Tree demographic rates were calculated from two forest censuses conducted over a 10-year interval (2010–2020), including recruitment rate [based on newly recorded individuals with diameter at breast height (DBH) ≥ 1 cm], mortality rate, juvenile (DBH &lt; 10 cm) and adult (DBH ≥ 10 cm) abundance growth rates. We analyzed the effects of both biotic (e.g., soil pathogenic and mycorrhizal fungi) and abiotic factors (e.g., soil physicochemical properties and topographic features) on tree demography.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;During the period from 2010 to 2020, the recruitment rate was found to exceed the mortality rate, while the juvenile growth rate was higher than the adult growth rate. Community composition of soil fungal pathogens, but not mycorrhizal fungi, exhibited significant associations with tree demography. These pathogens were negatively correlated with recruitment and juvenile growth rates, while positively correlated with mortality and adult growth rates. In contrast, fungal community stability was positively associated with recruitment and juvenile growth rates but negatively associated with the mortality rate.
