SPRUCE Site

Locality Description

The SPRUCE experimental site is located in the S1 bog within the Marcell Experimental Forest, which is located approximately 40 km north of Grand Rapids, Minnesota, USA. The MEF is within the Laurentian Mixed Forest Province, which is a transitional zone between boreal and broadleaf deciduous forests. The S1 bog is an ombrotrophic bog (a raised dome peat bog in which water and nutrient inputs originate from atmospheric sources). It is an 8.1-ha Picea-Sphagnum bog with hummock/hollow topography that was harvested in two successive strip cuts 5 years apart. The peatland has well-decomposed acidic peat (pH ~4) to varying depths, is overlain by 30?100 cm of less decomposed peat, and has an average depth of 2.5 m. Vegetation within the S1 bog is dominated by the tree species Picea mariana (mean height of 3 m in 1999. The bryophyte layer on drier hummocks is dominated by various species of Sphagnum (S. angustifolium, S. capillifolium, and S. fallax). Other bryophytes include Aulacomnium palustre (ribbed bog moss), Pleurozium schreberi (big red stem moss), and Polytrichum juniperinum (juniper polytrichum moss). The understory also supports a layer of ericaceous shrubs including Rhododendron groenlandicum (Labrador tea), Chamaedaphne calyculata (leather leaf), Kalmia polifolia (bog laurel), and Vaccinium angustifolium (low bush blueberry. The bog also has graminoids Carex spp. and Eriophorum spp., as well as the forb Maianthemum trifolium (three-leaved false Solomon's seal).
