“…The results of this preliminary study indicate the model can be used to evaluate the impact of adaptive silviculture to mitigate decline processes at rear edge forests. Some future works might look at climatic and edaphic gradients within this area using a GIS approach such as Almeida et al (2010). Because water limitation is possibly behind forest decline in these forests, some focus could be put into the measurement and mapping of Available Soil Water along topographic gradients in the area.…”

Aim of the study : We assessed the ability of the 3-PG process-based model to accurately predict growth of Pinus sylvestris and P. nigra plantations across a range of sites, showing declining growth trends, in southern Spain.Area of study: The study area is located in "Sierra de Los Filabres" (Almería). Material and methods:The model was modified in fifteen parameters to predict diameter (DBH, cm), basal area increment (BAI, cm 2 yr -1 ) and leaf area index (LAI, m 2 m -2 ) in healthy trees and trees showing declining growth. We assumed that a set of specific physiological parameters (stem partitioning ratio-pFS 20 , maximum litterfall rate-γ Fx , maximum canopy conductance-g Cx , specific leaf area for mature aged stands-σ 1 , age at which specific leaf area = ½ (σ 0 + σ 1 ), age at full canopy cover-t c , and canopy boundary layer conductance-g B ) included in 3-PG would be suitable for predicting growth decline related to climate conditions. The calibrated model was evaluated using dendrochronological and LAI data obtained from plots.Main results: Observed and simulated DBH showed a high correlation (R 2 > 0.99) between modelled and measured values for both species. In contrast, modelled and observed BAI showed lower correlation (R 2 < 0.68). Sensitivity analysis on 3-PG outputs showed that the foliage parameters -maximum litterfall rate, maximum canopy conductance, specific leaf area for mature aged stands, age at which specific leaf area, and age at full canopy cover -were important for DBH and BAI predictions under drought stress.Research highlights: Our overall results indicated that the 3-PG model could predict growth response of pine plantations to climatic stress with desirable accuracy in southern Spain by using readily available soil and climatic data with physiological parameters derived from experiments.

“…This kind of maps provides an overview of the area and confirms the existence of distinct management zones, which deserve special attention. Moreover, the maps obtained will adjust ecophysiological spatial models of wood productivity (Landsberg and Gower, 1997;Almeida et al, 2010), for classifying the quality of forest sites (Fisher and Binkley, 2000), for the estimation and mapping of erosion (Brady and Weil, 2008) and for management of nutrients budgets in areas of forest plantations.…”

Capão Bonito forest soils, São Paulo state, Brazil, have been used for forestry purposes for almost one century. Detailed knowledge about the distribution of soil attributes over the landscape is of fundamental importance for proper management of natural resources. The purpose of this study was to identify the variability and spatial dependence of chemical and physical attributes of Capão Bonito forest soils. A large soil database of regional land was raised and organized. Most of the selected variables were close to the lognormal frequency range. Soil texture presented a higher range in the A horizon, and the nugget effect and sill were greater in the B horizon. These differences are attributed to the parent material of the region (Itararé Geologic Formation), which presents uneven distribution of sediments. Chemical attributes related to soil fertility presented a higher spatial dependence range in the B horizon, probably as a result of more intensive management and erosion history of the superficial soil layer. Maps for some attributes were interpolated. These had specific areas of occurrence and a wide distribution along the perimeter of the Capão Bonito District Forest, allowing a future site-specific soil management.

“…Sin embargo, con el objetivo de obtener los rendimientos que el modelo predice debería de realizarse un mantenimiento a estas plantaciones que controle las malezas de una mejor manera. Se ha reportado que una variación de los recursos podría afectar la modelación en el corto plazo (Almeida et al, 2010), claramente las malezas no solo compiten por los recursos por lo que el modelo permitió conocer el rendimiento de plantaciones dendroenergéticas manejadas intensivamente.…”
