A clone forest would be temporary. A forest depends on the biodiversity of genes to keep insects or disease from finding a weak point to exploit. On finding some weak point to exploit and having hundreds or thousands of identical trees would mean dead spots in the forest. A dead spot would have two risks: forest fire and blow downs. Blow downs because redwoods don't have tap roots. Redwoods interlock their roots with the trees next to them. Which is partly why redwoods mostly grow together.
