Reporter, author, and ecology activist, this feisty 94-year- old has fought for more than 60 years to protect the Everglades, but her spice and strength are barely apparent in this subdued biography in the ``Earth Keeper'' series. Emphasizing personal chronology at the expense of activities and accomplishments, Bryant offers memories of special foods and preschool reading, devotes a page to a reunion with Douglas's father when she was 25, and details the deaths of her aunt and parents. A plus: the swamp is described in quotes from Douglas's own writings. The soft-pencil drawings are charming, but don't capture the Everglades' grandeur. Disappointing. Glossary; index.
