ABSTRACT We assessed the effects of landscape change on the climate regulation ecosystem service in a mountain river basin of Portugal, through the quantification, valuation and mapping of carbon sequestration and storage. The analyses were based on land use and land cover (LULC) changes that took place between 1990 and 2006 and on expected changes defined by three LULC change scenarios for 2020. We used the Integrated Valuation of Ecosystem Services and Tradeoffs model for scenario building and carbon assessment and valuation, and several modelling tools to assess past, current and future carbon in four different pools. Soil organic carbon data was obtained through an extensive sampling scheme across the entire study area. Recent (1990–2006) and expected landscape changes (2006–2020) affected considerably carbon sequestration and storage. Observed landscape changes generally promoted carbon sequestration and storage, and had a positive effect on the climate regulation ecosystem service, both biophysically and economically. Expected LULC changes further extend the capability of the landscape to increase carbon sequestration and storage in the near future. The carbon sequestered and stored in vegetation and soil contributes to avoid socio-economic damages from climate change, while increasing the economic value of particular LULC classes and the whole landscape. These results are essential to inform land planning, especially on how, where and when changes in landscapes may affect the provision of the climate regulation ecosystem service.

Montesinho Natural Park: general description and natural values

J. Castro; Tomás de Figueiredo; Felícia Fonseca; João Paulo Castro; Sílvia Nobre; Luís Carlos Pires

The Montesinho Natural Park (PNM, Parque Natural de Montesinho) is a protected area located in the municipalities of Vinhais and Braganca, in the administrative NUT Alto Tras-os-Montes (PT118), the mountainous region of northeast Portugal. It was created in 1979 and consists of 748 km2 of natural wooded landscape and traditional mountain agricultural landscape, with highly variable gradients.PNM lies in the vast northeast Tras-os-Montes plateau, with average altitude around 750–900 m, which is part of the Iberian Meseta northern block (Medeiros, 1987; Ribeiro et al., 1987). However, in PNM elevation ranges more than 1,000 m, from the lowest point in the River Mente (436 m), its western border, to the top of Montesinho, at 1,487 m. The main altitudinal belts correspond also to the main landforms found in the area.

Carbon and nitrogen in forest floor and mineral soil under four forest species in the Mediterranean region

Felícia Fonseca; Tomás de Figueiredo

The organic and mineral horizons of soils are of great importance in C and N storage in forest areas. However, knowledge of the effects of forest species on the stocks of these elements is still scarce, especially in Portugal. In order to contribute to this knowledge, a study was carried out in forest stands of Pinus pinaster Aiton (PP), Pinus nigra Arnold (PN), Pseudotsuga menziesii (PM) and Castanea sativa Miller (CS), installed in the 1950s in northern Portugal. Sampling areas with similar topography, lithology and climate were selected, in order to better identify hypothesized differences in C and N storage due to forest species effect. In each stand, 15 sites were selected randomly and the forest floor (organic layers) was collected in a 0.49 m2 area. The layers H, L and F of the forest floor were identified and, for L and F, their components were separated in leaves, pine cones/chestnut husks and branches. At the same sites, soil samples were also collected at 0-10 and 10-20 cm depth. At these depths, undisturbed samples were also collected for bulk density determination. The concentrations of C and N were determined in forest floor and mineral components of the soil, and converted in mass per unit area. The quantity of C storage per unit area followed the sequence PN > PM > CS > PP, while for N the sequence was CS > PM > PN > PP, OM and PP keeping the same relative position in the sequence in both C and N concentrations. The PM and CS species store similar amounts of C and N, and about 90% of these elements is found in the upper 20 cm of the mineral soil. In PN and PP species, the contribution of forest floor to the storage of these elements is more expressive than in the other species, but lower than 30% in all cases.

Assessment and suggestions for improvement of soils with different uses in a sector of Montesinho Natural Park, Portugal

Mirian Gutiérrez Montero; Felícia Fonseca; Tomás de Figueiredo; Ángel Sánchez Bellón

The main objective of this study is to evaluate the quality of four soils with distinct uses and managements (pasture, cereal, chestnut and oak) to check whether their use is appropriate and propose improvements. The investigation took place at Vilar de Ossos, a sector of Montesinho Natural Park in northeast Portugal. Results were obtained from field work and laboratory analyses of more than 25 parameters (textural analysis, nitrogen, phosphorous and potassium contents, cation exchange capacity and cation saturation percentage, pH, organic matter, stoniness, useful soil depth, drainage, etc.). An estimation of erosion was also made following the universal soil loss equation. Pasture and oak registered low values on soil erosion while cereal and chestnut had medium values in the same parameter. With the data obtained, we made soil evaluations according to the Agrologic Classes and the Riquier Bramao and Cornet systems. Results indicate that only chestnut soil had low qualities for farming, and that cereal soils needed a change of use. Finally, based on the assessments, recommendations to improve soil quality have been made. For the pasture soil, the proposal is to put the focus on the nutritional values. In the cereal soil, conservation tillage is proposed. In the chestnut soil, stopping the current plowing technique is suggested and, in the oak soil, which is a natural soil, the proposal is to leave it in its current state.
