“…Generally, it could be concluded that crown structure of trees develops as a result of the long-term interactions between tree ontogenesis, growth conditions and disturbances that cause defoliation, damage, dieback etc. (Ishii et al 2000). The decline of LAI could go in consequence of two phenomena: 1) decreasing density of live branches and the increasing density of dead branches (Ishii, Wilson 2001) and 2) decreasing production of needles and branches caused by low light, allocation of carbon and nitrogen following to reproductive onset (Thomas, Ickes 1995, Leal, Thomas 2003.…”

“…Therefore, the inverse of the mean life span of foliage is not an appropriate estimate for needle turnover in terms of biomass (Muukkonen 2005). The life span, death and growth patterns of branches were examined to maximize wood quality (Kellomäki and Tuimala 1981, Madgwick et al 1986, Kellomäki and Väisanen 1988, Maguire 1994, Mäkinen 1999, Mäkinen and Colin 1999, Ishii et al 2000, Mäkinen et al 2002, Mäkela and Mäkinen 2003, Mäkinen et al 2003. However, very little is known of the litterfall of large branches, except for the few studies that have proposed alternative approaches, such as branch mortality dating by Maguire (1994).…”
