Bay leaves showing symptoms of infection
When visiting the excellent BLDG BLOG this morning I came upon a most interesting and lengthy post that's worth reading if interested in plant quarantine and the complex issue of species being threatened by imported pests. In a global economy of trading, travel and transport across borders plants dont have passports saying for example they're from China when they are shipped from The Netherlands into the UK - problems can result. Trading is often put before quarantine!.
Sarah Redstone is Plant Health and Quarantine Officer at the Royal Botanic Gardens at Kew, UK - home of the world's largest collection of living plants. In addition to screening and isolating all incoming and outbound plant material, she is currently overseeing the design and construction of a new quarantine facility for the gardens.
She warns the public of the risks involved in moving plants around - bringing things back from holidays, especially smuggling things in from abroad. Wax candles, a jar of honey, a wooden sculpture also have the potential to become problematic. Campaigns to increase public awareness are timely and Redstone hopes once people understand they will heed the message "as we all share the same planet".
