Project Title 

Moss on Rocks’: Evaluating biodeterioration and bioprotection of bryophitic growth on stone masonry

Background & Summary of Project

The main aim of this project is to characterize the impacts of moss growth on stone masonry, and to determine if their presence on built structures can be categorized as having either an overall bioprotective or biodeteriorative effect on built structures. Along with investigations of a set of previously weathered limestone blocks, three primary case study sites (Kelmscott Manor, Blenheim Palace, and the Oxford Botanic Gardens) have been carefully chosen to illustrate real-world effects of moss growth on historic buildings. In order to fulfil the main project aim, three primary research questions have been devised to address the different aspects of moss growth on built heritage. 
1.    How do built heritage visitors and experts view the presence of moss growth on historic buildings?
2.    How does moss growth affect the deterioration and weathering processes of stone substrates? 
3.    How does moss growth affect moisture relations on stone substrates?
