Types

Reedbeds vary in the species that they can support, depending upon water levels within the wetland system, climate, seasonal variations, and the nutrient status and salinity of the water. ''Reed swamps'' have 20 cm or more of surface water during the summer and often have high invertebrate and bird species use. ''Reed fens'' have water levels at or below the surface during the summer and are often more botanically complex. Reeds and similar plants do not generally grow in very acidic water; so, in these situations, reedbeds are replaced by bogs and vegetation such as poor fen. Although

Uses

Constructed wetlands

Constructed wetlands are artificial swamps (sometimes called ''reed fields'') using reed or other marshland plants to form part of small-scale sewage treatment systems.

s living on the root system and in the litter. These organisms utilize the sewage for growth nutrients, resulting in a clean effluent. The process is very similar to aerobic conventional sewage treatment, as the same organisms are used, except that conventional treatment systems require artificial aeration.

Treatment ponds

Treatment ponds are small versions of constructed wetlands which uses reedbeds or other marshland plants to form an even smaller water treatment system. Similar to constructed wetlands, water trickling through the reedbed is cleaned by

s living on the root system and in the litter. Treatment ponds are used for the water treatment of a single house or a small neighbourhood.
