五百多只山羊进驻公园「啃」出防火带：消防部门首个定向放牧试点展开
加利福尼亚州圣迭戈县10月30日通报：约525只山羊已经进驻圣迭戈县谷地中心（Valley Center）的星谷公园（Star Valley Park），开始啃食园内灌木杂草。这是圣迭戈县消防局首个「定向放牧」试点项目，用羊群代替机械与人工，为公园清出防火植被带。
县府表示，这群山羊将在约两周内啃食约38英亩的灌木地。定向放牧近年在加州多地被用于野火预防：羊群能进入机械难以作业的坡地，啃食高度与密度可控，且不产生火花与噪音。
县消防局正争取加州消防局（Cal Fire）野火预防计划的一笔三十万美元拨款，以支持把这一做法推广到更多县立公园与开放空间；拨款目前尚在申请阶段。县府提醒，放牧期间到访星谷公园的居民应与羊群及牧犬保持距离，不要投喂。
More Than 500 Goats Graze a County Park in County Fire's First Targeted Grazing Pilot
San Diego County, California, reported on October 30 that about 525 goats have moved into Star Valley Park in Valley Center to graze down brush and weeds, in San Diego County Fire's first targeted grazing pilot, using a herd in place of machinery and hand crews to clear fire-prone vegetation.
The county said the goats will work through about 38 acres of brush over roughly two weeks. Targeted grazing has spread across California as a wildfire prevention tool: goats can reach slopes that machines cannot, graze to a controlled height and density, and do the work without sparks or noise.
County Fire is seeking a $300,000 grant from the Cal Fire Wildfire Prevention Program to extend the approach to more county parks and open spaces; the grant is still pending. The county asked Star Valley Park visitors to keep their distance from the herd and its guard dogs during the grazing period and not to feed the animals.
