A land bridge, in
biogeography, is an
isthmus or other land connection between what at other times are separate areas which allows animals and plants to cross and colonise new lands. Land bridges are commonly created by
regression, in which
sea levels fall exposing previously submerged sections of
continental shelf. Land bridges are also formed by: (a) upthrust at the edge of continental plates; and (b) glacial retreat alleviating pressure on shallow marine formations (e.g. the emergence of
Oland,
Sweden)
