“…Acorn production is influenced by a number of biotic and abiotic factors (Reif & Gärtner 2007, Van Ginkel et al 2013). Animal predation can strongly lower the density of acorns (Kelly 2002, Gómez 2003, Bobiec et al 2011, as corroborated by the results of our study. Acorns are very attractive food preferred by many species (e.g.…”

(1) Sessile oak (Quercus petraea (Matt.) Liebl.) is one of the most important commercial species cultivated at low altitudes in the Czech Republic, and overaged coppices are a significant part of oak stands in the region. In order to secure a high-valuable timber production (e.g., through conversion of such stands into coppices-with-standards), knowledge of the potential and limits of generative regeneration is essential. This study was conducted in three oakdominated over-aged coppice stands in different stages of conversion into coppices-with-standards and characterized by different basal area (BA, from 9.3 to 14.1 m 2 ha -1 ) and relative diffuse radiation (ISF, from 12.1 to 35.5%). The study stands were compared with respect to seed predation following acorn fall and oak regeneration parameters. At the time of their fall the acorns represented a sought-after source of food for large mammals (particularly wild boar). At the end of acorn fall, 13-67% acorns were lost due to animal predation. A control evaluation conducted the following spring revealed a decrease of 92-97% in fallen acorns. Despite the major animal impact, a high reserve of acorns and saplings remained in the stands (4 600-29 000 acorns and 66 000-310 000 saplings per ha). With increasing light intensity the oak regeneration density decreased, while the height and age variability of oak regeneration increased. Although saplings were capable of surviving several years under unfavorable light conditions (even below 12% ISF), they require a minimum of 20% ISF (i.e., BA < 16 m 2 ha -1 ) to achieve sustainable height increment. Based on our results, for conversion of such stands into coppices-with-standards we recommend a maximum of 200 reserved trees (BA = 16 m 2 ha -1 ) to achieve successful height growth of the understorey.

“…However, the success of natural regeneration is conditioned by a number of biotic and abiotic factors (Van Ginkel et al 2013), in particular the climatic conditions (Pérez-Ramos et al 2010), stand structure (Nopp-Mayr et al 2012), seed predation (Focardi et al 2000) or annual shoot browsing (Bobiec et al 2011, Jensen et al 2012.…”

“…This conclusion is in accordance with the several other authors' findings from North American (Pallardy et al 1988, Shotola et al 1992, Mikan et al 1994, Abrams et al 1997, McCarthy et al 2001, Hart et al 2012) and from European oak forests (Bobiec et al 2011, Petritan et al 2014. In a relatively dry North American Quercus alba L. dominated site, a detailed dendroecological study proved that the majority of oak individuals reached the canopy by subsequent releases of stand-wide disturbances, like wind and ice storms (Hart et al 2012).…”

1. The shift from shade-intolerant species to shade-tolerant mesophytic species in deciduous and mixed forests of the temperate zone is well described in studies from North America. This process has been termed mesophication and it has been linked to changes in fire regime. Fire suppression results in the cessation of establishment of heliophytic, fire-dependent tree species such as oak (Quercus) and pine (Pinus). Due to the scarcity of old-growth forests in Europe, data on long-term compositional changes in mixed forests are very limited, as is the number of studies exploring whether fire played a role in shaping the dynamics.2. The aim of this study was to reconstruct tree succession in a 43-ha natural mixed deciduous forest stand in Białowieża Forest (BF), Poland using dendrochronological methods. In addition, the presence of aboveground fire legacies (charred and fire-scarred deadwood) enabled the fire history reconstruction. 3. Dendrochronological data revealed tree establishment (Quercus) back to the end of the 1500s and fires back to 1659. Under a regime of frequent fires until the end of the 18th century, only oak and pine regenerated, sporadically. A shift in the fire regime in the first half of the 19th century triggered oak and pine cohort regeneration, then gradually spruce (Picea) encroached. Under an increasingly dense canopy and less flammable conditions, regeneration of shade-tolerant Carpinus, Tilia,and Acer began simultaneously with the cessation of oak and pine recruitment. Synthesis. The study reports the first evidence of mesophication in temperateEurope and proves that fire was involved in shaping the long-term dynamics of mixed deciduous forest ecosystems. Our data suggest that fire exclusion promoted a gradual recruitment of fire-sensitive, shade-tolerant species that inhibited the regeneration of oak and pine in BF.
