Partiendo de un muestreo llevado a cabo en 100 prados permanentes en la parte alta de la cuenca del río Bernesga, al norte de la provincia de León, se han identificado 34 especies de leguminosas, de las cuales 14 presentan una frecuencia superior al 6% y que son comentadas en este trabajo. Mediante la utilización de perfiles ecológicos, se estudia el comportamiento de dichas especies con respecto a 21 parámetros edáficos obtenidos en cada punto de muestreo.
