Native trees that have been planted for reforestation are creating enough shade to finally slow the growth of Callery seedlings.

为重新造林而种植的本地树木正在创造足够的树荫，最终减缓豆梨树幼苗的生长。

Callery pear trees are the third most common kind of tree planted along New York City streets, said city parks department spokesman Dan Kastanis.

纽约市公园部门发言人丹·卡斯塔尼斯表示，豆梨树是纽约市街道上第三最常见的树种。

Cities in Virginia, South Carolina, Ohio, and Indiana have also banned or are banning the sale of all kinds of Callery pear trees.

弗吉尼亚州、南卡罗来纳州、俄亥俄州和印第安纳州的城市也已经或正在禁止销售各种豆梨树。

Other states, including North Carolina, are offering free native trees to landowners who show photographic evidence that they have cut down Callery pears on their property.

包括北卡罗来纳州在内的其他州正在向地主免费提供本地树木，只要他们提供照片证明他们已经砍了自家土地里的豆梨树。
