High density: 1.5 m 2 m; low density: 1.5 m 4 m.In line with Tables 3 and S2, the niche overlap of dominant shrubs in the patterns of diverse compositions and densities may be obtained (Table 4), and also the diversity of shrubs is higher in the patterns with decrease niche overlap of dominant shrubs. By way of example, theForests 2021, 12,9 ofoverlap of dominant shrubs in high-density pure forests is reduce than that of low-density pure forests, and also the overlaps of dominant shrubs within the Cf pattern would be the highest, whilst the overlap of dominant shrubs within the two mixed tree species patterns is reduced than that of pure forests and also the three tree species mixed with the same density, which can be opposite for the distribution of shrub diversity in each model.Table four.

Discussion For plantations with poor tree diversity, understory vegetation is an crucial a part of the diversity of your entire plantation, offering a habitat and food for a lot of organisms, promoting nutrient cycling, stopping erosion, and affecting seed germination andForests 2021, 12,ten ofseedlings in the forest ecosystem with regard to survival and growth [22]. In this study, we carried out unique patterns of cypress forest transformation, and studied and revealed the diversity of understory shrubs in stands with diverse tree compositions and density along with the partnership amongst their shrub niches. The results showed that the tree composition and density had a substantial influence on the diversity of shrubs, and that the niche is closely associated to the diversity of shrubs. In each and every transformation pattern, the overlap on the niche with the shrub diversity as well as the dom.
