How about a wildlife tracking kit? You could include items like a guidebook on animal tracks so she can identify what she finds, a waterproof notebook and pen for taking notes, a measuring tape for measuring tracks, and maybe some plaster of paris for making casts of tracks she finds. You could also include a gift card for a local tracking class or nature walk to enhance her skills and knowledge. She would love the opportunity to explore her passion while learning more about animal behavior and ecology.
Or you can get her a star map with the date of your anniversary.
