The establishment of Spartina in the Tamar Estuary, Tasmania

Abstract

Spartina anglica was introduced into the Tamar Estuary, Tasmania, in 1947. Initially spread was slow but subsequently rapid. It is capable of colonizing all rock types and sediments available in the estuary but fine sediments provide the most and basalt the least suitable substrate. It colonises all available slopes (10 degrees -28 degrees). As a result of the introduction, mud banks become stabilized and the navigable channel thereby safeguarded. The spread of Spartina has, however, adversely affected some beaches and private jetties.
