Mudflag (Pennantus limosus)

Alias: None
Origin: Berinu (deltas)

The Mudflag is a sturdy, pennant-shaped plant native to the deltas of Berinu. Its stiff, upright leaves act as natural markers for water currents and trap silt, stabilizing the muddy substrates of wetland ecosystems. Its presence indicates healthy delta environments with consistent tidal flow, supporting diverse aquatic life.

Terrain

Mudflags thrive in the muddy, brackish deltas of Berinu, often found alongside Saltroot Mangrove and Brineth Herb. They are absent in arid, volcanic, or deep ocean biomes.

Lifespan

Mudflags live 5–10 years, reaching maturity at 1 year and producing seeds during tidal flooding seasons.

Height

Mature Mudflags reach a height of 0.5–1.2 m, with a spread of up to 0.6 m. Younger plants (under 1 year) are 0.2–0.5 m tall.

Uses

• Ecological Role: Stabilizes deltaic soils by trapping silt, preventing erosion, and supporting fish nurseries and other aquatic species.
• Cultural Use: Used by Berinese communities to mark navigable channels in deltas, symbolizing stability and flow.
• Guidance: Plant to stabilize silt in delta restoration projects; use as channel markers during expeditions; avoid harvesting during strong tidal shifts to prevent destabilization.

Notes

Documented during the Era of Absolute Expansion (~3,000 years before modern Geba), Mudflags were noted in the Comprehensive Field Codex for their critical role in maintaining delta ecosystems. Their ability to indicate current flow and stabilize sediment makes them essential for ecological surveys and navigation in Berinu’s wetlands. They remain extant, contributing to the ecological balance of Berinu’s deltas.
