英语百科

Halosere

A salt marsh

In ecology, a halosere is a succession in a saline environment. An example of a halosere is a salt marsh.

In a river estuary, large amounts of silt are deposited by the ebbing tides and inflowing rivers.

The earliest plant colonizers are algae and eel grass, which can tolerate submergence by the tide for most of the 12-hour cycle and which trap mud, causing it to accumulate. Two other colonizers are Salicornia and Spartina, which are halophytes, i.e. plants that can tolerate saline conditions. They grow on the inter-tidal mudflats with a maximum of four hours' exposure to air every 12 hours.
