    Effects of different clipping intensities on above- and below-ground production in simulated herbaceous plant communities
    (Plant Biosystems, 2016) Herrero Jaúregui, Cristina; Schmitz García, María Fe; Díaz Pineda, Francisco
    We studied the effect of clipping on above- and below-ground production in different plant communities through a factorial experiment. We designed five pasture systems with different species composition, perennials/annuals ratio and soil water availability, recreating different altitudinal locations, and simulated a gradient of grazing intensity by clipping with different heights and frequencies. Response patterns of above- and below-ground production were similar, increasing with the higher clipping frequency and decreasing with altitude. These results suggest that high grazing intensity stimulate above-ground production, but only in certain situations of species composition, density, diversity,perennials/annuals ratio and water availability. This stimulus, however, is unsustainable over time, and the lower clipping frequencies are those that favour the maintenance of production.

    Evaluating the role of a protected area on hedgerow conservation: the case of a spanish cultural landscape
    (Land Degradation & Development, 2016) Schmitz García, María Fe; Herrero Jaúregui, Cristina; Arnaiz Schmitz, Cecilia; Sánchez, Iván A.; Rescia Perazzo, Alejandro Javier; Díaz Pineda, Francisco
    Hedgerows are key features in agricultural landscapes performing diverse functions that are both economically and ecologically significant. Here, we quantify how the characteristics of a relict hedgerow network of a Spanish cultural landscape (Guadarrama mountains in the north of Madrid region) have changed over a single decade both inside and outside the boundaries of a Protected Area, the aim of which is to conserve cultural uses and biodiversity. A gradient of abandonment of pasture systems was detected, including a decline and loss of woody species from hedgerows associated with grazed areas towards shrub encroachment zones. These tendencies were similar inside and outside the boundaries of the Protected Area. The results highlight the management weaknesses of the Protected Area in order to achieve its objectives.Based on the results, we propose to include a specific conservation status for hedgerow landscapes in the regulatory framework of Spanish protected areas.
