These new works are a celebration of just a few of the keystone species which are essential to a balanced and healthy ecosystem. As with the keystone in a masonry arch, a keystone species, which can be any organism from large mammals to bacteria & fungi, is a pivotal component in maintaining the delicate balance of an ecological structure. If that species is removed, it sets off a chain reaction which can cause the whole system to collapse.
Indigenous people, living intimately with the natural world, have always understood this balance. As our societies have become urbanised and more detached, so that understanding has become lost in our enthusiastic exploitation of the planet.
