Multiple studies demonstrate that dead wood is a crucial component of forest ecosystems, providing vital habitats and carbon storage that directly support high levels of biodiversity, including saproxylic insects, fungi, and birds.
The retrieved papers consistently emphasize the ecological importance of dead wood (both standing snags and downed coarse woody debris) in driving biodiversity, supporting saproxylic species, influencing carbon dynamics, and serving as a key structural component in forest management. All relevant papers support the claim, and none contradict it.
