Environmental impacts The prolonged and intense rainfall in the upper catchment, and the resultant major flooding, have had very significant environmental impacts across the entire LGA.
Due to their scale and complexity thorough assessment of these impacts is a huge task, and it is not possible at this stage to precisely quantify them.
The volume and velocity of water coming down the creeks and into the Wilsons and Richmond Rivers has caused significant erosion of banks, as well as damage to riparian vegetation. This includes riparian vegetation that had previously been restored with both public and private funds and countless volunteer hours. Exposed banks are now vulnerable to continued accelerated erosion which may also cause further sedimentation of waterways.
Lismore City Council’s Environmental Strategies Team has commenced assessment of impacts on riparian vegetation and other high conservation value vegetation in the CBD and urban bushland reserves. We have reached out to current and past partners of the Rural Landholder Initiative to understand the impacts on their habitat restoration Other areas of vegetation, including revegetated projects, and on the rural environment generally. and restored habitat, have also been affected by floodwaters. Prolonged inundation, foliage coated Landslips have been reported from across the by mud and pollutants, and the impact of high upper catchment, ranging from small-scale to velocity water and flood debris are all causes of very significant. As well as damage to homes and loss of or damage to vegetation. infrastructure, these landslips have caused loss of soil and vegetation, and continue to be a source of sedimentation of creeks and the river.
