Rosa rugosa as an Invader of Coastal Sand Dunes of Cape Breton Island and Mainland of Nova Scotia
Rosa rugosa is described for the first time as an invasive species associated with coastal sand dunes in Atlantic Canada. Our surveys of 24 beaches on western Cape Breton Island and the mainland of northern Nova Scotia from Cheticamp to Fox Harbour showed that 11 of the dune systems (ca. 45%) were c...

Rosa rugosa is described for the first time as an invasive species associated with coastal sand dunes in Atlantic Canada.
