Carbon and nutrient contents in the miscellaneous fraction of litterfall under different thinning intensities in a semiarid Pinus halepensis afforestation

Abstract

Biogeosciences and Forestry Biogeosciences and Forestry Carbon and nutrient contents in the miscellaneous fraction of litterfall under different thinning intensities in a semiarid Pinus halepensis afforestation Carmen Segura (1) , Emilia Fernández-Ondoño (1) , M Noelia Jiménez (2) , Francisco B Navarro (3) Litterfall evaluation and the effects caused by forestry practices provide valuable information on nutrient-cycle dynamics in managed forests. So far, most of the studies have focused on leaf-fall, omitting other litterfall fractions that can be also relevant for forest and soil modelling in a global change context. With this aim the miscellaneous fraction was quantified in a Pinus halepensis afforestation in the semiarid SE of Spain five years after four different thinning regimes were applied (T75: 75% of mean basal area removed; T60: 60%; T48: 48%; and T0: no thinning). Concentrations and pools (kg ha-1) of carbon and nutrients in the miscellanea fraction were monthly analysed for C and N

Biomass, radial growth and regeneration capacity of Aleppo pine, and its possible use as rootstock in arid and degraded areas

“…and along the coasts (Elaieb et al 2017) in dry and warm environments (Neeman & Trabaud 2000). In Aleppo pine forests, nutrient cycling is influenced by litterfall and silvicultural practices (Segura et al 2019). The species is characterized by a high production of seeds with a great capacity of natural dispersion, thus favoring the regeneration and expansion in suitable habitats.…”
