Seed Bank in Hemlock Removal Experiment at Harvard Forest 2004-2015

The impending loss of hemlock trees due to hemlock woolly adelgid (Adelges tsuga) infestation prompted the need to identify species of plants able to colonize areas where hemlock has been removed. We investigated species present in the seed bank (in 2004 and 2010), the seedling bank (in 2004 and 2010), and seed rain (from 2005-2015) in the Harvard Forest Hemlock Removal Experiment.

受铁杉球蚜（hemlock woolly adelgid, Adelges tsuga）侵染，铁杉林木正濒临消亡，亟需识别可在铁杉被移除的区域定植的植物物种。本研究针对哈佛大学森林铁杉移除实验（Harvard Forest Hemlock Removal Experiment），对种子库（2004年与2010年）、幼苗库（2004年与2010年）以及2005年至2015年的种子雨中的植物物种展开了调查。
