High density: 1.5 m two m; low density: 1.5 m four m.In accordance with Tables three and S2, the niche overlap of dominant shrubs inside the Inhibitor| patterns of various compositions and densities is often obtained (Table 4), and the diversity of shrubs is higher in the patterns with reduce niche overlap of dominant shrubs. By way of example, theForests 2021, 12,9 ofoverlap of dominant shrubs in high-density pure forests is lower than that of low-density pure forests, plus the overlaps of dominant shrubs in the Cf pattern would be the highest, although the overlap of dominant shrubs in the two mixed tree species patterns is lower than that of pure forests along with the three tree species mixed with the exact same density, which is opposite for the distribution of shrub diversity in every single model.Table four.

Discussion For plantations with poor tree diversity, understory vegetation is definitely an vital part of the diversity with the complete plantation, providing a habitat and food for a lot of organisms, advertising nutrient cycling, preventing erosion, and affecting seed germination andForests 2021, 12,10 ofseedlings in the forest ecosystem with regard to survival and growth [22]. In this study, we carried out distinctive patterns of cypress forest transformation, and studied and revealed the diversity of understory shrubs in stands with distinct tree compositions and density plus the partnership amongst their shrub niches. The results showed that the tree composition and density had a important effect around the diversity of shrubs, and that the niche is closely related for the diversity of shrubs. In every transformation pattern, the overlap of the niche from the shrub diversity and also the dom.
