High-resolution genomic analysis to investigate the impact of the invasive brushtail possum (Trichosurus vulpecula) and other wildlife on microbial water quality assessments
Escherichia coli are routine indicators of fecal contamination in water quality assessments. Contrary to livestock and human activities, brushtail possums (Trichosurus vulpecula), common invasive marsupials in…

Monitoring to detect changes in water quality to meet policy objectives
Detecting change in water quality is key to providing evidence of progress towards meeting water quality objectives. A key measure for detecting change is statistical…
Summary
More Investment in Water Quality Monitoring is Needed
Aotearoa will not know if our water quality is improving for another 20 years unless we make a large investment in our water quality monitoring…
