ABSTRACT
The genus Phytophthora is a serious plant pathogen that can infect and kill a range of tree species. Phytophthora cinnamomi is identified as a Key Threatening Process under the NSW Biodiversity Conservation Act (2016) and the Environment Protection and Biodiversity Conservation Act (2019), and exotic species pose a threat to horticultural production. Phytophthora is a significant threat to urban forests but its extent has not yet been well documented. Matthew will present the results of a pilot study which investigated the occurrence and diversity of Phytophthora species in urban tree planting stock and will discuss measures which can be adopted by practitioners in nursery and urban forest management to manage this risk.
