Which type of plants are commonly found in salt marshes?

Salt marshes are coastal ecosystems characterized by their salt-tolerant vegetation, which is specifically adapted to the unique environmental conditions present in these areas. The correct choice, salt marsh grasses, comprises various species that can thrive in saline conditions and are capable of withstanding the flooding and drying cycles typical of marsh environments. These grasses play a crucial role in stabilizing the soil, providing habitat for wildlife, and helping to filter pollutants from the water.

In contrast, deciduous trees generally require more freshwater and do not tolerate high salinity, making them unsuitable for salt marshes. Succulent cacti are primarily found in arid, desert environments, not in wet or saline habitats. Flowering shrubs, while they can adapt to various environments, are not specifically associated with salt marshes and typically prefer different habitats. Thus, the presence of salt marsh grasses is essential for the ecosystem's health and functionality in salt marshes.
