“…The references found in the specific literature with respect to annual amount of litterfall in Ombrophilous Dense Forest vary according to forest formation, ranging from 5.4 to 12.2 Mg ha -1 yr -1 in Submontane Ombrophilous Dense Forest (ARAÚJO et al, 2006;DICKOW et al, 2012;BIANCHIN et al, 2016;SLOBODA et al, 2017), from 4.9 to 5.6 Mg ha -1 yr -1 in Montane (GOMES et al, 2010;FREIRE et al, 2014), and from 6.1 to 7.1 Mg ha -1 yr -1 in Mixed Ombrophilous Forest (FIGUEIREDO FILHO et al, 2005;ANTONELI;THOMAZ, 2012;SANQUETTA et al, 2016). In studies carried out in old-grown forests in the north coast of Parana state, litterfall was estimated at 8.4 Mg ha -1 yr -1 (SLOBODA et al, 2017), and in advanced secondary forests in the southern region of Santa Catarina at 7.5 to 10.55 Mg ha -1 yr -1 (CITADINI-ZANETTE, 1995;SANTOS, 1997;ROSSO, 2011), being close to that sampled in AR in the present study, with 8.13 Mg ha -1 yr -1 . The results of the study of litterfall in the south of Santa Catarina showed that there is a marked deposition in the months of October and November for the primary forest fragment (CITADINI-ZANETTE, 1995;SANTOS, 1997).…”
