The spatial pattern of nine 5-yr age-classes of trees in a grove of Trembling Aspen (Populus tremuloides) was studied by applying nearest-neighbor analysis to a transect.


Biomass And Nutrient Distribution In Aspen, Pine, And Spruce Stands On The Same Soil Type In Minnesota, David H. Alban, Donald A. Perala, Bryce E. Schlaegel Jan 1978

Biomass And Nutrient Distribution In Aspen, Pine, And Spruce Stands On The Same Soil Type In Minnesota, David H. Alban, Donald A. Perala, Bryce E. Schlaegel

Aspen Bibliography

Vegetation and soils were sampled in adjacent 40-year-old stands of red pine (Pinus resinosa Ait.), jack pine (Pinus banksiana Lamb.), white spruce (Picea glauca (Moench.) Voss), and aspen (Populus tremuloides Michx., P. grandidentata Michx.) on a very fine sandy loam soil in north-central Minnesota. Total tree biomass was greatest for red pine followed by by aspen, spruce, and jack pine. Nutrient weights (N, P, K, Ca, Mg) in the trees were greatest in aspen followed generally by spruce, red pine, and jack pine. Particularly large proportions of biomass and nutrients were found in aspen bark and …
