Woodland ectomycorrhizal fungi benefit from large-scale reduction in nitrogen deposition in the Netherlands

摘要

1. Woodland ectomycorrhizal (ECM) fungal species declined considerably in the Netherlands in the late 20th century, mainly due to raised levels of atmospheric nitrogen deposition. Environmental measures have been taken to reduce this deposition, but it remains unclear whether and to what extent ECM species have benefitted from these.
