The researchers say if you joined up all the hedgerows in England, they would stretch almost ten times around the Earth. Their map, which is based on laser scanning hedges from the air rather than scaling up information from field surveys, gives a more complete picture of the quality and quantity of hedgerows across the country.

研究人员们说，如果你把英格兰所有的树篱连起来，得到的长度可以绕地球近十圈。研究人员使用的地图是基于从空中对树篱进行激光扫描绘制而成的，不是靠扩大实地调查得到的信息制成的，因此更全面地反映了英格兰各地树篱的质量及数量。

The South West boasts the most hedges, led by Cornwall. Excluding big urban areas such as London and Merseyside, Surrey, Hampshire and Berkshire are the counties with the least.

英格兰西南部拥有的树篱数量最多，其中康沃尔郡排在首位。除去伦敦、默西塞德等大城市地区，萨里郡、汉普郡和伯克郡拥有的树篱数量最少。

The scientists hope their new data will help restore a vital habitat for wildlife that also stores large amounts of carbon. Thousands of miles of hedgerows have been lost since the 1950s to intensive farming and development. And the government has set ambitious new targets to reverse this decline.

科学家们希望新数据将有助于使树篱恢复生机，它不仅是野生动物的重要栖息地，还能吸收并储存大量的碳。自20世纪50年代以来，由于集约型农业和土地开发，数千英里的树篱已经消失不见。为了扭转树篱数量减少的趋势，英国政府已定下一系列重大的生态保护新目标。
