Ludwidgia repens

Creeping primrose-willow

A fast-growing rooted wet-edge plant that can surge through Lakeshore water and soil, adding cover, nutrient uptake, and plant biomass while also becoming a management problem.

Identity & Origin +

Common Name: Creeping primrose-willow
Scientific Name: Ludwidgia repens
Realm: Freshwater
Biome: Lakeshore

Population Dynamics +

Current Estimated Population: Creeping primrose-willow is a visible Lakeshore/Freshwater Lake producer; exact current coverage and long-term plant balance remain unresolved.
Population Status: Established
Date Last Observed: April 26, 2026

Section Notes

Creeping primrose-willow provides rooted producer structure around the wet edge. A Ridgeback Sand Grasshopper was observed feeding on it in the Lakeshore on 2026-04-26. This supports one observed herbivory event, not long-term plant control or broad diet impact.

Trophic Ecology +

Trophic Level: Producer
Feeding Niche / Method: Photosynthetic primary producer
Dietary Inputs: Light, water, carbon dioxide, and soil or dissolved nutrients

Section Notes

Trophic classification is Producer. Food-web role: Rooted photosynthetic producer. Feeding method: Photosynthetic primary producer. Dietary inputs: Light, water, carbon dioxide, and soil or dissolved nutrients

Environmental Tolerances +

Life Cycle & Reproduction +

System Reproduction Status: Not assessed; growth/persistence are observed, but no reproduction mechanism is claimed from the current reviewed evidence.

Ecological Role & Symbiosis +

Freshwater

A wet edge habitat where water, roots, glass, mud, and plant cover let aquatic and terrestrial organisms overlap.

Freshwater

A still freshwater habitat where submerged plants, tiny grazers, shrimp, snails, and crayfish are rebuilding the lake's food web after fish pressure changed.
