Vallas virtuales: ¿buenas para las granjas y la naturaleza?

Virtual fences: good for farms and nature?

Lee un fragmento de un reportaje de VOA Learning English que compara las vallas tradicionales con las vallas virtuales con GPS para el ganado.

Antes de leer

En algunas granjas, el ganado lleva ahora collares con receptores GPS. Cuando un animal se acerca a una línea invisible que el ganadero ha trazado en un teléfono o una computadora, el collar emite un sonido de advertencia y luego da una pequeña descarga eléctrica. Esto se llama cercado virtual. Jim Strickland, ganadero de Florida, lo usa en las tierras donde trabaja. Lee esta parte de un reportaje de VOA Learning English sobre las vallas tradicionales y los posibles beneficios de las virtuales.

Virtual Fences for Cows Show Benefits

Physical fences take time, labor and money to build. It can be difficult to put them in areas such as rocky and hilly land, wet areas, or places with thick vegetation. Over time, fences need to be fixed or new ones need to be built.

When hurricane Ian hit Florida last year, it destroyed four houses and 45 kilometers of physical fence on the land where Strickland works. But the cell towers for the virtual fence system kept working.

Physical fences can also harm wild animals by making it difficult for them to move within and to areas they need for survival.

The Nature Conservancy (TNC) is a U.S-based environmental non-profit organization. It has partnered with cattle ranches in the states of Kansas, New Mexico and Colorado to research the effects of virtual fencing.

William Burnidge is Deputy Director of TNC’s North America Regenerative Grazing Lands Strategy. He said that by changing fence boundaries, the systems prevent animals from eating too much vegetation within one area. This helps plants regenerate, or grow again.

He added that virtual fences could help protect rare plants and areas near rivers and streams. They could also support conservation of wild animals, improve the health of animals and help ranch workers have a better quality of life.

Strickland works with partners at Florida Conservation Group and the University of Florida. With virtual fences, they can carefully control grazing. This helps them research the effects of grazing patterns on the growth of young cows, birth rates, and even the effects on nesting birds.
