چکیده
Ailanthus altissima, the invasive forest tree commonly known as tree-of-heaven, has been associated with decreased levels of plant species richness and native diversity. However, this relationship resident plants inconsistently found tree’s influence on seedbank yet to be studied. To further understand long-term impact tree, ten paired invaded-uninvaded sites were identified in Virginia, USA a variety different-aged stands. The herbaceous woody understories for each plot inventoried soil samples collected grown out 34 weeks greenhouse. All most detailed taxonomic level possible. In total, 35 understory species, 62 taxa, 77 taxa identified. between A. altissima presence i) proportion individual that are native, ii) iii) diversity, iv) nonnative diversity analyzed. addition, models including invasion age also considered. We show invasions decrease understory, but not seedbank. Nonnative increased presence. Additionally, nativity became more extreme over time. end by discussing benefits both managing early limit its overall management other restoration plans.
