A2508 Bacopa eisenii Aquatic Vegetation Alliance
Type Concept Sentence: This alliance encompasses pond and lake margins or floating beds of Bacopa eisenii. It is found in rice fields, muddy places, on wet soil or floating in ponds.
Common (Translated Scientific) Name: Gila River Water-hyssop Aquatic Vegetation Alliance
Colloquial Name: Gila River Water-hyssop Aquatic Vegetation
Hierarchy Level: Alliance
Type Concept: This alliance encompasses wetlands, including lake margins or floating beds, of Bacopa eisenii, found mostly below 100 m in elevation in coastal areas, but in the interior, it can occur as high as 1200 m. It is found in rice fields, muddy places, on wet soil or floating in ponds.
Diagnostic Characteristics: Pond and lake margins and floating beds dominated by Bacopa eisenii.
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Little information is available about the ecology or distribution of this plant community.
Similar NVC Types: No Data Available
note: No Data Available
Physiognomy and Structure: Herbaceous prostrate forb, generally <5 dm in height.
Floristics: No information is available at this time, but general observations suggest stands are monotypic Bacopa eisenii.
Dynamics: Bacopa eisenii has been known to invade rice fields (Barrett and Strother 1978), and there are three non-native species of Bacopa that do the same (Barrett and Strother 1978, Hickman 1993).
Environmental Description: This semi-aquatic plant species occurs in muddy places on the edges of ponds, lakes, and rice fields on wet soils and may also be found in floating water up to 3 dm deep (Barrett and Strother 1978, Hickman 1993). Plants are pollinated by honey bees (Barrett and Strother 1978).
Geographic Range: This alliance is found in California and Nevada.
Nations: US
States/Provinces: CA, NV
