Dr. Sandy Pollock will present on the history and rationale for the Weed Spotters Network of Queensland, an organisation that leans heavily on citizen science for weed surveillance across Queensland.  Invasive plant control is wholly reliant on early detection of problematic species, and the WSNQ provides a means to collate and coordinate this across the state.  He will also outline how this is relevant to the Brisbane and Mount Coot-tha districts.

Alexander (Sandy) Pollock has a long history of botanical investigation.  He studied botany at the University of New England in Armidale, NSW, and was employed as a botanist in East Gippsland (Victoria), a QPWS ranger in central Queensland in Mackay and finally as a senior botanist and vegetation mapper at the Queensland Herbarium.  These broad experiences in plants and their habitats continues to this day, and Sandy finds the curiosity and thrill of encountering new plants never fades.

Sandy brings extensive skills and experiences on plant knowledge and community engagement to the Weed Spotter Network Queensland project, having worked on the Plant Identification Service in the Queensland Herbarium since 1997, helping the public with their plant queries.  Previously he was involved in control measures for the WONS weeds rubber vine and Parkinsonia while a QPWS ranger.
