A 130-year-old dying giant sequoia tree planted by naturalist John Muir at his Martinez home has been successfully cloned.

A Michigan tree-cloning organization collected cuttings from the tree earlier this year, and it says roots have begun to grow.

The 75-foot tall tree is dying from two regional fungal diseases.

It is possible the new trees may become infected with the disease, said Keith Park, a horticulturist and preservationist at the John Muir Historic Site.

Still, he said attempting to preserve the tree was an important part of keeping a historic link to Muir at the naturalist's former home in Martinez.

David Milarch of the Archangel Ancient Tree Archive, the group cloning the trees, says the clones are living links to Muir's life.
