I take a similar approach in this children's book: https://github.com/ralienpp/book-two. In the end there is a section about the trees* that grow in the area, their leaves and fruits - so kids can learn to identify them. I'll incorporate some of these materials in the next iterations of the book.

The first link in the repo readme is for the on-screen PDF, you can look at the pictures.

* One of the characters in the story uses trees to figure out where they are and find their way back home.

It would be cool if there was like an interactive and facillitated way to filter all the stuff for that which is local and that they can seek out, like Pokemon Go or whatever

Maybe not. Would be confusing for the children.

After taking a quick look, many of this fruit varieties don't exist anymore. Other were renamed and other paintings reflect fruit diseases, not the fruit itself. Botanical art is valuable art, but this work does not reflect the present.

Maybe it could focus on what's still around but there's a section later on where they deal with older or non-existent stuff.

Why is ur sense of childlike wonder so ant-sized?
