Front

What is the function of mangrove trees in a salt marsh?

Back

Mangrove trees provide habitat, stabilize shorelines, and contribute to nutrient cycling in salt marsh ecosystems.

Front

What is the role of plant roots in sediment stabilization?

Back

Plant roots help to anchor sediments in place, preventing erosion and promoting ecosystem stability.
