In March the PHCC Hotham-Williams Team and Wetland Research and Management carried out the autumn river health assessment sampling for the #HothamWilliams Rivers and a draft report has been received and is under review.
The draft report summarises the findings in the field, which covered a comprehensive set of ecological parameters including a survey of fish, crayfish and macroinvertebrate communities, along with instream habitat condition and water quality measurements.
Three of the six sampling sites offered up a total of 46 snake-necked turtles over both sampling events in spring 2019 and autumn 2020. Chelodina colliei is endemic to the south-west of WA and is listed on the International Union for Conservation of Nature (IUCN) Redlist of Threatened Species as Near Threatened. They are known to occur in both permanent and seasonal habitats and can travel overland if local conditions are not favourable. These turtles only eat when open water is present because their diet includes tadpoles, fish, and aquatic invertebrates. The main threats to their survival is a drying climate, road deaths during movement in the nesting season and predation by feral animals.
This project is made possible through funding from Newmont Boddington and the Department of Water and Environmental Regulation.
