Also wanted to add - your dd is a little young yet to read the actual book, but if you haven't ever seen it you might think about finding a copy of "A Sense of Wonder" by Rachel Carson. It's a wonderful book that your dd may treasure as she grows older, and right now, even though she's very young, you both might enjoy looking at the pictures together - they are beautiful, and they might help to reinforce for her that even though she's losing one place that she loves, there are still many beautiful places in nature throughout the world, and many people who care very much about preserving them.
Best wishes,
