Abstract
This project examines long-term climatic and landscape evolution in a critical area of Ireland’s archaeological heritage, the World Heritage Site (WHS) at Brú na Bóinne, Co. Meath. The project will explore the nature of cultural activity in the landscape over the Mesolithic and Neolithic periods, through a focus on landscape and land-use reconstruction using environmental archaeological approaches. The project is multidisciplinary in that it incorporates elements of archaeology, physical geography and climate change science, and addresses a key site in Ireland’s archaeological heritage with a focus on a critical stage in the development of the Brú na Bóinne landscape, and the adoption of agriculture.
This research will allow the reconstruction of both the palaeoenvironment and palaeoclimate of the region, and so for the first time place the WHS within a sound environmental and climatic context. This area is vitally important for models of Mesolithic and Neolithic cultural change in relation to changing environments in northwest Europe, and the development of a palaeoenvironmental model will allow greater comparability to other important landscapes in a broader European context.
Key Research Questions
In developing a detailed palaeoenvironmental framework for the region this proposal will help address a number of key research objectives of the WHS Research Framework, Consultation Document (Heritage Council 2008):
- When did people first come to the Brú na Bóinne landscape and what was the nature of this first presence?
- What was the nature of the activity in Brú na Bóinne during the later Mesolithic?
- When did the transition to farming take place in Brú na Bóinne and how is it characterised?
- How did the builders of the Brú na Bóinne Neolithic passage-tomb complex use their landscape?
Additionally the methodology will allow the construction of a palaeoclimatic framework, highlighted as a key research priority in better understanding the adoption of agriculture in Ireland in early prehistory (Warren 2008).
Methodology
- Targeted high-resolution pollen analysis, informed by radiocarbon dates, to provide a number of complimentary records of landscape evolution at critical time points throughout the area of the WHS.
- Loss-on-ignition analysis.
- Pollen-based landscape modelling.
- Analysis of chironomid (non-biting midge) head capsules will be undertaken in order to provide a Holocene climate record from the area (in collaboration with Dr. Naomi Holmes, a postdoctoral researcher within UCD School of Archaeology).
- The Itrax Core Scanner facility within UCD School of Geography Planning and Environmental Policy (under the direction of Dr. Jonathan Turner). The Itrax has a number of potential uses including locating potentially datable tephra horizons within lake deposits in addition to the location of possible early indicators of agricultural activity within the Brú na Bóinne region.
