In September, Catlins Coast Inc launched the ''Adopt the Southern Scenic Route'' project to help keep the 115km stretch through the Catlins litter-free and approached community groups to care for their local 5km section.
Projects co-ordinator Kim Dodds said most of the 100km section of the popular tourist route had been adopted and organised clean-ups were arranged. Catlins Coast Inc had been working with Catlins communities for the past eight years to clean up roadsides.
About 150,000 visitors travelled through the Catlins on the highway each year, she said.
''There has been an improvement over the years. However, we needed more consistency with our clean-ups and better buy-in from our residents. Wow - this initiative is actually working.''
She said more than 100km of the Southern Scenic Route was through the Catlins, and litter had become a ''major problem''.
''It detracts from our region's natural beauty.''
Under the programme, concerned citizens could become involved in improving the environment.
''We were overwhelmed with the support and response from the organisations approached. We were also very pleased with the support we have received from our key partners, with Southland District Council donating $800 to purchase hi-viz vests,'' Mrs Dodds said.
So far Telford, The Catlins Area School, Owaka Going Forward, Pounawea Project Group, Catlins Promotions, Owaka Lions, Catlins Historical Society, PADCA, South Catlins Promotions, Catlins Coast Incorporated, Toetoes Lions and Tokanui School are involved with the project.
''We are extremely lucky to have such proactive community groups in the Catlins,'' Mrs Dodds said. Some residents who walked daily often picked up rubbish and groups and families already co-ordinated their own beach clean-ups.
Mrs Dodds hopes other groups across Clutha will follow suit and get rid of litter in their communities.
