A3839 Pinus banksiana - Pinus resinosa - Quercus ellipsoidalis Subboreal Rocky Woodland Alliance
Type Concept Sentence: This alliance is found in subboreal regions of the northwestern Great Lakes region in Canada and the United States. Stands typically occur on shallow, well-drained rocky sites. Soils are thin (<50 cm) to absent on bedrock. The tree canopy is scattered, often stunted, and dominated by Quercus ellipsoidalis, Pinus banksiana, Pinus resinosa, or Pinus strobus.
Common (Translated Scientific) Name: Jack Pine - Red Pine - Northern Pin Oak Subboreal Rocky Woodland Alliance
Colloquial Name: Subboreal Jack Pine - Red Pine - Oak Rocky Woodland
Hierarchy Level: Alliance
Type Concept: This alliance is found in subboreal regions of the northwestern Great Lakes region of the United States and Canada. Stands typically occur on shallow, well-drained rocky sites. Soils are thin (<50 cm) to absent on bedrock. The tree canopy is scattered, often stunted, and dominated by Quercus ellipsoidalis, Pinus banksiana, Pinus resinosa, or Pinus strobus. It can vary from pure deciduous to mixed evergreen-deciduous to evergreen. Shrub and herbaceous layers are highly variable, ranging from sparse to up to 80% cover. A nonvascular layer can be present or absent and is typically dominated by Cladonia spp.
Diagnostic Characteristics: Diagnostic features of the type include the forest or woodland canopy consisting primarily of Quercus ellipsoidalis, Pinus banksiana, Pinus resinosa, or Pinus strobus, and a rocky substrate, with dry herbaceous, moss, and lichen species.
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Review of the associations within this alliance may be needed and splitting of one or both might be needed to create a mixed Pinus resinosa - Pinus strobus bedrock association separate from Pinus banksiana bedrock association within this alliance. See Minnesota FDn22a (jack pine) versus b/d (red pine-white pine) (Minnesota DNR 2003). For a fuller description of this alliance, see FDn22 in Minnesota DNR (2003).
