Although little about ECM fungal communities on endangered tree species is known, knowledge of their ECM associations could be a key to conservation given the functional importance of the symbiosis. Methods: We collected 73 soil samples from three relict forests dominated by endangered Chinese Douglas-fir (Pseudotsuga sinensis). Identity of fungal and host species in individual ECM tips was determined by morphotyping and DNA analyses. Results: Of the 86 ECM fungal species identified, 66 were observed on Chinese Douglas-firs. While the fungal composition did not significantly differ between coexisting trees (p = 0.843), the composition was significantly separated based on location (p = 0.021). Moreover, the observed ECM fungal communities were dissimilar to those on the Japanese Douglas-fir (p = 0.001), which is monophyletic to Chinese Douglas-fir. Conclusions: Our results indicate that ECM fungal communities are determined more by geographical location than host monophyly on this spatial (c.770-1,600km) and geological time scale ( c. 20-25 My). For conservation of endangered trees, it may be important to preserve local ECM fungal pools, irrespective of host species.
