Large scale diversity and distribution of ectomycorrhizal fungi
Research Status:current
This research aims to understand the large-scale diversity and distribution of ectomycorrhizal fungi and how they drive biogeochemical processes and responses to environmental change. 137 level II plots of ICP Forests were sampled across Europe. The effects of pollution and changes in forest soil quality have been closely monitored since the 1980s. The effects of host, environment, climate and geographical variables on ectomycorrhizal diversity have been determined, and thresholds of community change defined for key variables. Host specificity was quantified along with plasticity in functional traits involved in soil foraging across gradients.
Key findings include:
It is planned to conduct another Europe-wide survey of Beech and Pine ectomycorrhizas and re-sample selected ICP Forests plots that were already sampled in 2013-2015. The aim of this survey is to understand how changing environmental variables influence ECM communities over time. To capture the influence of environmental change, selected ICP Forests plots will include plots where key environmental variables increased, decreased and where these stayed the same within the previous 5-7 years.
Forest Research is involved in the sampling of ectomycorrhizal fungi at 8 level II plots and provides long-term monitoring results of host, environment, soil and climate variables through the ICP Forests database.

This research was funded by the Natural Environment Research Council (NERC; grant NE/K006339/1) awarded to Martin Bidartondo (Imperial College London and RBG Kew) and David Orme (Imperial College London). Additional funding is currently being sought to continue this research and progress from the baseline that has now been set, this would enable us to investigate temporal changes of ectomycorrhizal fungi over large geographical scales.
This project is co-ordinated by Imperial College London and Royal Botanic Gardens, Kew and brings together partners from the ICP Forests programme including institutes from 20 European countries
