of controlled burning. 4 blocks, 4 treatments (planting year), 8x10 plants per parcell. S969 is located at Kulbäcksliden Experimental Forest.
