By trapping and binding sand particles, beach grasses facilitate the formation and maintenance of dunes, acting as natural barriers against the forces of coastal erosion.

Habitat Creation: Beach grasses provide essential habitat for a diverse array of wildlife. The dunes formed and maintained by these grasses offer nesting sites for shorebirds, refuge for small mammals, and a haven for a variety of insect species. The intricate network of dune ecosystems, sustained by beach grasses, supports a rich tapestry of life, contributing to the biodiversity of coastal regions.

Coastal Resilience: In the face of increasingly severe weather events and rising sea levels, the resilience of coastal ecosystems is of paramount importance. Beach grasses play a pivotal role in enhancing the resilience of coastal areas by mitigating the impacts of storms, reducing the vulnerability of shorelines to erosion, and safeguarding inland areas from the encroachment of sand and saltwater.

Soil Stabilization: The intricate root systems of beach grasses help bind the sandy substrate, preventing it from shifting and becoming airborne as blowing sand. This function is essential for maintaining the stability of coastal soils and preventing the loss of valuable land to erosion.

Carbon Sequestration: Beach grasses contribute to carbon sequestration, capturing and storing atmospheric carbon dioxide in their biomass and in the soils of dune ecosystems. This process aids in mitigating climate change and its impacts by reducing the concentration of greenhouse gases in the atmosphere.

These multifaceted contributions underscore the indispensable role of beach grasses in preserving the ecological balance of coastal regions and sustaining the myriad benefits that these environments provide to both wildlife and human communities.

The grass on the beach is called beach grass or dune grass. It helps to stabilize the sand dunes and prevent erosion.

Threats to Beach Grass
