There are three major creeks that flow through the catchment across farmland and discharge into the Waituna Lagoon. These creeks are named the Waituna Creek, Moffat Creek and Currans Creek (Baines, 2015, para 1). In 1976 the Waituna Lagoon and surrounding wetlands were designated under the RAMSAR Convention as being of International Significance. Water quality in the Waituna Catchment is poor due to high levels of suspended sediment and nutrients as a result of increasing agricultural development (Environment Southland, 2012, p1). One of the solutions to achieving sustainable land use for improved water quality is to harness the abilities of riparian zones. Riparian zones absorb excess nutrients and process waste minerals before they enter waterways (Collier et al., 1995, p 4). Below is a map showing the location of the Waituna Catchment (Figure 1). SITJAR 2019 | Special Edition – Environmental Publications 6 Map of Waituna Catchment Figure 1. Waituna Catchment Map. Black outline denotes the boundary of the catchment AIM The aim of this study was to determine the knowledge and application of riparian planting by dairy farmers in the Waituna Catchment. METHODS This research adopted two methods to achieve the aim: Qualitative Method – Phone Surveys Quantitative Method - Vegetation Surveys Phone Survey A survey was created with both open and closed questions for the participants to respond. Contact details for 12 possible participants were collected, and subsequently called to ask if they would like to participate in a 10-minute survey. Once the survey was completed, all participants were asked for permission to undertake a vegetation survey on their property (Please see Appendix A for a copy of the survey questions). A total of 10 out of the 12 possible participants decided to participate in the phone survey. SITJAR 2019 | Special Edition – Environmental Publications 7 Vegetation Survey Six vegetation surveys were undertaken, and the locations of these surveys
