It was commissioned by the Sherford Consortium as a gift to mark the completion of the school building and create a lasting memento.
Its completion coincided with the recent retirement of Sherford Vale head teacher Susie Evans, who had led the school since 2021.
Ms Evans said: "It has been a joy to see the children's original artwork transformed into this permanent mural in the heart of our school.
"It's about developing those individuals to become who they want to be and if they can make a change to this world, then that'd be brilliant.
"What's quite sad is that, potentially, some of those animals in their design may well be extinct in future years."
Ms Johnson said of the piece: "It's been a privilege to bring the children's vision to life in such a beautiful space.
"Hopefully it will inspire them to love and learn to protect nature and understand that we are a part of nature."
