Abstract

Stream baiting is a useful tool to determine if Phytophthora species are present in a catchment. The method assumes that Phytophthora species accumulate in water bodies and then spread throughout catchments with water movement. However, it is poorly understood how well Phytophthora species accumulate, survive and move within water catchments. This study investigated the ecology of P. cinnamomi collected from seven water bodies within a single mine site. Each water body varied in terms of the organic particulates, dissolved chemicals, water influx and water recycling regimes. Water quality had a significant impact on the sporulation and infection of plant baits by P. cinnamomi in each water body. The findings and implications of stream baiting as a catchment‐level monitoring tool will be discussed.
