“…In our study, V. uliginosum showed a higher NUI than L. palustre, which resulted from greater dry mass production at a similar cost of plant N concentration. According to investigations in Middle Siberia [26], V. uliginosum is a dwarf shrub that dominates the layer over herbs with large canopies, and L. palustre is a tall shrub that has long stems but a small canopy. In their communities, V. uliginosum exists in a low frequency but a large vegetative growth; in contrast, L. palustre usually exists in a high frequency with small individual growth, especially in canopy size.…”

Unguided exploitation has impaired the sustainability of natural resources of agronomic non-wood forest plants from understory boglands in boreal forests. The extreme consequences of plant–soil interplay on medicinal plant communities under continuous interruptions need to be understood to implement strategies which can cope with possible ecological degradation. In this study, co-existing Ledum palustre and Vaccinium uliginosum communities were investigated after a four-year interruption of continuous removal of dominant species in stands at Xing’an Mountain. Nitrogen (N) availability was assessed by above-ground biomass and N content in nondominant plants and the biophysiological properties of rhizosphere soil. The removal treatment promoted soil mineral and organic N contents, but also reduced abundances of the soil communities of Rozellomycota phylum (by 82.76%), ericoid mycorrhiza of Meliniomyces varia (by 81.60%) and Phialocephala fort (by 69.54%). Vaccinium uliginosum overcame L. palustre through higher N utilization (biomass/%N) although the latter had higher abundances of soil Odiodendron maius and P. fort. The microbial community attributes accounted for a large proportion of N availability following the removal of dominance. In conclusion, our study demonstrates that understory agronomic plants in northern boglands should no longer be under continuous exploitation. Strategies should be considered to improve the promotion of N uptake by managing local soil microbial communities.

“…Habitats of co-existing V. uliginosum and L. palustre communities are mostly concentrated in boreal forests [12,[25][26][27] where soils are apt to suffer low N availability caused by permafrost [16]. Nitrogen is a key element that is heavily needed by NWFP plants [28][29][30] and their co-existing communities [31][32][33][34].…”
