Estas especies tampoco utilizaron los pasos inferiores y superiores suficientemente grandes como para permitir su paso. La v\u00eda de tren probablemente ha conttibuido a reducir los movimientos de los ungulados y por ello son necesarios pasos dise\u00f1ados espec\u00edficamente para este grupo con la finalidad de evitar el efecto barrera.\nLa respuesta de otros grupos de vertebrados terrestres (carn\u00edvoros, lagomorfos, peque\u00f1os mam\u00edferos y reptiles) a la l\u00ednea ferroviaria no se conoce con detalle, pero todos ellos utilizaron de manera regular los drenajes y otras estructuras transversales, lo que sugiere que el posible efecto barrera ejercido por la infraestructura puede verse reducido por el uso de estas estructuras como pasos. Las frecuencias de cruce de estos grupos de vertebrados a trav\u00e9s de pasos no espec\u00edficos para la fauna no resultaron afectadas por la presencia del vallado en los m\u00e1rgenes de la v\u00eda, lo que refuerza la afirmaci\u00f3n que no significaba un importante efecto barrera. El \u00e9xito de las estructuras como pasos para la fauna depende principalmente de su ubicaci\u00f3n en el h\u00e1bitat id\u00f3neo de la especie de inter\u00e9s y en segundo lugar, de un dise\u00f1o apropiado de los pasos y las \u00e1reas alrededor.\nLa frecuencia de uso de diferentes pasos tambi\u00e9n reflejaba la preferencias en relaci\u00f3n con el microh\u00e1bitat. El uso de drenajes, pasos inferiores y superiores por parte de los carn\u00edvoros fue favorecido por la presencia de vegetaci\u00f3n en las entradas. Los peque\u00f1os mam\u00edferos mostraron preferencia por drenajes de di\u00e1metro peque\u00f1o, probablemente porque pueden desplazarse a trav\u00e9s de ellos protegidos contra los predadores a\u00e9reos.
