“…It is one of the most relevant components of forest biodiversity, and it represents an important forest carbon pool (Stokland et al 2004, Woodall et al 2009). Dead trees, stumps, and fine and coarse woody debris (CWD) are essential to forest ecosystem dynamics by providing food and habitat for taxa such as fungi, arthropods, birds, insects, and epiphytic lichens (Sippola and Renvall 1999, Bowman et al 2000, Ferris et al 2000, Siitonen et al 2000, Similä et al 2003, Jonsson et al 2005, Odor et al 2006, Londsale et al 2008, Winter and Möller 2008. Approximately 20 -25% of forest species depend on decaying wood (Boddy 2001, Siitonen 2001, although decayed material is often viewed as a limited habitat resource for some organisms (Hagen and Grove 1999).…”
