Cover for Management and ecological implications of silvopastoral systems in the Alps.

In the Alps, 15% of the mountain forests are grazed, mainly by cattle browsing young trees, thus reducing the protection function of the forests against natural hazards. In this study, the condition of young trees on subalpine wood-pastures was assessed, the selection of herbaceous species was...

Cover for Light availability for understorey pasture in holm-oak dehesas.

The percentage of radiation transmitted through the tree layer to the understorey pasture in dehesas of west-central Spain has been modelled. To achieve that, different allometric relationships between tree ages and stem diameter (DBH), and between stem diameter and canopy size (tree height, canopy ...

Cover for Structure characterization of <i xmlns="http://www.w3.org/1999/xhtml">Quercus pyrenaica</i> Willd. open woodlands in the Spanish Central Mountain: implications for silvopastoral management.

This chapter presents a preliminary characterization of Quercus pyrenaica Willd. open woodlands in Madrid province. From data from the second and third National Forest Inventory we compare main stand variables (N, Dg, Hm, Ho, G, V and Hart-Becking index) at the two inventories for open woodlands...

Cover for Effects of grazing on <i xmlns="http://www.w3.org/1999/xhtml">Quercus faginea</i> Lam. forests in Navarra (Spain).

We report the effect of grazing in four dense forests of Quercus faginea Lam. in central Navarra. Tree density was 2550 trees/ha and canopy cover was 93%. Grazing significantly increased soil denudation. The cover of Helictrotrichon cantabricum decreased significantly although other grasses such as ...

Cover for Effect of fertilization, tree species, plantation density and sowing mixture on pasture production and soil characteristics in silvopastoral systems.

The aim of the experiment was to test the effect of three fertilizer treatments (no fertilizer, organic fertilizer and inorganic fertilizer) on cocksfoot pasture established under two tree species (Betula alba and Pinus radiata) at two densities (2500 and 833 trees/ha). After 7 years the effects of ...

Cover for Tree growth and pasture production under sewage sludge fertilization.

The objective of these experiments was to compare the effect on pasture production and tree growth in a silvopastoral system of no fertilization, three doses of sewage sludge, with or without liming, and the fertilization usually used in the region. The experiment was conducted over 3 years in the...
