A close-up look at wetlands ecology.

A printer-friendly version of this page 12 minutes
Directed by Don White
Produced by The National Film Board of Canada

Using exquisite underwater micro-photography, this National Film Board of Canada production provides a close-up look at an estuary-- the biologically important wetlands where the fresh water of a river meets the salt water of the ocean. As we watch barnacles feeding themselves and the comic acrobatics of diving ducks, the film details the complex ecology of estuarine life; and, in an understated manner, makes a powerful case for protecting wetlands.

"The concept of the food chain is soundly illustrated in this film...Provides a concise, enjoyable, and informative look at life in an estuary. Recommended for instructional use in general biology and ecology courses."

"Within its small, beautifully circumscribed compass, this is a perfect example of a fully achieved work which ultimately links the complexity of one particular ecostructure (and fills us with respect for its perfection) to our present-day social webs."
Amos Vogel, Film Comment

"The ecological principles are the same worldwide and their treatment in this film is valuable for upper elementary through adult education on estuarine ecology."
