“…Litterfall per hectare per year for Quercus robur/petraea ranged from 2.5 to 11 kg Mg (Carlisle et al 1966;Christensen 1975;Diaz-Maroto;Vila-Lamerio 2006;Hansen et al 2009). For other oak species (Q. potosina, Q. castaneifolia, Q. rotundifolia, Q. coccifera, Q. humboldtii, Q. variabilis, Q. floribunda, Q. lanuginose) the annual litterfall varied similarly be- Annual litterfall was positively correlated with the mean temperature and negatively correlated with precipitation and P/T ratio, i.e.…”

Litterfall, an important component of the nutrient cycle in forest ecosystems, was measured for 9 years in young oak stands on two localities classified as beech-oak climax (Fageto-Quercetum). We estimated that about 4 Mg of dry mass per hectare fell each year. Nutrient content in the litterfall represents annually per hectare approximately 40-55 kg of nitrogen, 2-3 kg of phosphorus, 7-16 kg of potassium, 41-73 kg of calcium and 6-7 kg of magnesium. The amount of litterfall is positively correlated with stand basal area and with the death of suppressed tress with small crowns. We found a positive correlation between annual litterfall and the sum of precipitation and a negative correlation between annual litterfall and temperature in summer.

“…In addition, seed dispersal is not a problem for oak establishment, as the European jay (Garrulus glandarius L.) transports acorns [32,33]. Oak can also grow on less fertile soils in Latvia [36], as in other parts of Europe [37,38]. In some cases, oak stands also occur on eolian dunes [39].…”

“…Moreover, dense moss and herb vegetation cover might favor the establishment of this species, and also growth, especially for seedlings <50 cm. Oak tolerates much shading within the first two to three years of growth [37,[40][41][42][43]. In Sweden, which is the northern boundary of oak distribution [44], it has been shown that 10% of full light is necessary for survival and 18% for development [45].…”

Abstract:The study of density and growth of pine, birch and oak seedlings and saplings in canopy gaps in the urban boreal forest in Riga, Latvia, indicates that natural regeneration can increase diversity in small gaps caused by tree mortality, and can ensure conversion from even-aged pine forest. Abundant regeneration in small gaps showed that light (gap area) was only one of the factors affecting tree regeneration in the gaps. The depth of the O layer and pH were suggested to be important factors for the establishment and growth of pine and birch. For oak, the main factors for establishment and growth were favorable moisture, higher pH and N concentration. Knowledge of ecological factors affecting the establishment of seedlings and growth of saplings of the most common trees species in the urban boreal forest is needed to predict successional trajectories and to aid management.

“…The choice of stands was based on existing information on the current distribution of Quercus robur forests in Galicia and their physiographic, climatic and edaphic habitats Díaz-Maroto & Vila-Lameiro 2008b). The oak stands selected must meet the two basic requirements following: 1) At least 80% of stem number were of this species; 2) They must have a minimum area on 0.5 to 1 ha, which allowed appear inventory plots with no apparent problems effect "edge" that distorts the normal growth of some trees.…”

“…Almost all of the Galician oak forests have lack of proper forest management, inherited from centuries ago, because in most cases, lack of economic interest that exists for their use, given the current situation (Ruiz de la Torre 1991; Díaz-Maroto et al 2005;Díaz-Maroto & Vila-Lameiro 2008b). Furthermore, these forests have high environmental concern, being recognized as Habitats of Community Interest as part of the 2000 NATURA Network.…”

Influence of the canopy in the natural regeneration of Quercus robur in NW Spain

et al. 2014

The problem of natural regeneration of forests, in general, is essential especially under the climate change scenario. The canopy influence on the establishment and growth of oak seedlings supposes an approximation to the still lack of knowledge of oak forests heterogeneity. The management directly concerns the radiation that absorbs the canopy and, therefore, to the undergrowth radiation. The aim of the study was to research the existing relationships between the light percentage that crosses the canopy and comes up to the natural regeneration in native stands of Quercus robur L. in Galicia, in NW Spain. After making the stratification of the stands according to their canopy, data collection was based on the percentage of available light in the undergrowth estimated by means of hemispherical photography. The results show that in areas with a better light percentage, there is a greater regeneration density, which is justified by presenting largest development of the vegetation in the partial opening. The most important conclusion is that San Fitoiro forest is the one with better conditions for seedling establishment, because, the percentage of light reaching the understory are the lowest, providing shade conditions turn out to be a clave factor in the germination of acorns and further development of them.
