Flora and Fauna management

Vegetation management

The Regency Road to Pym Street Project has been carefully designed and staged to maintain existing vegetation wherever possible. Road design and construction methodologies have been planned to maintain as much vegetation as possible.

The project will plant more than 512 new trees, as well as 43,603 bushes, grasses and groundcovers. The R2P Alliance has also investigated opportunities to enhance amenity and create positive habitat outcomes across the project footprint, including butterfly gardens.

Vegetation removals started in October 2019.

Selecting species

The landscape design will balance the use of indigenous and non-indigenous species and include semi-mature trees to help offset the loss of mature vegetation. Species selection will adhere to safety standards for proximity to the motorway.

The list of trees to be planted has been developed with The Department for Infrastructure and Transport, The Office for Design and Architecture South Australia (ODASA) and the City of Port Adelaide Enfield.

For more information on plant species selected for the project please visit the Landscape and Urban Design page.

Managing removals

Removal of vegetation was carefully supervised by a fauna specialist and an arborist. All trees were inspected prior to removal, and if fauna was found, they were relocated by professionals.

Reusing limbs and trunks

Fallen limbs play an important part in local biodiversity. Large limbs and trunks removed as part of the project are retained to be placed in parks and reserves where practically possible. Trunks will be installed in playgrounds to provide nature play opportunities. The R2P project team identified the opportunity to provide tree logs for reuse to the Preschool at St Joseph’s School, Ottoway. The logs were used to refresh the outdoor area with a nature play theme. The remainder of the removed vegetative material will be mulched and used in landscaping.

Community Wildlife Program

The Community Wildlife Program is a Department for Infrastructure and Transport initiative that involves local communities and schools in helping to offset the loss of habitat caused by necessary vegetation removals.

The R2P Project team is working with local schools and community members to learn about the important role of biodiversity and planting butterfly gardens to try and help increase their currently declining numbers. We are working with local schools to explore how we can work together to improve biodiversity in the local area.

In particular, we are working closely with local schools and community groups to provide butterfly garden workshops, and information about how to attract butterflies and other wildlife into the local area and residents’ back yards.

Local school wildlife workshops involve the community in helping to enhance local habitat.

Community wildlife packs

The Community Wildlife Project is a R2P Project initiative to encourage the community to help maintain native habitat in urban environments.

Reduction in floral diversity results in lower numbers of wildlife species. This is why the R2P Project is raising awareness of how the community can contribute to the enhancement of local biodiversity.

The R2P project team has developed a tailored landscaping package focusing on increasing the quantity and variety of native plants, to enhance local biodiversity. This is achieved by including pockets of butterfly-attracting vegetation.

These pocket butterfly gardens complement the Community Wildlife Project that was delivered to four local schools during June 2020, where butterfly gardens were also planted.

Community wildlife packs are being offered to residents to encourage native planting within the neighbourhood to help increase biodiversity.

The packs contain butterfly-attracting seeds, information on how to germinate, planting and care for the plants and a list of local resources and environmental organisations.

Packs will be available upon request to residents and businesses within the R2P Project area. Registrations close on Friday, 6 August 2021, after which the project team will contact you to coordinate the delivery of your pack.

To register, please email the team at or call 1300 910 533. Your name, phone number and property address will be required.
