Key ID Features:
- deciduous tree, open crown
- hairy and white below
- small, light brown, tomentose buds appressed
- white showy bark, ridged
- stems gray with dark splotches
- Bigtooth aspen (Populus grandidentata), Quaking aspen (P. tremuloides), and Populus hybrids
- Can form large clonal communities that can crowd out native species in edge habitats
- Removal attempts show vigorous resprouting and spread
- Within disturbed sites it can be very competitive and disrupt natural succession
- Populus alba is easily broken and can damage surrounding trees or structures.
- This is one of the most invasive plants on Nantucket. The Polpis area is very heavily invaded, even far back into the moors. Since a lot of the places it has invaded there get mowed, plants may be hard to see. It is also found at Polpis Harbor, where the forest is dominated by this species. A forest near the Loran by the Sconset Dump is infested.
