Manage water level in wetlands Bird Conservation

A study in 1958-1967 on Squaw Creek National Wildlife Refuge, Missouri, USA (Burgess 1969), found that, in general, ducks increased when the largest expanses of marshes were flooded, and geese were most abundant when the largest areas of marshes and forage plants were available in response to lowered water levels. The use of the wetlands is discussed in ‘Habitat restoration and creation’.

 

Restore or create inland wetlands Bird Conservation

A study in 1958-1967 on Squaw Creek National Wildlife Refuge, Missouri, USA (Burgess 1969), found that annual use of the 2,772 ha wetlands (created in 1935)  varied from 6-27 million duck-days and from 7-19 million goose-days each year. Management included winter water removal to aerate the soil and eradicate carp, and spring flooding.
