Previous studies have reported the notable impact of phosphorus on the ‘serpentine debris’ community, and the negligible effect of nitrogen. However, a survey in 2010 provided our first indication that the experimentally-induced phosphorus effect was weakening and this was consolidated by further surveys of vegetation cover and community composition. This community shift might have been different had the local climate acted synergistically with phosphorus additions: in the last few years of the study the Shetland Isles experienced particularly low spring rainfall – the dry spell may have been a well-timed environmental filter driving community recovery rather than a permanent change of state to heathland on an organic soil. The longevity of our investigation is a unique opportunity to explore vegetation response to the key drivers of global environmental change, namely climate change, eutrophication as a result of agricultural intensification, and the potential for invasion of species as new resource-rich niches become available. 2025-04-23 published 10.24377/LJMU.d.00000225 British Ecological Society and Scottish Natural Heritage (contract 17114) Sarah E Dalrymple British Ecological Society and Scottish Natural Heritage (contract 17114) 3103 310302 310899 410102 Field survey of plant communities under a range of control and nutrient addition treatment Scotland, Shetland Isles, Unst English English Access granted by Scottish Natural Heritage 1981 2013 https://doi.org/10.1080/11263504.2019.1701578 2025-04-23
