Widespread High-Risk Invasive Species Were Identified Where Control Would Be Possible. (Department of Agriculture (2014). Biosecurity Workshops Report. Department of Agriculture); Survey- 5 Out Of 13 Sites Held S. Squalidus, Of Which Four Comprised <100 Individuals And One >3000 Individuals. Control Of S. Squalidus Is Likely To Be Significantly More Challenging, Due To The Short Generation Time And Its Presence Across Areas Of Mpa With Restricted Access. Due To The Potentially Negative Impacts On The Health Of Both Humans And Livestock, Management Of This Species Should Continue To Be A Significant Concern. Whilst Eradication Is Unlikely To Be Possible, Containment May Be Possible With Continued Concerted Control And Surveillance For New Populations. (Lewis, R. (2014) Invasive Plants in the Falkland Islands. Royal Botanic Gardens, Kew.); Ragwort Is Present In The Mount Pleasant/ Mare Harbour Area And One Plant Was Recorded In Stanley But Has Since Been Removed (B. Summers, Pers. Comm.). (Whitehead, J. (2008) Priorities for Control: A Risk Assessment of Introduced Species on the Falkland Islands. South Atlantic Invasive Species Project ); Naturalised. Some plants controlled (R. Lewis 2013). Not cultivated. Found in built up areas and gardens, improved grassland, acid grassland. c. 60 m. Very rare. East Falkland (Mount Kent, Mount Pleasant Complex, Stanley). (Upson R. & Lewis R. (2014).
