Abstract:
Chinese yew (Taxus wallichiana var. mairei) is ranked as a rare and endangered plant of first-grade protection of China. It has been widely cultivated in 17 provinces of China over the past few decades. However, little is known about the dispersion, rewilding, and ecological influence of Chinese yew\'s offspring during cultivation. Here, we report a noteworthy case of this species, via ex situ conservation, which has successfully spread into different secondary forests, thus forming a stable regenerating population in eastern China. The establishment of this yew population, which has > 900 individuals and 7 ha area, can be ascribed to two key ecological factors: (1) secondary forest near the parent yews that provided suitable microhabitats in which progeny yews could germinate and grow, and (2) seed-foraging and transportation by native birds. Thus, this case may offer a pathway for conserving endangered Chinese Taxus species, which can attract frugivorous birds to disperse their seeds. In addition, it is necessary to monitor the growth performance of progeny population in the field.
摘要:
中国红豆杉(Taxuswallichianavar。mairei)被列为中国一级保护的珍稀濒危植物。在过去的几十年中,它已在中国17个省广泛种植。然而,对这种分散知之甚少,rewilding,栽培过程中对中国红豆杉后代的生态影响。这里,我们报告了这个物种的一个值得注意的案例,通过异地保护,它已经成功地传播到不同的次生林,从而在中国东部形成稳定的再生人口。这个紫杉种群的建立,拥有>900个人和7公顷的面积,可以归因于两个关键的生态因素:(1)在亲本酵母附近的次生林提供了合适的微生境,后代酵母可以在其中发芽和生长,和(2)本地鸟类的种子觅食和运输。因此,此案可能为保护濒危的中国红豆杉提供了一条途径,这可以吸引节食的鸟类散布种子。此外,有必要在田间监测后代种群的生长性能。
