“…Litter production seems to decrease proportionally with the stand basal area (Hennessey et al 1992;Kunhamu et al 2009;Navarro et al 2013;Trofymow et al 1991). Nonetheless, the mechanisms behind reduced litter production are not straightforward.…”

“…Soil temperature was measured in all the plots, except the T75 plots of blocks II and III. Understory air temperature (1.5 m high) was measured in the T0, T60 and T100 plots of block I Eur J Forest Res (2016) 135:203-214 207 which is the typical pattern of this species (García-Plé et al 1995;Navarro et al 2013). In the clearfelling plots, however, a dramatic change in the distribution of fractions occurred, which smoothed the monthly dynamic pattern (Fig.…”

Our knowledge about the influence of silvicultural treatments on nutrient cycling processes in Mediterranean forests is still limited. Four levels of tree removal were compared in an Aleppo pine forest in eastern Spain to determine the effects on litterfall, litter decomposition and the associated nutrient fluxes after 12 years. Removal treatments included clearfelling, two shelterwood intensities (60 and 75 % of basal area removed) and untreated controls. Twelve years later, the basal area removed still explained 60 % of litterfall mass variance and 60 % of C, 52 % of N, 45 % of P, 17 % of K, 47 % of Ca and 60 % of Mg return variances. Litter decomposed somewhat more slowly in clearfellings compared to controls (p = 0.049), accumulated more Ca and released less K compared to the other three treatments. This was explained by contamination with mineral particles due to the poorly developed O horizon in clearfellings. We conclude that the management practices reduced the nutrient return via litterfall, but the nutrient release through decomposition seems poorly sensitive to canopy disturbance. In order to accurately quantify the harvesting impacts on nutrient cycling in this Mediterranean forest system, it is necessary to measure the litterfall of the understory layer.

“…El efecto del AB local sobre la producción de desfronde observado en las masas de ambas especies ha sido significativo y positivo y coincide con lo descrito previamente por diversos autores para distintas especies (Kunhamu et al 2009, Navarro et al 2013, Lado-Monserrat et al 2015, lo cual indica que una mayor espesura (medida en térmi-nos de AB local ) conlleva una mayor biomasa de acículas por unidad de superficie en la masa forestal y, por tanto, una mayor cantidad de desfronde.…”

“…Es fundamental conocer las tasas de desfronde y descomposición de las masas, así como la relación existente entre el desfronde y su descomposición y la densidad de las masas para asegurar el mantenimiento de la sostenibilidad a través de la gestión forestal. La producción de desfronde disminuye a medida que se reduce el área basimétrica de las masas (Roig et al 2005, Kunhamu et al 2009, Navarro et al 2013, igualmente la descomposición de dicho material se ve influida por el distinto microclima ocasionado bajo masas de distintas densidades, aunque el signo de esta relación no siempre es el mismo (Aceñolaza y GallardoLancho 1995, Roig et al 2005, Kunhamu et al 2009). …”

Influencia de la densidad del arbolado sobre el desfronde y su reciclado en pinares de repoblación del norte de EspañaEffects of stand density on litterfall and its turnover in pine plantations in northern Spain SUMMARYThe main objective of this work was to study the dynamics of litterfall and litter decomposition in Pinus sylvestris and Pinus halepensis plantations in Castilla y León Region (Spain) as well as the effect of local density on these parameters. Four stands of each species were selected and eight plots were established on each stand. A littertrap and 15 litterbags were set on each plot. Litterfall was collected monthly and a litterbag was removed every three months. The dry weight of litterfall was determined separately for each fraction. The loss of weight over time of needles in the litterbags was also determined. Finally, the relationship between local basal area in the plots and the studied parameters was assessed. The obtained results show significant and positive effects of basal area on litterfall and significant and negative effects on decay rate of needles in the litterbags.Key words: basal area, litterbag, Pinus halepensis, Pinus sylvestris, littertrap. RESUMENEl objetivo del presente trabajo fue estudiar las dinámicas de desfronde y descomposición de acículas en plantaciones de Pinus halepensis y Pinus sylvestris de Castilla y León (España) así como el efecto de la densidad de las masas sobre dichos parámetros. Para ello se seleccionaron cuatro rodales de cada una de las especies estudiadas y en cada uno de ellos se establecieron ocho parcelas considerando un gradiente de áreas basimétricas, estudiándose un total de 32 parcelas. En el centro de cada parcela se situó una trampa de desfronde y 15 bolsas de descomposición. El desfronde contenido en las trampas se recogió mensualmente. Trimestralmente se retiró una bolsa de descomposición de cada parcela. Se determinó el peso seco de desfronde separado en las distintas fracciones así como la pérdida de peso de las bolsas de descomposición a lo largo del tiempo. Finalmente se estudió la relación existente entre el área basimétrica local de las parcelas y los parámetros antes descritos. Se constató la existencia de diferencias significativas en las cantidades de desfronde y en la tasa de descomposición de las acículas contenidas en las bolsas en función del área basimétrica de la parcela.Palabras clave: área basimétrica, litterbag, Pinus halepensis, Pinus sylvestris, trampa de desfronde.
