A4130 Pinus resinosa - Pinus strobus Subboreal Forest Alliance
Type Concept Sentence: This alliance, found in the northwestern Great Lakes region of the United States and Canada, contains Pinus resinosa and Pinus strobus forests on dry-mesic to mesic sites.
Common (Translated Scientific) Name: Red Pine - White Pine Subboreal Forest Alliance
Colloquial Name: Subboreal Red Pine - White Pine Forest
Hierarchy Level: Alliance
Type Concept: This alliance, found in the northwestern Great Lakes region of the United States and Canada, contains Pinus resinosa and Pinus strobus forests on dry-mesic to mesic sites. Sites occur either on well-drained upper slopes and broad ridgetops, or somewhat moist sandy sites. Occasionally Picea mariana or Picea glauca are present. In somewhat more mesic conditions, Abies balsamea and Acer rubrum are present, especially in the understory. Shrubs include Acer spicatum, Vaccinium angustifolium, and Vaccinium myrtilloides.
Diagnostic Characteristics: This alliance contains Pinus resinosa and Pinus strobus forests on dry-mesic to mesic sites in the sub-boreal northwestern Great Lakes region of the United States and Canada.
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This alliance balances overstory dominance with understory floristics and moisture, such that both dry-mesic and mesic sites dominated by Pinus resinosa and Pinus strobus are brought together, distinct from sites dominated by Pinus banksiana and Picea mariana (or rarely Picea glauca). This approach differs from the Minnesota decision to emphasize habitat and ground layer floristics over the overstory, such that FDn32 and FDn33 both contain pine types and spruce types (Minnesota DNR 2003).
