An important issue affecting the Orauea River catchment is the presence of a significant amount of mudstone rock, which is highly unusual for Southland.
To help understand the landscape, this project looks to provide land-users with information on mudstone-based geology and soils and to explain how the interaction between mudstone and water affects water quality. The project will aim to help with managing sediment and E. coli, giving land-users information and confidence to mitigate losses.
Land & Water Science will be engaged to complete a high-resolution stock take of environmental data and map layers, using radiometric and satellite data. Ground truthing will be carried out, mitigation options will be collated into an online resource, and community field days will be held to help share the learnings.
