Summary of "Nature and Cultural Heritage | How to Conserve These Sources of Inspiration"
Scientific Concepts, Discoveries, and Nature Phenomena Presented
- Heritage and Conservation Concepts:
- Heritage defined by UNESCO as a legacy from the past, encompassing both cultural and natural heritage, which are irreplaceable sources of life and inspiration.
- Conservation involves managing change in significant places to sustain, reveal, or reinforce cultural and natural heritage values.
- The interrelationship between landscape (physical environment), nature (biological elements), and culture (human activities and artifacts) forms a system affected by environmental change.
- Conservation aims to improve resilience of these interconnected systems.
- Research Focus and Methodology (OxRUBBLE Lab):
- Interdisciplinary approach including geographers, archaeologists, conservation scientists, chemists, engineers, and architects.
- Three broad research strands:
- Learning from past conservation practices.
- Biogeomorphology: interaction between rocks and living organisms.
- Working with nature to better conserve cultural heritage.
- Use of long-term, interdisciplinary studies to understand friend/foe roles of nature in heritage conservation.
- Integration of Nature and Culture in Conservation:
- Nature can be both a friend (bioprotection) and foe (biodeterioration) to cultural heritage.
- Culture can be both a friend (providing habitats for species) and foe (restricting natural processes like rewilding) to nature.
- The concept of “Green Conservation” aims to integrate nature and culture for improved resilience and human well-being.
- Nature-based solutions (e.g., reintroduction of beavers) can benefit both natural and cultural heritage.
- Hierarchy of Conservation Focus:
- Biodiversity (biological diversity)
- Cultural diversity
- Geodiversity (diversity of geological features)
- Conservation areas include geoparks, nature reserves, and cultural sites.
- Policy Developments:
- National Trust’s new strategy emphasizes the need for both nature (survival) and culture (identity and connection).
- English Heritage’s 2023 sustainable conservation principles include integrating nature for the benefit of natural and historic environments.
- Collaborative statements by Natural England, Historic England, and National Lottery Heritage Fund highlight integrated management of natural and historic environments.
- Case Studies Illustrating Nature-Culture Interactions:
- Lichens on Cultural Heritage:
- Lichens can cause biodeterioration but also provide bioprotection.
- Cultural heritage sites provide unique habitats for lichens.
- Example: Rock art in the Côa Valley, Portugal, where lichens and microbes colonize carved schist surfaces.
- Use of digital twins and photogrammetry to monitor changes without touching the rock art.
- Grasses and Small Plants on Ruins:
- Plants like sedums and grasses colonize ruined walls, potentially protecting masonry by reducing water ingress.
- “Soft” or “natural” wall capping uses vegetation to protect wall heads.
- Example: Hailes Abbey, where turf and sedums have been used successfully.
- Climate change poses challenges to the effectiveness of natural capping.
- Trees and Woody Plants on Cultural Heritage:
- Trees can damage ruins with root systems but also create microclimates that protect stonework.
- Example: Angkor Wat, Cambodia, where removal of trees led to increased deterioration from microbes.
- The famous “root-covered” ruins (e.g., Ta Prohm) represent a novel heritage form blending nature and culture.
- Mixed Heritage Sites:
- Sites like the Lake District combine extensive natural and cultural heritage.
- The SYN network studies sites at the intersection of natural and cultural heritage globally, promoting interdisciplinary research and management.
- Lichens on Cultural Heritage:
- Challenges and Opportunities:
- Balancing conservation of nature and culture, especially where they may conflict.
- Need for interdisciplinary, long-term research to understand complex interactions.
- Potential for nature-based solutions to improve resilience and human well-being.
- The concept of “Green Conservation” as a middle ground between fully managed cultural sites and wild natural sites.
