The Water Guardians / Aqua Squad
‘The availability of [potable] water, more than any other environmental factor, wll determine where we live and what we do.”[i]
Water is essential for all life; be it human, animal, plant or insect. Yet less than one percent of all water on earth is fresh and available for use. Given its critical importance, any animal that saves and improves that water has to be of similar value. We are just beginning now to understand how lucky we are to share our waterways with beavers who instinctively tend this resource in such a way that it benefits their own lives and others. Beaver dams improve water quality by reducing toxins and nitrogen, as well as assisting with sediment removal, nutrient cycling, erosion control and water clarity. The deeper water of beaver ponds recharges groundwater and these benefits increase as temperatures warm from climate change.[ii]
Learning about the finite nature and critical importance of water is part of how children come to understand resource scarcity and the impacts of their actions and choices on others. It prepares them for stewardship and introduces them to environmental science. Understanding the water cycle and its effect on survival is a key lesson in how the world works, and it is a mistake to tell this story without including the role of the beaver.
The Water Guardians is an activity designed to highlight the beaver’s key role in that critical cycle. It shows their stewardship of water and how their work preserves and filters it, reducing sediment and removing toxins, slowing it down in its course and pushing it underground where it becomes cooler. Compared to a stream without beavers a waterway with beavers is deeper, cooler, cleaner and slower, Children will learn this as they collect the four stickers that describe these qualities then place them on a water attributes card that features them all. Complete cards can be presented to earn a tiny symbolic vial of water with a beaver on a cord that they can wear, so that children can more easily remember the important connection between the two.
