野生海狸在英格兰诺福克郡成功繁殖，这标志着该物种在当地的重要回归1。两只幼崽是去年12月神秘抵达彭斯索普自然保护区的一对野生海狸的后代1。英格兰本土海狸物种曾在16世纪初被猎杀至灭绝，此次新生幼崽的诞生打破了超过500年的断层1。
彭斯索普自然保护区正计划扩大海狸种群规模1。保护区经理理查德·斯波韦奇表示，需要建立更广泛的遗传库来维持健康的种群1。距离该地点最近的野生海狸种群位于肯特郡斯托尔河，相距超过130英里1。保护区正在众筹资金，以申请政府许可引入更多海狸1。海狸对当地生态的积极影响已初显端倪，其修建的水库在热浪期间为相邻农田蓄水达300万升，并为蓝山雀、水鸟、狐狸、獭等多种野生动物提供了栖息环境1。
Two beaver kits have been born in Norfolk, marking the first wild beaver offspring to arrive in England in more than five centuries 1. The young beavers are the offspring of a pair of wild beavers that mysteriously appeared on a river at Pensthorpe Nature Reserve in December 2024 1. This birth represents a significant milestone in the restoration of England's native beaver population, which was hunted to extinction in the early 16th century 1.
The reserve is now seeking to expand the beaver population through crowdfunding efforts aimed at securing government permission to introduce additional beavers to the area 1. According to Richard Spowage, the reserve's manager, establishing a sustainable population requires more than a single family: "You can't have just one family in the river system. You need a wider genetic pool" 1. The nearest existing wild beaver population is located over 130 miles away on the River Stour in Kent 1.
Beyond reproduction, the beavers have already begun reshaping their habitat. During a heat wave, a local farmer reported that a beaver-constructed reservoir on his land held approximately three million liters of water 1. The river channel now serves as a focal point for local wildlife, including blue tits, waterfowl, foxes, and otters 1.
