“…It appears that Wollemi pine seedlings select for a specific root bacterial community independent of the composition of bacterial communities present in soil in the wild (Rigg et al. ).

“…In contrast, Wollemi pine seedlings are limited in terms of the fungal taxa that they are able to associate with based on the soil community they are exposed to (Rigg et al. ). Extensive variation exists in microbial communities across the wild Wollemi pine site that is independent of the identity of the adult tree growing in soil and this also variation has the potential to affect seedling growth (Rigg et al.…”

“…Here, we use a plant‐soil feedback approach to investigate the functional effect of differences observed in the microbial communities associated with Wollemi pine seedlings inoculated with soil collected from under Wollemi pine and neighboring coachwood ( Ceratopetalum apetalum D. Don) in the wild (Rigg et al. ). Specifically, we investigated whether there was a plant–soil feedback effect to test if seedlings of Wollemi pine or coachwood performed better in soil collected from under conspecific adults (Fig.…”

Plant-soil feedback, the reciprocal relationship between a plant and its associated microbial communities, has been proposed to be an important driver of plant populations and community dynamics. While rarely considered, understanding how plant-soil feedback contributes to plant rarity may have implications for conservation and management of rare species. Wollemi pine (Wollemia nobilis) is a critically endangered species, of which fewer than 100 trees are known to exist in the wild. Seedling survival within the first year after germination and subsequent recruitment of Wollemi pine is limited in the wild. We used a plant-soil feedback approach to investigate the functional effect of species-specific differences previously observed in the microbial communities underneath adult Wollemi pine and a neighboring species, coachwood (Ceratopetalum apetalum), and also whether additional variation in microbial communities in the wild could impact seedling growth. There was no evidence for seedling growth being affected by tree species associated with soil inocula, suggesting that plant-soil feedbacks are not limiting recruitment in the natural population. However, there was evidence of fungal, but not bacterial, community variation impacting seedling growth independently of plant-soil feedbacks. Chemical (pH) and physical (porosity) soil characteristics were identified as potential drivers of the functional outcomes of these fungal communities. The empirical approach described here may provide opportunities to identify the importance of soil microbes to conservation efforts targeting other rare plant species and is also relevant to understanding the importance of soil microbes and plant-soil feedbacks for plant community dynamics more broadly.
