A4067 Stuckenia pectinata - Potamogeton spp. - Ceratophyllum demersum Aquatic Vegetation Alliance

Type Concept Sentence: This alliance is found across the Great Plains in permanently flooded wetlands dominated by Stuckenia pectinata, Ceratophyllum demersum, Potamogeton spp., and Myriophyllum spp.


Common (Translated Scientific) Name: Sago Pondweed - Pondweed species - Coon''s-tail Aquatic Vegetation Alliance

Colloquial Name: Great Plains Submergent Aquatic Vegetation

Hierarchy Level:  Alliance

Type Concept: This alliance is found across the Great Plains in permanently flooded wetlands. Water is usually 1-2 m deep and ranges from fresh to saline. Submergent vegetation dominates and emergents have <10% cover. Dominants are usually Stuckenia pectinata, Ceratophyllum demersum, Potamogeton spp., and Myriophyllum spp.

Diagnostic Characteristics: Permanently flooded wetlands with <10% emergent vegetation and >10% submergent vegetation. Stuckenia pectinata, Ceratophyllum demersum, Potamogeton spp., and Myriophyllum spp. are usual dominants.

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: This is a widespread alliance and can likely be separated into two suballiances. One is composed of vegetation dominated by Stuckenia pectinata and is restricted to the northern Great Plains. This suballiance contains CEGL002003, CEGL002004, CEGL002005, and CEGL004528. The other suballiance has associations dominated by Potamogeton spp. and lacks significant Stuckenia pectinata. This suballiance occurs across the Great Plains and contains CEGL002044 and CEGL004529.

Physiognomy and Structure: This alliance is characterized by a moderate to dense cover of submerged aquatic macrophytes. The submersed leaves are filiform in shape and not conspicuous beneath the surface of the water.

Floristics: Submergent vegetation dominates and emergents have <10% cover. Dominants are usually Stuckenia pectinata, Ceratophyllum demersum, Potamogeton spp., and Myriophyllum spp.

Dynamics:  This alliance occurs in a generally semi-arid climate. Sites can occasionally be subject to water drawdown during droughts. These cycles of flooding and drawdown help cycle nutrients and tend to favor more floristic diversity than sites that are under water many years.

Environmental Description:  This alliance is found across the Great Plains in permanently flooded wetlands. Water is usually 1-2 m deep and ranges from fresh to saline. Parent material is often glacial till. The elevation of the plant associations ranges from 150-600 m in the Great Plains to 1200-2950 m in Montana and Colorado. Adjacent vegetation is midgrass and tallgrass prairie on the plains, and Carex aquatilis and Carex utriculata wetlands in Colorado.

Geographic Range: This alliance is found across the Great Plains and adjacent areas from southern Alberta to northwestern Ontario south to northwestern Arkansas and Texas and west to western Oklahoma and Montana.
