Nature Exchange Rules Nature Exchange Rules Please leave bird’s nests, wasp’s nests, eggs, dead or alive animals, and living plants in the wild. Nature needs these things more than us! Snap a photo or draw us a picture instead. Collect only one of each of the different things you find. 100 pinecones are not very exciting for you or us! No more than 3 items at a time for exchange. Leave protected and rare things right where they are, this is a law; so it’s best not to break this rule! We DO encourage you to take field notes using your nature journal when you do find or observe something wonderful in those protected areas.
