ABSTRACT

This paper serves to highlight the observed impacts of the Stormwater Network on the spread of weedy species in the streams and bush areas of North Shore City. The observations made during the course of the 2-year “Stream-walk” and survey, undertaken in 2002-2004, support the conclusions and suggested remedial actions presented.

Activities associated with the stormwater and infrastructure networks have the potential to exacerbate the rate of spread of invasive weed species. It became clearly apparent during the “Stream-walk” survey that there was a strong relationship between the network and the distribution of weedy species
