Plant Guide : Vegetation Type : Freshwater marsh

Bulrush

 

A freshwater marsh is a shallow expanse of still, or slowly moving fresh water, often by the side of a lake or river. It is characterized by "emergent vegetation", tall, grass-like plants such as cattails, bulrushes and reeds that live with their roots in the mud and their leaves and flowers in the sun.

In San Elijo Lagoon, freshwater marshes are found along Escondido Creek, just east of the Reserve boundary. Also, pockets of freshwater marsh occur in East Basin intermixed with more brackish conditions. These are somewhat ephemeral, expanding during wet years and retreating during drought conditions.
