James Island 2006 Survey for Rare Spring-flowering Plants Matt Fairbarns Aruncus Consulting June, 2006 Introduction In 2004, James Island was surveyed for the presence of rare plants and ecologically significant plant communities (James Island Conservation Assessment 2004 , Matt Fairbarns, 32 pp. plus appendices). A vegetation map of the island was produced and a number of rare plant occurrences were identified including populations of Contorted-pod Evening-primrose, Yellow Sand-verbena, Fleshy Jaumea, Beach Knotweed and Graceful Arrow-grass. The 2004 surveys were conducted in mid-July, too late to determine if spring-flowering species were present on the site. Accordingly the report recommended that spring surveys be conducted in subsequent years. The most critical dates for spring surveys for rare species in the Victoria area is late April and early May.
