Structure of this Report This Heritage Assessment is Phase 1 of a 2 part study process which has been designed to assess the heritage values of the Lake Burley Griffin Study Area and, should Commonwealth and National Heritage values be found to be present, prepare a Management Plan for the place (Phase 2) as required under the EPBC Act. The sections of this Heritage Assessment aim to build up a detailed picture of the natural and cultural landscape of the study area, revealing its different layers of heritage values. The structure of the assessment is as follows: Section 1.0—Introduction Section 2.0—Setting the Scene Introduces the features and elements of the Lake Burley Griffin Study Area, as well as the foreshore areas and surrounding landscape, which although outside the formal boundary of the study area, constitute the landscape context of the lake and are vital to an understanding of the place. Section 3.0—The Environmental Context Explains the environmental context of the Lake Burley Griffin Study Area, particularly focusing on the ‘pre-lake’ environment. The evolution of the landscape through geological time is described, as is the vegetation which covered the pre-settlement landscape. This description of the environmental setting of Lake Burley Griffin and its foreshores will allow comparisons (in later sections) between its present form and its earlier natural state, and provide a clearer picture of how the current landscape, environment and natural values evolved. Section 4.0—The Indigenous Cultural Landscape Reviews the evidence for the Aboriginal occupation of the Lake Burley Griffin Study Area in its broader regional context. It explores the meanings and values attributed to the landscape by Indigenous communities both in the past and contemporaneously. It also discusses previous archaeological research and the results of field surveys carried out for this heritage assessment. Section 5.0—The Historical Context Charts the historical evolution of the lake within the social and political context of the development of the national capital, Canberra. Section 6.0—The Designed Landscape Focuses on Lake Burley Griffin as a key component of the designed landscape conceived by Walter Burley Griffin and Marion Mahony Griffin, and the way in which the landscape has evolved to reflect changes in society, changes in design philosophy and changes in the notion of the Australian nation and Australian national identity. Section 7.0—Community Attachment and Values Reports on the nature and scope of the values held by communities for the Lake Burley Griffin Study Area. Lake Burley Griffin—Heritage Assessment—Final Report, October 2009 v Section 8.0—Layers of Value Draws together the threads of the research presented thus far, and also introduces additional data to flesh out a detailed picture of the Lake Burley Griffin Study Area as a complex cultural landscape with many layers of value. The values of the lake as an ecosystem are first presented, followed by a synthesis of the layers of history present in the study area, with a particular focus on the lake as an engineering achievement, as well as a visual analysis of the study area. Section 9.0—Assessment of Heritage Values Presents the results of the research included in the previous sections and analyses the findings in terms of the EPBC Act criteria. It also considers whether the threshold for Commonwealth or National Heritage value is met for each criteria, provides a summary statement of values and a table of values and attributes. vi Lake Burley Griffin—Heritage Assessment—Final Report, October 2009
