executive overview
Wittunga Botanic Garden is a highly valued public asset, managed by the Botanic Gardens of Adelaide
since 1965. Built around the garden structure and plant collections developed by the Ashby family,
Wittunga is a unique display of Australian and South African plant species with direct cultural
connection through their interrelated geographic zones.
The current configuration of the Garden has changed little since its completion in the late 1970’s and
the natural bush settings have matured to provide an engaging experience for visitors. Intensive
horticultural maintenance, previously required within the Garden, is unsustainable in the current and
future climate with new methodologies and innovative practices required to ensure the long term
viability of Wittunga.
This Master Plan reviews the current structure and use of the Garden and provides direction for
sustainable change that will improve accessibility and encourage greater use and appreciation of this
unique resource. Central to the recommendations within the Master Plan is the need to practice and
promote resilient use of climatically suitable plant species, water resources and natural materials.
The commissioning of this Master Plan responds to the aspirations of the Botanic Gardens of Adelaide
and the broader community providing long-term planning for the future of the Garden. Realisation of
key initiatives within the Master Plan will exemplify the cultural and environmental importance of
Wittunga to the community.

Wittunga also has a fascinating history of
perseverance, experimentation and innovation
that adds an important cultural layer to the
Garden and meaning to the local community.

After taking over the Garden in 1965, the period
to 1975 was spent developing and implementing
a garden design for Wittunga in readiness for
opening to the public. Modifications and
improvements have occurred incrementally
since then but a formal master plan for the
Garden has never been set in place.

1.2 structure of the report
process
The Master Plan has been developed through a
detailed program of consultation with the
Botanic Gardens of Adelaide Board,
Management and Staff.
Individual and group meetings have been held
with staff on and off site throughout the master
planning process to gain a thorough
understanding of the unique qualities of
Wittunga.
A Reference Group, comprising a broad range of
stakeholders, has been consulted at formal
meetings and presentations of the Master Plan.
In addition, informal meetings and
correspondence with individual members of the
Group have added depth to the responses and
ensured information has been conveyed.
Draft Master Plan Reports were issued to the
management and staff of the Botanic Gardens of
Adelaide for review and comment and also
distributed to the Reference Group for their
response.
The Master Plan was released electronically on
the Botanic Gardens of Adelaide website for
public consultation and distributed throughout
the community by the Reference Group. The
feedback provided invaluable knowledge and
insight to ensure the Master Plan conclusively
addresses the current and future needs of
Wittunga.
The completed Master Plan provides
considered, sustainable directions for Wittunga
Botanic Garden that will incrementally improve
and define a most-valued cultural asset.
