A3921 Utricularia macrorhiza - Utricularia minor - Utricularia ochroleuca Aquatic Vegetation Alliance
Type Concept Sentence: This aquatic herbaceous alliance is dominated by Utricularia macrorhiza, Utricularia minor, or Utricularia ochroleuca, on lakes and ponds forming sparse to dense masses of nearly monotypic submerged vegetation. It is found throughout low elevations in the western U.S. and possibly western Canada.
Common (Translated Scientific) Name: Common Bladderwort - Lesser Bladderwort - Yellowish-white Bladderwort Aquatic Vegetation Alliance
Colloquial Name: Western Bladderwort Aquatic Vegetation
Hierarchy Level: Alliance
Type Concept: This aquatic herbaceous alliance is dominated by submerged and entirely floating (not rooted in soil) Utricularia macrorhiza, Utricularia minor, or Utricularia ochroleuca. They form sparse to dense masses of nearly monotypic submerged vegetation. Stands occur in lakes and ponds, usually with perennial water and are found throughout low elevations in the western U.S. and possibly western Canada.
Diagnostic Characteristics: Aquatic beds dominated by Utricularia macrorhiza, Utricularia minor, or Utricularia ochroleuca.
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: These occurrences have not been well-documented; more information is needed on their ecology and distribution as aquatic communities.
Similar NVC Types: No Data Available
note: No Data Available
Physiognomy and Structure: Fine-leaved herbaceous aquatic forb, submerged to partially emergent.
Floristics: Stands are dominated by a single species or a mix of Utricularia macrorhiza, Utricularia minor, or Utricularia ochroleuca. Utricularia spp. are insectivorous and characterized by large bladders blackened with the remains of aquatic invertebrates.
Dynamics: No Data Available
Environmental Description: Stands occur in lakes and ponds, usually with perennial water. It is not clear if this alliance favors eutrophic conditions or may be enhanced by enriched runoff in agricultural or urban landscapes.
Geographic Range: This alliance is found throughout low elevations in the western U.S. and possibly western Canada.
