Which long-term ecological change accelerates during a barrier island breaching event?

💡 Explanation

Saltwater marshes expand inland due to breaching because tidal prism increases via tidal exchange; therefore, saltwater intrusion accelerates rather than plant migration or equilibrium shifts because breaching drastically alters the established salinity gradient.
