Erratum to “Densities of large living and dead trees in old-growth temperate and boreal forests”

Bryophytes and decaying wood in Hepatica site-type boreo-nemoral Pinus sylvestris forests in Southern Estonia

“…Jonsson et al, 2005;Christensen et al, 2005) there are also results which disagree with these facts (Spies et al, 1988;Boudreault et al, 2002;Rubino and McCarthy, 2003). The amount of CWD depends also on tree species content of stands and habitat conditions (Spies et al, 1988;Fridman and Walheim, 2000;Nilsson et al, 2003;Rubino and McCarthy, 2003). However, increase in stand age contributed positively to the amount of large logs (d !…”

Influence of fine woody debris on spider diversity and community structure in forest leaf litter

“…One would not expect to find large amounts of FWD in forests such as the one we studied, because high accumulations of FWD are characteristics of younger forests, in which competitive exclusion and self-thinning dynamics dominate (Peterken 1996). Forests with thicker trees generate more coarse woody debris (Nilsson et al 2003). A corollary of these observations is the prediction that the older the forest, the lower is the amount of FWD expressed as a proportion of all woody debris material (Nordén et al 2004a).…”

The challenge of combining timber production and biodiversity conservation for long-term ecosystem functioning—A case study of Swedish boreal forestry

“…The rotation period for harvesting timber Table 1 Indicator categories and corresponding targets in the Swedish national objective Healthy Forests (Miljödepartementet, 2001) and requirements in the FSC standard (Anon., 2000), respectively Old-growth/older trees Increase area of old-growth forest with 5% Set aside age-differentiated, multi-cohort areas from forestry Leave at least 10 storm resistant trees at logging is too short for functions and structures that characterize biologically old forests to develop, for example, stem hallows, exposed dead wood, sap-flows, dead branches and dead tops (Foster et al, 1998;Niemelä, 1999;Schroeder and Perea, 2002;Nilsson et al, 2003;Turner et al, 2003). In a study by Berg et al (1994), compiling present knowledge on threatened species in Sweden, it was concluded that habitat associations and distribution patterns were roughly the same for all threatened organism groups.…”
