This thesis develops andpreliminarily tests abiophilic adhesive filler forthe fossilized tree stumps at Florissant Fossil Beds National Monument (FLFO), whichare rapidly deteriorating due to the impacts of precipitation and freeze-thaw cycling. At the crownof Stump P47, lichens have been observed to have a consolidating effect,preventing further fragmentation. Recent conservation research confirmsthat in certain environments, with specific substrates and organisms, microflora and macroflora can act as protective and consolidating agents for stone substrates. This thesis explores these benefits by considering potential materials for the formulation of a biophilic adhesive filler, which could be used as a protectivesurface treatment on the FLFO stumps. The adhesive fillerfor open cracks and fissurescould offer temporary protection, consolidation, waterproofing, and abioreceptiveand nutrient-rich surface onwhich lichens may continue to flourish. In order to develop the surface treatment, optimal performance characteristics were established. Materials wereresearched and selected based on their adherence to these characteristics, then preliminarily tested for their properties individually and in combination with other materials as composite systems. Qualitative observations determined which formulations met the outlined characteristics, and recommendations for future confirmatory testing aremade.This thesis suggests an innovative direction for future research for cultural heritage protection.
