Here we use a correlative approach to link the community of soil protists with fallen wood at different decomposition stage and compare with fallen-wood-free soil. The indicators of protists community were assessed using DNA metabarcoding of the 18S rRNA (Illumina sequencing).</p><h3 data-test=\"abstract-sub-heading\">Results</h3><p>The biodiversity of soil protists tended to increase as decomposition advanced and pronounced difference was found between severe and moderate decomposition stages (<i>P</i> &lt; 0.05). The decomposition of fallen wood had a significant effect on the composition of the soil protist community (Adonis: R² = 0.24, <i>P</i> &lt; 0.01), and enhanced the complexity and stability of the co-occurrence network of soil protists. Soil protists exhibited a stronger association with fallen wood (11 significant linkages), compared to soil (7 significant linkages). Fallen wood decomposition indirectly affected the soil protist community through multiple ways.</p><h3 data-test=\"abstract-sub-heading\">Conclusions</h3><p>Retention of fallen wood helps maintain the richness and interaction of soil protists.
