[ES]Se realizan controles anuales, durante siete años (1986/93), de la producción de biomasa aérea neta en comunidades de pastizales seminaturales. Así mismo se consideran las proporciones de materia seca de cada componente botánico (gramíneas, leguminosas y otras familias) sobre el conjunto del pasto. El estudio comprende también el efecto de la posición topográfica sobre los parámetros citados, realizándose medidas anuales en las dos zonas extremas (baja y alta) de 40 laderas, representativas de pastizales adehesados en la provincia de Salamanca. La producción media global (considerando años y zonas) fue de 133 g/m2 de materia seca en las zonas altas. Para las bajas asciende a más del doble (293 g/m2). En este extremo de la ladera las gramíneas tienen un dominio muy marcado, sin embargo el grupo de otras predomina en la zona de erosión (alta).
[EN]Annual controls were made over a period of seven years (1986/93) on the net aerial biomass yield in communities of seminatural grasslands. The dry matter in each botanic component (grasses, legumes and other families) in the pasture land as a whole was also taken into account. The study also comprises the effect of topographical position on the aforementioned parameters, annual measurements having been taken in the extreme areas of the slopes (highest and lowest) in representative grasslands in the “dehesas” of the province of Salamanca. The average total yield (taking into account years and areas) was 133 g/m2 dry matter in the upper zones. On the lower sites it was more than double (293 g/m2). On the low slopes there is a great predominance of grasses, whereas the other families predominate in the eroded areas (high zones).
