An intertidal wetland is a the area along a shoreline that is exposed to air at low tide and submerged at high tide. This type of wetland is defined by an intertidal zone and includes its own intertidal ecosystems.

The main types of intertidal wetlands are mudflats (e.g., mangrove swamps) and salt marshes. The mangrove swamps are encountered along tropical shores and are characterized by tree vegetation, while salt marshes are mostly found in temperate zones and are mostly grass ecosystems.

Intertidal wetlands are commonly encountered in most estuaries. Intertidal wetland ecosystems are amongst the most productive plant communities and often constitute a large part of the estuary areas.

Charlotte Elisabeth Grace Roche (born 18 March 1978 in High Wycombe, England) is a British-born German television presenter and author.

Roche, who is bilingual in English and German, is the daughter of an engineer and a politically and artistically active mother. She has lived in Germany since the age of eight, having previously lived in London and the Netherlands. She grew up in the Lower Rhine region, in a family with liberal views. Her primary school was in Niederkrüchten. In 1989 she went to the secondary school, St. Wolfhelm Gymnasium, in the neighbouring town of Schwalmtal. When she was 14 years old she moved to Mönchengladbach, where she was educated at the Hugo Junkers Gymnasium in the suburb of Rheydt. She left school after the 11th grade, at the age of 17. She obtained initial stage experience in drama groups during her time at school.

Roche left home in 1993 and founded with three female friends the garage rock group The Dubinskis. The members performed several intimate gigs in a small tour before the two other members pulled out. There followed a period where she undertook anything that would shock and offend people — self mutilation in order to paint with blood, drug experiments, or shaving her head. After successfully auditioning for the German music channel Viva, she worked there for several years as a video jockey and presenter, as well on the sister channel Viva Zwei, where she presented her show Fast Forward.
