Evaluation of the interest of southern Patagonian ranchers toward selective and efficient predator control methods.
Sheep ranchers (n = 90) were surveyed to evaluate their interest in the incorporation of predator selective control methods. We based our survey on the characterization of the sheep ranching system of Santa Cruz province and its relationship with culpeo fox (Lycalopex culpaeus) predation. For a larg...

| description | Sheep ranchers (n = 90) were surveyed to evaluate their interest in the incorporation of predator selective control methods. We based our survey on the characterization of the sheep ranching system of Santa Cruz province and its relationship with culpeo fox (Lycalopex culpaeus) predation. For a large percentage of producers (73%), the carrying capacity at present is under the optimal, which is consistent with the fact that sheep ranching represents only a part of their income. Lamb losses due to culpeo foxes predation vary between 5% and 50% of the annual lamb production, and these percentages did not vary during the last years in spite of the perceiving, by 53% of ranchers, of an increment in foxes abundance. Ranchers tend to exaggerate real losses of their lambs due to predation, although they recognize that there are other causes that could facilitate it. Nevertheless, fox control, including poisoning as a method, is still a current practice even in those ranches without sheep. The 90% of the sheep ranchers showed a good willingness to replace their current practices by selective and efficient control methods. This is an important point to encourage the use of selective control methods, like toxic baits delivered in a selective way, which would allow the abandonment of the traditional practices so dangerous to biodiversity conservation |

Sheep ranchers (n = 90) were surveyed to evaluate their interest in the incorporation of predator selective control methods. We based our survey on the characterization of the sheep ranching system of Santa Cruz province and its relationship with culpeo fox (Lycalopex culpaeus) predation.

Para los encuestados (n = 90) la carga ovina actual está por debajo de la óptima, lo que es consistente con el hecho de que para la mayoría (73%) la ganadería solo representa una parte de sus ingresos. El nivel de pérdida de corderos por predación de zorros colorados varía entre el 5% y el 50% de la producción anual y esta tasa se ha mantenido en los últimos años, a pesar de que el 56% de los encuestados percibe un aumento en la abundancia de zorros en sus campos en los últimos 10 años. Las actitudes negativas de los productores hacia el zorro colorado se reflejaron en el hecho de que su control continúa siendo una práctica habitual para el 73% de los encuestados incluso en establecimientos sin producción. El uso de veneno es o ha sido utilizado por la mayoría de los productores (74%) a pesar de su prohibición. Sin embargo, el 91% de los encuestados estaría dispuesto a reemplazar sus prácticas por métodos de control selectivos y eficientes. Este es un punto importante para incentivar el uso de métodos alternativos de control, como cebos tóxicos administrados selectivamente, lo que permitiría el abandono de las prácticas tradicionales tan nocivas para la conservación de la biodiversidad.
