Description

Fungi play important roles in forest restoration, but factors affecting fungal species composition and distribution are unknown for restoration associated with dam removal. The need for this information is becoming acute as the number of dams approaching the end of their useful lives grows rapidly. We aim to answer what environmental factors influence fungal distribution in the Elwha restoration ecosystem, the largest dam removal in history. We sampled fungal distributions in two Elwha study areas: the largest former reservoir bed and a comparable valley upriver from both dams and reservoirs. In each study area, we conducted a stratified random sample of fungal distributions and relative conditions of vegetation and substrate. We defined strata by stage of forest development: recent sediment deposits, young forest, and mature forest. We fit fungal distribution data site factors using information theoretic methods. Our results can be applied to forecast future fungal distributions as Elwha restoration proceeds, and inform decisions about dam removal on other river basins to enhance restoration outcomes.

Fungal distribution in the Elwha restoration ecosystem
