Nature conservation on the water
Also: environmental protection, breeding season
Packrafts can go almost anywhere. That comes with responsibility: respect protected areas, breeding seasons and water level limits.
Gravel bars are breeding grounds, reed belts are refuges. Where paddling rules apply, there are usually good reasons. Anfibio has published a blog article on nature conservation and packrafts. Take your rubbish with you and only camp where it's allowed.
