Abstract
Introducing new plants to an area may have both positive and negative effects on the environment, economy and community. To minimise the negative environmental impact of introducing new agricultural species, DPIRD conducts a risk assessment procedure based on widely accepted scientific standards. This report assesses Caribbean stylo (Stylosanthes hamata). Caribbean stylo (Stylosanthes hamata) is an annual or short-lived perennial herbaceous legume. Individual plants behave as self-regenerating annuals or biennials. In the Northern Territory up to 40% of plants persist from one wet season to the next (Cameron 2010), but this varies depending on the length of the dry season. It has a semi-erect or sometimes prostrate growth habit with many fine stems and is generally 25-40cm in height (up to 75cm), and may develop a low crown under grazing.
