Eh? What? Trophic cascades? What’s that then?
Forest school has helped me to understand, and even to notice, the natural world around us. It is great to see children with their enthusiasm start to take an interest in the wildlife all around us. Hopefully we can influence a generation which cares enough to change the world for the better.
This is a great video about what happened when wolves were reintroduced to Yellowstone National Park in the United States. It describes how the wolves changed the whole ecosystem for the better, bringing balance to the area.
A trophic cascade is what can happen when changes are made at the top of a food web which brings changes throughout the whole ecosystem. The best way to understand it is to watch the video, it is amazing.
If you are a teacher teaching about ecosystem and food webs this may be a good one to use.
Now I’m hoping we could reintroduce wolves here in the UK.
