Recinzioni virtuali: un bene per gli allevamenti e per la natura?

Virtual fences: good for farms and nature?

Leggi un estratto di un articolo di VOA Learning English che confronta le recinzioni tradizionali con quelle virtuali basate sul GPS per i bovini.

Prima di leggere

In alcune aziende agricole i bovini ora portano collari con ricevitori GPS. Quando un animale si avvicina a una linea invisibile tracciata dall'allevatore su un telefono o un computer, il collare emette un suono di avvertimento e poi dà una piccola scossa elettrica. Questo si chiama recinzione virtuale. Jim Strickland, un allevatore di bovini della Florida, la usa nel terreno in cui lavora. Leggi questa parte di un articolo di VOA Learning English sulle recinzioni tradizionali e sui possibili vantaggi di quelle virtuali.

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.
