High levels of seed dispersal by a declining wintering population of migratory geese

open access: yesFreshwater Biology, Volume 69, Issue 12, Page 1857-1870, December 2024.
Abstract Ducks are known to be important seed dispersers, but the role of geese in plant dispersal is less clear. Wintering populations of migratory geese are undergoing rapid changes in distribution and habitat use in response to climate change and changes in land use, and the implications for seed dispersal have not previously been studied.
