Saltmarsh Goosefoot
Chenopodium chenopodioides
This rare species is known in the Channel Islands only from a brackish pool on Lihou, demonstrating how specialised plants can be in coastal environments. Its succulent-like leaves tolerate saltwater fluctuations. As an annual adapted to saline habitats, its survival depends on the pool’s unique water chemistry and the island’s minimal disturbance.
- Habitat: Brackish pools, saltmarsh edges, and muddy coastal depressions.
- When to See: Foliage and small greenish flowers appear in summer; seeds in late summer/autumn.
- Length: Usually under 30 cm in height, sprawling or upright habit
