In the case of submerged vegetation, community changes are related to alterations of the salinity and eutrophication regime, manifested in a decreased coverage and the extinction of some species.

Biomanipulation: A Useful Tool for Wetland Rehabilitationn wetlands. This chapter highlights pros and cons of biomanipulations in wetlands, and suggests that an extension of the current biomanipulation paradigm beyond fish management, to consider interventions in other components of wetland communities, can be useful for rehabilitating degraded wetlands such as Las Tablas de Daimiel.
