The Regency to Pym Project (R2P) team in Adelaide has left a positive ecological legacy with the construction of gardens that provide a food source for native butterflies.

The area surrounding the project is highly urbanised and suitable habitat for wildlife is under pressure. The R2P Alliance developed a landscaping solution with an emphasis on making a green corridor along the route by providing generous amounts of landscaping and trees for aesthetics, shading and ecological purposes.

Their solution included the selection of native butterfly-attracting vegetation in five butterfly gardens, two located at the overpass and another three along the road corridor.

Biodiversity awareness was also rolled out as part of a STEM program delivered at local schools. The program included information on the native butterfly species and on the plants and shrubs included in the butterfly gardens.
